Hiya
I wanted to get a CNC mill/router and thought here would be a good place to start.
My wife makes brooches out of 1mm thick copper sheets.
At the moment she cuts the shape out with a hand fret saw, this takes ages and costs an absolute fortune in blades.
So I'm thinking that there must be a better solution to this, I'm thinking that a CNC machine would allow me to knock a sheet of these out easilly and earn me much needed brownie points.
Any suggestions gratefully received.
I have looked at something like this, any good ?Last edited by Chris J; 24-04-2012 at 05:34 PM.

Copper is an absolute bitch to machine, dead gummy and just wants to weld itself to the tool. Have you given any thought to a plasma cutter?
All depends on the amount of detail needed.John S -

Hi Chris,
You don't mention if the designs are simple or complex, but have you tried the band saw / jigsaw or sander type route? If they are all the same design, a Flypress? It might work out cheaper? (more brownie points too! :-)

The issue with a bandsaw and difficult to cut materials is new blades will cost about £6-£8 and may not last longer than much cheaper blades for fret saws.
I didn't have problems when cutting 5mm thick copper on my CNC router, but maybe I just got lucky.
Roughly many of these broaches is your wife making? If they're all different shapes then a fly-press wont be cost effective, but getting them laser/plasma cut might be? If you do cut them on a router you're in danger of making her redundant as the router can of course do all the engraving...

See here:

The outer profile and 2mm wide slot were on my CNC router and the 0.5mm slots were cut with a slitting saw on the milling machine. To be honest I can't remember which cutters I used. Probably these:

The same seller has plenty of smaller ones too...
