Foreceps from Magnified Lab Solutions

foreceps

Magnified Lab Solutions provides advanced tools for histology: working with living tissues under a microscope. As you might imagine, working with things on a tiny scale requires precision equipment. Magnified Lab Solutions' process for manufacturing high quality, feature packed foreceps begins with Big Blue Saw. We use their CAD design to waterjet cut the stainless steel blanks which ultimately become finished instruments.

They do a lot of specialized work to finish their foreceps from the waterjet cut blanks we provide. Matt Sabater gives the rundown on all the skilled work they do to turn the blanks we create into finished products:

Starting from the water-jetted forceps blanks we variably work harden them. We like the tips and spring zone to have a different level of hardness then the forceps body. From their we move to initial finishing operations (removing burrs, marks, etc.). We use a custom manual press brake to perform the bending operations. Next the forceps move onto secondary finishing (graining, polishing). The most difficult part is maintaining dimensional symmetry throughout the processes (really just a careful eye and a steady experienced hand). Final steps are etching logos, shaping the tips, passivating, and inspection. Most forceps are just stamped and forged from two separate blanks. To do it from a single blank and add bending and work hardening to the mix is when craftsmanship really comes into play.

Aluminum Alloy 7075 Now a Standard Stock Material

 

You've been asking for it, and now it's here. You can now order custom waterjet cut aluminum 7075 parts directly from our website.

I used this material in my robot Flipper for Robot Battles this year. You can see it in the photo above: the claws on the robot are aluminum 7075 in 3/8 inch thickness. It held up spectacularly when lifting opponents, falling off the stage, and being attacked by other robots. Flipper went on to win the final rumble in the 12 pound division.

Aluminum 7075 offers greater tensile strength than 6061 or 5052 alloys, so it's fantastic for any application where the parts will be undergoing mechanical stress. On the flip side, it's not weldable like 5052 or 6061, doesn't have the formability of 5052, and is more prone to corrosion in harsh chemical environments. But if you're looking for an aluminum with an ultimate tensile strength that's 85% higher than alloy 6061, 7075 is the way to go.

Order your parts in aluminum 7075 from our website today!

 

 

Wikispeed Open Source Road Legal Car

Wikispeed is an open source road legal car, for commuting and racing. They take the idea of open source seriously and everyone is invited to collaborate.

Above you can see Car #007, built for testing new part versions. Many parts on this car were waterjet cut by Big Blue Saw: the front pedal plate, the suspension corners, pieces in the engine module and interior, and more.

Being open source, Wikispeed collaborators make use of a variety of CAD software, based on the preference of the individual designer. The most used package is Geomagic, with some members preferring SolidWorks, FreeCAD, or AutoDesk Fusion. The design files are available for free download

This video shows the Wikispeed SGT01 100 MPG car.

Joe Justice of Wikispeed sent us a few photos of the Wikispeed parts made by Big Blue Saw.
