Sometimes when I need to rout something I can't help thinking that it would be so much easier if I could guide the wood past the bit with a x-y-table.

Would it be possible to use a metal milling machine for this task?

The ones I've looked at has a maximum speed of 3000 rpm or only slightly higher and I would think this is way less than is required to obtain a clean cut.

Any opinions and/or advices are very welcome :-)
