ABSTRACT:
A gear cutting machine is provided with an endless chain for carrying a plurality of tools into contact with one or more workpieces to thereby form gear tooth configurations on the workpieces. The endless chain is pressed into firm contact with a first series of rollers in the zone in which its tools make contact with a workpiece to thereby prevent unwanted deflections of the endless chain and its tools relative to the workpiece. A second series of rollers prevents side-to-side deflections of the endless chain in the work zone.
