Product Details
Resin CBN grinding wheel, CBN (Cubic Boron Nitride) grinding wheels are specially used for gear hob cutter grinding. CBN (Cubic Boron Nitride) due to its hardness, thermal resistance which is higher than diamond's, allowing work at 1,900°C (3,500°F), and the good chemical resistance of CBN to ferrous alloys. The roughness and sharpness is the most important for the CBN wheels.
