With the development of machinery industry in the drilling industry in many parts require more complex drilling, but using ordinary single-axis drilling process is now out of shape, or than a single part, multi-processing and production efficiency for the single hole is very low . Although CNC has been able to achieve multi-axis drilling, but also easy to operate, but its high economic costs, maintenance costs are also high. There is an urgent need for multi-axis machine tool feed system research and design, in order to increase the processing part of the shape change, while improving the precision machining parts. In line with the principle of practicality, coupled with the design requirements of the design into account, the application of this design servo motors, bearings, ball screws, rails, columns and other areas of knowledge. For this design, first of all, a lot of information related to access and enrich the theory of knowledge; Secondly, according to the experimental design requirements related to record each of the experimental results and the experimental problems arising in the process; Finally, the analysis of experimental result
