JSC "Volzhsky Abrasive Plant" Kumi-Murugappa Group Documentation Abrasive tool The tool is designed for abrasive processing, in which abrasive grain with grain size F16-F220 is used as cutting elements, firmly bound by a binder-bond: ceramic and bakelite. The tool is made of fused alumina and silicon carbide materials. Circles - bodies of revolution, are mounted on the spindle of the grinding machine; have a through cylindrical hole. Small diameter wheels are used for grinding holes. The segments are clamped in the sockets of the chuck. After being fixed on the machine, the segments form an intermittent flat annular surface for vibration processing. Abrasive bodies for vibration processing - "tumbling" are used for vibration treatment of parts in drums and vibration machines. The tool is available in hardness FZ. The hardness of the wheels depends on the grinding operation.
