ROT: Computer milling machines

I'm after a milling machine - not high power, more focus accuracy for
making shells from coins. The type of thing I'm after will machine
out a 2p so I can fit a 10p in it. (This is an example of the
accuracy I need, not the actual application...) Erm, if that makes
sense...

Also important that it'll take a basic CAD applications output and be
able to mill in a name in 0.1mm (1/10mm) script.

I know this is prolly pushing the ROT, but there bein' some injineers
erabouts anall...

You only need model engineering scale stuff. Look in a copy of Model
Engineering. Or look for "Compucut"

A baby milling machine can be outfitted with CompuCut for around 1000
quid all in.

There is a Yahoo group CAD_CAM_EDM_DRO which is an absolutely priceless
resource.

If you want something knocking up let me know next week. Axminster do a
nice tiny machine that would make a neat base unit.

1/10 mm is only 2.5 thou high. That would need very high resolution
steppers and really good screws.

Ah, hadn't thought about scaling it down to model making equipment,
good suggestion...

Which is _exactly_ on my budget!

If I can ever get YohooGripes to accept that (even though I'm on many
lists as a result of the old, pre-yahoogroups) and let me login, I may
subscribe...

May need a little chat, then

Yeah, I'd eventually want to get even better accuracy too, but should
that come to be, I'll happily pay for it...

This has all been somewhat unfortunately forced upon me at short
notice due to an alarmingly early mention of www.snotmagic.com five
months before we were intending to launch the site :-(

(There's not much on the site at present, another 'quick to do' on the
cards - if you'll excuse the pun...)

would an' all. serious precision stuff. You might be into watchmaker's
territory, I reckon.

I'd be thinking that slide ways and gibs would be too sloppy, and
looking at precision ballslide ways.

No it's not it is nearer 4"'

If at first you don't succeed,
maybe skydiving's not for you!

You're right, its roughly 40 thou per mm.
so 1/10mm = 4 thou.
Sorry.
