Rail Application

The sliding guide has the advantages of simple structure, convenient manufacture and high contact rigidity. However, the traditional sliding guide rail has large friction resistance, rapid wear and tear, and the difference between the dynamic and static friction coefficients is large, and the phenomenon of crawling is easy to occur at low speed. In order to improve the positioning accuracy and motion stability of CNC machine tools, plastic guide rails have been widely used in CNC machine tools at present. The friction factor is small; the dynamic and static friction factors are similar, the motion stability is good, and the phenomenon of low-speed crawling can be prevented; the wear resistance is good, and it has self-lubricating effect and vibration resistance;

Generally speaking, the most notable features of sliding plastic guides are their excellent rigidity, vibration absorption (suppressing the vibration generated when the tool is cutting) and damping (preventing the vibration when the guideway system starts or stops), which are suitable for machine tools with large cutting loads. , and the cost is low, economical and practical.
