It was found in the previous report that the elastic deformation of contact wheel performs a significant role in belt grinding. This paper deals with the effect on the wear process of coated abrasive belts. The contact-wheel surface. grinding was carried out at a fixed infeed, and the changes of belt wear rate and surface topography with grinding time were investigated. Grinding force pulses from individual cutting edges were also observed in a fixed part on the belt surface. The force pulses were obtained by lengthwise grinding of a very narrow workpiece attached to a high-frequency dynamometer. Detail investigations of the change of them with time made clear the rise and fall process of the cutting edges. The results revealed that the wear property is influenced by the contact wheel hardness. With a harder contact wheel the change from old to new cutting edges is smooth and prosperous. On the contrary, too soft a contact wheel brings about flattening or dulling of cutting edges and accounts for the glazed appearance of abrasive belt.
