Abstract
PURPOSE: To prevent works from transforming by cutting force by supporting a cutting part by several supporters in the trangential and the central direction to a grinding wheel which are equipped at the front end of a rest arm rocking round the main spindle of the wheel.
CONSTITUTION: As the cutting part a begins to be machined the front end of the rest arm 9 is made to rise by a rocking cylinder 10, supporters 12, 13 are in contact with the cutting part a and maintain the cutting reaction, but the cutting part a turns rotating on a circular orbit with rotation of the work A. With the turning of this cutting part a the front end also of the rest arm 9 follows the cutting part a round the main spindle 9a and moves vertically and therefore each of the supporters 12, 13 changes its supporting direction and receives its cutting reaction. At the same time the reaction given to the cutting part a changes according to locations of the cutting part a and this change is detected by the static pressure bearing 19 of a spindle 18, the load compensation cylinder 13a is controlled by a servo value 21, the supporting force of the supporter 13 is adjusted in proportion to change of the cutting reaction and high quality processing is achieved without giving any strain in the cutting part a.
