Abstract

PURPOSE:To prevent the reduction of rotary accuracy due to the deflection of the main shaft, and the reduction of processing accuracy, by means of controlling the supercharged quantity of a bearing according as the increasing or decreasing of a load exerted upon the bearing of the main shaft, and of controlling the tension quantity of a transmission belt according as the increasing or decreasing of a driving torque of the main shaft. CONSTITUTION:In a case when the driving torque is a little by the light processing and the supercharge of a bearing may also be a little, the tension of a transmission belt 23 by a tension roller 43 is regulated for light cutting by a knob 47 via a spring 45, and the supercharge against to the bearing is regulated for light quantity by a supercharge regulating nut. On the other hand, in a case of a heavy processing, said regulation is regulated to ''strong'' direction, and the reduction of processing accuracy is prevented.
