“The new building is like a blank canvas so we can set everything up exactly the way we want, so we’re very excited about it.”

It was as sentiment endorsed by the American Managing Director, Jeff Wirth, who said: “This investment has been a long time coming, with six years of preparation and teambuilding leading up to this moment.

“Our Kinmel Bay team, known for their rotary dressers, has already started producing electro-plated products on a small scale.

“Moving to the new building that’s nearly three times the size will give us the space to expedite that process. Additionally, we plan to manufacture two vitrified products and a hybrid product in the new space.

“This is a big step and it goes hand in hand with the expansion we’re doing in the United States.

“It comes down to Nick having a belief in the people and the team. This is going to put rocket boosters under the company to continue with the growth trajectory.

“With everything consolidated under one roof, we will get to lay it out to maximise efficiency instead of having to work around the nooks and crannies of the current building.

“The accommodation will also be improved for the employees with nice fresh locker rooms and a cafeteria.

“Nick has a supercharged, can do mentality and we expect to be up and running in the new building in the first quarter of next year.”

According to Finance Manager Michaela Lawton, the Kinmel Bay staff  were delighted to have the opportunity to finally meet Nick and Shane in person.

She said: “We have a solid leadership team here and a fantastic workforce that has the full backing of our American owners and it’s clear that the team here has proved itself worthy of this massive investment.

Essential Role of Diamond Rotary Dressers in Precision Grinding

Grinding wheels, essential for precision manufacturing and shaping of materials, inevitably wear down with use. This wear occurs due to the abrasive action against hard materials, causing gradual degradation of the wheel’s surface. Over time, the cutting edges of the abrasive particles dull, and the bond holding these particles in place can break down, leading to a loss of material from the wheel. This wear not only reduces grinding efficiency but also affects the accuracy and finish of the ground parts.

"Every grinding wheel, whether it be conventional or superabrasive, requires dressing to maintain its profile and cutting performance. Rotary Diamond Dressers are especially useful for precision applications, when you're trying to achieve micron-level tolerances," explains Ed Pitock, Production Manager for Rotary Diamond Dressers.

The Best tool for Grinding Wheel maintenance

Types of Diamond Rotary Dressers

There are two primary types of diamond rotary dressers, also called diamond rolls:

• Traverse-Style Diamond Rolls: Move across the grinding wheel, providing a comprehensive dressing solution. Often a single traverse-style dresser can be programmed for use with many different profiles.

• Plunge-Style Diamond Rolls: Plunge directly into the grinding wheel, offering uniform dressing of a single precise profile for a specific application.

At Continental Diamond Tool, we custom design both types for our customers to meet the requirements of their processes, machines, and part specifications. This ensures that the desired surface finish and geometry are consistently achieved.

Bond Structures

The bond structure in Diamond Rotary Dressers refers to the material and method used to hold the abrasive diamond particles in place. The bond structure determines the strength, durability, and performance characteristics of the dresser. There are different types of bond structures, each suited for specific applications:

• Infiltrated Bond Structure: Also known as sintered, this structure involves filling the spaces between diamond particles with a powdered metal that is then sintered. It is known for its robustness and longevity, making it suitable for demanding applications.

• Reverse Plated Bond Structure: In this method, diamond particles are electroplated with a layer of nickel. While not as durable as infiltrated bonds, reverse plated bonds allow for more complex geometries and are used for specialized applications.

CVD Inserts

In the context of Diamond Rotary Dressers, CVDs refer to Chemical Vapor Deposition diamonds. These synthetic diamonds are created in a controlled environment, allowing for the production of high-purity and high-quality diamond material. Advantages include:

• Purity: CVD diamonds have fewer impurities compared to natural diamonds, resulting in reliable and predictable performance.

• Consistency: The controlled manufacturing process ensures uniformity and consistency in diamond quality for reliable results.

• Customization: The CVD process allows for the production of diamonds with specific properties that are advantageous to industrial applications. This material can also be cut into specific sizes and shapes for reinforcing of a high wear areas or used as the main lot abrasive in the roll.

CVD diamonds are sometimes added to Diamond Rotary Dressers due to their unique properties, including exceptional hardness, wear resistance, and thermal conductivity. By incorporating CVD diamonds, rotary diamond dressers become a powerhouse in micron-scale precision, superior durability, and enhanced efficiency, making them ideal for highly demanding dressing applications.

Industrial Applications

Diamond Rotary Dressers are utilized across various industries, offering precise solutions for different needs. Key sectors include:

• Automotive: These dressers ensure that automotive components meet stringent tolerance requirements, contributing to the reliability and performance of vehicles.

How to Dress a Vitrified CBN Grinding Wheel with a Diamond Rotary Dresser

If you work in manufacturing, particularly in the specialized area of precision grinding, it cannot be overstated the importance of wheel dressing to maintain operational efficiency and product quality. In this comprehensive guide, we will look at the best techniques for traverse dressing a vitrified cubic boron nitride (CBN) wheel using Rotary Diamond Dressers. In Episode 5 of The Grinding Chronicles, CDT Product Manager Troy Giacherio details the specific parameters and most important factors necessary for achieving peak performance in dressing and truing operations. Watch Troy’s video or read on to learn more.

The Grinding Chronicles - Episode 5

Best Techniques for Success When Dressing a Grinding Wheel

Before plunging into the specifics of dressing a Vitrified CBN wheel, it's imperative to understand the dichotomy between two fundamental processes: truing and dressing. Truing involves sculpting the shape or profile of the grinding wheel, while dressing focuses on sharpening the wheel and removing accumulated debris. While diamond rotary dressers serve both functions, understanding this distinction facilitates the implementation of effective dressing strategies.

Essential Parameters for Dressing Success

There are four key parameters to measure for optimizing the dressing of a grinding wheel:

• Velocity Ratio At the heart of dressing lies the velocity ratio, calculated by dividing the velocity of the diamond roll by the velocity of the grinding wheel. This parameter holds significant importance in dressing operations. For Vitrified CBN wheels, the recommended velocity ratio stands at 0.8. Maintaining this ratio ensures that the diamond roll adeptly removes the bond material, laying bare fresh abrasives for optimal grinding performance.

  Overlap Ratio The overlap ratio describes the velocity at which the diamond dresser traverses the wheel's face to sculpt its profile and hone its edge. For Vitrified Bond CBN wheels, an overlap ratio ranging between 2 to 4 is ideal. Sustaining a steady pace ensures a seamless traversal across the grinding wheel. It is important to prevent the dresser from dwelling in any single spot to guarantee uniform dressing proficiency.

  Depth of Dress The depth of dress measures the extent to which the diamond roll plunges into the grinding wheel, thereby dictating the volume of material extracted per pass. When it comes to Vitrified CBN wheels, we recommend a precise depth of dress set at 0.0002 inches per pass. Adherence to this specification not only optimizes grinding efficiency and minimizes downtime, particularly in high-volume production environments, but also preserves the longevity of the grinding wheel, yielding an optimized return on investment.

  Dress Interval The dress interval is defined as the frequency at which the grinding wheel needs dressing, and it is closely tied to the application at hand. Unlike their conventional abrasive counterparts, Vitrified CBN wheels do not require frequent dressing. On the contrary, it is not uncommon to grind hundreds of parts between each dressing session. However, it is important to remain vigilant. Keep an eye on the process and be prepared to adjust the dress interval if part quality diminishes.

When Should I Dress My Grinding Wheel?

Dressing frequency varies depending on several factors specific to your process. Here are two key indicators to monitor in order to assess grinding efficacy and determine when it's time to dress your grinding wheel.

• Power Draw The power draw during grinding operations can be a reliable indicator for grinding wheel dressing. A drop in power draw signals that the wheel is cutting freely, with utmost efficiency, while an uptick in power suggests a looming need for dressing. Neglecting timely dressing can lead to issues such as burn or unwanted variations in surface finish. That’s why it is important to keep a close eye on power draw dynamics to prevent such issues.

• Surface Finish The surface finish of machined parts relies heavily on consistently high levels of grinding performance. A well dressed wheel produces exceptional surface finishes characterized by minimal variations and unyielding consistency in part quality and dimensional accuracy. Therefore, regular dressing sessions conducted with meticulous technique are essential for maintaining superb parts quality and excellence.

Troubleshooting and Optimization

If you are still experiencing issues such as finish patterns or burn despite adhering to prescribed dressing parameters, it may be time to call in the assistance of an expert. Companies like Continental Diamond Tool have application engineers who are trained to analyze grinding processes, pinpoint underlying issues, and facilitate optimization for enhanced performance. Armed with a portable grinding lab, these experts bring their expertise on-site to meticulously evaluate coolant delivery systems, fine-tune machine settings, and traverse a gamut of other variables to resolve persistent challenges. With their help, you can galvanize productivity to unprecedented heights.

Mastering Wheel Dressing

Proper dressing of a Vitrified CBN grinding wheel with a Diamond Rotary Dresser is the key to optimal grinding performance and part quality. By incorporating the parameters and techniques we’ve outlined in this article, manufacturers can achieve reductions in downtime, extension of wheel life, and unwavering consistency in high quality results. 

Additionally, by closely watching power draw and surface finish, you will know when it is time to dress before problems get out of hand. With consistent dressing, and seeking expert help when needed, companies can overcome grinding challenges and greatly improve productivity.

Whether transitioning from conventional abrasives to CBN or seeking to refine existing grinding processes, mastering proper dressing techniques with Diamond Rotary Dressers holds the key to consistent and dependable success.

It makes a range of highly specialised diamond tools for advanced manufacturing industries, including the aerospace, automotive, medical and semi-conductor sectors.

Rhys said: “I saw the story about the company being under new American ownership and I was looking for work experience for my CV so I emailed in an application and they came back to me straight away.

“They’ve given an eight-week programme so I go in one day a week and I’m going through the different processes they do and they show me and explain how they work.

“One Wednesday I was actually working on putting the diamonds into the tooling. It’s been a brilliant opportunity.

“I’ve always been interested in cars and how machines work and I’m doing engineering in sixth form and go to the Llandrillo College campus in Rhyl every Thursday which is really helpful.”

Rhys often works alongside Corey Jones, 19, also from Kinmel Bay, now in his second year as an apprentice who also took the work experience route to a place with CDT.

He said: “I did my A-levels at Eirias High School in Colwyn Bay and then did Level Three Engineering at Coleg Llandrillo’s site at Rhyl with work experience here and they offered me an apprenticeship.

Apprentices get to experience hands-on learning and use their engineering skills in real world applications.

“They wanted me to get used to what’s involved so I worked here through my summer holidays and started my apprenticeship in September in Level Four Engineering.

“I knew there was a lot of maths in engineering and I’d always enjoyed that and I like to challenge myself by learning about the different machines so I’m really enjoying it.

“I had tried a few places for work experience and Coleg Llandrillo suggested here and it’s been brilliant.

“The people here are really great and very knowledgeable with lots of experience you can learn from – I work with someone who has experience on every machine and he’s a big help.

“We’re working for businesses like Rolls-Royce which is fantastic so I want to do the best I can and really build a career here.”

Michaela Lawton, CDT Finance Manager, said: “We have been running an apprenticeship scheme here for a long time and historically it’s been successful and two of our apprentices who moved on after a few years have actually come back to us.

“We have a very good relationship with Coleg Llandrillo and it really helps that they have a campus at Rhyl with a strong and well-equipped engineering department.

“What we do here is so unique and so niche that we expect our apprentices to learn the core skills in college to give them the platform to build on with the highly specialised work we do here.”

CDT has been boosted by a £1.6million investment by their American owners and has opened a second production unit on the Tir Llwyd Estate to house its new electro-plating operation which has received support from Welsh Government.

More than 60 per cent of the company’s products are exported to 30 countries, with sales growing particularly strongly across Europe and Asia, as well as North America.

The company, which celebrates its 40th anniversary this year, was founded originally as Consort Precision Diamond and in 2018 was bought and rebranded by Continental Diamond Tool Corporation, based in New Haven, Indiana.

(From left to right) Justin Hughes, David Morris, Peter Hughes, Stephen Noakes, and Michaela Lawton with Stephen’s inscribed nickel-plated mould, which was presented to him as a retirement gift at the celebration in December of 2023.

A specialist engineering company that keeps the world’s airlines flying will reach new heights thanks to investment from its new American owners, according to one of the firm’s founders. 

Former production director Steve Noakes, 67, from Trefriw, in the Conwy Valley, was speaking at a presentation ceremony to mark his retirement from Continental Diamond Tool in Kinmel Bay which is celebrating its 40th anniversary this year.

Among his leaving gifts was a nickel plated version of the graphite mould for a diamond rotary dresser of the type used to grind the turbine blades of Rolls Royce aero engines, with the signatures of each of his 40 colleagues engraved onto it. 

Steve was one of the eight people who established the niche company as Consort Precision Diamond in 1984, specialising in the manufacture of diamond-encrusted rotary dressers and grinders.

The firm – still one of only two similar companies in the UK – supplies a range of manufacturing sectors, including aerospace, automotive, medical and semi-conductors.

It’s products are used in Boeing 777 and 787 Dreamliner aircraft, as well as the Airbus range A330-A380 whose wings are made at the giant Airbus factory in Broughton.

The company was acquired and rebranded in 2018 by American outfit Continental Diamond Tool which has its headquarters in New Haven, Indiana.

Father-of-two Steve was the last man standing because all the other members of the original team had already retired.

He left “safe in the knowledge” that the company was in good hands. having seen the new management team investing £1.6 million to launch a second production line to make electro-plated grinding wheels, with record profits and sales soaring by 70 per cent.

Steve said: “I am extremely proud of what we have achieved, employing people for 40 years in skilled, well paid jobs.

“I’m also very proud that we’re now part of Continental Diamond Tool. Acquisitions can be messy affairs but this was actually a really happy process.

“They have the same mindset as a family-oriented company, looking after their employees and building a successful business with a very good future. The fit is excellent because they can invest more than we were able to as an independent company.”

He was delighted by the “perfect” gift of the inscribed nickel-plated mould which was presented by his old boss, the original managing director, Dave Morris, who came back for the emotional occasion.

He said: “Steve made a huge contribution – he’s a real diamond. In one sense this is a sad day but it’s also a good one for him because we know our legacy is safe. They’re a good bunch of people.”

There were also good wishes from CDT president, Nick Viggiano, who said: “We will always be indebted to Steve and his fellow founders for their grace, helpfulness and goodwill in managing the transition to the new ownership.

“Steve played an integral role in building a very successful company with a global reputation for excellence in a very competitive niche market. He should be incredibly proud of what he achieved.”

The current managing director, Jeff Wirth, adds, “We are determined to build on those firm foundations and continue to grow and prosper as we look forward to the next 40 years of success.” 

The baton has also been passed to current production manager Justin Hughes, son of the firm’s original technical director, Peter Hughes.

He said: “We now have backing behind us which enables us to push forward and aim at new markets because we have a big safety net behind us.  It gives us reassurance.

“I spoke to our new managing director, Jeff Wirth, who was incredibly complimentary about the existing workforce and said how brilliant it was and the high level of skill and work ethic here.”

It was a sentiment echoed by finance manager Michaela Lawton who said: “We have a lovely team here and everyone’s really very excited about the future.

“We’ve had an investment of £1.6 million and the company’s been on an upward trajectory in terms of growth, turnover and profit and being able to diversify our product range is the next step forward.

“It’s great for Steve, who’s been with the company from the very beginning, to see that that the company is going to continue to grow and expand into new markets.

“Every business goes through a life cycle and the acquisition happened at a perfect time with the original founders reaching retirement age. It was a marriage made in business heaven and the sky’s the limit.”

Mastering Precision Grinding with Diamond Rotary Dressers for Plunge Dressing

When it comes to precision grinding, achieving exceptional accuracy and control is paramount. One of the key techniques that enable this level of control is Plunge Dressing through the use of a precision diamond rotary dresser. In this blog, we will explore Plunge Dressing and the crucial role it plays in the high tech manufacturing industry. We will also take a step back in time to uncover the history of this essential tool.

Understanding Plunge Dressing

Plunge Dressing is a specialized method used in precision grinding requiring the tightest tolerance controls. The process involves “plunging” a precision rotary diamond dresser with the form of the finish part vertically into the grinding wheel. This approach allows for a mirror image of the part to be put into the grinding wheel which is then used to grind the finished parts to the highest levels of accuracy achievable.

The History of Plunge Dressing

Plunge Dressing, in its essence, is as old as precision grinding itself. It evolved alongside the broader history of abrasive tools and precision engineering, with the diamond rotary dresser as a key component.

The roots of Plunge Dressing can be traced back to the early days of industrialization when grinding processes were becoming essential for the production of precision components. As the manufacturing industry advanced, the need for higher precision, tight tolerances, and complex profile (geometry) control became apparent. This led to the development and refinement of techniques, including the use of the precision diamond rotary dresser or diamond dressing wheel, to enhance the grinding process.

Since 1984, Continental Diamond Tool Limited, then called Consort Precision Diamond Company, has been making precision Hand-Set “Sintered” Rotary Diamond dressers. In 1995, CDT LTD made waves with its development of an electroforming process that greatly reduced the process time for Reverse Plated Diamond Rotary Dressers. With these advances and revolutionary technology in both Sintered and Reverse Plated manufacturing methods, precision Rotary Dressers are now more affordable and accessible to a greater number of industries.

The Benefits of Plunge Dressing with a Diamond Rotary Dresser

Plunge Dressing with diamond rotary dresser, offers a range of benefits that make it a preferred choice in precision grinding:

1. Precise Profile Control: Plunge Dressing with a diamond rotary dresser enables the precise shaping of intricate profiles on workpieces. This level of control is invaluable in applications where tight tolerances and intricate shapes are required with tolerances of 1um or better.

2. Reduced Heat Buildup: The controlled plunge of the diamond rotary dresser results in precise truing and conditioning of the grinding wheel.  This is especially important for materials that are sensitive to heat, helping to prevent thermal damage and maintain workpiece integrity.

4. Consistency and Quality: Plunge Dressing with a diamond rotary dresser ensures consistency in material removal, resulting in a high-quality surface finish on workpieces. This consistency is crucial for producing precise components with minimal variation.

The Mechanics of Plunge Roll Dressing

Plunge roll dressing involves a specific mechanical process. Here's a glimpse of how it works:

1. Preparation: To start, the diamond rotary dresser is set up and aligned with the grinding wheel.

2. Vertical Movement: Then the dresser is moved vertically into the spinning grinding wheel. The depth of penetration is precisely controlled to ensure the desired material removal.

3. Material Removal: As the diamond rotary dresser engages with the grinding wheel, it removes material from the wheel's surface. This process allows for the desired profile or shape to be formed on the wheel.

4. Controlled Withdrawal: After the material removal process is complete, the diamond rotary dresser is withdrawn from the grinding wheel. This is done with the same level of precision and control to maintain the desired profile.

APPLICATIONS for Plunge Dressing with a Diamond Rotary Dresser

Plunge-style diamond rotary dressers find applications in many industries, such as:

Aerospace: In the aerospace industry, where precision and tight tolerances are paramount, plunge dressing with a diamond rotary dresser is used to shape critical components for aircraft and spacecraft.

Medical Devices: Plunge-style diamond rotary dressers are essential for creating intricate and precise components in medical devices to ensure their safety and effectiveness.

Automotive: This type of diamond rotary dresser is regularly employed to craft precision parts for the automotive industry, contributing to the performance and longevity of vehicles.

IN SUMMARY

In the world of precision grinding, plunge dressing with a diamond rotary dresser stands out as a technique that empowers manufacturers to achieve the highest levels of precision and quality. Its control and consistency make it an invaluable tool for industries where tight tolerances and intricate profiles are the order of the day.

Our Consort Precision™ line of Diamond Rotary Dressers offers versatility in design, with custom plunge form dressers available in sintered or reverse plated variants. The plated plunge form rotary dressers have the extra benefit of being able to hold tighter tolerances, where as Sintered Rotary Dressers can have shorter lead times and hold up better in rough environments.

The Story Behind Our Precision Grinding Solutions at Continental Diamond Tool Ltd.

At Continental Diamond Tool Limited, our 40 years of success has been built by delivering the finest custom Diamond Rotary Dressers available in the market. Also called Diamond Rolls, these tools are used extensively in a growing number of grinding operations to primarily facilitate the transfer of highly accurate repeated configurations onto components. What makes a Consort Precision Diamond Rotary Dresser stand out can be summarized in four key aspects: technology, expertise, process, and quality or product excellence. As we have expanded into other product lines, we bring that same commitment to every precision grinding product we produce.

Cutting Edge Technology

In a plunge-style dresser the Rotary Diamond Dresser is mounted onto a spindle of a drive unit which in turn is mounted onto a slideway arrangement that allows the formed periphery of the dresser to infeed into a grinding wheel, thereby transferring the desired shape into it. The form, or configuration, can then be 'ground' on to the component. Plunge dressers are especially accurate for precision grinding as there is no lost form or geometry due to machine movements. Plus, the dressers can be held to submicron levels of accuracy.

Traverse dressing is a grinding wheel dressing technique where the diamond rotary dresser traverses across the surface of the grinding wheel to create a specific profile or shape. Traverse Disc Dressers allow you the flexibility to make profile changes or dress in completely new profiles with the same tool, reducing down time for wheel change overs or roll changes.

INDUSTRY EXPERTISE

Such Industries as the Automotive and Aerospace as well land based Turbine Engine production units employ large quantities of Rotary Diamond Dressers. Typically, within the Aero manufacturing industry, such components as Turbine Blades and Nozzle Guide Vanes as well as Flap Actuating Shafts require their intricate features to be ground with grinding wheels that have been formed with Rotary Diamond Dressers. As can be seen reference is made on our following pages to the many applications within the automotive industry.

CDT Ltd. can offer expertise in the selection of the most appropriate type of Rotary Diamond Dresser by reference to the configuration required and to the grinding machine on which it is to be used. Basically, three processes are employed. Handset Sintered, Random Set Sintered and Reverse Plated. Within each of those categories, selection of diamond type and their placement into the periphery of the Rotary Dresser, plays a major part in determining its operational life and performance. Even before its establishment in 1984, the company’s principals and a large proportion of its employees had many previous years experience in the manufacture of Rotary Diamond Dressers. Bringing with them unique knowledge of the industry, CDT Ltd. — then Consort Precision Diamond — quickly established itself with this one product into the global market of prime and subcontract component manufacturers, earning the respect of competitors and customers alike.

AWARD-WINNING PROCESSES

In respect to the Reverse Plating technique, at Continental Diamond Tool Limited we are particularly proud of the fact that we have been awarded the accolade of winning the BOOST award in the U.K. in 1995 for the design and development of a high speed plating process which dramatically reduced previous lengthy plating times. This achievement gave us a competitive edge against alternative suppliers and satisfied the reduced lead times that customers continue to demand. In the same period, we gained the S.M.A.R.T 1995 award for the development of the electroforming process as an acknowledgement of the reduction in the process time employed in the manufacture of Reverse Plated Rotary Diamond Dressers. CDT Ltd. proudly holds the ISO 9001:2015 Registration Certificate for its Quality Management Systems.

Mastering Precision: How Traverse Diamond Dressing Enhances Grinding Wheel Performance

Precision in manufacturing is the key to producing high-quality components across various industries, from automotive to aerospace, and even in everyday consumer products. One crucial aspect of achieving this precision is the performance of grinding wheels. In precision grinding operations, where the tolerances can be incredibly tight, grinding wheel performance is paramount. Enter the Traverse Diamond Dresser, a type of diamond rotary dresser that plays a pivotal role in ensuring that grinding wheels are in top form. In this blog post, we will delve into the world of Traverse Disc Dressers and explore how they enhance grinding wheel performance.

The Basics of Traverse Diamond Dressing

The Traverse Disc Dresser is an indispensable wheel profiling tool in the realm of precision grinding. Also referred to as Diamond Wheel Dressers, they are designed to dress and shape profile grinding wheels to maintain an optimal condition. The dressing process involves the removal of abrasive material from the grinding wheel's surface, which can become uneven, clogged, or worn over time due to the abrasive grinding process.

Here's how Traverse Disc Dressers work their magic:

1. Material Removal: These dressers feature a wide range of diamond sizes and grades to achieve the desired dressing condition. As the rotary diamond dresser traverses across the grinding wheel's surface, it precisely and efficiently removes small amounts of abrasive material. This effectively 'cleans' the wheel, restoring its cutting ability.

2. Wheel Truing: One primary function of Traverse Disc Dressers is truing the grinding wheel. Over time, grinding wheels can develop irregularities, affecting the precision of the grinding process. The dresser ensures that the wheel runs true and maintains a consistent, flat or cylindrical shape, depending on the application.

3. Form Dressing: In precision grinding, some applications require intricate shapes or profiles to be ground onto workpieces. Traverse Disc Dressers can be employed for form dressing, which shapes the grinding wheel to match specific profiles with utmost precision.

Achieving Superior Grinding Wheel Performance

Now that we understand the role of Traverse Disc Dressers let's explore how these wheel profiling tools enhance grinding wheel performance:

1. Consistency is Key: Precision grinding demands consistency. Traverse Diamond Dressing ensures that the grinding wheel profile remains uniform in shape, minimizing variations in the workpiece's finish and dimensions. This consistency is essential for meeting tight tolerances.

2. Optimized Material Removal: Dressing the wheel not only ensures precision but also optimizes material removal rates. It enhances the wheel's cutting ability, reducing heat generation and the risk of burning the workpiece—a common issue in precision grinding.

3. Reduced Scrap Rates: With a properly dressed grinding wheel, the likelihood of producing defective or out-of-spec parts is significantly reduced. This translates to lower scrap rates and higher yields, ultimately improving the bottom line.

4. Versatility: Traverse Disc Dressers are versatile tools suitable for various grinding applications. Whether you're grinding metals, ceramics, or other materials, these dressers can be adapted to meet your specific needs.

5. Flexibility: Change parts/profile shapes frequently?  Traverse Disc Dressers allow you to quickly and easily make profile changes or dress in completely new profiles without making grinding wheel changes, saving you down time for wheel change overs and/or roll changes.

Applications for Traverse Disc Dressers

Traverse Disc Dressers play a pivotal role in a multitude of precision-driven industries. These grinding wheel truers are essential for maintaining and shaping grinding wheels, ensuring that precision grinding processes yield consistent and accurate results.

Diamond Rotary Dressers by Type

Industry's increasing demand for high-accuracy, high-speed production has fostered a new branch of engineering technology to ensure grinding wheels are maintained in optimum condition. Diamond Rotary Dressers are now recognised as the most efficient and economic means of dressing and truing grinding wheels to the correct form, tolerance and condition. Their use is growing rapidly in the manufacture of components for automotive, aerospace, power generation, machine tool and precision engineering industries.

Leading in innovation

At Continental Diamond Tool Limited, we have been a frontrunner for decades in innovating rotary dresser technology. As far back as 1995, as Consort Precision Diamond Company, we won industry awards for our development of the high speed plating process which dramatically reduced previous lengthy plating times and is still in use today. We proudly holds the ISO 9001:2015 Registration Certificate for its Quality Management Systems, and we are continuously innovating to increase the efficiency and cost effectiveness of this industry-changing technology.

OUR FOUR MAIN PROCESSES

There are four distinct methods we use in the manufacture of our diamond rotary dressers: reverse plated, hand-set sintered, cvd sintered, and random set sintered. Each has its own benefits, as outlined below.

---

Type 1 - Reverse-Plated

The High Accuracy dresser

Reverse Plated Dressers are selected where high accuracy of profile detail is required together with a correspondingly high quality surface finish on the component.

Accuracy is achieved by centrifugal dispersion of the specially selected diamonds onto the walls of a mould. These are secured by our electro-deposition process that has won acclaim through the acquisition of industry awards, thereby achieving the short lead times so often required by customers.

The electro-deposition process is stable and unaffected by shrinkage, which results in Rotary Diamond Dressers of exceptional accuracy.

Tolerance Detail

General Surface Finish Produced: 0.4uM. 16 C.L.A.

Typical Applications

• Turbine Blade - Fir Tree Root Form

• Cam Grinding

• Bearing Industry

• Ball Joints

• Needle Injectors

---

Type 2 - Handset Sintered Dressers

A CONSORT PRECISION™ SPECIALTY

Of all the rotary dressers for which the Consort Precision name is known, Handset Sintered Dressers are our most popular type. These custom diamond rotary dressers cover many applications where robustness is required and the general tolerance is open.

As the name implies, diamonds are selected and set by hand in a mould, then secured in position by sintering in a tungsten based matrix. Allowances are made for consequential shrinkage to bring the finished dresser within specification tolerances.

Tolerance Detail

General Surface Finish Produced: 0.8uM. 32 C.L.A.

Typical Applications

• Turbine Blade

• Automobile Valves

• Crankshafts

---

type 3 - CVD Sintered

THE High Performance Dresser

Our CVD sintered rotary diamond dressers have very high thermal oxidation resistance and other excellent thermal properties. CVD is perfect for secure mounting with traditional non-ferrous metal sintering. CVD sintered rotary diamond dressers can also be brazed onto a dresser body using an active braze alloy in a non-oxidizing environment.

Benefits

• Highly resistant to chipping and fracture

• Wears evenly over the dresser's entire length

• Performs regardless of dressing orientation

• Outstanding thermal stability

CVD diamond can be manufactured in a multitude of shapes, sizes, thicknesses and grades giving engineers great flexibility with this material's extreme properties. 

Dimensions

Our CVD diamond dressers can be ordered in all the standard rectangular dimensions in various lengths and square, but we also specialize in supplying non-standard custom dimensions upon request.

Typical Applications

• Metal matrix composites

• Aluminium alloys

• Glass-reinforced plastics

• Carbon fibre-based materials

• Plastics and rubbers

• Graphite

---

type 4 - random set sintered

The dresser FOR QUICK DELIVERY

Random Set Sintered Dressers are most suitable where openness is required, coupled with a tight form and improved surface finish. 

Very often selected diamonds are strategically placed in the mould to support the form in vulnerable areas. The remaining area is then in-filled by centrifugal dispersion of diamonds and sintered.

Random Set Sintered Dressers have the advantage that they can be delivered quickly to meet urgent customer requirements.

Tolerance Detail

General Surface Finish Produced 0.4 uM. 16 C.L.A.

Typical Applications

• Automobile Valves

• Turbine Root Forms

• Flute Grinding

What Is a Diamond Rotary Dresser?

Grinding operations often work best with some form of wheel dressing to re-establish the wheel profile and/or recondition the wheel face. Wheel conditioning typically involves the sharpening and opening of the wheel face, while also removing dull abrasives, excessive bond, and workpiece material (loading). A sharp and open wheel face will allow maximum possible material-removal rates and reduced thermal stress on the workpiece. CDT engineers design each dresser to match your wheel topography so that it performs with superior strength and versatility. All are made with the highest quality CVD, natural diamond, synthetic diamond and combinations to maximize performance and roll life. Because they are custom manufactured, an abundance of configurations are possible.

Types of Diamond Rotary Dressers

There are two manufacturing methods for rotary dressers with several variations in setting/diamond application to best suit the customer application.  Below are several examples:

1. Reverse Plated Diamond Roll

Manufactured with high accuracy molds and a tightly controlled electroplating process to deposit the nickel layer.  The nickel layer holds the abrasive in place to allow for extremely complex profiles and tight tolerance work, which produce high quality surface finishes.  Because of the accuracy on the front end of the process, these rolls require little to no surface conditioning, which leave sharp natural points for superior dressing, resulting in an open grinding wheel and lower grinding forces.  Reverse plated rolls are ideal for continuous dress creep feed process, and complex forms like bearings, fuel injection, thread forms, and aerospace root forms. 

2. Sintered Diamond Roll

Using a high temperature powdered metal process to create a tough tungsten matrix to secure the abrasive in the roll.  This product is ideal for aggressive grinding and harsh working environment, while still holding tight profile tolerances and complex forms.  These are all handset products, either pattern set or random set, to allow for a wide range of options on performance, surface finish, and roll life.  Because of the manufacturing process, these rolls generally have shorter lead times and can usually be reworked to meet production demands.  Sintered rolls are ideal for simple profile rolls to complex valve grinding assemblies.

3. Sintered CVD / Disc Dresser

These dressers use the same tough tungsten matrix as the standard Sintered rolls but are unique in the abrasive they are set with and how they are typically used.  They are available using synthetic, natural, or CVD abrasive and can be set in combination to target specific performance, surface finish, and roll life.  These are typically used to traverse across the grinding wheel to generate specific profiles and wheel conditions for open and free cutting grinding of the part.  This style dresser is ideal for reconditioning, which can restore the roll to its original profile and tolerance in half the normal lead time and a fraction of the cost.

5 Factors for Best Dressing Performance

The intricacies of selecting the ideal rotary diamond dresser for your unique application depend on many factors like tolerance, surface finish, configuration of form, grinding machine type, and grinding wheel specification. Continental Diamond Tool (CDT) has extensive experience in designing and crafting dressing solutions that perfectly suits your needs. Customization is key. Read on to discover how tailoring a diamond rotary dresser to your process can improve grinding performance.

Plunge dressing vs. Traverse dressing

Traverse dressing and plunge dressing are two methods that employ diamond rotary dressers in precision grinding applications. Each dressing technique requires a different form to serve its unique purpose.

Traverse dressers are designed to move across the surface of a grinding wheel, gradually shaping and refreshing its profile to maintain consistent performance and geometric precision. This method is ideal for applications where maintaining a constant wheel profile is crucial, such as in high-precision cylindrical grinding.

On the other hand, plunge diamond rotary dressers are employed to create specific, intricate profiles or contours in a grinding wheel. By plunging the dresser directly into the wheel, they generate complex shapes and features with precision. These dressers are particularly valuable in applications requiring customized workpiece forms, like gear grinding or aerospace components.

Both methods play a vital role in the manufacturing industry, ensuring the optimal condition and shape of grinding wheels. This, in turn, guarantees the quality and accuracy of the finished workpieces.

DIAMOND ROTARY DRESSER TYPEs

The diamonds in Diamond Rotary Dressers are what give this technology its cutting edge. There are four unique processes that can be used to adhere the diamonds to the dresser form:

• REVERSE PLATED - Reverse Plated Dressers are best suited for applications where high accuracy of profile and a correspondingly high quality surface finish on the component are required.

• HANDSET SINTERED - Handset Sintered Dressers are our most commonly used type of Rotary Diamond Dresser. They cover applications where robustness is required and the general tolerance is open.

• CVD SINTERED - CVD Sintered Dressers are highly resistant to chipping and fracture, and they wear evenly over the dresser’s entire length. They also have outstanding thermal stability in use.

• RANDOM SET SINTERED - Random Set Sintered Dressers are perfect for applications requiring openness, tight form, and improved surface finish. They can be delivered quickly to meet urgent demand.

Sometimes called Truers or Rollers, how do you know which of these will be the best diamond rotary dresser type for your application? Especially when each of these categories contain many further variables of appropriate diamonds and setting patterns.

5 factors for proper dresser selection

Proper dresser selection starts with investigating these five factors. Every well designed dressing tool must meet the specific requirements of these areas:

• TOLERANCE - Tolerance refers to the allowable deviation or variation from a specified measurement or dimension in a workpiece. In the context of dressing tools, it's essential to consider the level of precision or accuracy required in the dressing process to meet the desired workpiece tolerances.

• SURFACE FINISH - Surface finish pertains to the quality and texture of a workpiece's surface after the grinding or machining process. When designing a dressing tool, you need to account for the desired surface finish, which can range from rough to smooth, as it influences the choice of abrasive grains and dressing techniques.

• CONFIGURATION OF FORM - Configuration of form relates to the specific shape, contour, or profile that the dressed grinding wheel should have. It encompasses the design and geometry of the wheel, which needs to be precisely replicated by the dressing tool to achieve the desired workpiece shape or finish.

• GRINDING MACHINE TYPE - The type of grinding machine used in a particular application, such as cylindrical, surface, or centerless grinding, significantly impacts the dressing tool's design. Different machines require specific dressing techniques and tools to optimize performance and precision.

• GRINDING WHEEL SPECIFICATION - This factor involves the characteristics and properties of the grinding wheel to be dressed. It encompasses details like wheel diameter, abrasive type, grain size, bonding material, and other specifications. The dressing tool must be compatible with these wheel specifications to ensure effective and efficient dressing.

Considering these factors when designing a dressing tool is crucial to achieving the desired precision, surface finish, and workpiece quality in various grinding applications. Correct specification involves the appropriate design, selection and placement of diamonds in a way that takes into account all the factors affecting the individual customer's application. It cannot be achieved by choosing from a small range of general purpose dresser types. Customization is required.
