The Grinding Chronicles - Episode 6

Understanding the Four Common Bond Systems

Resin Bonds

Resin bonds are plastic-based compounds typically made from phenolics or polyimides. These bonds are versatile and can be enhanced with fillers such as copper or silicon carbide to improve performance. The manufacturing process for resin bonds at CDT begins with creating a tailored formulation that includes the bond material, abrasive, and fillers. This dry powder mixture is blended in special tumblers and then carefully and uniformly packed into mold cavities. The molds undergo hot pressing, where temperature and pressure are meticulously controlled to achieve the desired density. Finally, the wheels are finished by machining and grinding them to the specified size and geometry.

Properties and Applications:

• Tough and Durable: Resin bonds are fully dense and easy to use, making them suitable for a variety of grinding applications.

• Versatile: They can work with nearly any material, from hard metals to softer alloys.

• Enhanced Performance: Fillers like copper or silicon carbide can be added to improve heat dissipation and grinding efficiency.

• Wide Range of Applications: Suitable for diverse grinding tasks, including tool and cutter grinding, centerless grinding, and surface grinding.

Metal Bonds

Metal bonds can be composed of various metals, including bronze, copper, and iron, and may sometimes be alloyed with precious metals like silver. Metal bonds are known for their hardness, toughness, and durability, making them ideal for grinding highly abrasive materials such as glass and ceramics. Although metal bonds grind more slowly than other types, they offer the longest lifespan. The manufacturing process for metal bonds at CDT is similar to that of resin bonds, involving formulation, mixing, molding, hot pressing, and finishing.

Properties and Applications:

• Hardest and Toughest: Metal bonds are the most challenging to use but provide superior durability.

• Long-Lasting: They offer the longest lifespan among bond types, reducing the frequency of wheel changes.

• Ideal for Abrasive Materials: Best suited for grinding materials like glass, ceramics, and carbide.

• Durability: Excellent for applications requiring extreme durability and extended wheel life, such as in the automotive and aerospace industries.

Vitrified Bonds

Vitrified bonds are made from glass or ceramic materials, creating a porous structure that significantly reduces grinding force. This allows for higher grinding speeds, making vitrified bonds ideal for high-production applications. These bonds offer moderate to high material removal rates and excellent form accuracy, as they can be dressed and profiled in-process using rotary dressers. The manufacturing process for vitrified wheels at CDT involves formulation, mixing, cold pressing, and a sintering (baking) process to fuse the glass or ceramic together. The final step is finishing, similar to the other bond types.

Properties and Applications:

• Porous Structure: Lowers grinding force and allows increased speeds, enhancing efficiency.

• High Production: Ideal for high-production applications such as automotive part manufacturing.

• Moderate to High Material Removal Rates: Efficient for large-scale operations, balancing speed and precision.

• High Form Accuracy: Can be dressed and profiled in-process using rotary dressers, making them suitable for precise and consistent grinding tasks.

Electroplated Bonds

Electroplated (or plated) bonds consist of a single layer of abrasive held by a nickel-based metal bond. The process begins with machining the desired wheel size and geometry onto a steel wheel core. The non-plated surfaces are masked to prevent unwanted plating. The wheel core is then placed in a bath with a nickel-based solution and the abrasive material. By applying a positive charge on one side and a negative charge on the other, nickel plating is deposited onto the wheel core, causing a single layer of abrasive to adhere. Excess abrasive is removed, and the plating process continues until the abrasive layer is encapsulated to the desired level, typically 50-100% depending on the application. Electroplated products are suitable for complex geometries and low to medium production applications due to their high material removal rates and fast grinding speeds.

Properties and Applications:

• High Material Removal Rates: Provides the fastest grinding speeds, ideal for rapid material removal.

• Cost-Effective: Single layer of abrasive can be stripped and replated, extending the wheel’s life.

• Ideal for Complex Geometries: Precise form replication with minimal finishing, suitable for intricate designs.

• Low to Medium Production: Suitable for specific applications requiring detailed shapes and efficient material removal.

Key Considerations for Selecting the Right Bond System:

Choosing the appropriate bond system for your grinding application is crucial for achieving optimal performance and quality. Each bond type offers unique properties and advantages, making them suitable for different materials and grinding conditions. By understanding the composition, manufacturing processes, and ideal applications of Resin, Metal, Vitrified, and Electroplated bonds, you can make informed decisions to enhance your grinding operations.

Factors in Bond System Selection:

1. Material to be Ground: The hardness and abrasiveness of the material significantly influence the choice of bond.

2. Grinding Speed and Efficiency: Consider whether the application requires high-speed grinding or if longevity and durability are more critical.

3. Application Specifics: Determine if the grinding operation involves complex geometries or requires high form accuracy.

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.

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. If you would like help with your wheel dressing or grinding process, don't hesitate to reach out to our engineering team at TheGrindingChronicles@CDTUSA.net.

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.

Their donation was made to mark the 40th anniversary of this CDT location – one of only two of its kind in the UK that specializes in precision diamond grinding products -  which employs 40 skilled staff at its factory on the Tir Llwyd Industrial Estate in Kinmel Bay.

Helen said: “My parents, Maureen and Ted Felton, from Kinmel Bay, were both here and the care and support the hospice gave was a great comfort to them and to us as a family.

“My mum used to come to the day centre here and made many things I still have at home including a tie-dyed silk scarf.

“Then she was a resident here and was struggling with her mobility and they helped her a lot before she passed away here.

“My dad was in hospital in Liverpool and I asked for him to be moved to Ysbyty Glan Clwyd and they said he only had a matter of days so I requested that he come to St Kentigernand the staff here managed to get him in.

“He knew we were trying to get him here because on one of his good days we managed to tell him and it meant a lot to all of us as a family.

“St Kentigern is a wonderful place and my mum made a lot of friends here. It’s very comforting here and I’m delighted that CDT are supporting it.”

The hospice has been extended to 12 beds from eight but it also provides extensive day care and respite services as well as wide range of therapies and over the past 12 months more than  600 people from across the area have used its services.

They cost £3.6 million a year with three-quarters of that raised by St Kentigern team, of fundraisers who are currently working on one of the year’s major events, the Twilight Trek which takes place on Saturday, June 29.

They also provide a Wish Ambulance which aims to make the final wishes of its residents come true and they have included a lady in her 30s who wanted to spend a final couple of hours in her own home.

Another patient wanted to see a fireworks display for the last time and the Royal National Lifeboat Institute came in to stage a show

CDT are now partnering with St Kentigern to support the hospice and make those dreams come true. You can extend your support, too, by making a donation here.

CDT Finance Manager Michaela Lawton said: “It is a fantastic cause, it’s local and after a discussion with our employees about which charities to support St Kentigern was put forward and it was a no-brainer really.

“I came to visit the hospice and was so impressed by the work they are doing and by the fantastic range of services and activities they provide, not only to their patients but to their families at the most difficult time in their lives.

“This is the 40th anniversary of the company and we want to set up a long-term partnership with St Kentigern to mark that and we aim to support them with regular donations in the future.”

Advanced Nurse Practitioner Becky McNay, from Wrexham, joined St Kentigern four years ago and she said: “It’s been amazing. I’ve really loved it. It’s such a rewarding place to work.

“You can’t just come here to a place like this because it’s a job. You have to really want to do it and it’s really great to build relationships with the patients and with their families because they play such an important role.

“I had always wanted to do palliative care from when I was 16 when my nan came to live with us and she was terminally ill.

“Here’s it’s not just about the process of dying. There’s much more to it than that with respite care and outpatients services and the complementary therapies we offer like massages and a wellbeing programme which covers a different topic each week.

“There’s also now advanced care planning because if someone is diagnosed with a life-limiting illness it’s important to have advice on wills and legal matters and of course it is very rewarding if you can be there for someone emotionally as well.

“I really enjoy the one to one care and the privilege of having time to second with patients and their families – you just wouldn’t get the same amount of time in an acute ward of a hospital.”

The precision manufacturing company was founded in 1984 as Consort Precision Diamond and in 2018 was bought and rebranded by Continental Diamond Tool, based in New Haven, Indiana.

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

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.

Conventional Abrasives vs. Superabrasives

In Episode 4 of The Grinding Chronicles, Continental Diamond Tool Engineering Consultant Jon VanSant investigates  the history of common abrasive materials and their key differentiating characteristics that impact wheel life, cutting performance, and efficiency. Using the wrong abrasive for your application can significantly increase your cost per part. Watch Jon’s video or read the article below to learn the differences between conventional abrasives and superabrasives.

The Grinding Chronicles - Episode 4

Understanding Abrasive Evolution

In the early 1800s, precision grinding relied on naturally occurring abrasives like emery. Fast forward to the late 19th century, and we witnessed pivotal developments with the advent of "Carborundum" or silicon-carbide by Dr. Edward Acheson in 1891, followed by the patenting of 'Alundum' or aluminum oxide by Aldus Higgins in 1904. The landscape changed once again with the introduction of synthetic diamond in 1954 and cubic boron nitride (cBN) in 1957, marking the emergence of superabrasives. Although superabrasives were first synthesized in the 1950’s, it took two decades before commercial products became available.

Distinguishing Characteristics

To understand the difference between conventional abrasives and superabrasives, let’s examine three key characteristics: hardness, thermal conductivity, and friability.

• Hardness: An important consideration in abrasive selection, superabrasives like cBN and Diamond demonstrate superior hardness compared to Aluminum Oxide and Silicon Carbide. This is part of what makes superabrasives super, and makes them particularly efficient when grinding extremely hard materials.

• Thermal Conductivity: Enhanced thermal conductivity facilitates efficient heat transfer during grinding operations, ensuring minimal damage to the workpiece. This is critical where surface finish is concerned.

• Friability: Friability reflects the fracture or impact toughness of an abrasive and underscores another crucial aspect. Analysis reveal a substantial disparity between conventional and superabrasives, with the latter exhibiting remarkable compression fracture strength. When comparing the compression fracture strength of diamond and aluminum oxide at a particle size of 400 microns, there is a 10:1 difference between the conventional abrasive and the superabrasive.

Performance Metrics

Moving beyond physical attributes, an examination of performance metrics such as cut, wear, and dressing efficiency further demonstrates superabrasives prowess. 

• Cutting Efficiency: Superabrasives like Diamond and cBN require less power and force for cutting operations, ensuring efficient material removal. 

• Wear Resistance: Superabrasives demonstrate significantly higher wear resistance, leading to prolonged wheel life and reduced downtime when compared to conventional abrasives.

• Dressing Efficiency: Superabrasives also excel when considering downtime for dressing since they maintain dressing efficiency over extended periods. In some cases, we have seen up to 20 times the parts per dress. With less frequent dressing comes more consistent performance. Plus, you’re only taking off a tenth of the material in dressing, so your wheel lasts much longer. 

Cost Considerations

Superabrasives, with their many advantages, do come with a substantial up-front investment. Even so, many companies see sustainable returns.  

• Long-Term Value: Superabrasives offer enhanced productivity and cost-effectiveness that often results in lower cost per part over time.

• Application Considerations: Recognizing that not every application warrants a superabrasive grinding wheel, factors such as machine tools, fluid compatibility, and work volume must be considered. Superabrasives are most cost effective in high volume, extremely demanding applications.

Coolant Application Techniques to Reduce Wheel Wear and Burn in Grinding

In Episode 3 of The Grinding Chronicles, Continental Diamond Tool Application Engineer Blu Conrad explains some essential aspects of coolant application that can impact your grinding performance. By having the correct placement of coolant lines and optimizing your coolant setup, you can significantly reduce cycle times, minimize wheel wear, and prevent burning during the grinding process. Watch Blu’s video or read the article below to learn how.

The Grinding Chronicles - Episode 3

Coolant Application and Its Impact on Grinding Performance

Most grinding operators know that reducing heat generation in grinding is crucial for avoiding excessive wheel wear and burn. However, you might not be aware of the various strategies available for achieving this goal. In this article, we will explore how coolant application can mitigate these factors.  It starts with four key considerations in cooling: Velocity, Flow, Line Placement, and Temperature.

Velocity Matters

One critical factor in effective coolant application is ensuring that the coolant is spraying at the correct velocity, typically ranging between 70% and 100% of your grinding wheel speed. This velocity is essential because of a force called the air barrier. 

As a grinding wheel rotates, it creates an air barrier around its perimeter. To penetrate this barrier and deliver coolant to the grinding zone, the coolant stream must travel at the appropriate velocity. If it is too slow, the grinding wheel can blow the coolant away. Conversely, if the velocity is too high, the coolant may make contact with the grinding wheel and bounce off, rendering it ineffective in reaching the desired area.

Balancing Flow Rate

In addition to velocity, the amount of coolant flowing from the coolant line, known as the Flow Rate, is equally crucial. Flow rate and velocity are interrelated, and their optimization is a balancing act. 

In grinding, you often have a choice between low-pressure, high-flow setups, or high-pressure, low-flow configurations. If the flow rate is too low, there won't be enough coolant to adequately cool the grinding process, potentially leading to overheating and damage. Conversely, if the flow rate is excessively high, you will be wasting coolant, resulting in inefficiency and increased operational costs.

Utilizing Nozzles for Optimization

A practical approach to achieving the ideal Velocity and Flow is by using nozzles. While standard jet nozzles are suitable for many grinding applications, different grinding processes may require wheels with distinct shapes, such as flat or radial profiles.

In such cases, it is often more effective to employ nozzles and coolant lines that have been specifically engineered, designed, and tuned to accommodate these unique wheel types. This ensures that the coolant is delivered with the appropriate velocity, flow, and, equally importantly, in the correct position.

Positioning and Direction

The position and direction of the coolant are critical factors in coolant application efficiency. Ideally, you want your coolant jet to spray just before the point of contact, where the grinding wheel and workpiece meet. Additionally, the coolant should flow in the same direction as the rotation of the grinding wheel.

If the coolant stream strikes too far above or behind the point of grinding contact, it will fail to effectively enter the grinding zone, missing the opportunity to cool the process where it is needed most.

Achieving Efficiency in Your Grinding Process

Optimizing coolant applications is a fundamental aspect of enhancing the efficiency and performance of your grinding processes. By carefully considering Velocity, Flow, Line Placement, and Temperature, you can significantly improve cycle times, reduce wheel wear, and prevent burning during grinding operations.

At Continental Diamond Tool, we understand the importance of precision coolant applications and many other factors in achieving superior results. Whether you require standard jet nozzles or specialized coolant solutions tailored to your specific needs, we have the expertise and technology to help you isolate those parameters that are holding back your grinding performance.

Part Masking of Plated Grinding Wheels

Part masking is a crucial technique employed in the plating process for CBN (Cubic Boron Nitride) and diamond grinding wheels. This method involves selectively covering specific areas of a metal substrate before plating to protect them from the plating solution. Part masking plays a significant role in ensuring the precision, quality, and functionality of grinding wheels used in various industries, from manufacturing to automotive and aerospace. In this article, we will delve into what part masking is, how it is done, why it is essential in the plating process, and what it takes to excel at this intricate skill.

What is Part Masking?

Part masking is the process of shielding specific areas or features of a substrate to prevent them from being plated during the plating process. It is achieved by applying a masking material to the surface of the substrate in a controlled and precise manner. The masking material can be in the form of tapes, paints, or other coatings that can resist the heat and duration of time in the plating process.

How is Part Masking Done?

The process of part masking involves several steps:

1. Surface Preparation

   Before masking, the metal substrate is thoroughly cleaned and prepared. This step ensures that the surface is free from contaminants, oils, coolants, machining residues and oxides, which can interfere with the adhesion of the masking material.

2. Masking Material Selection

   The choice of masking material depends on factors such as the type of substrate being plated, the plating process used, and the specific areas that need protection. Common masking materials include specialized masking tapes, latex, and resin-based coatings. Continental Diamond Tool employs all of these methods in its process.

3. Application of Masking Material

   The masking material is applied precisely to cover the areas that should not be plated. This can be done manually or using brushes, stencils, scribes or automated equipment. For more complex patterns, careful attention is given to ensure that there are no gaps or leaks in the masking material.

4. Cure or Drying

   Depending on the type of masking material used, it may need to be cured or allowed to dry thoroughly. This step generally takes a specific amount of time and ensures that the masking material remains intact and impermeable during the plating process.

5. Plating

   Once the wheel has been masked and cured, the substrate is immersed in the plating bath, where the exposed areas are plated with the desired abrasive material, such as diamond or CBN particles. The masked areas remain untouched, preserving their original characteristics.

6. Mask Removal

   After the plating process is complete, the masking material is carefully removed, revealing the plated surface underneath. This can be done through various methods, such as peeling off tapes or dissolving the masking material with solvents.

Why is Part Masking Essential?

Part masking serves several crucial purposes in the plating process for diamond and CBN grinding wheels:

• Precision and Quality

  Part masking ensures that the plating is applied precisely to the intended areas, maintaining the tight tolerances, quality, and accuracy essential to precision grinding.

• Functionality and Performance

  By protecting specific features of the grinding wheel, such as arbor holes, flanges or threaded holes, from plating, part masking helps maintain their functionality and performance, ensuring they are dimensionally fit and operate correctly.

• Cost Efficiency

  Masking reduces the amount of plating material used, minimizing waste and lowering production costs. It also prevents the need for costly post-plating rework to remove unwanted plating.

• Customization

  Part masking, applied by hand, is customizable. This allows manufacturers to create tailored, complex products to meet specific customer requirements.

What It Takes to Be Good at Part Masking

Part masking is a specialized skill that requires attention to detail, precision, and an understanding of materials and processes. Here are some key attributes and considerations for those looking to excel in this field:

Attention to Detail

Successful metal part maskers must have a keen eye for detail. Precision is paramount in this process, as even the smallest imperfections or gaps in the masking material can lead to plating errors.

Material Knowledge

Familiarity with various masking materials and their properties is essential. Different materials may be required for specific applications, and understanding their characteristics can ensure the right choice is made.

Patience and Dexterity

The application of masking material can be a delicate and time-consuming task. Patience and manual dexterity are necessary to achieve consistent and high-quality results.

Problem-Solving Skills

Maskers may encounter challenges such as complex shapes or irregular surfaces that require creative problem-solving to ensure proper masking.

Advantages of Using Electroplated Diamond Grinding Wheels for Precision Grinding

With precision machining and grinding, the selection of tools plays a pivotal role in determining efficiency, profitability, and overall success. Among the many options available, electroplated diamond and CBN (cubic boron nitride) wheels rank high as indispensable assets for many manufacturers worldwide. These tools offer a unique combination of advantages that contribute significantly to superior performance and cost-effectiveness. In this article, we explore four key reasons why these tools are at the forefront of precision machining and grinding.

1. Consistent Distribution of Abrasive Particles

In precision grinding, the even distribution of abrasive particles is often critical for consistency. Electroplated diamond grinding wheels excel in this aspect, ensuring a uniform dispersion of abrasive particles across their entire surface. Unlike alternative bonding methods that may result in irregular spacing of abrasive grains, electroplated tools embed diamond particles evenly in a single layer. This uniformity translates to predictably consistent grinding or cutting performance. The same is true for electroplated cbn grinding wheels.

In practical terms, this means achieving precision and accuracy in your workpiece everytime, pass after pass. Whether working with robust metals, fragile ceramics, or intricate composites, manufacturers can place their trust in electroplated grinding tools to deliver a reliable and uniform cutting or grinding action.

2. Strong Bond Between Abrasive and Substrate

Another distinguishing factor that sets electroplated diamond tools apart is the robust bond formed between the abrasive particles and the tool's substrate. During the electroplating process, diamond grains become firmly embedded within a nickel or other metallic matrix, creating a tool of exceptional durability and resilience.

This sturdy bond ensures that the diamond particles remain securely attached to the tool's surface, even when subjected to high-speed or high-pressure operations. Consequently, these tools maintain their sharpness and cutting efficiency over an extended period, eliminating the need for dressing and maximizing time between replacements. This durability translates into significant cost savings by reducing downtime and material wastage.

3. Free Cutting Action Equates to Fast Cycle Times

Electroplated diamond tools offer a "free cutting action" that speeds up the grinding and cutting process significantly. Unlike conventional tools that may generate excess heat, clog, or wear unevenly, electroplated diamond tools efficiently remove material with minimal resistance.

This means reduced cycle times for manufacturers. Jobs that used to take longer can now be completed faster and with more precision. Whether shaping aerospace components or fine-tuning medical devices, electroplated diamond tools deliver both speed and accuracy. Fast cycle times translate to increased throughput, shorter lead times, and enhanced competitiveness in today's manufacturing landscape.

4. Maintenance and Reconditioning: The Strip and Replate Program

At Continental Diamond Tool (CDT), we go above and beyond to extend the lifespan of electroplated grinding wheels through our innovative Strip and Replate Program. This program harnesses strip technology to safely remove worn-down abrasives without compromising the wheel's core. We employ a chemical solution to delicately eliminate old abrasives, preserving the integrity of the wheel's substrate. After stripping, a new layer of abrasive material is expertly applied through electroplating.

The outcome? A rejuvenated electroplated grinding wheel that performs at its best. These reconditioned wheels undergo rebalancing to ensure optimal performance during extended runs. This program not only maximizes tool lifespan but also minimizes waste, translating into cost savings and reduced downtime.

High Flying Engineering Firm Says Fond Farewell to Founder Steve

(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.”
