任何磨加工机床在磨削加工中,一般都少不了使用冷却液。目前各厂广泛采用的冷却液是乳化液(切削油2～39％,碳酸钠0.3～0.4％,亚硝酸钠0.3％,水余量),这种冷却液虽然也具有一定的冷却及润滑作用,但满足不了我厂生产超C级轴承的要求。根据超C级轴承生产的需要,参考了轴承译丛1965年第1期所介绍的资料,我厂配制了二种新成份的冷却液,效果很好,即减少了烧伤,又比乳化液提高了表面光洁度2～3小级。现将配方介绍如下,以供参考。
Any grinding machine tool in the grinding process, generally indispensable to the use of coolant. At present, the widely used coolant is emulsion (cutting oil 2 to 39%, 0.3 to 0.4% sodium carbonate, 0.3% sodium nitrite, water balance), although this cooling fluid also has some cooling and lubrication , But can not meet the requirements of our factory to produce super C-class bearings. According to the super C-class bearing production needs, with reference to the information translated into the first issue of 1965, I plant the preparation of the two new components of the coolant, the effect is good, that is to reduce the burn, but also increased than the emulsion The surface finish 2 to 3 small. The formula is introduced below, for reference.
