钛合金车削中的低温油膜水滴冷却润滑技术

The Cryogenic Oils on Water Cooling Technology in Turning Process of Titanium Alloy

简述了低温油膜水滴(cryogenic Oils on Water,低温OoW)切削液的冷却润滑原理。通过测量常规浇注、低温冷风和低温OoW切削液三种冷却润滑方式下切削钛合金的切削温度、刀具寿命和工件表面质量的对比试验,研究低温OoW切削液的冷却润滑性能。试验结果表明,低温OoW切削液具有良好的冷却润滑效果,能有效降低切削温度、提高刀具寿命和降低表面粗糙度值,且在切削速度提高时,对比效果更为明显。

It briefly introduced the cooling and lubricating principle of cryogenic Oils on Water （cryogenic OoW） cutting fluids. Performances of cryogenic OoW were compared with respect to cutting temperature,tool life and surface roughness during the turning of titanium alloys under three cooling and lubricating conditions （i.e.flooding,compressed cold air,and cryogenic OoW）. The experimental results show that with cryogenic OoW as coolant and lubricant the cutting temperature is further reduced, the tool life extended and the sufrace roughness value decreased. With the increase of cutting speed,the performance of cryogenic OoW becomes more obviously.
