摘　　要：根据液晶的减摩作用，研究了液晶作为润滑添加剂在改善机床爬行状况，即降低其爬行临界速度方面的实际应用。选择了3种液晶，每种都按6种不同的浓度加入到N32（旧标准HJ20）机械油中，在M7130型平面磨床上进行了试验。试验结果表明，液晶作为润滑添加剂确实具有良好的防爬作用，且防爬效果与液晶种类及其添加浓度有关。An research is made on improvement of stick slip condition by use liquid crystal as lubrication additive based on the anti - friction action of liquid crystal. It is a practical application of liquid crystal to lower the critical speed of stick slip. 3 kinds of liquid crystal are selected and mixed into machine oil N32 (the old standard: HJ20 ) with 6 different concentritions. The experiments are made on M 7130 surface grinder. The experiment results show that, the liquid crystals used as lubrication additive have good preventing action for stick slip and the effects of stick slip prevention are different by type of liquid crystal and the concentrations.
