摘要： A control panel 21 has a display screen 22. An operator turns a low-thrust pressing key 28 ON in the menu key group 26 displayed on the display screen 22. In this state, the operator turns an operating dial 32 of a manual pulse generator 31, thereby causing an encoder 34 to generate pulses. When the encoder 34 outputs a pulse signal as a command signal, and a servomotor 17 is driven in accordance with the command signal, the tailstock is advanced. With the distal end of a tailstock center contacting a center hole of the workpiece, the operator turns the operating dial 32, thereby finely adjusting the drive torque of the servomotor. Accordingly, the thrust of the tailstock center is finely adjusted, so that the tailstock center is pressed against the workpiece by a low thrust.
