Abstract
A roller cutter module for use with a rotatable tool carrier head of a lathe machine tool includes multiple opposed cutter wheels for transversely cutting tubular workpieces, and wherein the wheels are rotatably mounted upon support arms that are pivotally attached to a support plate that is attached to the tool carrier head. An actuating system carried by the support plate pivots the support arms so as to cause the cutter wheels to be fed radially inwardly to sever a workpiece. The actuating system includes a linkage assembly which cooperates with the support plate to enable equalization of the cutting forces applied by the opposed cutter wheels to an out-of-round workpiece. The cutter wheels are mounted on the support arms so as to biased against spring elements in an axial direction to track a cutting centerline axially away from the support plate.
