Abstract
The invention applies to a process and rotary point crush truer device to dress grinding wheels with profiled working surfaces with a rotary truer where the grinding wheel and rotary truer to whose surfaces are applied a material of greater hardness than the grinding wheel to be dressed, allowing the grinding wheel and rotary truer to run with the same circumferential speed and, at the same time, the grinding wheel and the rotary point crush truer device to press together under high pressure. It is the task of the invention to create a possibility of a simple means to avoid the abrasion in the above mentioned process of crush dressing with different surface speeds between the grinding wheel and the rotary truer, and thus to achieve long tool life of the dressing tool. The invention holds that a circular plane hard metal wheel is used as rotary truer to whose face diamond material is evenly applied, that the grinding wheel and rotary truer is placed in relation to each other so that between the grinding wheel and rotary truer only a near point contact occurs and that the pressing pressure between the grinding wheel and rotary truer is so high that the bond posts fracture between the…
