In this design, I use a step-by-step the electrical machinery to control the corner of rotary table. Under the control of monolithic integrated circuit, the number of pulse of the step-by-step electrical machinery each second can be sent out to decide the rotary table’s indexing angle, making the gear shaper to become the random indexing processing in the true sense .And then, the gear processing which is mentioned willfully might be realized. The rotary table designed in this topic is controled by the monolithic integrated circuit to control the rotational speed of step-by-step electrical machinery, the step-by-step electrical machinery send out the power firstly, through the gear drive and the worm gear worm drive, then the power is transmisted to worm gear , and worm gear-rotating makes the main axle rotate the same time, and then,it comes to be realized that the work piece clamped with main axle come to rotate.In my opinion，this design of the rotary table is practical, simple, reliable, and the efficiency is high.
