Crankshaft Grinding

For crankshafts, the market requires an operational performance of up to 1,000.000km. To achieve the desired endurance and strength, high surface quality and precision ground journal geometries are necessary. Thus, vitrified bonded CBN grinding wheels are widely used in the grinding of crankshaft pin and journals.
