The camshaft is one of the key parts of the engine. The hardness of the camshaft lobe and the depth of the white layer are the key technical indicators that determine the service life of the camshaft and the efficiency of the engine. Under the premise of ensuring that the cam has a sufficiently high hardness and a fairly deep white layer, it should also be considered that the journal does not have higher carbides, so that it has better cutting performance.
The following camshaft wholesalers, camshaft manufacturers and camshaft brand companies will talk about camshaft production technology.
The main methods of producing camshafts at home and abroad are as follows: After cutting the steel forging blank, the process of forming the martensitic layer by high-frequency quenching at the tip of the cam.
At the end of the 1970s, Germany and France successively developed a new process of camshaft argon arc remelting; another hardenable cast iron camshaft mainly in the United States; chilled cast iron camshaft mainly in Japan and France; and camshaft The production process of casting surface alloying with Cr-Mn-Mo alloy coating on parts, etc.
