What is the cause of the rough surface of the bearing

release time：2017/10/10 15:14:34

The surface roughness of bearing parts has standard and process requirements, but in the process of grinding and super-finishing, for various reasons, it often fails to meet the specified requirements.

The main reason why the bearing surface roughness is not up to the requirements

1.The grinding speed is too low, the feed speed is too fast, the feed amount is too large, and the no feed grinding time is too short 

2.The workpiece rotation speed is too high or the workpiece shaft and the grinding wheel shaft vibrates excessively;

3.The grinding wheel is too thick or too soft;

4.The dressing speed of the grinding wheel is too fast or the clearance of the dressing mechanism is too large;

5.The diamond of the dressing wheel is not sharp or poor in quality;

6.The quality of superfine oilstone is not good, and the installation position is not correct;

7.The quality of superfine kerosene does not meet the requirements;

8.Super fine time is too short.
