THERMAL DEFORMATION CORRECTION METHOD FOR BALL SCREW OF MACHINING CENTERS

摘要

The present invention, for a thermal deformation correction method of a ball screw which occurs during the operation of a machining center, relates to a thermal deformation correction method of a ball screw which is not affected by operation environment of the machining center and an irregular operation time. The present invention can correct thermal deformation amount of the ball screw to suit some operating environments of some because an operator actually measures the thermal deformation amount of an X, Y, and Z axes in the operating environment of the machining center by combining a correction machine formed to be inclined by 45 degrees simply to a tool length correction device only capable of correcting the Z axis of the machining center.
