【正文】 Application of bined highvolume machining parts, high efficiency, high productivity is the development direction of machining. The graduation project is entitled Crankcase front end of drill hole. The bination of milling machine tool required to achieve both ends of surface, can be manual, 10mm milling head can be finetuning. Making process in the process, conducted by volume ends face milling processing program, and to seek the best technology solutions, which illustrates the process in the importance of the production process. The main elements of my design are: the general layout for a machine tool design。 Integration for the fixture design。 milling head。 Manual 河北工程大學(xué)畢業(yè)設(shè)計(jì) 3 河北工程大學(xué)畢業(yè)設(shè)計(jì) 1
