-- 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.

6 Tips for Selecting Concrete Grinding Wheel For Angle Grinder

A metal grinding wheel in action

A concrete grinding wheel for angle grinder is an indispensable tool for a mason that constantly deals with concrete. However, you should know that the angle grinder is only one part of the equation as you have to select the right concrete grinding wheel for angle grinder. Choosing the right grinding wheel is essential for the effective operation of your angle grinder. Consequently, we’ve taken the initiative to list some tips that you will find quite helpful when selecting the right grinding wheel for concrete.

1.Know the Abrasive Components: Grits or Grains?

Concrete grinding wheels, as well as other abrasive tools, comprise two major components – the abrasive grains that do the cutting and the bond that holds the grains in place while they cut. The percentages of grain and bond plus spacing in the wheel determine its structure. The nature of the abrasive also decides the kind of materials the wheel will be able to cut. Each abrasive type is distinct from its unique properties, such as – strength, toughness, hardness, and resistance to impact.

Aluminum oxide happens to be the very common abrasive manufacturers use in making grinding wheels. This abrasive works well for hard materials such as carbon steel, concrete, high-speed steel, alloy steel, wrought iron, and the like. Understand that there are different types of aluminum oxide abrasives; each of these abrasives comes with its designation. Plus, you can use them for different cutting and grinding operations.

Once you’ve established the grain texture, you should look at the grit size. The grit size is the size of individual abrasive grains in the wheel. Coarser grains allow for the rapid removal of material, plus you can use them when the finish isn’t important. Coarser grains come in small sizes – 10, 15, 25, while higher numbers such as – 70, 100, and 180 are fine-grit wheels. They are quite suitable for fine finishes.

2. Consider the bond strength.

If you want the abrasives on your concrete grinding wheel to cut efficiently, then the wheel must contain the proper bond. The bond is the material that holds the abrasives in place to enable them to cut more effectively. The bond should also wear alongside the abrasive grains, as it will expose sharper grains. Primarily, there are three types of bonds for concrete grinding wheels. Each of these bonds gives distinct characteristics to the grinding/cutting action of the wheel.

Before you select any bond for your concrete grinding wheel, you should consider factors like the operating speed of the wheel, the grinding operation, the right precision, and the material in question. Most grinding wheels come with vitrified bonds, which are very porous, strong, and rigid. The remove stock materials rapidly, and they grind to precise requirements. On the good side, they are resilient to water, oils, acid as well as harsh temperatures.

3. Determine the shape of the wheel

Concrete grinding wheels come in a variety of shapes. Most of us probably think that grinding wheels come in one straight shape, but it’s not true. As with other factors, you should also consider the shape of the wheel when selecting a concrete grinding wheel for angle grinder.

On some wheels, you will find the cutting face on the side of the wheel. These wheels usually take the names of their shapes, such as – cup wheels, cylinder wheels, and dish wheels. In some cases, manufacturers fuse-bond abrasive sections of a variety of shapes to form an intermittent continuous side grinding wheel. Wheels with cutting faces on both sides are best for grinding the teeth of grinding tools and other hard-to-reach surfaces. These considerations should come into play when you’re selecting a grinding wheel for concrete.

Wheel diameter is an important factor to consider when selecting a concrete grinding wheel for angle grinder. Angle grinders with bigger wheels tend to be more powerful.

4. Identify the grade of the grinding wheel.

You can find out the strength of a bond in the grade of the grinding wheel. You can tell if a bond is hard if the spans between each abrasive grains are resilient and hold the grains well against the grinding forces that try to loosen them. You can also tell a soft-grade bond if minimal force is all it takes to release the grains. The relative amount of bond in a wheel determines its hardness.

Hard grade wheels allow for longer wheel life, and for jobs that require high horsepower machines. You can also use them for jobs with narrow or small areas of contact. Soft-grade wheels are best for rapid stock removal, for jobs with a large or wide area of contact and materials such as carbides, steel, and concrete.

5. Determine the finish you’re looking to have

The amount of stock you’re looking to remove is also a critical consideration, as this plays a massive role in the finish. Coarser grits will do well rapid stock removal since they are capable of heavier cuts and greater penetration. However, if you’re looking to have a nice finish, then you’ll need a finer grit wheel for your grinding operations. You also need to pay critical attention to the horsepower of the angle grinder as a high RPM can exert a tremendous that may allow for the rapid removal of the material.

The finishing you’re looking to have should also influence your choice of wheel shape as this is crucial as well. In this regard, you should invest more in soft-grade wheels as they require minimal RPM to expose the abrasive grains. It allows you to regulate the horsepower.

6. Consider the wattage of your angle grinder.

The wattage is quite important as it will feed the grinding wheel with the power to cut or grind the material in question. Speed is also of immense essence here; you will need an angle grinder that can match your work speed, which is also congruent to having a high wattage tool.

If you’re looking to cut hard materials like concrete and the likes, then you should go for a material with high wattage, as this will also allow you to use your angle grinder for a long time.
