Equipment/CNC Metal Mill
A CNC Milling Milling Machine is a computer controlled tool that uses a rotating cutting tool to cut into a stationary workpiece.
Here's a nice video showing the basic movement of both CNC and manual vertical mills - N.B. the guy in the video shouldn't be wearing gloves, as they can cause very nasty accidents if your hand comes into contact with the cutter!
Just a quick table on a few small CNC mills I found available readily in the UK -

Caveats: These were mostly based on searching out of interest in PCB production. Prices are almost certainly not correct, extras may be needed and VAT is probably not includede - use as a guide only.
