Combination machine is designed according the fundamental , which highly centralized ,or , more correctly it can process one working procedure or more different working procedures at one time . Combination machine was developed in the end of industrial production compared with traditional machine; combination machine has many advantages , such as high efficiency , high accuracy and low cost . It is composed of some general parts , such as bed ,column ,work able ,power unit ,and some special parts designed according to different work piece machining need. The preface of a lot of works can be completed on the combination machine, but in regard to the majority current usage of combination machine, then and primarily used for the flat surface to process and the bore to process two big work preface. The main part including :(1) Formulating technological plan We,ve learned the characteristic of the part designed ,accuracy and specification ,locating and fixing ,productivity and machining structure by the practice .Then the technological operation and work order can be determined which can be finished in combination machine.(2) Combination machine frame design determines the interrelation of the different part in the machining tool ,select general parts and tool oriented .Then compute cut feed and productivity finally draw a sketch map of the machine .(3) Combination machine parts design including headstock、proper transmission layout 、shaft and gear move f
