<p>The apparatus for making out-of-round workpieces includes a pivoting follower arm in which the pivot is positioned between the cam follower and the cutting tool. A tension spring is connected to the follower arm at a position on the cutting tool side of the pivot, and preferably between the cutting tool and the pivot. The follower arm is made from a lightweight material such as aluminum, and is substantially smaller than the high mass, high inertia prior art follower arms. The apparatus results in substantially increased production speed and reduced wear on the cam follower and the pivot bearing.</p> |
