Abstract: A broaching machine and method for machining main bearings and crankpin bearings on a crankshaft for an automotive engine wherein a plurality of removable cutting tool inserts are arranged on a horizontally reciprocating slide below a rotating crankshaft to machine a plurality of bearings and distribute machining forces over the machining operation during a single pass of the slide. The slide also serves as a transfer device for loading and unloading crankshafts into the machine. An air bearing can be developed between the slide and the tooling to assist the operator in removing the tooling from the slide.
