Claims

[Claims for Utility Model Registration] In a workpiece support device for a grinding machine, the workpiece is supported by an upper roll, a lower roll, and a shoe and the workpiece is ground, the upper roll being rotated. a rotational drive source for driving the lower roll and selectively rotationally driving the lower roll via a clutch; a pressing device for adjusting the pressing force of the upper roll against the workpiece; and a rotation speed of the lower roll. a rotation speed detecting means for detecting the rotation speed; and disconnecting the clutch after starting the workpiece, and increasing the pressing force of the upper roll as the rotation speed of the lower roll increases after the clutch is disconnected. A workpiece support device for a grinding machine, comprising: a control circuit for controlling the grinding machine;
