Journals wear over time. They may develop a rough surface, or become out-of-round or tapered. In these cases their surface can be restored in a process called crankshaft grinding. When a crankshaft is ground its journals will be reduced in diameter and so oversized, thicker bearings will need to be installed.
The units are mainly deploying the old-fashioned turning process for machining of the pin and web portions in a crankshaft. This requires multiple set-ups of the component in the machine. In the process, crankshafts have to be loaded on different machines with special work holding fixtures to complete the machining task.
