As the main components of hydraulic cylinders, mining monolithic pillars, hydraulic supports, gun barrels and other products, the hydraulic cylinder barrel directly affects the life and reliability of the entire product. The processing requirements are high, the inner surface and the coaxiality , Strict wear resistance, the basic feature is deep hole processing.
