GCH-wheels are specifically designed to handle large radii, as well as thrust and plunge grinding common for high-performance crankshafts. Like the GCS-wheel, the GCH-wheel can be used on journals with Rockwell hardness of 35Rc or less. For diesel crankshafts, you need a wheel that can be used on journals with a Rockwell hardness of 35Rc or more.
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.

Most of the time crankshaft thrust faces are difficult to grind. Because, they are done, using the side of the grinding wheel. Consequently, grinding marks left on the crankshaft face; produce a visual swirl or sunburst pattern with scratches. Also, crisscrossing one another in a cross-hatch pattern; similar to hone marks on a cylinder wall.

Directions for crankshaft grinding and polishing. ... Crankshaft journal surfaces should be ground and polished to a surface finish of 15 micro inches roughness average Ra or better. Journals on highly loaded crankshafts such as diesel engines or high performance racing engines require a finish of 10 micro inches Ra or better.
The use of ion-nitriding allows the nitride process to be done subsequent to finish-grinding. The material which is currently viewed as the ultra-extreme crankshaft alloy is a steel available from the French manufacturer Aubert & Duval, known as 32-CrMoV-13 or 32CDV13.

Don't go round the crankshaft. And just use a small stone. I use automotive type 'wet or dry' - it comes in about any grit imaginable. Tear it in a strip that when folded it fits the surface youre working on and with a spray can of WD, or similar, keep it wet. I have a lathe and mount the shaft in it and go at it.
The hydraulic crank press station is strategically located between the welding and grinding stations inside the Ohio Crankshaft facility. This station is filled with fixtures and multiple dial indicators that monitor many points along the length of the crank. Hydraulic pressure is applied to "bend" the crank back to proper tolerances.
