Traditional indexing rotary table to maneuver, but only some of the provisions of sub-degree angle, it is difficult to meet some special requirements indexing workpieces. Control technology for the use of this topic, stepper motor control technology to sub-degree rotary table for the NC transformation, design of an automatic indexing rotary table. It MCU to control the core, by controlling the pulse distributor to send pulses to the stepper motor, stepper motor drives the worm gear drive to achieve sub-degree rotation of the workpiece, as opposed to traditional mechanical dividing head, easy operation, high precision indexing.
