- Abstract
Due to the enclosed working environment and inadequate cooling, it is easy to produce excessive local temperatures in the double-face grinding machining process. Excessive local temperatures lead to a number of issues, including grinding wheel wear, workpiece burns, and surface quality degradation. In order to reduce the temperature with little coolant, a study on coolant distribution is necessary. This paper studies the effects of grinding wheel speed and workpiece speed on the coolant distribution law. The unidirectional flow field model in double-face grinding is established based on the contact equation of computational fluid dynamics, the Navier‒Stokes equation, and the turbulence equation. This model also considers the pores on the grinding wheel surface, the equivalent height of the abrasive particles, the geometric boundary, and the equivalent gap between the workpiece and the wheel. The results show that the component surface fluid velocity gradually rises from the inner to the outside diameter of the grinding wheel. The grinding area pressure distribution in different parameters is analyzed. The variance analysis of coolant distribution is carried out. It is found that there is a positive linear correlation between the grinding fluid flowing into the grinding zone and the grinding wheel speed. With the increase of wheel speed, the more liquid concentrates on the area where the coolant enters. And it is observed that 60 rad/s wheel speed leads to a more even coolant distribution and a flatter machined surface.
