我厂从瑞士进口的6A型高精度座标镗床的导轨润滑,因随机所带润滑油料用完,影响该设备的正常开动。我们经反复调配和试验,制成“自配90号精密机床导轨油”,经石油化工科学研究院鉴定,其运动粘度分别为96.2厘沲/50℃和14.3厘沲/100℃,粘度指数不小于90,临界负荷不小于90公斤,闪点不低于230,铜片腐蚀试验合格,无水溶性酸、水份和机械杂质,基本达到国产90号精密机床导轨油的质量指标和使用性能,后又经八个月的使用证明,有消除爬行,减少摩擦面噪音等作用,满足使用要求,现介绍如下:
Our factory imported from Switzerland, 6A high-precision coordinate boring machine rail lubrication, due to the random lubricant material used up, affecting the normal operation of the device. We have repeatedly formulated and tested to produce “self-aligning precision metal guide rail 90”, identified by the Institute of Petrochemical Technology, its kinematic viscosity was 96.2 centistokes / 50 ℃ and 14.3 centistokes / 100 ℃, the viscosity index is not Less than 90, the critical load of not less than 90 kg, flash point of not less than 230, copper corrosion test pass, no water-soluble acid, water and mechanical impurities, basically reached 90 precision machine tool rail oil quality indicators and performance, After eight months of use proved that there is to eliminate crawling, reducing friction surface noise and other functions to meet the requirements, are presented below:
