Abstract
Continued from the previous report on centerless grinding of alusil, this paper discusses the surface grinding of alusil. Eleven sorts of grains in GC- and WA-systems were used for grinding wheels and the optimum conditions for the grinding were researched with respect to the observation of ground surfaces.
The results obtained were as follows.
It seemed that WA-wheel gave better ground surface of alusil than GC-wheel, and well ground surface was obtained when the grain size of abrasives was rather rough and the grade of wheel was low. The ground surface with good appearance showed comparatively high value of NF-roughness. In general, the surface was better when the depth of grinding was smaller and the feeding velocity on the table was higher. In the range of these experiments, WA46.31-wheel gave the best results, and WA60H-, WA80K- wheels, etc. also gave comparatively good results.
