Abstract

The present invention relates to a method and an apparatus for grinding button tool drilling heads (16), comprising the steps of moving a grinding spindle (24) along a conical enveloping surface and simultaneously turning the spindle (24) about its longitudinal axis (32). The characterising feature of the invention is that the rotation of the grinding spindle (24) is effected by the engagement of the grinding spindle (24) with a stationary face (31). <IMAGE>
