PURPOSE:To attain miniaturization and low cost, by using one set of constant position stop circuit in common with the control of constant position stopping of main spindle and the deduction of the rotating position of a blade stand. CONSTITUTION:In positioning the main spindle 10, switches SW1-SW3 are switched to the spindle position (shown in figure) and a reference position data is inputted to the constant position stopping circuit 104. Then, the circuit 104 positions the main spindle 10 to the commanded position in cooperation with a servo unit 101. Further, in positioning the blade stand 15 and selecting a prescribed tool, the switches SW1-SW3 are selected to the blade stand side and the tool position data is inputted to the stop circuit 104. Thus, the circuit 104 positions the blade stand 15 in cooperation with the unit 101 to select a commanded tool. Since one constant position stop circuit is used in common, miniaturization and low cost are attained. |
