目前,我国机械行业在金属切削加工过程中使用的切削液,92％左右是乳化油,8％左右是矿物油或动植物油,只有0.5％以下是无油切削液。使用油类作为切削液有两大弊端:浪费能源,造成污染。在当前我国能源紧张、污染严重情况下,金属切削加工使用油类作为切削液,显而易见,并不妥然。无油切削液具有较好的冷却性、清洗性,并具有一定的润滑性、防锈性,基本可以满足 At present, China’s machinery industry in the metal cutting process using cutting fluid, about 92% is emulsified oil, about 8% is mineral oil or animal and vegetable oils, only 0.5% of the following is oil-free cutting fluid. The use of oil as a cutting fluid has two major drawbacks: waste of energy, causing pollution. At present, China’s energy shortage, serious pollution, the use of metal cutting oil as a cutting fluid, it is obvious, not necessarily. Oil-free cutting fluid has good cooling, cleaning, and has a certain lubricity, rust-proof, the basic can meet
