Abstract
CK6150machine tool major component includes: headstock, tool slide, tailstock, feedbox, apron and bed. This design mainly aims at the headstock of the CK6150 machine tool .The headstock of machine tool is a quite complex transmission part. The design content mainly includes determines the machine tools main parameter, Draws up the transmission plan and the transmission scheme, Calculated and examined the main spare part，And used specialized charting software to carry on the components design and processing.
NC advanced manufacturing technology is the basis of technology. NC in the modernization of production showed great superiority. To the modern manufacturing, numerical control machine tools suitable for those who shape very complex, sophisticated and small quantities of parts, And general machine tools simply can not meet this requirement. Modern CNC machine tools highlight the advantages of high-precision processing can be carried out and diversification of processing, can replace the other processing methods.
