Patent DE-2927650-A1 (DE)
Inventor: WAELTI WERNER
IPC: B24B5/04
Filed: 1979-07-09
Abstract: When cylindrical grinding a cylindrical part (9) on a grinding machine, the dimensional accuracy of the finished part is essentially dependent on the position of the axis (10) of rotation of the cylindrical part (9) relative to the axis (11) of rotation of the grinding device (5) corresponding precisely to a desired value. By measuring the diameter of the end regions of the cylindrical part (9) by means of a measuring device (6) with measuring probes (13; 14) and a corresponding pivoting movement of the axis (10) of rotation of the cylindrical part (9) before the final cylindrical-grinding procedure, high-precision cylindrical grinding of the cylindrical part (9) is possible. Pivoting the axis (10) of rotation is achieved by displacing the spindle tip (2) out of the original axis (10) of rotation. <IMAGE>
