Study on Dressing of Grinding Wheel (2nd Report)

A dressing technique with a diamond cup wheel as a dresser is introduced for higher performance of grinding wheel. In the technique, the rotating diamond cup wheel is fed parallel to the wheel axis. Grinding performance is experimentally investigated under various setting conditions of the dresser, dressing conditions and grinding coditions, analyzing size generation process, grinding force, surface finish, wheel wear and so on. Sharper cutting edges are generated on the acting wheel face in the technique, while the number of cutting edges is slightly fewer than that in conventional method with a single point diamond dresser. Grinding force is therefore smaller while surface finish is rougher and wheel wear is larger as compared with coventional one. Furthermore, the grinding results are hardly affected by dresser wear in the technique, while those are significantly affected in conventional one.
