Simulation Study on Minimal Quantities of Lubricant Grinding Temperature Field for High Hardness and Difficult Machining Materials
Under the background of intelligent manufacturing,the development of material science and the improvement of the precision level of key core parts,especially the wide application of emerging high hardness materials,the new challenges to grinding precision machining are presented.The high temperature in the grind-ing contact zone is the core factor which astricted high precision machining for grinding.At the same time,the proposal of reducing cost and increasing efficiency and green environmental protection processing has promoted the application of minimal quantities of lubricant(MQL)technology in the field of grinding processing.In this paper,a three-dimensional transient grinding temperature field mathematical model and a numerical simulation model were constructed by combining the grinding heat generation mechanism and the grinding surface enhanced heat transfer mechanism.The temperature field simulation research of MQL grinding of high hardness and diffi-cult machining materials was carried out.Which provided a theoretical basis for the application and promotion of MQL green grinding cooling method of high hardness and difficult machining materials.
