Abstract
This machine is for grinding cylindrical portions (pin portion) of a compressor shaft etc. used in an air conditioner whose pin center is eccentric relative to a rotational center of the shaft, by following a feed motion of a wheel head to a rotation of the shaft. In order to improve both productivity and machining accuracy, it is required not only to rotate the shaft at a high speed but also to accurately move the wheel head. In this machine, the high speed and high accurate grinding has been realized by using a linear motor as an actuator of the wheel head. The machine construction, principle of pin portion profile grinding and machining result are explained.
