とを特徴とするローラ式レスト装置。 A pair of rest rollers, which are rotatably supported between the headstock and tailstock, sandwich the axis of the workpiece, and contact the outside diameter of the workpiece. A rest device rotatably supported around an axis by a support shaft includes a cylinder that moves the pair of rest rollers forward and backward with respect to the workpiece axis, an advancing end that forms a contact position between the rest roller and the workpiece, and a cylinder that moves the pair of rest rollers forward and backward with respect to the workpiece axis, and a forward end that forms a contact position between the rest roller and the workpiece. forward/backward position detection means for detecting the backward end of the rest roller that is in the carry-in/out position; a fluid supply device that supplies fluid to the cylinder to advance the rest roller; The present invention is characterized by comprising: a booster device that supplies a fixed amount of fluid at a higher pressure than the fluid to the cylinder when detected, and a rest roller regulating device that regulates the advance and retreat of the rest roller at the contact portion. Roller rest device.
