1.

Compensating Chuck-SFC has been improved from compensating structure of plane sliding of the existing chuck to the sliding structure of the spherical surface, which ensures the outstanding accuracy, and long life.

2.

This chuck equally excise its force to each jaw, and the jaw moves respectively to clamp the workpiece. Therefore, the clamping is possible based on the centers of the workpiece to be processed. Especially in case of forged and casted workpiece with irregular diameters, it is possible to get high accuracy of concentricity based on centers.
