Camshaft grinding with EHWA CBN grinding wheels

The camshaft controls the intake and exhaust valves of a reciprocating engine with the help of mechanical stroke movements. Nowadays, camshafts are made of cast iron and sometimes forged steel. Due to the high mechanical load, these components are surface-hardened.

The high surface hardness poses a major challenge for economical grinding processes. EHWA has taken on this challenge and developed a special bond for the economical grinding of camshafts. The EHWA specification showed an up to 18% higher stock removal rate with high dimensional stability and high surface quality compared to the competition.
