Ive got a 3-z that is a very nice fast plastics and aluminum mill.
Pretty darned rigid when the head is locked own, and will turn a
cutter Really fast. Pretty accurate as well. A buddy came over
earlier today and he used it to cut some copper gaskets for some sand
rail project he is puttering with. Put a 1/8" 4 flute TiN endmill in
there, ran it up about 8000 rpm and just cut thru it like a hot knife
I wish I had a manual for mine so I could figure out how to do 1:1 or
a bigger work piece from a small pattern when in pantograph mode
