Effects of the Characteristics of Grinding Fluids on the Fracture of Abrasives during the Grinding Process.

For better grinding performance, three significant aspects involved, namely, the grinder, the grinding wheel and the grinding fluid, must be improved together and brought to a required level. This paper attempts to clarify the effects of the grinding fluid additives on the grinding performance by using a three-face Makitsuke nozzle which ensured a supply of fluid directly to the grinding point and observing specifically the fracture behavior of abrasives during grinding. As a result, a higher grinding ratio and better surface roughness were obtained with reduced grinding resistance and wheel edge wear.
