The NC Reform Of CA6140Type Lathe

Various mechanical processing industry in today’s society in the rapid development ofthe lathe as an indispensable position of the tool in the processing industry has also beentoward high-precision, high efficiency, high automation direction development, NC machinetools has become a mainstream device, gradually replace the old ordinary lathe. China is adeveloping country, due to the late start of the modern industrial development, the technologyis relatively backward, with a lot of the old machine, but also because of the lack ofprofessional repair and maintenance, prompting the machine accuracy greatly reduced. Theprice of the purchase of new NC lathes from abroad they are quite expensive, ordinarycompanies can not afford to change the status quo, and thus through the reform of NC Lathe.By ordinary lathe NC reform depending on the characteristics of the NC machine tools,can greatly improve processing efficiency, while the reform of the cost is much lower than there-purchase the new machine will bring considerable profits, thus boosting the economicdevelopment of China’s industrial. NC transformation of the foreign technology has beenbasically formed an industry, China should learn from their experience, and gradually formedan independent numerical transformation of industry has greatly enhanced the rate of NCmachine tools in China.In this thesis, the CA6140ordinary lathe to reform its mechanical structure parts, and theformation of new feed system. To adopt8031CPU control system, issued by the step pulse,slow transmission to drive the ball screw movement, to complete vertical and horizontal feedmotion while controlling the turret movement to make it into the automated.
