(1) casting using ductile iron casting axis, such as crankshaft, camshaft, etc., mainly USES the normalizing heat treatment processing, in order to improve the axial mechanical properties of quenched and tempered, or may be adopted for surface hardening after normalizing and isothermal quenching process. Ductile iron shaft and forging steel shaft treated by the carbonitriding, the fatigue limit and abrasion resistance increased significantly, compared with forged steel shaft is different and the proceeds from the carbonitriding layer, hardness is taller. Made in nodular cast iron crankshaft, general manufacturing process route as follows:

Casting and normalizing ten high temperature tempering (or normalizing) to straightening to clean up, rough machining, to stress the annealing heat treatment and surface - straightening - finish machining.

(2) casting forging forming the deficiency of the axis of the biggest is its low toughness, when overload or the big shock loading, easy to brittle fracture. Therefore, for shaft strength as the design basis, mostly USES the forging forming. Forging forming in the axis of the commonly used material for medium carbon steel or carbon alloy quenched and tempered steel, forged this kind of material with good performance, with the appropriate heat treatment after forging, can obtain good comprehensive performance, high fatigue strength and wear resistance, effectively improve the ability of shaft resistance to deformation, fracture and wear. According to the shape of the axis of the need to design, combining with the production equipment, production batch, for shaft shape is simple, free forging forming technology, can be used for mass production of complex shape of shaft, is given priority to with model forging. The manufacturing process route is commonly:

Blanking to forging to normalizing, rough machining, conditioning and finish turning to surface quenching and low temperature tempering, grinding.
