Moving gantry CNC machining center

[giladv]

Hello folks!

My name is Gilad, i'm from Israel and this is my first thread here.
I wrote code since i was 13 and i'm still doing it for a living (turning 30 soon).
since the first generation of diy cnc machines started to pop i knew i wanted to take on a project like that myself.
so i consumed every piece of information available online until i decided to go for it.

also, i wanted to emphasis that this is my first time doing parametric modeling, designing a machine or building something physical myself (unless lego technic counts).
i have no prior cnc or machining experience so everything i say or do is based only on theoretical knowledge i picked up and pure instincts.

Requirements:
- rigid enough to mill aluminum reliably (and steel occasionally).
- quiet, light and small enough to be able to run in my apartment
- all in one, enclosed solution
- flood/mist cooling & chip pan
- the machine should be beautiful and look professionally made

Totally unnecessary things i decided to do anyway:
- ATC
- Rigid tapping
- BT30 standard tooling
- Fast rapids

My design


Some specs:
- 20mm Hiwin linear rails on all axis
- 20mm/10mm pirch C7 grade ballscrews with and bearings on all axis
- machined parts (incl the base) will be Al 7075 T6
- milling head: 8000rpm BT30 90mm spindle, 1.8kw AC servo
- Y axis Al profiles are Item's 120X120mm heavy variant
- X axis Al profile is item's 160X80mm heavy variant
- gantry and side profiles will be filled with epoxy granite
- motion servo's will probably be X4 nema34 clearpath servo (CPM-SDSK-3421P-ELN)

Progress
- most of the parts have arrived or on their way. i'm still having trouble justifying to myself the clearpath servo's but i'll get them soon.
- machine base is done


thanks,
Gilad

Really cool design! Have you considered adding way covers? It might be a nice touch, especially if you are running coolant.

thanks!
i actually designed my axis with way covers in mind, just couldn't really model/assemble the covers as i wanted on Fusion360.
the only pain point is that the covers take considerable amount of space along the axis..

just an update, got new toys from Teknic

- X4 clearpath CPM-SDSK-3421P-ELN servo's
- IPC-5 800w 75v power supply from Teknic
- power and signal cables





more updates soon!

Cheers.
