金属切削机床的大部分滑动导轨都是以铸铁对铸铁接触作滑动导向,由于摩擦系数大、润滑不良、防尘措施差等因素,致使导轨磨损严重,影响工作精度和寿命。随着塑料工业的迅速发展,越来越多工程塑料相继出现,聚四氟乙烯导轨板(简称F4板)就是其中的一种,将这种材料粘贴于机床导轨,比起其它导轨结构更为经济、耐磨、优越。F4板质软,化学性能稳定,与金属相对滑动摩擦时,摩擦系数较低、而且稳定,其摩擦系数值一般为0.04左右,F4板
Most of the metal cutting machine tool sliding guide rail are made of cast iron sliding contact-oriented, due to the friction coefficient, poor lubrication, poor dust control measures and other factors, resulting in serious rail wear, affecting the working accuracy and life expectancy. With the rapid development of the plastics industry, more and more engineering plastics have appeared one after another, Teflon rail plate (referred to as F4 plate) is one of these, the material is pasted on the machine guide rail, compared with other rail structure Economic, wear-resistant, superior. F4 board soft and stable chemical properties, and metal relative sliding friction, the friction coefficient is low, and stable, the friction coefficient is generally around 0.04, F4 board
