  1. Fine Detail Cutting for the University of Texas!

    Leave a Comment

    We want to show you a cool part we just waterjet cut that really showcases one of the big advantages of waterjet cutting. This part was cut for the PMC lab at the University of Texas. The material is 1-3/4″ thick 7075 aluminum, and the ribs of this delicate lattice structure are only 1mm (.039″) wide! The through holes in the corners are only .130″ in diameter. This is a somewhat challenging job for even a waterjet, but it would be much more difficult or impossible to accomplish with nearly any other cutting or machining process.

    Most other cutting and machining processes involve a considerable amount of heat and/or force to shape the workpiece. Both heat and mechanical force are a big problem when you’re removing most of the material and producing a very delicate part. A waterjet leaves a cut surface that is unaffected by mechanical stresses or heat, making it ideal for cutting jobs with delicate features and fine detail.

    Talking about the forces involved in a waterjet cut, we have some quick facts that we think you’ll find interesting. The same exact waterjet that we’ve used to cut metals up to a foot and a half thick exerts a mere 22 pounds of downforce on the workpiece during a pierce and less than 5 pounds of downforce during the cut! And yes, we do actually know this to be true. We literally pierced and cut material that was supported by a postage scale so that we wouldn’t have to lie awake at night anymore with such weighty questions on our minds…

  2. Check Out Our New Toy!

    If you attended our Open House, then you already saw our latest waterjet. You were even lucky enough to watch it snorting through 9” thick steel!

    We’re especially excited to make this announcement to all of our customers, and here’s the big reason… While this new machine is 5-axis and 87,000 psi just like our other machines, it is much larger than the others. The cutting envelope is 3 meters x 7 meters (for those of you who deal with high blood pressure whenever you’re given dimensions in metric, that is about 118” x 275”). So we can easily put a full 8’ x 20’ plate on the table and have plenty of room to spare!

    You may have noticed that we’re giving you the X and Y travel on this machine, but not the Z. There’s a simple reason for that. We’re not accustomed to limiting ourselves to what the machine was built to accommodate. The Z on this machine is 12”, but if you have something you need cut that’s thicker than 12”, send it on over! When needed, we tear the slat system out and build special fixtures to drop the workpiece down into the tank. We’ve waterjet cut up to 18” thick stainless steel, so we’re not scared of big stuff!
