微量润滑(MQL)是一种很有前途的新型磨削流体输送技术。然而，在这样的冷却条件下，该过程的热行为仍不清楚。本文报道了微细平面磨削中MQL的最新研究结果。实验研究考虑了三种情况：常规低压流体输送、干法研磨和MQL输送。普通钢EN8、M2和EN31用通用氧化铝砂轮研磨。所使用的常规液体是体积分数为5%的通用乳化液；MQL液体是一种通用机械加工油。用单极热电偶法测量了磨削温度。将实验得到的磨削温度与理论预测的磨削温度进行了比较。结果表明，在所研究的条件下，MQL可以提供与常规洪水相似的热性能。对磨削运动学进行了讨论，以解释结果并提高对MQL磨削性能的理解。
Minimum quantity lubrication (MQL) is a promising new fluid delivery technique in grinding. However, the thermal behaviour of the process under such cooling conditions remains unclear. This work reports on the results of a recent investigation of MQL in fine-cut plane surface grinding. The experimental study considered three conditions: conventional low pressure fluid delivery, dry grinding and MQL delivery. Common steels EN8, M2 and EN31 were ground with a general purpose alumina wheel. Conventional fluid used was a general purpose 5% by volume emulsion; MQL fluid was a general purpose machining oil. Grinding temperatures were measured using the single-pole thermocouple method. Grinding temperatures obtained from experiment are compared with those predicted from theory. Results obtained demonstrate that MQL can deliver a comparable thermal performance to conventional flood delivery under the conditions investigated. Grinding kinematics are discussed to explain the outcomes and to improve understanding of MQL grinding performance.
