Need Help!- Want to mill iron or steel What do i need ?

[cnc2]

Hi every body on the forum,

I'm about to build a 3 or 4 axis milling machine & i want it to mill steel or iron, so i'm in the "gathering info" phase because i can't figure out what it really takes to mill iron or steel, my questions are:

1) what cutting power do i need on the tool ?

2) what servo motor torque do i need for that cutting power ?
(some math please)

3)==> if you can point me on the cheapest model & a supplier for such servos, is the UHU servo controller enough to drive them ?

4) what is the best drive to suite that purpous, belt drive or threaded rod ? (some math please) (some pics of a diy metal milling machine if available)

5) No, i won't ask you to build it for me ! lol


Thanks for your readin' !

download the "machine zip"
this will give a general idea of horse power and torque on the cuts you plan to do

man, it's a good soft, but how should the machine be constructed (designed) to resist to deformation when milling steel or iron ?

Any pic of a home built machine that's capable of milling iron or steel ?

what material is it built from ?

I have 12 mm diam rails for Y axis and 15 mm for X, these rails were salvaged from old copier machines and are 50 cm and 60 cm long respectively, will they do the job or not ?

Thanks !
Best regards,
