The Haas bar feeder, which provides a simple way to automate part production on Haas turning centers, features a re-engineered, heavy-duty—yet still compact—design that boosts productivity and streamlines turning operations, the company says.

Designed and built by Haas Automation exclusively for use on Haas ST-10 through ST-35 and DS series CNC turning centers, the bar feeder connects directly to the Haas control and is powered by the turning center.

The Haas bar feeder offers fast setup and quick change-overs. It features a rollaway design that provides easy access to the rear of the lathe spindle for quick liner adapter and liner changes. When pulled back into position, the bar feeder locks into place completely, eliminating accidental bumps or alignment issues. And making bar height adjustments is easier than ever, using a single handwheel right where it’s needed to make “on-center” adjustments. Quick-change pushrods snap into place without tools, and both sizes store in the cover of the bar feeder. Built-in racks on both ends of the bar feeder provide storage for and easy access to all Haas extruded spindle liners, so there’s no need to walk around the machine, as with the previous version.

To reduce cycle times, the Haas bar feeder uses a belt-driven bar-shuttle system that is 7 times faster than the previous version, with fast retract speeds. Optical sensors accurately determine bar position, even on bars with chamfers and ragged ends, and stainless steel runners on the charging tray help bars roll down to the loading area much easier. Even square and hexagonal stock glide down smoothly to the new bar feeder tray.

Because it’s integrated with the Haas control, all bar feeder parameters are set directly at the lathe. Easy-to-read, on-screen icons indicate if the bar feeder is out of position, has the lid open or needs to be latched back into place.
