This machine was a complete rebuild of a Fellows 60-15. We converted the mechanical machine into a 5 axis fully CNC controlled machine, X (infeed), B (cutter rotation), C (table rotation), Z (elevation and stroke), X2 (Backoff Cam). We removed the entire mechanical drive train for the stroking motion and installed a 2000Nm Siemens torque motor on the rocker shaft to directly control the up/down stroke motion. This allowed us to implement independent feed rates for the down stroke and up stroke. It was a huge cycle time savings for the customer by allowing a full speed upstroke and slow cutting down stroke. Also the torque motor concept allowed us to have a programmable elevation, which saved time in doing internal gears. The controls we installed were Siemens 840D with PCU 50 front end and our custom conversational gear shaping program.
