I am trying to produce graphite molds, of pretty small size, so I want a router that's accurate, with automatic tool changer, and to keep cost down, no bigger than necessary... I was thinking 30 cm by 40 cm, or even half that is probably ok...

I am having the same problem I always do when I go to buy diverging, there are endless me too products, each of which probably took significant work for some group of people to design and put in production, and they are all, uh, not very good.

I have used Notre than seven different machines, and the atc really is needed for my application, because a single program could have a neck of a lot of tool changes to get the accuracy, increased tool life, shorter job times, milling fine details, etc.

Any hot tips? Or a small, I.e. 200 watt range spindle with automatic tool change provisions. The tool magazines and programming pic the tool change macros I can do. I will be using a desktop with emc2.

I was going to get something that can do 5 microns accuracy, for the actual Motion of the robot, over a centimeter.

No?

I'm not aware of any small routers with an ATC. Maybe something from China?

I highly recommend you stepcraft cnc with tool changer

they have representative in U.S.A

I seriously suggest that what you need is NOT a 'router' at all. You need a genuine full 3-axis CNC MILL. Why:
For a start the accuracy you are asking (5 um) for is way outside what a router is meant for. A router is typically for wood, with wood tolerances. (wobbly).
To get 5 um you will need a lot more solidity than one would ever get from a router.
It sounds like you are aiming at something a shade more commercial or industrial than bedroom hobbiest: buy quality accordingly.

Mind you, what to recommend to you is a bit more difficult. Do you have a budget?
