Gear Hob Sharpening
CBN grinding wheel are 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.
