Study on Lubricating and Cooling Effects of Several Cooling Systems Used in Face Grinding
We observed that the lubrication effect is greater than the cooling effect for decreasing the friction heat in face grinding. It was clarified that cool-air grinding is difficult to apply to face grinding under the present grinding conditions. We could obtain the minimum ground surface roughness (hereafter noted as surface roughness) at a mist suppｌy volume of 15 to 30ml/h in mist grinding. The largest stock removal rate (hereafter noted as grinding efficiency) is obtained in mist grinding. However, grinding efficient was small in cool-air mist grinding, by which a large cooling effect of cool air was expected. Though mist and cool-air mist grinding perform similar to wet grinding in few grinding passes, wet grinding is properly applied by large chip removal action in many grinding passes.
