Polymer Man, what kind of cuts can your machine do? Maybe that wll
guide the OP in the right direction.

Thank You,
Randy




The one will take a very heavy cut at high speed. I have a large part
here I machine in plastic where I'm removing over five pounds of chips
in about four minutes, at 1,600 IPM feed rates. The rapids are 4,000
IPM. The screws are probably 1 in 1. You don't need motors that large.

The little retrofit mill with little 600 oz in motors are geared 5:1
on 5 in 1 screws. It's maximum feed is only 40 IPM. Still a useful
machine for certain types of things. But you probably wouldn't want
motors smaller than that.

Both machines are designed to cut aluminum so long at you didn't plow
deeper than 1/4" per pass with a 1/2" cutter.
