For the selection of diamond grinding wheels, the selection of grinding wheels is usually based on these three factors: roughness, life, and grinding efficiency. The roughness is determined by the particle size of the abrasive, and the selection of the abrasive particle size of the grinding wheel can be determined according to the roughness; the hardness of the grinding wheel and the size of the organization can be determined according to the requirements of service life and grinding efficiency. The following summarizes ten effective methods for diamond grinding wheel selection.

1. Choose coarse particle size for rough grinding and fine particle size for fine grinding.

2. the sheet grinding wheel should choose rubber or resin binder.

3. The hardness of the grinding wheel should be higher during fine grinding and forming grinding.

4. When the particle size of the grinding wheel is fine, the hardness of the grinding wheel should be lower.

5. When forming grinding and precision grinding, a diamond grinding wheel with a tighter structure should be used.

6. when the workpiece grinding area is large, the grinding wheel with loose organization should be selected.

7. When grinding soft materials such as non-ferrous metals, a soft and loose grinding wheel should be selected to avoid blockage of the grinding wheel.

8. If the hardness of the workpiece material is high, a soft grinding wheel should be selected, and if the hardness of the workpiece material is low, a hard grinding wheel should be selected.

9. grinding steel and other ductile materials should choose corundum abrasives; grinding cast iron, hard alloys and other brittle materials should choose silicon carbide abrasives.

10. Soft grinding wheel should be selected if the grinding contact area is large. Therefore, the hardness of the grinding wheel for internal grinding and face grinding is lower than that for external grinding.

There are many selection methods for diamond grinding wheels, and there will be different processing according to different requirements. The ten methods summarized above hope to provide a reference for you to choose diamond grinding wheels.
