Rhinobar® systems are designed for use with all types of CNC lathes and are ideal for dedicated production jobs. The Rhinobar® operates on the hydrodynamic principle of supporting the bar stock in an oil bath. Oil fills the gap between the bar stock and feed tube and as the bar begins to turn, hydrodynamic forces move it toward center of the feed tube. Centering forces are amplified as bar speed increases. Feed tubes are available in graduated sizes to minimize the bar to feed tube clearance In order to achieve maximum operating speeds.
