<p><P>PROBLEM TO BE SOLVED: To provide a machine tool capable of simplifying supply piping of pressure oil and shortening time required for changeover of a tool when a workpiece is changed. <P>SOLUTION: The machine tool 1 includes a plurality of hydraulic cylinders 31, 51 and 71 worked by the pressure oil, a plurality of positioning members 20, 40 and 60 for positioning the workpiece W on a tool base 4a by activation of the hydraulic cylinders 31, 51 and 71, and a plurality of manual valves 32, 52 and 72 switched over by external force and each controlling a positioned state of the workpiece W. The machine tool 1 further includes a main supply pipe 15 for coupling a hydraulic pump 11 with the tool base 4a and a plurality of branch pipes 16, 17 and 18 comprising the main supply pipe 15 branched at the tool base 4a so as to couple the main supply pipe 15 with the respective hydraulic cylinders 31, 51 and 71 and deliver the pressure oil to the respective hydraulic cylinders 31, 51 and 71. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
