The machine adopts column feed, can achieve automatic working cycle of three cuts. Adopt the parameter of cutting rationally can improve production and the precision effectively. A frequency conversion is adopted for the primary motion, circular motion, and a servo is adopted for the radial feed. The three motions vary automatically by computer. In the three cycles, you can preset different rotary feed of stroke of primary motion, realize the cutting for same power, and show various kinds of cutting parameters in the course of processing at the same time.
