Grinding a crankshaft is a process of removing material from the journals in an effort to refurbish and reuse an expensive, yet vital component of an engine. It is usually done during the process of rebuilding an engine when needed, but also has some performance aspects which come along with the process.
A crankshaft will need grinding should the crank journals get out of round, tapered or scored as the oil film will not form properly. Precision is curtail when grinding a crankshaft and our perfectionist machinists will grind your crankshafts to within 1/10,000th of an inch tolerances, less than half that of manufacturer specifications.
A racing crankshaft isn’t necessarily a disposable component As seen in Drag Racing Scene magazine. Racing cranks adhere to the tightest tolerances.

A crankshaft includes a crank journal and a crank pin eccentric to the crank journal. An outer circumferential surface of the crank pin is ground by rotating the crankshaft around a central axis of the crank journal and moving a grinding wheel, facing the crank pin, in the diametric direction of the crankshaft according to the rotation phase angle of the crankshaft.
The use of 3D machined surfaces, courtesy of modern CNC machining processes, opens the door to more complex shapes being used, and for the crankshaft designer to design lighter crankshafts which (with some thought put into the design and analysis process) can be more resistant to fatigue failure.
