PURPOSE: To enable a structure to be simplified an made compact by providing a positioning cylinder, a clutch cylinder, a clamp cylinder and the like for respective operations in order to let compressed fluid flow through in series in the order of operations and to operate the cylinders.
CONSTITUTION: A turret table is indexed in the machining position, and pressure oil is supplied to a cylinder chamber 112a for positioning through a switching valve 202 and an oil passage 211 in order to engage a positioning pin 113 with a missing part 111 to be located. A port 213 is connected to a cylinder chamber 76a for supplying cutting oil by the movement of a piston part 113a, where cutting oil is supplied. Then, similarly, a connecting pin 155 is drawn out of a connecting hole 107, a turret table is fixed by a piston 127, and a clutch rod is connected to an input axis by a cylinder 52 for operating a clutch so as to transmit power of a motor to a tool for machining. The reversed operation is carried out by switching the port 206 of a switching valve 202 with a port 270 after finishing the above machining.
