Application of modular machine tool processing large quantities of spare parts, high efficiency, high production efficiency is the development direction of mechanical processing. It generally USES multiple spindle, knife, working procedure, polyhedral or transfer process at the same time, the production efficiency is higher than general machine tools several times or more. Because gm parts has standard combined seriation, can be flexibly configured according to need, to shorten design and manufacturing cycle. Combination machine tools, therefore, both the advantages of low cost and high efficiency, is widely used in the mass production, and can be used to form automatic production line. This topic for the engine shell on the end face 3 xm12 hole drilling this specific process and design of a dedicated vertical combination machine tools. In this design, I design the main contents are: the machines overall layout design; On the machine tool feeding and transmission part of the design; Combined with examples, this paper introduces the fixture design method; Through this design, the machine can completely meet the design requirements. In full data calculated on the basis of the careful selection of standard general parts, according to the structure characteristics of the processed parts, machining parts dimensional accuracy, surface r
