【摘要】 本文系统地介绍了非金属材料用作机床导轨的耐磨性能和试验方法,并对国内外同类产品进行了评价。同时还考察了不同加工工艺和表面处理方法的配合件对其耐磨性的影响,测定了在油润滑和干摩擦下的摩擦系数。结果表明,填充聚四氟乙烯塑料软带和FQ-1三层复合材料的摩擦系数低,耐磨性最好,配合件以砂轮周边磨削加工为宜。经离子氮化处理的38CrMoAl钢与填充聚四氟乙烯软带作配合副的磨损量最小。更多还原

【Abstract】 Wear resistance of non-metallic materials for guides ofmachine tools was presented with different experimental methods,and that of the similar products from internal and external was evaluated. The effects of the mates with different machining technology and surface treatments on wear resistance were examined.The friction coefficients of these materials during oil lubrication and dry friction were measured.The results showed, filled PTFE soft belt and FQ- 1 three layers composite had low friction coefficients and the best wear resistance.The mates of these materials could grind with circumfrence of abrasive wheel.When 38CrMoAl steel with ion-nitrodation sliders on filled PTFE soft belt, the wear value was the least.更多还原
