Induction heat treatment is a common method for heat treating different automotive components, including camshafts, which belong to the group of critical engine/powertrain components. Now a new approach makes it possible to induction harden camshafts with almost undetectable distortion.
Ignacio Castro from Arbomex SA de CV commented, “The SHarP-C hardening machine helped us reduce camshaft distortion to 3-5 microns and we have been able to eliminate the entire straightening operation. So, our savings on elimination the straightening operation alone is about $40,000 per year. On top of that there has been substantial improvement of the quality of the hardened camshafts, and our scrap was reduced about 1.5%.”
