What are the Machining Processes for Camshafts?

The machining processes for camshafts mainly include three stages: rough machining, finish machining, and surface treatment.

Camshaft rough machining typically employs methods such as turning and milling to process the blank into a basic shape close to the finished product.

The camshaft finish machining stage involves processes such as grinding and honing to ensure the dimensional accuracy and surface finish of key parts such as cams and journals.

In terms of camshaft surface treatment, commonly used heat treatment processes include high-frequency quenching, carburizing, and nitriding to improve the hardness and wear resistance of the camshaft.

In addition, surface polishing and rust prevention treatments are performed to extend service life and improve operational stability.
