在金属切削过程中,刀具前刀面与切屑之间,刀具后刀面与工件的界面之间存在着很大的摩擦,使切削力、切削热、切削温度和工件变形增加,直接导致刀具磨损,同时也影响已加工表面粗糙度和零件精度等表面质量。采用切削液就是为了改善干切削时的切削条件。合理选用切削液,或者研制切削性能良好的切削液应用于金属切削中,可以改善切削过程中各界面的摩擦情况,减少刀具与切屑的粘结,抑制积屑瘤和鳞刺的生长;降低切削温度,减少工件的热变形;减小切削力,保证加工精度,提高刀具寿命和生产效
In the metal cutting process, the tool rake face and the chip, the tool flank and workpiece interface there is a big friction between the cutting force, cutting heat, cutting temperature and workpiece deformation increases, leading directly to tool wear , But also affect the surface quality of machined surface roughness and part accuracy. The use of cutting fluid is to improve the cutting conditions of dry cutting. Reasonable choice of cutting fluid, or the development of cutting fluid cutting fluid used in metal cutting, can improve the cutting process of the interface friction, reduce the bonding tool and the chip, inhibit the growth of the BUE and scale; reduce cutting Temperature, reduce the thermal deformation of the workpiece; reduce the cutting force, ensure machining accuracy, improve tool life and production efficiency
