The main drive adopts the crank mechanism, which is realized by the servo motor through deceleration. The X and Y direction feed realizes the stepless speed regulation function by the servo control. The X direction ball screw is directly connected with the motor, and the Y direction ball screw and the motor are transmitted through the synchronous belt. According to the needs of users can be configured with NC dividing head or NC turntable, the machine tool function is particularly powerful, can process different angle direction keyway.
