GERAET ZUM AUFNEHMEN DER POSITION EINER WERKZEUGMASCHINENSPINDEL.

摘要

The position of a machine tool spindle thermally displaced by the heat generated in the spindle bearing or the like is detected in the x and y directions, respectively, as a zero point by a single proximity switch (15) and the count values of x-axis and y-axis counters of an NC control panel are subjected to zero point calibration, whereby the resulting point is used as the origin of the coordinates. This enables machining of work with a high degree of accuracy at a high spindle speed where the spindle is subject to thermal displacement due to the heat generated in the spindle bearings or the like.
