Method and device for grinding rotationally symmetrical bodies, in particular valves

摘要

A grinding device for valves (7) is provided with a chuck (6) which can pivot through 180 DEG inside a workpiece support (2) capable of being driven in rotation and which turns the valve, clamped centrically on the stem (11), from a first grinding position for dimensionally controlled grinding of the foot profile (8) into a second grinding position in which the sealing seat (23) is ground in accordance with the position of the grinding wheel (19) reached during finish-grinding of the foot profile. <IMAGE>
