If you're interested in open DIY CNC mill designs then pop over to Maker Forums for an update about the Chela Mill's gantry redesign.

There's nothing quite like designing a thing to learn why the existing thing is actually the least terrible option. #ChelaMill #CAD

I started a thread on Maker Forums about an open hardware design for a home shop CNC mill that is designed to cut steel. It's called the Chela Mill. Many details are still TBD so if you're experienced with (or interested in) machine tool design then I'd love to see you weigh in, here or in the forum.

One step closer to using a FOSS CNC controller to make atoms move.

I'm having a heck of a time finding a spindle and VFD combination with enough torque at steel cutting speeds (600 to 1200RPM), has a power drawbar for ATC, and has a taper like a BT30 or TTS. I aim to keep the total Chela mill material costs around $5k so a $4k spindle like CNC Depot's FM series, while excellent for many projects, won't work here:

This Maker Forums post details my first attempt to calculate power requirements for a new machine tool design (the Chela mill) and I would love for folks with more experience to give it a once over as a gut check. #Machining #DIYMill #ChelaMill
