Abstract
This article mainly told the research, the designing and transformation on the longitudinal motion system and track lubrication mechanism of CA6140 economic medium precision NC machine. The article made a brilliant exposition on the designing and transformation scheme of the longitudinal motion system and track lubrication mechanism of NC machine. The article also exposed brilliantly the mechanism’s mail parts: the ball-race bearing, the servo-electric machine, the coupling and so on. Doing the design is for the sake of improving the site precision, duplicate site precision and transformating the Longitudinal motion system .So it can work credibility, meet the request of every property norm, come to the expected consequence, and fulfill the require of design assignment list. Besides, the author has designed and drawed all of mechanism’ parts, and also drawed the assemble chart. This mechanism is simple and reliable, it can apply to every similar NC machine.
Key words: NC machine Longitudinal motion system Track lubrication mechanism
