Resin bonded grinding wheel containing gas-filled thermoplastic resin
beads and method of making it
An improved process is disclosed for making grinding wheels wherein a vinyl
resin, such as polystyrene, or other suitable thermoplastic material is
incorporated in the refractory composition with an epoxy binder or other
binder which cures in the proper temperature range. The flat surface
grinding wheels made in accordance with the invention and used on
double-disc grinders function more effectively and facilitate rapid
grinding and their useful life can be increased at least 3 or 4 times.
