Peripheral grinding method for rotary workpiece e.g. crank-shaft crank pins

摘要

The peripheral grinding method has a rotary grinding disc (3) brought into contact with the rotary workpiece by transverse displacement along an axis (x) at a given angle to its rotation axis, with indexing along the displacement axis for each rotation of the workpiece. The indexing displacement of the grinding disc is controlled in dependence in the actual material thickness (Ai) removed from the periphery of the workpiece during the previous rotation, provided by a workpiece diameter measuring device (16,17,18).
