The Super Hydrobar HS is a versatile manual bar feeder engineered to deliver reliable, vibration‑free barstock feeding for small and medium production runs. The feeder supports a broad diameter range from 2 to 68 mm, and bar lengths up to 6000 mm, making it suitable for a wide variety of turning applications — from camshaft‑controlled screw machines to Swiss‑style CNC lathes.

At the heart of the design is the use of the proprietary Hydrobar® technology, which relies on hydrodynamic support within completely enclosed guide tubes. As the bar rotates, an oil film forms between the bar and the guide tube, lifting the bar off the tube walls and providing “cushioned,” vibration‑free support. This ensures smooth feeding, superior surface finish, tighter tolerances, and extended tool life — even at high spindle speeds.

The Super Hydrobar HS uses a radial arrangement of multiple guide tubes — typically in three- or six‑tube configurations — clamped securely on a common pitch circle. Each tube has its own piston/pushrod assembly, driven by hydraulic oil pressure, which pushes the barstock into the lathe spindle. This tube‑by‑tube design greatly simplifies setup and maintenance.

Loading new bars is straightforward thanks to the “tube swing‑out” loading system. Operators can pivot a guide tube out to load stock, then pivot it back into place. The feeder supports loading from either the right or left side, depending on shop layout, and works with both fixed‑headstock and sliding‑headstock lathes.

One of the major advantages of the Super Hydrobar HS is its exceptionally fast diameter changeover: by simply indexing the guide‑tube ring to the appropriate tube and coupling, a new diameter can be set in under a minute. This quick‑change capability reduces downtime and helps keep production running smoothly.

In practice, that means shops get a manually controlled bar feeding system that behaves with the precision and stability of an automated feeder — delivering high accuracy, excellent surface finish, minimal vibration, and broad flexibility across bar diameters and lengths. For manufacturers running frequent smaller‑ to medium‑volume jobs, the Super Hydrobar HS offers a cost-effective feed solution without sacrificing quality or performance.
