workpiece prevented use of the full rotational speed capability of the Steadyline bar, machining
time in the operation was reduced from 12 hours to 2 hours (more than 80 percent) with use of
the Steadyline passive/dynamic vibration-control system.
Demonstrating the Steadyline system’s benefits in a side milling operation, a Combimaster
milling cutter holder without passive/dynamic vibration control was applied with a 20 mm
diameter cutter at 312 m/min and 0.3 mm/tooth feed rate at a cutting depth of 0.9 mm in
1.1206 CK50 steel. When a version of the same tool employing the Steadyline system was
applied at the same cutting speed and feed as the undamped version, it was possible to increase
cutting depth to 2.2 mm (an increase of 2.3 times) without unwanted vibration.
