Notes
The Hydrobar® Sprint 555 from LNS America, Inc. uses Hydrostatic operation that permits users to cut up to 12’ bar stock at maximum spindle speeds without dangerous vibrations. This vibration reduction produces more precise surface finishes on parts being machined, and extends tool life. The Hydrodynamic principle allows for a wider range of bar stock diameters, fewer guide channels, and 2 – 8-minute changeovers, all of which reduce downtime, improve productivity and support unattended operation.
The bar feed’s Hydrostatic feature uses a patented, self-opening bearing block design that permits users to run round bar stock at a lathe’s maximum spindle speed with or without remnant retract. The Hydrodynamic principle uses an automatic front rest that prevents troublesome bar vibrations from transferring to the machine cutting area throughout the entire diameter range. It also adjusts automatically to the bar and pusher diameters when the operator inputs a bar stock diameter into the remote control.
Sprint 555 reduces the number of guide channels necessary to accommodate the 1/4” – 2-1/8” (5mm – 55mm) range of bar stock diameters, thus requiring fewer changeovers. When a changeover is necessary, a unique quick release system for changing guiding elements greatly reduces changeover times. The quick release feature allows an operator to manually change the guiding channels, without tools, in a matter of seconds.
