ABSTRACT:The hydraulic control system plays an important role in the machine tool, hydraulic control system design is an important part of the combination of machine tool design. The pros and cons of the hydraulic control system performance determines the overall performance of the machine tool.

　　　Characteristics at the same time take full advantage of the hydraulic design manual software simple and convenient to use the view of the mechanical system design and optimization of modern design, according to the known conditions, a whole new way: fast, efficient optimization method is more scientific, comprehensivethe better performance of the drilling machine tool power sliding hydraulic system. This paper, the combination drilling machine, hydraulic power sliding system design of the main contents are as follows:

　　　Chapter I: drilling machine working conditionsDrilling machine conditions analysis, the full use of the shortcut to the Hydraulic Design Manual, and practice from the empirical formula, data, easy to quickly calculate the speed of the actuator load changes in the law.    Chapter II: The hydraulic system designDrilling machine system design requirements, analysis of system conditions, the use of modern design methods program system to optimize the design and morphological matrix, the combination of traditional design, a new hydraulic system design methodology is more efficient than the previous design , save time, and more optimized.    Chapter III: hydraulic cylinder design and hydraulic components to selectHydraulic cylinder design, the parameters of the hydraulic system to calculate and select hydraulic components, to determine the specifications of various models of circuit components, hydraulic system diagram of the selected combination of hydraulic components according to the design of the system diagram and working conditions of Figure the hydraulic control system to drive power sliding.    Chapter IV: checking hydraulic system performance

　　　The hydraulic system for analysis and checking, to ensure that the system can accurately and reliably complete the graduation project anyService book required by the duty cycle.
