초록
An experimental investigation on the wear of alumina grinding wheel is presented. The experiments consist of the measurements of fracture strength of the abrasive grains, grinding forces, and the area of wear flats of grinding wheels. Microscopic examinations of abrasive grains were also carried out to observe the progress of wheel wear. the results show that the 32A grain, which has relatively lower fracture strength, wears out faster than 5SS and 5SG. The wheel wear occurs much faster in wet grinding than in dry grinding. It has also been found that the grinding forces increase logarithmically with increasing wear flats.
