摘　　要：主要应用微量油膜水滴切削液,在C620-1普通机床上,通过改变切削速度、进给量以及调整喷嘴的喷射角度,对奥氏体1Cr18Ni9Ti不锈钢材料进行切削加工的效果试验研究。试验结果表明,与干切削、乳化液切削相比,微量油膜水滴切削不仅能够有效地降低切削力和加工表面粗糙度,而且其刀具寿命分别是干切削、乳化液切削的2.28倍和1.6倍。在喷射方向效果研究中,微量油膜水滴在对刀具后刀面和侧面进行喷射的切削加工效果更佳。试验研究表明,微量油膜水滴切削液具有一定的冷却效果和良好的润滑效果。Mainly carries out the experimental studies on the cooling and lubrication effects of Oils on Water （OoW） machining stainless steel （1Cr18Ni9Ti） on the C620-1 conventional lathe by changing cutting speeds and feed rates as well as adjusting spraying angles of the nozzle. The results show that OoW cutting fluid can effectively lower cutting forces and decrease values of the machined surface roughness by comparing to dry cutting and emulsion. Also,tool life of OoW cutting fluid is 2. 28 times and 1.6 times of dry cutting and emulsion,respectively. In three spraying directions of OoW,spraying to tool flank or side face has a good machining action. Clearly, these researches further demonstrate that OoW cutting fluid has a good cooling effect and a better lubricating effect.
