MASS CENTERING MACHINE

摘要

A mass centering machine, comprising a measuring station and a machining station separated from each other, the machining station further comprising a holding device capable of developing a high holding force so that a work is not rotated during the machining of the work and capable of being reduced in size and weight, wherein clamp claws (224) coming in point-contact with the work (W) or in line-contact axially with the work (W) are provided on the holding device of the machining station, whereby, even if the work (W) is forced to rotate, the clamp claws (224) bite into the work (W) to surely hold the work (W) with a small clamping force so that the work (W) is not rotated.
