动植物油本身是一种优良的油性添加剂,在金属切削加工中,可直接或复合用作切削油,具有良好的润滑性能。实践证明,在矿物油中,加入一定量的油性极压添加剂配制的极压切削油(或极压乳化液),同样具有良好的润滑性能,甚至有比动植物油更高的极压性能和安定性,完全可以采用极压切削油代替动植物油。极压切削油配方:氯化石腊20％;6411(二烷基二硫代磷酸锌)1％;
Animal and vegetable oil itself is an excellent oily additives, in metal cutting, can be used directly or composite cutting oil, has good lubricating properties. Practice has proved that, in mineral oil, adding a certain amount of extreme pressure oil additives formulated extreme pressure cutting oil (or extreme pressure emulsion), also has good lubricating properties, and even higher than the animal and vegetable oils extreme pressure performance and stability Sex, can use extreme pressure cutting oil instead of animal and vegetable oils. Extreme pressure cutting oil formula: chlorinated paraffin 20%; 6411 (dialkyldithiophosphate) 1%;
