What are the ways to prevent grinding burns on rolling bearing sleeves?

1. Select a suitable grinding wheel: Choose a grinding wheel with moderate hardness and moderate structure number to ensure grinding efficiency and bearing accuracy while reducing friction heat between the grinding wheel and the workpiece.

2. Control the grinding thickness: Reducing the grinding thickness can reduce metal plastic deformation and internal friction, thereby reducing the generation of friction heat.

3. Increase the workpiece speed: Increasing the workpiece speed can shorten the time for the grinding surface of the workpiece to pass through the grinding area and reduce the accumulation of friction heat.

4. Control the feed rate: For materials with high grinding strength, high hardness and poor thermal conductivity, a smaller feed rate should be used to improve grinding efficiency and avoid burns.

5. Adequate cooling: Using sufficient cutting fluid during the grinding process can effectively reduce the grinding temperature and reduce the possibility of burns.

6. Standardized operation: Strictly abide by the operating procedures to avoid grinding burns caused by improper operation.

Please note that in actual operation, parameters and operating methods should be adjusted according to specific conditions to achieve the best results.
