The ordinary drill is a single drill. It will improve its productive efficiency, shorten its processing time if assembled a multiple spindle case on. That so calls a multiple drill. Hereby, the keystone of this design paper is how to design a multiple spindle heads. The design subjects include the selection and distribution of gear wheel, the design of spindle, and the guiding equipment and selection of the multiple spindle heads, etc.The multiaxial drilling machine is a lind of can meet the requrements of the shaft and processing drilling machine.Such as guidance,power,and speed and processing in range,etc.Paris exhibitiong display in the multiaxial drilling machine attractive to hydraulic into.The whole work cycle such as quick in,work into and cleaning oxide and are automatically.It is worth nothing that,many with single speed changing institutions,so can adapt to a group of different diameter hole processing demand.Many axis machine high production efficiency;Less investment;The processing components adaptability is strong;Flexibility is good;Processing precisionis high,the product quality is stable;Reduce the labor intensity;Production preparation period is short;The retrofit products when equipment loss less.And with the development of numerical control technology,the axis machining scope will be more and more wide,processing efficiency unceasingly will also improve.Key words: Multiple Drill；Productive Efficiency；Multiple Spindle Heads；Orientation Device；Gear Transmission Box
