» Centerless grinding of cam and crankshafts

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. A crankshaft is considerably heavier than a camshaft. Even for centreless ...
