微量油膜水滴切削加工不锈钢的效果试验研究 总被引:3,自引:0,他引:3
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。 相似文献

TC4铣削中超临界CO2混合油膜附水滴的冷却润滑性能 总被引:1,自引:0,他引:1
在干切削、超临界CO2(scCO2)以及scCO2与油膜附水滴(OoW)混合三种绿色切削方式下对钛合金进行了铣削试验。通过单因素试验分析了铣削参数和冷却润滑方式对切削力、切削温度、表面粗糙度的影响规律,研究了scCO2与OoW混合冷却方式在钛合金铣削中的冷却润滑性能。结果表明,三种冷却润滑方式下,随着切削速度、每齿进给量和径向切宽的增大,切削力和切削温度均呈现增大趋势;当切削速度进一步增大时,依据高速切削加工理论,切削力和温度有增长变缓和下降的趋势;不同加工参数下,相比干切削和scCO2,scCO2与微量油膜附水滴混合冷却方式能有效减小切削力和降低切削温度,并获得良好的加工表面,具有良好的冷却润滑性能。 相似文献

Experimental studies on the performances of both new developed environmental friendly vegetable based cutting fluids (refined sunflower and canola oils) including different percentage of extreme pressure (EP) additive and two commercial cutting fluids (semi-synthetic and mineral cutting fluids) in turning processes were reported in this work. Performances of cutting fluids were compared with respect to surface roughness, cutting and feed forces and tool wear during longitudinal turning of AISI 304L. Experimental results were also compared with dry cutting conditions. The results indicated that 8% of EP included canola based cutting fluid performed better than the rest. 相似文献
