-- About diamond cup grinding wheel

  • A diamond cup wheel is an abrasive tool with diamond bonded to the metal around its periphery. The name’s genesis arose from the shape of the tool due to a depression in the center. Furthermore, the style of the bonded diamond comes in different types. As the case may be, they are strictly for grinding, smoothening, or polishing. Other grinding wheels include the straight grinding wheel, grinding dish wheel, segmented wheel, etc.
  • Technically, the diamond cup wheel and diamond grinding wheel are the same,the cup wheel falls under the broad family of grinding wheels. The primary function of them is to prepare surfaces by grinding to reasonable smoothness. They efficiently handle dry grinding of concrete, granite, stone, marbles, and other hard materials. 
  • Also, for polishing, cleaning, and removing unwanted paints on materials, this tool best fits such a task. Unlike the regular abrasive wheels, the diamond cup wheel offers more force, and power to grind. 
  • A diamond cup wheel is as important as the diamond saw blades if you are a hobbyist, retailer, or professional. Regardless of how tough and hardened the surface you are handling can be, the diamond cup wheel always delivers.

7 Tips for Choosing the Right Diamond Cup Wheel

Grinding wheel for diamond processing

Choosing the right diamond cup wheel can cause a severe headache even to the most experienced supplier or end-user. It is because a diamond cup wheel, like every other diamond manufacturing equipment, is suitable for different applications.

However, regardless of what you intend to use this must-have equipment for, following the tips in this article can save you a lot of stress and prevent wasting your money on a tool that won’t give you the result we desire.

In this article, we will consider seven tips for choosing the right diamond cup wheel. Let’s dive in!
Why you need to master the tips for choosing the right diamond cup wheel

For anyone working in the diamond manufacturing industry such as distribution, supply, or end-user, a diamond cup wheel is a necessary equipment.

Together with diamond saw blades, this tool is handy for cutting hard surfaces such as marble, concrete, stone, and granite. Also, you can use this equipment in removing painting or coating from a surface. Besides, diamond cup wheels are useful in the simple clean up, polishing, and shaping for concrete surfaces.

When you get your tools selection right during the process of manufacturing diamonds, not only will you save time, it will also boost your productivity and save you time.

On the other hand, buying the wrong diamond cup as a supplier will hurt your brand if your customers are not achieving the result they desire. Meanwhile, it might not be your fault in selecting this tool, but as a distributor or supplier of diamond products, they expect you to know better.

Tips choosing a diamond cup wheel

These are some of the factors you must put into consideration when selecting diamond cup wheels. These include:

1.Select the right category of diamond cup wheel

The diamond cup wheel comes in variants due to different specifications. Your application will largely influence the category of diamond cup wheel to use. For instance, works involving heavy loads such as concrete and grinding stone will require a diamond wheel cup with a vast diamond segment. On the other hand, smaller diamond segments fit perfectly for lighter works, including glues, paints, epoxy, and all other surface coatings. Therefore, it’s imperative first to determine the nature of the task ahead.

Classification of Diamond Cup Wheel

Some of the characteristics to classify the diamond cup wheel include bond, grit, concentration, and hardness. All these hugely determine the type of diamond cup wheels to use. For instance, when choosing the cup wheel for a concrete surface, you should consider going for a soft bond while dealing with the hard ground. In contrast, hard bond works best with soft ground. It shows that knowing the exact diamond cup wheel suitable for your project is crucial. We will elucidate some of these classifications later.

2. Understand the Hardness of the Material Surfaces

Depending on the toughness of the surface, the diamond cup wheel generally exists in two phases. Phase 1 consists of coarse grinding. In this phase, there is a high propensity for the diamond to become blunt during this phase. It occurs because a diamond cup wheel quickly blunts out when dealing with hard surfaces. Thus, a soft diamond bond with high diamond highness is suitable for the first phase. Also, the diamond grit for this phase should be between 35 and 50. Conversely, the concentration of diamonds in the cup should be minimal.

Phase 2 involves fine grinding or polishing. It requires the use of a hard bond due to its superior precision. However, as diamond doesn’t disintegrate easily, a soft diamond will do the job succinctly. Grit between 80 to 120 is ideal at this phase, while the concentration needs to be set high. Regardless of your specifications, you can always talk to NCCutting Tools expert to have custom-made diamond cup wheels of any bonds, grits, and concentration.

3. Identify the right abrasive components

The diamond cup wheel has two significant parts. These include the abrasive grains that cut and the bond which hold the grain together and provide support during cutting operations. The combination of the grain, bond, and the spacing between the wheel form the structure. You must consider the percentage as well. The specific abrasive that a wheel uses mostly depends on its interaction with the work material.

A perfect abrasive can often self maintains itself through automatically sharpening that keeps the dullness minimal during use. The abrasive fracture works by establishing new cutting points when dulling set in. However, there is a unique feature for each abrasive type in terms of strength, hardness, resistance to impact, and fracture toughness.

Common types of Abrasive in Diamond Cup Wheel

Abrasives come in three primary forms. It includes aluminum oxide, zirconia alumina, and silicon carbide.

Aluminum oxide

Aluminum oxide remains the most popular of them all. Manufacturers prefer to use it as abrasive in alloy steel, carbon steel, annealed malleable iron, alloy steel, high-speed steel, and other similar metals. Aluminum oxide also comes in different variants, with each suitable for the specific grinding task. NC Cutting Tools manufactures all the time of abrasives. You can always get in touch with us for anyone you find the ideal for your project.

Zirconia Alumina

It’s less common, unlike aluminum oxide. However, the product comes from the combinations of the two to form sturdy and durable abrasive suitable for use in robust grinding applications. It includes cutting operations in several types of steels and their alloys. Like aluminum oxide, it comes in different varieties too.

Ceramic Aluminum Oxide

It’s the latest invention in the world of abrasives. It contains high-purity grain that follows the gel sintering process for its manufacturing. It’s suitable for precision grinding in materials that are very difficult to grind. Thus, you can use it in demanding applications that involve steel and sturdy alloys. It follows a combination of several percentages of other abrasives to derive high performance for intensive applications.

Silicon Carbide

This abrasive works well with less sturdy materials such as aluminum, soft bronze, gray iron, chilled iron, and other non-ferrous metals. You can also use it for rubber, brass as well as stone.

4. Check the grit size

Every diamond cup wheel comes with a number that that showcases its characteristics. It represents the size of the specific abrasive grans that the wheel carries. To determine the grit size, you have to count the number of openings per linear inch. You will find this in the final screen size. Thus, the higher the number, the smaller the openings for grit passage. Coarse grains have numbers such as 10, 16, and 24. Coarse grain indicates that the size of the material the tool removed is large. Grit wheels range between 70, 100 and 180, and useful in making fine grit wheels. Also, they are ideal for fine finishes, tiny contact areas, and useful for materials with high brittleness.

5. Know the different diamond cup wheel shapes

Although all diamond cup wheels may look like they are straight when you view the picture, they come in a wide range of shapes. Some have a recessed center that enables them to fit into machines spindle flange assembly. Others include cylinder and dish wheel that also have different shapes. Wheels that have cutting faces on their sides are suitable for grinding the teeth of cutting tools. Also, it’s perfect for surfaces that are hard to reach. Some mounted wheels also come in a cone or plug shapes. They are suitable for off-hand and grinding jobs that require high precision.

6. Go for the right bond

You need the proper bond for your wheel to run efficiently. Bonds are materials that hold abrasive grains in place to prevent them from falling apart and run effectively. Bonds, like abrasive grains, also wears away with frequent use. The primary bonds that are in use in diamond cup wheels are vitrified, and organic bond. Each has its unique strengths and weaknesses. For instance, vitrified bonds are both hard and brittle. Also, they offer resistance to acid, oil, water, and temperature.

Organic bonds exist in different forms, such as resinoid and rubber. Organic bonds are ideal for use in fabrication industries for diamonds and also for sharpening saws.

7. To customize or not?

It is a decision you must make. The internet offers a wide range of diamond cup wheels. While many of them live to their billings, unfortunately, most are well package junks that will not provide the result you desire. Instead, it’s advisable to go for a customized diamond cup wheel. Besides that, they offer the best value for money; you can freely customize the specifications according to your needs. Also, with a customized cup wheel, you will successfully eliminate guess works.
