塑料导轨材料的主要性能是指摩擦磨损性能、机械性能和热性能。如何提高机床的精度及延长使用寿命,这与所选择导轨材料的摩擦磨损性能有直接关系。对于塑料导轨材料,要求具有低的摩擦系数,高的耐磨性及无爬行这三个主要的摩擦学特性。一、摩擦磨损性能的测定1.摩擦系数的测定塑料导轨材料无论是板状类、涂层类或软带类,其摩擦和磨损性能的快速评定试验均可通过阿姆斯拉(Amsler)试验机(国内同类型试验机为M-200型磨损试验机)或梯姆肯(Timken)试验机来进行。其测试的基本
The main properties of plastic rail material refers to the friction and wear properties, mechanical properties and thermal properties. How to improve the accuracy of the machine tool and extend the service life, which has a direct relationship with the friction and wear properties of the selected guide rail material. For plastic guideway materials, three major tribological properties are required: low coefficient of friction, high wear resistance and no creep. First, the determination of friction and wear performance 1. Determination of friction coefficient Whether the plastic rail material plate type, coating or soft belt class, the rapid assessment of friction and wear performance tests are available through the Amsler (Amsler test Machine (the same type of testing machine for domestic M-200 wear testing machine) or Timken (Timken) testing machine to carry out. The basic test
