 12X8 THRUFEED GRINDER

12x8

Thrufeed

Bar stock – from the basic tp Superalloys, holding .0002″ tolerance over 12′ length. This machine is built for it.

Bar stock grinding isn’t glamorous. It just needs to be done. The 12×8 Thrufeed handles diameters up to 1.5″, holds .0002″ over bar length, and matches the grinding wheel specification to the material, material making particularly hard to achieve finishes possible. This machine is a workhorse and gets the job done.

Manual or Full

BAR STOCK GRINDING CAN BE MANUAL OR SEMI-AUTOMATIC, WHICH PACES THE OPERATOR, OR A FULLY AUTOMATIC APPROACH – LOAD UP A FEW TONS OF BARS AND WALK AWAY!

30-Minute Changes

GRINDING WHEEL CHANGES ARE QUICK AND EASY. MATCH THE WHEEL TO THE JOB FOR OPTIMAL TOLERANCE AND FINISH OUTCOME.

4000 Pounds

WEIGHING IN AT 4,000 POUNDS AND xxxx OF STATIC STIFFNESS, THIS MACHINE MAKES FOR A COMPACT MACHINE PLATFORM THAT DELIVERS.

4-8-12-16 Lengths

ONE SYSTEM SIZE DOES NOT FIT ALL. WE CAN FEED BARS DOWN TO 1/4′ DIAMETER AND UP TO 1.5′. WANT TO GRIND EVEN SMALLER? WE HAVE A SOLUTION – JUST ASK!

 THE SOLUTION FOR YOUR CHALLENGE

WHEN BAR STOCK JUST HAS TO BE GROUND

THIS MACHINE GETS IT DONE.

You’re grinding bar stock in volume and need consistent diameter over length.

The 12×8 holds .0002″ over the full bar length. The 8″ wide wheel means more material per pass and stable, consistent results.

Your materials are tough.

The larger width wheel gives you the surface area to match the wheel spec to the material, including superalloys that wear out smaller wheels quickly.

Outboard supports manual, semi or fully-automatic systems.

Rigid outboard supports provide a solid foundation for the bars as they are being ground. 


 TECHNICAL SPECS

BUILT TO A DIFFERENT STANDARD

WHEEL SIZE

12″ x 8″

12″ diameter x 8″ wide grinding wheel, 8″ diameter x 8″ wide regulating wheel

OUTBOARD BEARING DESIGN

Extremely Rigid

Outboard bearing on grinding wheel for high rigidity and high stock removal rates on hard materials

HIGH VOLUME FEEDING CASE STUDY

8,000 PPM

Bar feeders and step feeders compatible. One application achieved 8,000 parts per minute on a 1.5″ long part. Ask to see the video, its pretty cool!

RAM BED TRAVEL

5″

5″ of ram bed travel allowing for removal of grinding wheel without breaking the set-up. Jog the ram back, then jog it forward. Simple!


 WHAT SETS IT APART

THE HIGHLIGHTS

Consistent diameter control from end to end. Bar grinding at this tolerance is production-ready, not a best-case result.

Wheel width enables proper specification matching for difficult materials. Superalloys, stainless, tool steel — the wheel can be spec’d for it.

Supports are fixed square and lock in place. Setup is repeatable and fast.

Optional auto loader keeps bars flowing without constant operator attention. Pairs well with lights-out production environments.

The wider contact area removes more material per pass compared to a 4″ wide wheel. Fewer passes, higher throughput.
