ABSTRACT

Transfer and unit machine is more efficient, more accurate and lower cost. Combination machine is designed according the fundamental, which highly centralized, or, more correctly. The topic of design is that the design of combination machine, which can boring the TaiShan-12 front gearbox. 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. We can referent some standard books to select general parts, compute cut feed and productivity. Finally we will determind the relationship of every part, draw a sketch map of the machine and productivity card. Finally we finish the design. The theoretical
Calculation of productivity indicates that the design can satisfy the production request.
