Abstract

PURPOSE: To move a tool at high speed by providing each motor for rotating a ball screw bearing and a spline bearing, and providing a control device for driving the motor for the spline bearing to the direction reverse to the rotation direction of the motor for the ball screw bearing at the time of driving the motor for the ball screw bearing.
CONSTITUTION: A motor 6 for a spline bearing is rotated reverse to the rotation direction of a motor 4 for a ball screw bearing by a control device 15. A ball screw bearing 3 and a ball spline shaft 8 are thereby rotated relatively, and the ball screw bearing 3 is rotated at the speed that the speed of the ball spline shaft 8 is added. The ball spline shaft 8 and a working tool 7 can be moved to a predetermined position at high speed without increasing the rotation of the motor 4 for the ball screw bearing.
