ABSTRACT:
A lathe for simultaneously machining the line bearings of a crankshaft is provided with a turret shaft rotatably mounted on a cross slide for rotation about an axis parallel to the spindle axis. This shaft carries a plurality of turrets each turret being provided with a set of cutting tools on its periphery and being fixed to the turret shaft. Upon withdrawal of the turrets from the workpiece the turret shaft can be indexed to thereby bring the next set of tools into position preparatory to the inward feed of the turret shaft for engagement of the tools with the crankshaft. Two sets of such turrets can be provided on opposite sides of the spindle axis for simultaneous cutting operation on opposite sides of each line bearing of the crankshaft.
