Influence of Dressing Conditions of Grinding Wheel on Grinding Fluid Performance in Free Infeed Plunge Grinding

Abstract

The influence of dressing condition of a grinding wheel on the grinding fluid performance was investigated experimentally in free infeed plunge grinding. The results can be summarized as follows : The effects of the emulsifier of additive concentrations in emulsion type grinding fluids on the rate of stock removal and the grinding ratio vary markedly with the dressing conditions such as dressing speed and sharpness of the dresser, which govern the character of the dressed wheel surface. Every grinding fluid has an optimum fluid concentration for the best grindability obtainable with a definite grinding wheel, the optimum concentration being shifted to a higher value by increasing the dressing speed or sharpness of the dresser. When free infeed plunge grinding is applied for the evaluation of the performances of fluids, the test results should be examined in due consideration of the dressing conditions.
