This design is mainly for power hydraulic transmission platform system design of modular machine tool. The application of hydraulic system in machine tool can realize machine tool automatic feed, and can make machine tool movement more balanced, machining accuracy higher, more efficiency, so as to realize machine tool automation. Combination drilling machine series, standardization of the general components as the foundation, special-purpose machine tool with a small number of special components composition, suitable for product mass, one or more at the same time group processing, machine processing equipment, which hydraulic power sliding table is an important group into parts. Through this topic design training, enable us to fully familiar with the process, combination machine tools, hydraulic power sliding table composition and working principle. On this basis, the design of hydraulic system of power slipway to complete a giv
