Superabrasive tools are top-notch in a variety of industries and manufacturing endeavors. When working with materials such as fiberglass, quartz, various composites, ceramics, carbides, and other materials, diamond tip saw blades get the job done better. For the tools needed in innovative space exploration or high quality stone work, tools such as a continuous rim diamond blade provide a smooth, even, and polished finish.

Utilize a saw blade supplier with a versatile, well-stocked inventory and quick turn-around time. Our customers receive their new diamond plated router, saw blade, or tip, quicker, so they can get started creating products, technology, and innovations that may very well change the world.

Versatility is incredibly important in this industry. For that reason, it's also best to go with diamond saw blade suppliers who offer diamond blades, saws, and other tools that are capable of working with wet and dry materials. When working with marble, granite, concrete, ceramic tiles, and similar materials, the ability to work wet increases accuracy. When paired with a continuous saw, it significantly decreases the risk of chipping or mistakes, leading to flawless, polished work, whatever the need.

Creating statuary, granite or marble memorials, manufacturing tools and electronics used in space, and building tools for the medical field all require spotless, perfect work. The tools make all the difference, which is why it's essential to choose a manufacturer who guarantees quality pieces with many uses.

Bring the best to your customers. Rather than a large, jam-packed company which believes in quantity over quality, choose a smaller, more well-rounded supplier that responds with all the capabilities of a larger company. Whether you distribute to clients or companies that specialize in working with tiles, ceramic, fiberglass, or quartz, make sure that they'll have the best tools with the best reputation.

What Feed & Speed Do I Run the Wheel?

High-speed grinding wheels, like the CBN grinding wheel and diamond wheel can increase a manufacturer’s production rates, improve quality and reduce costs.

cdt-diamond-grinding-wheels-and-tools.jpg

High-speed grinding wheels can increase a manufacturer’s production rates, improve product quality, and reduce production costs. Two of the most popular superabrasive products used for these purposes include the CBN grinding wheel and the diamond wheel.

CBN wheels are made with synthesized crystalline material produced in a similar way used for growing manmade diamonds. This is done with high-pressure, high-temperature techniques, so CBN wheels are similar to diamond wheels in that they are resistant to wear and noted for strength.

Abrasive grains for CBN wheels are improving each year leading to more controlled strength and shapes that were once challenges in this industry. Whether a customer chooses to use a CBN wheel or a diamond wheel, it’s important to note which elements are significant in achieving the desired result.

The wheel diameter plays an important role, since the smaller the wheel the easier it is to use and, generally, the less expensive it is. Small wheels are also easier to handle and balance. Larger wheels, however, are more suited to faster operating speeds.

All grinding wheels have a hub that has to be designed with proper mounting techniques in order for it to operate at the highest speeds. This means having the wheel mounted to a spindle that keeps it from shifting even as centrifugal force pushes the wheel into greater speeds. Any type of imbalance will affect the wheel’s stability and could result in dangerous slippage. Experienced CBN and diamond wheel suppliers will have worked out any balance issues and develop a quality superabrasive that will always be balanced and work at high rates of speed.

Coolant is also important with diamond cutting blades and CBN wheels since it keeps the wheels from overheating. Coolant also provides adequate lubrication and flushes out any particles and chips that could interfere with the wheel’s performance. Dressing is another important aspect, which is accomplished with rotary diamond technology.

Whether your needs deal with applications in the aerospace, ceramics, automotive, oil, electronics, or medical industries, it’s important to find a superabrasives supplier that has knowledgeable customer service and skilled experts that provide custom-made cutting and grinding products. Continental Diamond Tool is a leading supplier that has based its business on blending customer relationship with product performance. They boast not only superior superabrasive tooling, but offer some of the industry’s best delivery times, super responsive tech support, and all the latest bond technology. The unsurpassed quality and professionalism of this customer manufacturer makes ordering superabrasives easier than ever.

How do I dress my grinding wheel?

Diamond dressing tools are essential to keep grinding wheels true and free from particle buildup. This enhances grain exposure and abrades away some bond.

In the manufacturing industry, you know you often need one type of tool to maintain the maximum efficiency and life of other types of tools. Diamond dressing tools are among those essential assisting tools that keep grinding wheels true and free from buildup of particles. This dressing procedure keeps grinding tools, drill bits, chisels, and other tools with points or edges honed to their required sharpness.

VALUE OF DRESSING WHEELS

Using the appropriate diamond dressers or other diamond products on these abrasive wheels performs three important functions: (1) trues or re-balances the wheel to a concentric shape; (2) dislodges buildup of abrasive particles and bits of metal, exposing new abrasive surfaces of the wheel for more accurate grinding; and (3) cleans the wheel, renewing its edge and revealing sharper abrasive and fresh grains.

STEPS TO DRESS A GRINDING WHEEL

Here are the steps to take to effectively and properly dress a grinding wheel.

Step 1

Determine the proper dressing tool for the wheel. Make sure the grit of the dressing tool is finer by one or two sizes than the abrasive surface of the grinding wheel. Also make sure you choose the appropriate shape of dressing tool to coincide with your grinding wheel.

Step 2

Turn your grinding machine's coolant pump off (if it has one).

Step 3

Turn on your grinding machine and allow it to operate until it reaches its full RPM; you might choose to turn off your spindle motor, or keep it running, based on your personal preference or experience. Excessive need for truing might dictate keeping the motor on, rather than turning it on and off.

Step 4

Using light to medium pressure, apply the dressing tool to your wheel's abrasive section; continue applying pressure just until the wheel stops rotating.

Step 5

Repeat Step 4 until the dressing tool until the grinding wheel feels as if it is pulling the dressing tool away from you.

Step 6

Repeat Steps 4 and 5 as many times as necessary (four to five times, typically), depending on your grinding wheel's surface condition.

IMPORTANT ADDITIONAL TIPS

  • Ensure the tool rest is the appropriate distance from the grinding wheel (typically 1/16th of an inch) to prevent damage to the tool or injury to yourself.

  • Always wear safety glasses to protect your eyes from flying particles.

  • Avoid wearing loose-fitting clothing, such as long sleeves, and pull back long hair, when working near a spinning grinding wheel.

Which Dressing Tool is Right for You?

Use our dressing tools to ensure that your diamond grinding wheel will perform at maximum efficiency, trouble-free, and enjoy a long, sustainable life.

A diamond grinding wheel dresser is a vital tool in the proper care and maintenance of any grinding wheel. Regular maintenance ensures that your diamond grinding wheel will perform at maximum efficiency, trouble-free, and enjoy a long, sustainable life.

When selecting any dressing tool, including a diamond wheel dressing stick, it’s important to choose the tool that is the proper shape, size, and quality for the grinding wheel. If you don’t know which tool will work best with your application, discuss it with a supplier’s knowledgeable customer service department to determine exactly what you need.

Dressing the wheel will knock off any abrasive particles from the wheel’s surface. This ensures that it’s balanced and concentric, which minimizes any vibration it may get from having too much buildup on the surface. These particles, if left on the surface, have the potential to cover up surface abrasives, making them dull and ineffective. Exposing them by removing particles is essentially a sharpening process, since the fresh abrasive grains are each cutting tools in their own right.

A diamond grinding wheel dresser serves another important function, and that is to clean the grinding wheel. Choosing a dresser or grinding wheel dressing stick that is softer than the grinding wheel will not dislodge any abrasive particles, and can result in a loaded wheel. This is why selecting the proper dressing tools is crucial to a successful grinding wheel dressing.

There are also different types of dressers to consider. Star dressers feature long handles and serrated discs. Diamond dressers are generally preferred because of their superior strength. They also have shorter handles and are great for both dressing and truing. They are also available in single point and multi-set clusters to blade-specific type, and a reputable supplier will be able to determine which design to use based on your project. For example, a single point tool is easy to use and encourages a more pronounced rotation and higher frequency, delivering precise results.

Other benefits of a diamond grinding wheel dresser include a fast dressing of even the most complex wheels, a constant operation that boasts high-precision, and optimal dresser versatility. This type of dresser tool also means a decreased dressing cost per project, making it a cost-effective solution to all of your dressing needs.

How do Superabrasives compare to conventional abrasives?

Superabrasive wheels do not wear away like conventional wheels, therefore your shop and the air you breathe is much cleaner.

Superabrasives 101

download (7).jpg

If you’re in the market for superabrasives, it’s important to be familiar with common terms and product types that can help you discover which superabrasive is best for your needs. The metal bond grinding wheel is one of the most commonly used wheels, and the name denotes the metal bonding material that is most often used with a variety of grinding wheel types.

Using metal fillers, grinding wheels suppliers will manufacture the metal grinding wheel to specification. Metal bond is available with cubic boron nitride (CBN) and diamond wheels, and are generally used with coolant to prolong the wheel’s lifespan.

There are several advantages to using metal bond wheels, not least of which is its extended life. A metal bond ensures that the wheel has a fast stock removal. It also leads to a reduction in the dressing frequency and boasts more advanced form holding capabilities. Metal bonds are also extremely strong, so they are typically used in internal, form, glass, ceramic, tool cutting, and creep-feed applications.

A grinding wheel dresser, often referred to simply as a wheel dresser or grinding dresser, is an essential tool that dresses the grinding wheel surface. Dressing a wheel knocks any abrasive particles from the surface in order to make the grinding wheel concentric. This means less vibration and an improved finish. The grinding dresser is also important when cleaning the metal bond grinding wheel. One of the main benefits of using a metal bond grinding wheel is that it requires dressing less frequently than other wheel types.

Metal bond even goes beyond grinding wheels, since diamond core drills, solid diamond drills, and disintegrating core drills can all be manufactured using metal bond. Metal bond is primarily used in wet grinding. It can work well on glass, silicon, semi-conductors, refractories, and ceramics. Many industries choose to use metal bond tools because they are low maintenance but offer high productivity, making them ideal for maximum yield endeavors. They are also available in a range of tools, from the more aggressive CNC grinding down to light polishing.

When searching for grinding wheels suppliers, go with a company experienced in custom manufacturing with a wide range of superabrasives, including metal bond. A reputable company will tailor every order to each individual customer’s needs and offer a knowledgeable customer service that can help you determine the type of tools and products you need. Going with an experienced superabrasives provider will result in unmatched quality and a pleasant buying experience.

What bond is best for my application?

With superabrasives, several variables are considered to determine the correct bond for the application, such as material, hardness, grit and many others.

 

Types of CBN Grinding Wheels

download (8).jpg

CBN stands for cubic boron nitride. This is a type of synthetic compound as it, like all boron nitride compounds, is not found anywhere in nature. The structure of this compound is a symmetrical structure not unlike a diamond. It is extremely hard, stable under heat and has a high resistance to other chemicals. In fact, cubic boron nitride is the second hardest material, after a diamond. These properties make CBN extremely useful for industrial use. Learn more about how it can be used as an abrasive or cutting tool--particular as a grinding wheel--and perhaps you’ll discover how it could be utilized in your workplace too.

During the grinding process, you have a few options when it comes to what material to use. You should ask yourself the following questions to make your decision:

In many cases, you may decide that utilizing CBN material just makes sense. CBN grinding wheels are extremely hard and ideal for many jobs. Very little pressure is required, meaning that there is less heat and nearly no sparks generated. This is a big change versus using a grinding wheel that is not as hard. Additionally, these wheels are reliable and long-lasting, unlike standard abrasives, the wheel face remains straight, without grooves. The durability and low need for maintenance means that CBN grinding wheels are less-costly to operate than many other products too.

Because cubic boron nitride cutting tools are so hard and durable, they are ideal for use for a number of tasks such as metal grinding and tool sharpening. Plated tools, like the CBN wheels from CDT, consist of a single layer of CBN exposed from the bond instead of imbedded--like with resin and metal bonds. This also helps the wheel to hold its form and remain durable over the long haul. This will save you time and money and help provide optimal results.

When it comes to coated abrasives like CBN grinding wheels and abrasive technology in general, Continental Diamond Tools is your number one resource. We offer a number of options to meet or exceed your needs--no matter what your application. Additionally, we are experts in the plated abrasives industry. Whether you know exactly what you want and are ready to order, or you want to just talk to a professional about what options are available, call or contact us today and let us help you find the product that will work best for you.

What are the benefits of plated vs. bonded?

Our plated products consist of a single layer of Diamond or Cubic Boron Nitride (CBN) which offers the ability for strip and re-plate.

Grinding Wheels 101

A grinding wheel performs a range of abrasive machining operations in industries such as aerospace and petroleum. It can be made by pressing a matrix of coarse particles together into a circular shape, or by coating a solid material with the abrasive compound. The specific materials and shape of a grinding wheel depend on the application, although its manufacture is generally a precise process. Common types of grinding wheels include plated wheels, wheels that use resin to bond the abrasive compound to the wheel and those that use metal bonds.

Plated

download (7).jpg

A plated grinding wheel has a single layer of abrasive material that’s exposed to the surface, instead of embedding the material within a bonding compound. The abrasive material for this type of grinding wheel is typically cubic boron nitride (CBN) or diamond, which are extremely hard substances. Diamond plated wheels hold their form longer than bonded wheels, and they also form a more aggressive bond.

Plating provides diamond tool manufacturers with the ability to strip the abrasive material from the core product and re-plate it with a new abrasive layer. This advantage results in a plated diamond wheel that’s in “like new” condition, which extends the life of the initial investment.

Resin Bonds

resinbond.jpg

The resins that bond abrasives to grinding wheels are typically phenolic resins, meaning that they are made by reacting phenol. The resin also contains filler materials such as copper and an abrasive material like diamond or CBN. A hot press compresses this mixture into the desired form, which is then cured and machined to a precise shape.

Resin-bonded grinding wheels are highly efficient, allowing them to complete their tasks quickly. These grinding wheels are capable of prolonged use, due to their ability to sharpen themselves and maintain low temperatures during operation. Grinding wheels that use resin bonds are also easy to dress and less prone to overloading. Common applications for these wheels include grinding electrical carbon products such as carbide alloys, ceramics, ferrite and semi-conductors.

Metal Bonds

metalbond.jpg

The metal bonds used by grinding wheels are typically made by sintering powdered metals along with filler materials, and adding an abrasive such as CBN or diamond. These bonds are very strong, providing a grinding wheel that holds its shape well. The durability of metal bonds also means that these grinding wheels require dressing less frequently.

Metal bond abrasive tools offer maximum productivity, and are suitable for a range of applications, from light polishing to aggressive grinding. They’re most often used in wet grinding, but they can also grind dry surfaces such as ceramics, glass, quartz and silicon. Metal-bonded grinding wheels can be used for cutting tools and forms such as refractories. They're also suitable for creep-feed applications.

The Mars Rover Has Diamond Plated Wheels

CDT's custom-made diamond wheels prove to be groundbreaking on exploration to Mars.

download (9).jpg

When NASA launched the first Mars rovers in 2004, one of their tasks was to examine what was beneath the surface of the planet. Rock formations and soil samples would show us more about the planet's composition. One question was whether there had ever been water on Mars, one of the requirements to support life. To learn about the planet's history, it was necessary to dig into the soil and grind away rock, a task that required diamond plated wheels.

As a leader among diamond tool manufacturers, Continental Diamond Tool embraced the challenge of creating a custom grinding wheels that could be used to explore beneath the planet's surface. Our diamond wheel tool was affixed to the end of the Rock Abrasion Tool (RAT) created by Honeybee Robotics for the rovers Spirit and Opportunity.

Working for NASA contractor, Honeybee Robotics Ltd., CDT helped to design and develop several   for testing then waited in anticipation for Honeybee engineers to choose the suitable flight model.  The custom-made grinding wheel was then attached to the working end of the Rock Abrasion Tool (RAT), which was designed and operated by Honebyee Robotics Ltd.  

CDT created a soft resin bond formulation to work with the low down force the RAT's robotic arm. Our custom plated diamond wheel grinding tool successfully dug a hole in the rocky surface that was 5 centimeters wide and 5 millimeters deep. The RAT mounted to the end of the robotic arm located on each Rover (named Spirit and Opportunity) which was responsible for investigation the martian surface and arriving at the research location.

The rovers sent back both panoramic and microscopic images of their discoveries. All rocks found on Mars were covered in dust and mineral rinds; some could be brushed off, but another type needed to be ground off with tools on the RAT. Analysis of the rock and soil on Mars yielded many excited revelations. In a rock known as Humphrey, formations suggested that minerals had been carried through pores in the rock by water. Another flaky rock formation, Mimi, may have been cemented into its layers through compression, which also often involves water. Rocks in the Gusev crater seem to be a type of volcanic basalt. They contain the minerals magnetite, olivine, pyroxene, and plagioclase. There are high levels of nickel, which likely came from meteors. Rocks on the plain show signs of being affected by small amounts of water.

In 2009, Sprit became stuck in soft soil over a slick bed of iron sulfate and was unable to be moved. NASA repurposed the stranded rover as a stationary research platform, monitoring for planetary wobbles that would indicate whether Mars has a liquid core. The rover's last communication came in on March 22, 2010. The Opportunity rover remains active on Mars, nearly ten years after the planned ending of its mission of 90 Martian days. Its task now is to detect signs of life in the history of the red planet. The Mars rovers stand as a testament to what is possible when science and industry work together to increase human knowledge.
