摘要 Abstract In a comprehensive study of the structure of the grinding machine, based on the principle of integrated overall size of the hydraulic system on the overall layout and design of the hydraulic system of the grinder. The outer surface of the M1432 Universal cylindrical grinding machine mainly grinding cylindrical or conical (including ladder) and a bore, precision can reach 1-2 grade, surface finish of T8- T10. The hydraulic system has a higher, more complex requirements. Automatic reciprocating motion work action, fast forward and backward grinding tail-stock, retractable hydraulic action and the necessary interlock system. Hydraulic technology since the late 18th century Britain made the worlds first hydraulic press date, more than 300 years of history, but its real development only time in 50 years after World War II, the postwar hydraulic technology to rapidly civil industry, in machine tools, construction machinery, agricultural machinery, automobile and other industries gradually. Present since the 1960s, with the development of atomic energy, space technology, computer technology, hydraulic technology has been greatly developed, and penetrate into various industrial areas as well. The current hydraulic technology forward pressure, high speed, high power, high efficiency, low noise, durable, highly integrated direction. With the accelerated pace of science and technology, hydraulic technology has been widely applied in various fields, the hydraulic system has become one of the most critical part of the host device. This paper studies the hydraulic drive system, hydraulic drive system design needs with the overall design of the host simultaneously. Design must be from the actual situation, organically combine various forms of transmission, give full play to the advantages of hydraulic transmission, strive to design the structure is simple, reliable, low cost, high efficiency, simple operation, easy maintenance of the hydrauli
