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 -

Machine URL Price (UKP) X Y Z weight Notes
Tormach PCNC 1100 link ~£5585 450 237 406 514kg Very high-end hobby / low-end pro machine
Tormach PCNC 770 link ~£4512 350 188 325 301kg Very high-end hobby / low-end pro machine
Seig KX1 link £3135 260 115 185 86kg comes with £460 of useful accessories
Seig KX3 link £4725 295 150 275 201kg
Proxxon 500 link £4510 310 100 220 47kg Very lightweight for its size, unlikely to be suitable for much metal milling

Weight gives a good indication of quality/stiffness for a given size machine

All machines are likely to need a selection of accessories such as software, collets, vices, clamps, chucks, coolant, cutters and a stand, expected to cost around £1000.
