The system can automatically complete the machine's action cycle such as fast-forward, working forward, rewind, and release the clamping, by this, the worker’s labor intensity has been reduced and the production efficiency has been improved. On the basis of the requirements of the working cycle of single multi-axis combination drilling machine, the work of this paper are: the hydraulic system design, PLC control system design and hydraulic design. Complete hydraulic system design of the main hydraulic system schematic formulation, calculation and selection of hydraulic components; control system to control the main operation flow chart of the proposed system, I / O port allocation, wiring and programming, and drawing on machine debugging; hydraulic station are designed primarily to determine the structure of the form of hydraulic, fuel tank structural design and in Pro / e environment oil block design. Key words: hydraulic; PLC control; hydraulic system; combination machine; Pro / EII...
