Re: [CAD_CAM_EDM_DRO] Re: Proxxon Mill CNC Conversion

Thats a cool website you have. I like that little mill. It would be fun to put on the desk and experiment with. I might do one of those someday. Like running a Bridgeport all day isn't enough.

My old boss was into electric flight and I dabbled in it a bit as well. He was amazed as was I of the tiny carbon fiber helicopters not much larger than a coffee cup that was R/C controlled. Did you build that one too?

Covers my conversion, a digitizing probe I made for it and on it and
a 4th and 5th axis add on I made. Also shows some other things made
using it such as propeller moulds.

The working area is more like 1.5" by 5" It is a very small mill,
good if you want to make very small things. If you don't then a
bigger mill will suit you better.

General comments: Spindle is good, runs to over 20k and is quite
quiet. Takes tooling upto 1/8" maximum. Construction is pretty
good, it has gibs and the nuts have VERY little backlash. I
recently replaced the washers that act as thrust bearings with
normal 6mm ID bearings and that has reduced backlash to nearly
nothing. Before if you tightend out the axial play of the screw it
would produce too much friction.
