Briefcase mill

briefcase-mill

Take the machine shop with you; that’s the mantra which drove [Ryan] to build this CNC mill in a briefcase. That album will give you a taste of the final product. But you’ll want to dig through two pages of his forum thread starting with this post in order to behold the build process.

The image above is only part way through the fabrication, but we thought it gave the best overall view of his work. It’s missing the cables which connect to the control circuitry in the lid. The bed has also not been installed and this was before he fabricated the protective case for the PCBs.

Getting everything to fit inside of a folding case was quite a trick. Of course he used CAD to make sure it was possible. There are several places where the clearance when closed is about 2mm. We’re shocked by the build quality of the mill itself. It’s a novel idea to make it portable, but the accuracy and reliability of the machine didn’t suffer for the concept.

If you need a desktop mill that’s not quite as portable here’s a project which will dish out some inspiration.

    Damn, that is awesome! He could totally sell those!

    I’d love to see a video.

    Not to be a stickler here but it’s usually called a CNC router, not a mill. The maker himself calls it a “router”, so why change? “Mill” kinda assumes WAY more rigidity in the body and ability to cut the entire depth of (thick flat pieces of) material. This device can do shallow grooves and engrave nicely, following intricate routes, hence the router.
    Cheers!

    That’d be fun to take through security ;-)
    Awesome build though!

    Two changes. add a whole sheet of plexi across the control side to keep shavings out, maybe hinge it so it can flip up as a shield.

  6. I wish he makes it open source

    He had this on display at the Calgary Maker Faire, it’s remarkable.
