What is camshaft?

2022-06-16

 The camshaft is a component in a piston engine. Its function is to control the valve opening and closing action.

Materials: Camshafts are usually forged from high quality carbon steel or alloy steel, and can also be cast in alloyed or ductile iron. The journal and CAM working surface are polished after heat treatment.

Position: camshaft position has three types: lower, middle and upper.

Production technology: camshaft is one of the key parts of engine, the hardness of camshaft peach-tip part and the depth of white hole layer are the key technical indexes to determine the service life of camshaft and engine efficiency. On the premise that the CAM has high enough hardness and quite deep white mouth layer, it should also be considered that the journal does not have high carbide, so that it has better cutting performance.
