. v ial milling machine, hydraulic design special milling machine is based on needs of work, based on hydraulic transmission, match with a few special parts of a machine tool. During production has great practical hydraulic special milling machine, can with hydraulic drive size produces different nature of the milling machine. This design is mainly with my own knowledge will be applied to design of auxiliary materials, strengthening and deepening prior knowledge of hydraulic system design calculation, the general procedure and method to determine the correct method of actuator, choose standard hydraulic ponents, can skilled using hydraulic basic circuit, position satisfy basic performance requirements of the hydraulic system. In the design process of the main is drawing, which not only can clearly drawn designed by the pleteness of the contents will show out, still can see whether the knowledge already plete mastery.
