Dressing device for centerless grinding machine and dressing method for centerless grinding machine

Abstract

A dressing device capable of effectively performing, in a centerless grinding machine, dressing to a grinding face of a grinding wheel and a rotary supporting face of a regulating wheel, performing relative positioning in axial direction of the grinding wheel and the regulating wheel after dressing, easily and accurately, and also reducing the equipment installation space. The dressing device includes a single dressing means for performing dressing to the grinding face of the grinding wheel and the rotary supporting face of the regulating wheel, this dressing structure including a rotary dresser having a profile fit for the grinding face of grinding wheel and the rotary supporting face of the regulating wheel. This makes it possible to perform dressing and truing of the grinding face and rotary supporting face accurately and at high precision regardless of the complexity or not of their profile, and any relative displacement in an axial direction between the grinding wheel and the regulating wheel are not produced in the course of dressing,. and the positioning in the axial direction of the grinding wheel and the regulating wheel after the dressing can be made easily and accurately.
