The Hydrobar Sprint 542 automatic bar loader from LNS America Inc. feeds 12' round, hexagonal or square bar stock with diameters from ¼" to 1-⁵⁄₈" (5mm to 42mm) into fixed- or sliding-headstock turning machines. A programmable, fully automatic, hydrostatic front stabilizer dampens vibrations between the bar feed and the lathe spindle, enabling users to operate at optimal spindle speeds while maintaining cutting accuracy, according to the company. Hydrobar Sprint 542 uses round, elongated guiding elements that open for new bar loading and then close for the entire machining process. This permits hydrodynamic or hydrostatic operation in a pressurized oil film. To further enhance productivity, complete diameter changeovers take less than 8 minutes using quick-change guiding elements that require no tools, and by entering diameter, part length and application data into the prompting remote control. The machine then automatically self-adjusts to these parameters. Standard equipment includes a remnant retraction system, an automatic front stabilizer, a menu-driven, prompting remote control, and a Z-axis retraction system. It can be ordered with either a front- or rear-mounted loading ramp. The loading ramp includes automatic diameter adjustment of bar selection fingers.
