Waterjet Wednesdays!

I realize it's been a little bit since that last post so I'm back for more. I actually just updated our Flickr photostream too, so you may have to check that out. There's some really neat pictures on there now: Fedtech Flickr

Also, if you didn't know, we're located in Minnesota where the sun shines when it wants to and the same goes for the snow. It's finally raising past 20° F and we're loving the sunshine, we kind of forgot what it looked like! You can see the snow is melting, the ice is retreating, and our fellow Minnesotans are becoming much friendlier... thank goodness for springtime!

Well, without further ado, we must continue on to Sarah's super sweet pick of the week! Where I choose the coolest project that has gone through Fedtech's production floor and give you, the readers, a little insight behind the project. It's a fan-favorite, so read on!

Sarah's Super Sweet Pick of the Week

I'll admit it, I'm a sucker for shiny things but these parts are beyond that. These custom waterjet cut parts were processed from .002" thick brass (6" x 60" sheets). To be used as wear block shims, they will be the perfect solution for the customer's application in the food industry.

The thickness of these parts was almost half the thickness of a regular sheet of paper (which comes in at .0038" thick). If that gives you an idea of thin these parts were, you can certainly understand that a certain level of intricacy was needed as well when waterjet cutting these parts.

Questions of the Week

Q: Can a waterjet cut plastic?
A: Yes, it can. You'd preferrably want to use water-only waterjet cutting but abrasive waterjet cutting would work as well depending on the application you'd be using the plastic for.

Q: Can you cut armor plate with waterjet?
A: You definitely can, and we do! Quite a bit actually. We're able to waterjet cut armor plate and ballistics up to 12" thick and from all different types of plate. Click here to see a specified page on the topic.

Q: Can you define; high speed machining?
A: Oh yes, we have defined that in our glossary section of our website. Jump to the H's here...

Q: What's the difference between cutting stainless steel with a laser or a waterjet?
A: That's a great question. The most basic differences can be seen in 1) heat affected zones, which laser cutting has and waterjet does not have. 2) laser cutting typically cuts up to 5/8" thick stainless steel. Anything thicker than that and you may need to use waterjet cutting. 3) Laser cutting typically has tighter cutting tolerances, so if your part includes intricate designs and is less than 5/8" thick, then laser cutting is the ideal choice.

Q: How can I cut thick aluminum sheets?
A: Thick aluminum plates can be cut easily with abrasive waterjet cutting. See a thick aluminum project that we cut here with waterjet to get a good idea of how it works.

Q: How can I make a custom gasket?
A: You can order it. From us. First request a quote and we'll get you pricing. Then we can waterjet or laser cut it to your dimensions and tolerances. Choose your material according to your application (ie. heat resistancy, soft/hard material...) Visit our gaskets page here...


Well those are all the questions that I have time for today! Tune back in soon to catch more questions answered, and another pick of the week!

Have a great wednesday!
