切削液的优劣,除要求理化性能符合规定指标外,更重要的是在金属切削中能否满足最佳的切削条件,即在其它条件(如切削速度、进给率、切削材料、刀具等)相同的情况下,切削液对刀具寿命、切削比、切削力(扭矩、轴向力、径向力)、振动、温度、工件表面光洁度等均产生影响。为此要做机械性能的评价。目前,我国对切削液的评价,仍然停留在一般理化性能的检验和润滑性能的评价,对切削液的机械性能试验尚未开始。国外在这方面有较多的报导,下面综述用车削、镗削、钻孔、攻丝等试验对切削液性能评价的方法,可归纳为非切削和切削试验两类。
The merits of the cutting fluid, in addition to physical and chemical performance requirements meet the prescribed indicators, more importantly, metal cutting can meet the best cutting conditions, that is, under other conditions (such as cutting speed, feed rate, cutting materials, cutting tools ), The cutting fluid has influence on the tool life, cutting ratio, cutting force (torque, axial force, radial force), vibration, temperature, workpiece surface finish and the like. To do this mechanical performance evaluation. At present, China’s evaluation of cutting fluid, still stuck in the general physical and chemical properties of the test and lubrication performance evaluation, the cutting fluid mechanical properties test has not yet begun. Abroad in this area have more reports, the following review with turning, boring, drilling, tapping and other tests on the cutting fluid performance evaluation methods can be summarized as non-cutting and cutting test two categories.
