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.

Centreless grinding of crankshaft bearing journals is in many respects similar to camshaft grinding. The main differences are: Camshafts are rough ground directly from the cast condition, while crankshafts may have to be pre-turned. The diameter tolerances for crankshafts are often even tighter than those for camshafts.
I) Crankshaft grinding is recommended in case of increase in ovality and development of taper in crankpin and main journal. II) Crankshaft grinding is required in case of development of bearing line marks, pitting on the crankpin or crank journal diameter, rough surface, etc.
For these reasons, crank grinders typically allow a 0.020-inch safety factor, so the real obtainable stroke increase from a 0.100-inch journal diameter change is about 0.080 inch.
Onsite Crankshaft Grinding Machine Following is the outline of inspection and repair of main engine crankshaft: I) Inspection of Crankpin/Main Journal: It is important that surface geometry of the crank pin or main journal is thoroughly checked such as roundness defect, loss of alignment, conicity, barrel form, surface finish, etc. RA Power Solutions have inspection formats and all …

For crankshafts which rotate counterclockwise, such as some marine engines, the crankshaft should be chucked at its opposite end during grinding and polishing. This is the same as viewing the crank from the flanged end rather than the nose end in the accompanying figures.

In order to understand the working of the crankshaft grinding wheel, it is important to understand its functionality. The typical crankshaft grinding is a cylindrical grinding of a crank pin or bearing by any form of plunge method. The normal speed of its operation is from 33 to 45 MPS. Quality crankshaft grinding wheel grinds freely, and it generates minimum heat and …
Crankshaft design requires meticulous attention from material selection to the various hardening processes. Each part of the crankshaft is designed to have different hardness meeting specific demands of the application. Grinding of the shoulder region is a surface grinding operation, while the grinding of the pin is a cylindrical grinding ...

CRANKSHAFT grinding & Indexing. When a crankshaft is turned to an undersize, it can and does change the stroke and degrees apart of each rod journal. To index a crank, first the machinist has to know where the stroke and degrees (swing) are. Once this is established, with the right machine to start with, the crankshaft can be indexed for both ...
