所谓含氟导轨材料就是含有聚四氟乙烯(PTFE)成分的两种或两种以上的组分混合或组合的复合材料。复合的目的是要获得低摩擦系数、耐磨、无爬行、自润滑、吸振、高刚度等优异性能的新型导轨材料,以代替其它昂贵的减摩耐磨导轨,提高机床产品质量,延长机床导轨使用寿命。一、含氟导轨材料的共同特性1.减摩、耐磨性好:PTFE是固体材料中摩擦系数最低的自润滑材料,仅0.04。加入填料改性的PTFE导轨材料仍具有较低的初始摩擦系数(0.05～0.08)。由于嵌入性好,硬的磨料微粒污染时自身耐磨性反而
The so-called fluorine-containing rail material is the composite material containing two or more components of polytetrafluoroethylene (PTFE) mixed or combined. The purpose of compounding is to obtain new guide material with excellent performance of low friction coefficient, wear resistance, non-creep, self-lubricating, vibration absorption and high rigidity, so as to replace other expensive anti-friction and wear-resistant guide rails to improve machine tool product quality and extend machine tool guide Service life. First, the common characteristics of fluoride-containing rail materials 1. Anti-friction, good wear resistance: PTFE is the lowest friction coefficient of solid materials, self-lubricating material, only 0.04. Addition of filler modified PTFE rail material still has a lower initial coefficient of friction (0.05 ~ 0.08). Due to good embedment, hard abrasive particles pollute their own wear resistance instead
