The Mini-Rhinobar features a feed tube extension that supports bar stock to eliminate vibration and improve cutting accuracy. That's where the bar feeders come in. At Osteomed, two Citizen L-20 machines are dedicated to titanium screw production. Besides being noisy, the vibration of these bars is transferred to the lathe, where it can spoil the surface finish of manufactured parts. To reduce bar vibration, the Mini-Rhinobar employs hydrodynamics.
Oil fills the gap between bar stock and feed tube, acting as a noise-dampening support.
As the bar begins to turn, hydrodynamic forces move it toward the center of the feed tube, with centering forces increasing as bar speed increases. For additional bar support, the Mini-Rhinobar features a feed tube extension equipped with nonrevolving bushings. Though it operates according to programmed instructions, the Mini-Rhinobar itself requires no programming. So you program the lathe only. You don't have to save programs for the bar-feeder like you do for the lathe.
