Abstract
A rest apparatus for supporting a cylindrical portion of a workpiece to be machined. A pilot shaft is supported at the opposite ends thereof by a support head and provided with a piston portion to form a hydraulic cylinder with a cylinder bore of a rest housing so as to move the rest housing toward and away from the workpiece. The axis of the pilot shaft passes through or slightly above the axis of the workpiece. Rotation of the rest housing about the pilot shaft is prevented. A pair of rest shafts are slidably but nonrotatably received in the rest housing for horizontally and vertically supporting the workpiece by a pair of rest shoes. Feed apparatus is operatively connected to the pair of rest shafts to feed the pair of rest shoes toward the center of the workpiece.
