USES and features Piston ring DX06-5 type nc grinding machine tool. The machine is our factory according to the finished product before, cone ring, ring barrel surface plating need smooth surface, the adjacent edge chamfer place clean, and grinding quality directly affects the quality of plating surface. Domestic existing piston ring processing equipment, most flexible polishing, and the clamping the whole cylinder ring center deviation, namely core rod bending of directly affect the surface quality of the piston ring. The biggest characteristic of the machine tool is a flexible device surface of piston rings pressure constant, wide adaptability, large and small ring universal process, feeding speed and movement speed of servo motor and CNC control respectively. The operation is simple, safe and reliable, in the middle of the fuselage set one on one off two buttons finishing in the electrical box (manual) processing fashion has a protective cover.
