Hello! Cutting Normal Coins?

[berlin]

Hello CNC Europe! I am a newbie to CNC, and while researching solutions to cutting coins (hobby, and one off direct sales) I was referred to CNC routers.

I am working with a small collective of artists who, I believe, could benefit from a technical solution, as the physical production limitations of there craft challenges them to meet demand. A nice problem!

I would like to determine whether a CNC router can be used to cut coins. If you Google images ´cut coins´you can see examples of prior art.

Typically, the profile image is outlined and cut by hand or scroll saw. There are about 40 coins my group work with, so we are interested in creating a stock of the top sellers, perhaps using a CNC router solution. Occasionally we would ad a new design onto an existing coin, or a new coin alltogether.

We have low technical aptitude, basic computer, but high artistic skills.

looking forward to hearing from you!

I doubt that it would be a practical proposition.
The smallest (parallel sided) cutters I work with are 0.5mm diameter and that is huge compared with your blade saws. With CNC you can 'probe' new designs to create the GCode to reproduce the original but it is a lengthy process and the higher the resolution required, the longer it takes. Lasers, suitable for cutting metals are priced well above the hobby market and can be ruled out.
(My CNC machine is here http://www.cooperman.talktalk.net/ and I have shown many examples of what it is good at but I don't think coin cutting will ever be on my list ).

Thanks!

Hello, cnc coins should be possible. Try to ask in the engraving forum.
You don't need a large router, but a small precise machine, high resolution and no backlash. And the artwork need to be digital:-)

there are some discussions about coin and batch milling. Look in the tormach forum, I saw some pictures there
