Abstract
A method of grinding crankpin journals on a crankshaft in which the crankshaft is rotated about its central longitudinal axis. Abrasive belts are moved along paths substantially perpendicular to the crankshaft such that the abrasive surfaces of the belts grind the crankpin journals while the crankshaft rotates. The belts are guided independently of one another at the point of contact with the crankpin journals along a variable path according to the position of the crankpin journal around the central longitudinal axis of the crankshaft as the crankshaft rotates.
