Really, really small CNC mills

[Gene Hacker]

As you all may know CNC milling machines can be quite useful, but also
quite big... However it is possible to make really small CNC "mini
mills."

BEHOLD! A palmtop CNC milling machine from Japan(seems to have a
software or design problem though):

Here's a Korean mini-mill for $1200.45, wonder why we don't get such
nice things here in the US? It's only accurate to ±0.3 mm though(about
as accurate as a RepRap). It's also very dangerous...

The absolute smallest milling machines can get, a pocket mill, a
milling machine(WITH 6 AXES!) that could conceivably fit in your
pocket. Just imagine, personal fabrication in your pocket! Utilizes
electrochemical machining and piezoelectric actuators. Sadly, it
appears it was never built:
