Design of CA6140 Spindle and Spindle Parts

Abstract:CA6140 spindle components from the spindle, the spindle support and installed in the spindle on the transmission parts, seals and other components. The  accuracy motion and rigidity are structural of the components spindle important factors in processing determining the quality and cutting efficiency. By faunction unederstanding spingdle the strurcture and spindle of the CA6140 designed leathe spingdle and comerponents, the spindle and components are to improve the performance of the spindleComponents.

As the design mainly main deisign tole,the CA6140 maichinte is turning deisign systiem the in maichining spindle industry tool, this is for the CA6140 main machine, maiine is mainily the paraimeters of the maichine to detiermine the drilve used of the widely proigram and the transmission of the diagram of the preparation of some of the major parts are also related to the calculation and checking, the use of software three-dimensional design drawing for paper a lot of progress parts introduces and the contents, processing. CA6140 machine tools as China's main tuirniny the prociessingg maichine, have be widily used in the prececsing of maichinery industry. This article first the metal cutting machine tool in the research situation inside and outside China, and the gap between the development at home and abroad. T Finally, ideas, main methods and of the research of this are also elaborated. 

Key words: CA6140; spainddle box; mieatall it cuting maechine tole.
