[Summary]As the main part of grinding wheel grinding, the grinding wheel disc is very large in total loss during work.

After the grinding wheel has been working for a period of time, its working surface will be passivated. If it is used continuously, the friction between the grinding wheel and the surface of the workpiece will be intensified, thereby affecting the surface quality of the workpiece. Therefore, you should choose an appropriate time to dress the grinding wheel in time.

There are three forms of blunt grinding of grinding wheels, namely, blunt grinding of abrasive grains, distortion of the shape of the grinding wheel, and blockage of the grinding wheel.

Dressing method of grinding wheel grinding disc 1. Diamond is a commonly used dressing tool. It has extremely high hardness and its sharp angle is 70°-80°. During dressing, the abrasive grains will break when they hit the hard tip of the diamond. As a new micro-tolerance, due to the small contact area between the diamond and the polishing sheet, the elastic deformation caused is also small, so that a finely trimmed surface can be obtained.
