Through advanced design and manufacturing techniques, the heavy-duty LNS Hydrobar Sprint 552 and 565 bar feeds provide increased stability while reducing bar vibration, according to the company. As a result, these bar feeds improve productivity by enabling increased machine spindle rpm, improving surface finish and extending tool life. They also provide all of the technology the Sprint 555 offers.

The model 552 accepts barstock diameters from 1/4" to 2" (5 mm to 52 mm). The model 565 accepts barstock from 1/4" to 2 5/8" (5 mm to 65 mm). Both units operate with fixed or sliding headstock machines and are the only bar feeds that can operate in either hydrodynamic or hydrostatic  modes. Hydrostatic operation permits users to cut as much as 12" barstock at optimum spindle speeds without harmful vibrations. The hydrodynamic principle allows for a wider range of barstock diameters, fewer guiding elements and 2- to 8-minute change-overs, all of which reduce downtime, improve productivity and support untended operation.

The Sprint 552 and 565 bar feeds include many other features such as remnant disposal through the lathe or through the bar feed; no manual intervention for the bar feed selection and front stabilizer adjustments; servodriven, automatic torque and speed according to bar diameter; and easy set ups through a menu-driven prompting remote control.
