Abstract
In this work, to reduce the harmful effects of the increasing the heat on the surfaces of the ground parts, a new innovative method for lubrication and cooling of the flat grinding process named indirect cooling method (ICG) was studied. To investigate the benefits of this method, M200 and CK45 steels with indirect cooling method and minimum quantity lubricant (MQL) with different cooling rates (15 and 40 cc/s) at different temperatures (-10, 0, and 25 °C) were ground with different cutting depths (0.005, 0.01, 0.02, and 0.03 mm). Other grinding parameters such as the speed of the wheel and the speed of the longitudinal and transverse movement of the workbench was considered constant in each test. The surface roughness, surface hardness (in terms of Rockwell C), and microstructural evaluations (using scanning electron microscopy) were examined. The results indicated that in M200 steel, the indirect cooling method compared to the minimum quantity lubricant, leading to an increase in surface roughness of about 31.81% and an increase in surface hardness of about 2.96%, and for CK45 steel, an increase in surface roughness of about 31.7% and an increase in surface hardness of about 3.11%. The microstructure of M200 and CK45 steels after grinding with both cooling methods is upper and lower bainite and ferrite-pearlite respectively, which are effective on the surface roughness and hardness. In addition, the indirect cooling method is more suitable for CK45 steel.
