“…If the distance is too large, most of the fluid will be concentrated near the spray axis and only a small quantity will be left in the outer region (Tawakoli et al, 2010). When the nozzle tip distance from tool tip was kept 10 mm, obstruction of chip flow with nozzle was observed so the minimum distance to start with was selected as 15 mm.…”

“…Lubricants attach onto the finished surface of a workpiece, forming a layer of protective film and serving as lubrication (Brinksmeier et al, 2010;Wegener et al, 2011). This technology integrates the advantages of flood cooling grinding and dry grinding, presenting lubrication effects similar to those of traditional flood cooling grinding (Oliveira et al, 2009;Hadad and Sadeghi, 2012;Tawakoli et al, 2010;Kalita et al, 2012a). Lubricants adopt vegetable oil as the alkyl ester of base oil, which have the features of excellent biodegradability, good lubricating properties, high viscosity index, low volatility, recycling, short production cycle, and insignificant environmental diffusion.…”

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.

“…There are many advantages when using MQL. Effective lubrication reduces the cutting force and temperature, improves wheel life, good surface finish at high cutting speed, reduce or eliminate breathing and skin related problem and at the same time saving the lubricant cost [3,4]. The objective of this study is to investigate the grinding performance of MQL which compared with flood grinding in terms of temperature, grinding force, and specific energy.…”

Abstract. Grinding is one of the most difficult processes in machining operations. Normally, the flood coolant method was used as a cooling agent in the grinding process. The most common defects using flood coolant are higher grinding friction, higher heat generation, and thermal damage. Therefore, the minimum quality lubricant (MQL) was introduced to minimize the defects. The main objective of this project is to compare the performance of MQL and flood coolant techniques in terms of grinding temperature, grinding force and specific energy. Three levels of cutting speeds, three levels of feed rate and depth of cut are adopted in the evaluation. The experiments were conducted on a thin plate of mild steel AISI 1020. The result shows that the MQL technique was effectively supplied to the grinding contact zone. This research revealed that the MQL technique exhibited an advantages on the surface temperature compared to the flood coolant.
