Haas Automation introduced its Servo Bar 300 bar feeder in 1999 and has launched the all new Haas Bar Feeder for what the company describes as a simpler and more affordable way to automate part production on Haas turning centres.
Designed and built by Haas Automation exclusively for use on Haas ST-10 through ST-35 and DS series CNC turning centers, the Haas Bar Feeder connects directly to the Haas control, and is powered by the turning center.
Fast set up and quick changeovers are what sets the new Haas Bar Feeder apart from the competition. It features an innovative rollaway design that provides easy access to the rear of the lathe spindle for quick liner adapter and liner changes. Simply press the foot-pedal release, and the bar feeder easily rolls out of the way for access. 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 visual “on-center” adjustments.
Quick-change pushrods snap into place without tools, and both sizes store conveniently 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 new belt-driven bar-shuttle system that is 7 times faster than the previous version, with lightning-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.
