Study on Small Down-feed Grinding Using Inert Gas Supplied out Wheel-Possibility as a way of the finishing grinding by a conventional wheel-

In this study, "New Grinding Method Using Inert Gas Supplied out Wheel" that controlled chemical reaction occurring between grains and a workpiece in grinding process which was a factor of the wheel wear was devised.Experimental evaluations to foresee the possibility that new processing to grind the carbon steels should made the more effective finishing way in grinding processing carried out the following results. (1) Suppressed attrition wear of the cutting edge of the grain in the case of the new grinding using inert gas supplied out wheel has brought out the good cutting ability of the grain. (2) The amount of the minimum stock removal in grinding with the new method was larger than that in the atmosphere grinding. The minimum grounded depth of the workpiece obtained by one pass grinding was as about 0.3μ m to the given 0.5μ m down feed for a conventional Al 2O3 wheel. (3) The surface roughness of the workpiece obtained in the case of the new grinding was also more superior than that in the atmosphere grinding. (4) The new grinding method showed the better performance in comparison with that in the atmosphere grinding.
