In order to deal with the question of the translation in guide and positioning, the table and wheel frame of the cnc milling machine are installed with self-developed cross- roller guides positioning device guide-ways. Usually, there are two kind of guide rail, they are rectangular guideway(the same as hard guideway) and linear guide rail. Rolling linear guide rail is placed between the slider and a special roller so that the sliding friction between the slider and the rail into rolling friction. This greatly reduces friction between the two sports to gain. The difference between the move and static friction is small, with excellent mobility, which the interval of time between the driving signal and the lag action of mechanical is very short, which is beneficial to improve the response speed and sensitivity of CNC system.
Moreover, for high precision automatic control milling machine, the work-piece clamping mechanism is divided into several parts, which includes gear assembly and feed control lever assembly. What around the work-piece chuck body are mounted on the left and right spindle, spindle mounted in the left and right the sleeve through bearings, the sleeve has the right bottom feed alveolar. And feed gear with the completion of the feed movement, gripping and releasing the work-piece.
