Grinding wheel is made of abrasive and bonding agent made of the central circular through-hole consolidation abrasive. This is mostly used in conventional grinding wheel, carborundum grinding wheel, White Corundum Grinding Wheel, Green Silicon Carbide Grinding Wheel, Black Silicon Carbide Grinding Wheel etc. Through the abrasive particles from the surface of the wheel off the ease, you can determine the hardness of abrasive wheel. It is called Grade of Grinding Wheel, Used to indicate the hardness of the code, increasing from A to Z, the detailed Grinding Wheel Grades listed as below:

In general, the hardness of the soft wheel is more suitable:

1) Large feed coarse grinding.

2) large contact surface grinding occasions.

3) hard materials, such as high hardness tool steel and hard alloy.

4) poor thermal resistance of the work-piece, prevent surface burns.

Harder hardness of the wheel is more suitable:

1) small feed precision grinding.

2) extend wheel life.

3) the material is softer work-piece.

4) grinding the contact surface is small or narrow occasion.

Grinding wheel selection, pay attention to the appropriate hardness, if too hard, blunt abrasive particles do not fall off in time, will produce a lot of heat, burn the work-piece; too soft wheel, it will make abrasive off too fast and can not fully play its role.

The choice of Grinding Wheel Grades:

1. The harder the work-piece, the softer the wheel.

2. The larger contact surface of the grinding wheel and the work-piece, the softer the grinding wheel.

3. Grinding and shaping Grinding should choose a harder wheel, in order to maintain the necessary shape accuracy of the wheel.

4. Grinding wheel Grades selection and size of the relationship between the size: The larger the size of the wheel, to prevent the wheel was clogged debris, generally choose a softer wheel.

5. Work-piece material: grinding non-ferrous metals, rubber, resin and other soft materials, should be used softer wheel.

While the in supper-hard Abrasive Industry, CBN Grinding Wheel Grades and Diamond Grinding Wheel Grades, they are totally different from the conventional grinding wheel. There is exact no. to represent the grades of Grinding Wheels.
