What's going on everyone.
So today I'm going to show you how I built my DIY CNC mill.
its been a project I've been working on the last couple of years.
Now I enjoy machining and got a manual lathe, but I've always sort of wanted a mill.
So the one I'll build mine because it'll be cheaper.
So seeking out machines around where I live a few and far between, and they're sort of
quite pricey for what you get.
So this machine just out of scrap metal, all the steel that you see in this machine is
basically grabbed that I've either acquired from friends or pulled out of scrap bins.
So the machine itself was, I mean, it was a fairly rigid machine, but there is a lot
of work I need to do on it.
You don't want to put some bracing in behind the column to stop a bit of the vibration
and things need to do some bracing under the actual frame of the machine itself being that
I'm in a container with a timber floor sort of rocks around the bit more bracing on the
on the actual frame on the legs and then quite thick steel plate to put underneath the feet
to try and spread the load out over the container floor a bit.
pretty much all the hardware like the linear rails, ball screws stepper motors, the servo
drive for the spindle, they're all just off of Aliexpress the spindle itself have made
that all from scratch, just again, scrap metal all turned on a lathe here, old trusty, so
the bearings and the bottom here are 40 milimeter bearings.
And the ones at the top I think are a 32 mil bearing they're not angular contact bearings
or anything like that, like they should be but just to get the machine up and running
it's Good enough.
So I've got a carbide end mill that I use, it's got replaceable inserts in it, so that's
quite handy.
Even the vise I got that from a friend just in a the deal.
So that was quite good.
So yeah, show you a little bit more around the machine.
Some more close up shots, and then should make the machine do a bit of a dance and cut
some steel on it bearing in mind the machine has not finished.
It's far from finished is a lot to do, I still want to rebuild all this holds the spindle,
because at the moment, it's just bits of scrap that I've sort of welded it all together and
it's a bit janky not too keen on how it looks but it does for now.
So hopefully I'll be able to use the actual mill itself to machining the parts.
So this is the top plate in the machine.
It's a 50 mil thick piece of boilerplate that I got off one of my mates, I've cut the sides
of it off, and they now live down here.
So those are now the supports basically for the z column, the linear rails that I'm running
here at 25 mil linear rails that I ended up getting from AliExpress.
And the ball screws are the 16 mil ball screws.
But you're also on Aliexpress stepper motors that were running down here are 3.6 Newton
meters, nema 23 motor that DM542 Driver, they're pretty powerful.
I mean they lifts this head pretty easily and throws that plate around, they're going
to have a bit a bit of power to them.
The spindle motor up here as a one horsepower servo motor.
Again another AliExpress special pretty powerful motor is a lot a lot of talk and you know
when the power really comes on the machine at all ramp the power up so it keeps the RPMs
consistent.
So I guess now you've seen the bit of the machine, you may as well cut some steel with
Well there You go everyone that's, that's my DIY CNC MILL.
