Creep phenomenon of polyethylene guide rail. Crawling can reduce the positioning accuracy or improve the roughness value of the workpiece surface to be machined. / /
(1) make the guide rail work under the condition of liquid friction as far as possible, in order to reduce the frictional resistance, reduce the driving power and improve the power level.
(2) friction damage of guide rail to prevent corrosion. The flow of oil also serves as a wash.
(3) Avoid the crawling phenomenon and continuous vibration under low speed and heavy load.
(4) The high speed friction heat decreases and the thermal deformation decreases in turn. Polyethylene guide rail moves smoothly at low speed. The frictional self - excited vibration of moving guide is easy to occur at low speed or small displacement.
Polyethylene guide: Ball guide, roller guide, needle roller guide, polyethylene guide depends on the external load and the weight of the components, so that the two guide surfaces remain attached over the entire length of the guide. Ultra-high molecular weight polyethylene guide rail with pressure plate as the guide surface, to ensure the adhesion of the main track surface. Circular motion of polyethylene guide rail: the relative motion track of guide rail pair is circular, such as the disc and base guide rail of vertical lathe. Linear motion of polyethylene guide rail: the relative motion track of guide pair is a continuous straight line. Such as common lathe sliding plate and bed guide rail.
