What Is Crankshaft Machining? | Crankshaft Machining
The traditional crankshaft machining process involved turning a crankshaft and bearing journal machining and final grinding. Specifically, each crankpin was turned on a large, sturdy mandrel with the crankpin in the center and the central axis of the crankshaft offsetting half of the crank stroke.

Surface Hardening of Crankshafts
This process diffuses carbon into the surface of a low-carbon steel, increasing its hardenability. This can impart large increases in hardness, with considerable case-depth and an attendant increase in wear-resistance and fatigue strength. However, owing to the harden, quench and temper nature of this treatment, distortion can be a very …
