Main features of step-up structure
① The z-direction guide rail is installed horizontally. The 4 slides can evenly share the weight and cutting force of the saddle, reduce the ball wear of the slider, and improve the service life of the guide rail.
② The inclined bed of high and low level guide rail is in the same state in the process of processing, assembly and use, which can effectively ensure the accuracy of the machine tool.
