How to judge the service life of resin diamond grinding wheel

We all know that many things have their own service life, and resin diamond grinding wheel is no exception. Correct use can prolong its service life, on the contrary, it will make the grinding wheel wear faster. In fact, there is also a basis for judging the service life of the grinding wheel. We might as well follow Hua Yixin.

What is grinding wheel life? In fact, it refers to the grinding time between the two dressing of resin diamond grinding wheel; The service life of grinding wheel is usually judged visually according to the wear reflected in its work. These include:

1. During the grinding process, there is self-excited vibration or vibration marks on the part surface;

2. When the resin diamond grinding wheel works, the grinding noise becomes larger and larger;

3. There are grinding burns on the part surface, and the grinding force gradually increases or decreases;

4. The grinding accuracy of the grinding wheel decreases, but the surface roughness increases;

All these conditions are caused by thermal damage on the workpiece surface caused by high grinding temperature and the decrease of roughness and accuracy caused by self-excited vibration.
