Abstract
Located for rotation in a machine base (1) is a work spindle (4) for the setting up of a workpiece (6). A grinding spindle (10) for setting up a grinding wheel (11) can be radially infed relative to the work spindle (4) and displaced in the plane at right angles to the infeed direction. A pick-up holder (22) with several measuring sensors (23, 24) is displaceable parallel to the axis (7) by means of an NC controlled spindle (16). With the apparatus described the workpiece (6) can be measured for mesh-aligning before grinding, as well as during grinding (e.g. for avoiding grinding burn), and after grinding (for final inspection). The process permits high productivity with short cycle times and few rejects.
