Abstract

PURPOSE:To obtain rapid and accurate location by estimating previously overrun of an oil hydraulic cylinder, which is to operate the locating member, and by giving speed-down command prior to a certain point and the stop command prior to the aim position. CONSTITUTION:Coarse movement of a table 1 is made by an oil hydraulic cylinder 2 and fine movement is made by rotation of a screw. Pulse motors 5, 6 perform opening and closing of a valve for supply of the cylinder with the working oil and rotary drive of the screw so that, when the table 1 has reached the point with No.1 specified value L1 before the aim position, the coarse movement pulse motor 5 is given speed-down command, and when the table 1 has traveled further and reached the point with No.2 specified value L2 before the aim position, the pulse motor 5 is given stop command. The table 1 is thus stopped first a little before the aim position and then sent further to the aim position accurately by rotation of the screw driven by the fine movement pulse motor 6.
