A grinding system for grinding the crankpins on a crankshaft having an even plurality of symmetrically spaced pins comprising a number of cylindrical grinding machines equal to half the plurality of pins each for grinding a single pin located at a distinct radial and axial position, apparatus for depositing a crankshaft at a selected start location, apparatus for displacing the crankshaft from the selected start location sequentially to each of the grinding machines and to an end location so that half of the pins will be ground, apparatus for transferring the crankshaft, with half of its pins ground, from the end location to the start location and for turning the crankshaft end for end so that the crankshaft will be again displaced by the displacing apparatus sequentially to the grinding machines so that the remaining half of the pins will be ground.
