Improvement of manufacturing equipment, making an important equipment manufacturing industry as a wide range of machining processes and equipment have been many new changes, especially the hole processing, in today39。s hydraulic system is being more and more important. Boring machine hydraulic system design, in addition to the host in action and meet the performance requirements of the provisions, but also must meet the small size, light weight, low cost, high efficiency, simple structure, reliable operation, convenient use and maintenance of a number of generally recognized design principles. The design of the hydraulic system is the basis of known conditions to determine the work program of hydraulic, hydraulic flow, pressure and hydraulic pumps and other ponents of the design. To sum up, the need to plete the entire design process to conduct a series of hard work. In recent years, in particular with the microelectronics, puter technology, so that the hydraulic technology has entered a new stage of development. At present, it has been widely used in industry in various fields. In recent years, microelectronics, puter technology, hydraulic ponents to further improve manufacturing technology, so that hydraulic technology as a fundamental, not only in traditional form but also occupies an important position with excellent static and dynamic performance has bee an important means of control.Enter here Abstract In this paper, focused on the bination of dualuse horizontal boring drilling machine hydraulic system, to achieve the duty cycle is: work fast forward feed situ rapid return to stop, hydraulic technology is mechanical equipment in the fastest growing technologies.
