The efficancy of the grinding fluid in prevention of the loading was studied for following workmaterials, i. e. commercial pure aluminum and aluminum alloys of AC2A-F, AC3A-F and ACBA-T6, which cause the loading in dry grinding. Coating of a small quantity of lubricative oil on the workpiece surface is considerably effective in prevention of occurrence and growth of the loading. Application of lubricative oil with the nozzle being held about 0.3mm distant from the grinding wheel is very useful for prevention of occurrence and growth of the loading, and a good surface is obtained for AC2A-F, AC3A-F and ACBA-T6. The cooling action of the grinding fluid is little useful for prevention of the loading. The washing action of fluid jet is not always useful for prevention of the loading. Its effectiveness seems to depend on the adhesion strength of chips to the cutting edges of abrasive grains.
