           Summary
   I graduated from this design is the subject of design modifications reducer combination boring lathe and machining jig design. Replace parts of the complex structure and size. To increase production efficiency and reduce labor intensity, specially designed one-precision combination of smooth-bore three main bearings Kong and dedicated jig boring lathe. The design specification can be divided into four parts :  
The first part of the preparation for mechanical machining, summary and analysis of the role of crafts for blank parts manufacture, processing options and to develop processes for the base line, identifying machinery allowance, size and cutting processes consumption. 
 The second part was the design portfolio boring lathe. The machine tools are designed for paper processing unit combination machine tools. From her position and Jiajin reliable guarantee starting precision processing, printing of non-rigid axle portfolio choice horizontal boring lathe. And the mapping of the manufacturing processes, and processing paper maps and horizontal linkages portfolio boring lathe size chart.  
Part dedicated jig into the design. Jig design is one of the main elements of this design. In the design of the jig to the error analysis, but also for calculating Jiajin power to ensure that meet processing requirements. 
 Finally, foreign language translation technology and the preparation of brochures.
