"Part holding. One way GKN Aerospace has found to minimize fixture problems is to make tapped holes in sections of the part that will later be cut away. These holes are used to bolt the part to the worktable [using Invert-A-Bolt™ fasteners]. Since the bolt comes from behind the part, there is nothing on the part's surface to block the spindle's path. The cutter can reach five sides of the part, and only a single setup is needed."

"The fixture is working great!! No problems so far... The plate indicated across the bushings as close as you are going to check. The I29 hole is closer than you are going to check on the machine...What I meant to say was that the fixture could not have been built more accurately. Do not change a thing tolerance wise. Everything is just fine. "

"...the invert-a-bolt fixture is working excellent on our Makino A88 machine. We have even added one of our own...We use the inverta-bolt [fasteners] in our work holding scheme as often as possible....We have not done any real time study as far as savings on our IVB plate. However I am sure the numbers would look real good if they were calculated...."

Tech Manufacturing, Inc.
"If your customers are looking for good, consistent clamping, or they are high-speed machining, where you have to be careful how to remove the material; if they have fixture management problems, or simply need a unique holding solution where having the ability to machine right over the top of these things or tuck them in close to the part is required, then I heartily recommend the use of Invert-A-Bolt™ fasteners."

VersaForm/ LMI Aerospace, Inc.
"The quick change invert-a-bolt project is working like a charm. The invert-a-bolts are working as planned and the operator is really happy with the setup. We are just starting the second phase of the project, of adding the roller table function, but I don’t anticipate any issues with the invert-a-bolts based on our testing and design to date. I’ll send some pictures when we get the completed roller table in place. Your product has worked as advertized, is meeting our hold-down and change out requirements and no mechanical or maintenance issues to date (probably why you haven’t heard from us).

Thanks again for all your help to date and keep rolling out the great quick change products!"

[The fixture is] "working out pretty good, really!...
The bosses like it and are intrigued by it."

"Our setups used to take 2 hours. With your modular fixtures it only takes 20 minutes or so....

"Yes, we received the aluminum T/S [Tombstone] and T-Slot vises last week and they look very good.  We have the T/S up on the second pallet on the MAG1 and will indicate it ASAP and let you know how it comes out. You all do nice work…Wink"

Focus: Hope Manufacturing
"... The first invert a bolts have been used and the personnel on the floor love them. The numbers have already sold the big cheese. Our efficiency [on this job] went from 47 to 89 percent the moment we installed the invert a bolts..."

"The minute we started using the Invert-A-Bolt™ fasteners we solved our flatness and parallelity problems. We were finally able to make the part to spec."

"Increases workholding flexibility on the machine."

Beechcraft/ Hawker Beechcraft/ Raytheon Aircraft
"...And, while these results are impressive, Raytheon Aircraft quickly realized the efficiencies high-speed machining passed on to the rest of the manufacturing process...'we consolidated tooling and eliminated other operations. By using simplified, standardized tooling, maintenance decreases and impacts overall part quality and setup time.' Raytheon Aircraft's approach to workholding also impacts setup, using what it refers to as a universal vacuum fixturing...this standardized approach to vacuum fixtures allows operators to setup smaller parts in one operation. 'The fixturing uses back bolts [Invert-A-Bolt™ fasteners] and a large vacuum to hold the parts...A thin foil web is ultimately cut around the floor of the part -- about .0003 inch of material to keep the part attached to the universal fixture. When machining is complete, the vacuum is released and the part is snapped out of the surrounding material'.... Ultimately Luallen predicts certain applications could employ vacuum-free fixturing, and rely on the material surrounding the part for stability. 'This would drive out more fixturing and we would have one less system to rely on," says Luallen."

"...I'm not sure when invertabolt came out with their version but they work very well. I know at least one company that does almost all of their flat plate work on universal grid plates using these alternating with bushed holes. I believe Invertabolt or sombody else now sells plates similar to these. One of the really great advantages to these things is the small footprint. With practice ( & a little guts) you learn to program cutter paths close to them &, since there is no bolt head, over the top of them. ...

"+1 on the inverta-bolts. It requires some prep work on the block ahead of time, but they work great for window frame machining. Its a great way to hold parts that have no straight walls for clamping."

HM Dunn/ Nex-Tech Aerospace/ Thayer Aerospace
"We've got (2) bolster plates for our SNK high speed 5 axis profiler. Each bolster plate has 640 1/2-13 invert-a-bolts on 4" centers. We load parts on one bolster p[l]ate off-line while the other one is on the machine. On one job we hold an alluminum plate 6" x 58" x 105" The invert-a-bolts work great for us."

Qualtronic/ Euro-Precision
"... I don't know if you can remember but we bought and used some 5/8" invert-a-bolts from yourselves last year. We had great success using them. The part was unbelievably difficult to program but using this work holding allowed me to use one fixture to machine the lot. It took some thinking to work out where to leave the tabs but once done it was easy to machine. The part come out flat to within a 0.0025" which was amazing considering the volume of metal removed ... "   Visit Qualtronic   Greg H.

"I love your product! ... Thanks for being in business... we love products that help us with Lean...."


"We actually use Your product all over our shop, and they work great for us here at Arnold Engineering/Noranco. We use them on 4 out of 8 5-axis machines and 3-axis machines for an array of purposes from holding parts and fixtures to even mounting parts to be checked by our Quality Assurance dept. 100’s of our fixtures use invert-a-bolts for work holding and they do a tremendous job for us. We haven’t had any flaws or problems with your invert-a-bolt system on any machine or fixtures.

Thank you for taking the time to ask us how your product works for us! We still use your products and would be glad to let any company know how great this system is."

Blueswarf - High Speed Machining Optimization Software
"We use Invert-A-Bolt in our demonstration parts. Invert-A-Bolt enables us to machine thin walls and floors without concern of part movement and their low profile allows us to machine most of the workpiece material. The rapid and repeatable changing of parts with Invert-A-Bolt is important to us in trade show and demo environments."   Blueswarf High Speed Machine Optimization Software

"Just completed an industrial course and used Invert-A-Bolt™ system.

Works excellent. Industrial students impressed with simplicity of the system
Finding a metric fine M20x1.5 tap was the only problem.

Made holding plate with matrix of M20 holes and 10mm dowel locations. Snap-off fixturing excellent."
