Rotary diamond dresser for dressing wheel

Bearing raceway grinding methods are divided into swing method, cut method and forming method. Among them, the cutting method is the most common. The method used is to dress the grinding wheel into the required raceway shape and then directly process the raceway shape by the cutting grinding wheel. The surface topography of the grinding wheel will be reflected on the machining surface. Therefore, the dressing accuracy of grinding wheel working surface is the key to affect the machining quality of bearing raceway.

Diamond grinding wheel for dressing

In the grinding process, the edges and corners of the grinding wheel are gradually rounded and blunt under the action of friction and extrusion, or when grinding ductile materials, grinding chips are embedded in the pores of the grinding wheel surface, so that the surface of the grinding wheel is blocked, and finally the grinding wheel loses its cutting ability. Therefore, we need to dress the grinding wheel. The common dressing methods are as follows.
