In grinding aluminium, the pores of grinding wheels are easily loaded with the fine ground off particles of aluminium. When high accuracy is required of the size and the finished surface of a work, there are many problems as to the grinding conditions concerned with loading phenomena.
In this experiment, Surface Grinder was used. The test specimens of aluminium (IS) were ground by aluminium oxide grain wheels, using various grinding fluids. The amount of loading aluminium, the grinding resistance, and the roughness of the ground surface were measured. Especially, the amount of loaded aluminium on the wheel surface w as estimated by chemical analysis.
As a result, aluminium is able to be ground fairly good by aluminium oxide abrasive grain, if the suitable grinding fluids which have a good boundary lublicating ability for aluminium and alminium oxide are applied. Namely, in the case of suitable grinding fluids, the quantity of loaded aluminium on the aluminium oxide wheel does not increase so evilably. And it is found that the loaded aluminium on wheel has less value in the use of soluble type fluids, and also, the roughness of finished surface largely depends on the degree of loading.
