The abrasive particles are bonded by a ceramic binder with a uniform proportion, and then pressed, dried, baked and trimmed. The grinding tool has many holes and uses abrasive particles to cut. Abrasive particles expose their sharp corners on the surface as cutting edges. Mainly divided into: ceramic grinding wheels (silicon carbide, brown corundum, white corundum, etc. ) and ceramic superhard grinding wheels (ceramic bonded diamond grinding wheel and ceramic bonded CBN grinding wheel).
