Hello,

I've been trawling though the threads here, but it seems that my requirements might not fit the typical cnczone metal machine purpouses, so I'd appreciate some guidance.

Basically I would like to build a machine capable of cutting molds in aluminium billet for an injection molding machine.

Now I notice that most users are interested in cutting larger, thin material. My requirements are:
1) Smallish footprint, say 150mmx150mm
2) Deep Z cutting (up to 50mm)
3) 3 axis (no undercuts to worry about)
4) Fine surface finish for smooth molds ( I guess I'll need to switch to smaller bits after cutting the coarse form)
5) Don't care if the cutting time is very slow
6) Ideally desktop size(ish) mill. No need for a shop filling monster.

I feel like my requirement for small area, yet deep metal cutting leaves me stuck between weak desktop "engravers" and enormous door cutting machines.

I'd appreciate it if someone can point me towards some similar builds, kits or discussions. I have access to a shop for help and have built a decent 3D printer, but am by no means an expert machinist. Looking forward to learning.

Thanks!
