“…Their research demonstrates that compared with traditional flood cooling grinding, the costs of MQL grinding fluid are lower by 65%, and device investment is also lower by 22%. In addition, using naturally degraded synthetic esters as lubricants, the grinding fluid has minimal harmful effects on the environment and human (Li et al, 2012a). da Silva et al (2007) studied the surface completeness of the workpiece, specific energy, and abrasion contrast of a grinding wheel under different conditions, including dry grinding, flood cooling wet grinding, and MQL.…”

Abstract:The heat-transfer model of a surface grinding temperature field with a nanoparticle jet flow of minimum quantity lubrication (MQL), as well as the proportionality coefficient model of the energy input workpiece, was established. Numerical simulation of the surface grinding temperature field of a nano-ZrO 2 dental ceramic workpiece material was conducted. With increased cut depth, the peak values of grinding temperature rocketed. With increased workpiece feed speed, grinding temperature on the finished surface decreased. With increased wheel peripheral speed, a high amount of heat energy accumulated on the surface because of the low heat-transfer coefficient of the ceramic material, and a large temperature gradient appeared in the temperature distribution layer. Under the same cooling and lubrication conditions, grinding temperature insignificantly changed along the direction of grinding width. Conversely, under different cooling conditions, the temperature variation was significant. MQL grinding conditions with additive nanoparticles significantly affected the weakening of temperature effect on the grinding zone.Keywords: grinding; temperature field; nano-ZrO 2 dental ceramics; nanoparticle jet; minimum quantity lubrication; MQL.Reference to this paper should be made as follows: Wang, S., Li, C., Jia, D.

The results showed that, compared with the other two flood cooling methodology conditions, MQL provided effective lubrication, yet insufficient cooling effect.…”

In this research, the heat transfer model of surface grinding temperature field with nanoparticle jet flow of MQL as well as the proportionality coefficient model of energy input workpiece was established, respectively. The numerical simulation of surface grinding temperature field of three workpiece materials was conducted. The results present that, in the workpiece, the surface temperature was significantly higher than the subsurface temperature, presenting relatively large temperature gradient along the direction of workpiece thickness. The impact of the grinding depth on grinding temperature was significant. With the increase of the cut depth, peak values of the grinding temperature rocketed. Distribution rules of the temperature field of 2Cr13 in four cooling and lubrication approaches were the same. Based on the excellent heat transfer property of nanofluids, the output heat through the grinding medium acquired an increasingly high proportion, leading to the drop of the temperature in the grinding zone. For the same cooling and lubrication conditions, grinding temperature presented insignificant changes along the direction of grinding width. Yet, under different cooling conditions, the temperature variation was significant. MQL grinding conditions with additive nanoparticles demonstrated great impact on the weakening of temperature effect on the grinding zone.
