I'm selling my Milltronics Partner 4 CNC knee mill. It has been upgrade to Centroid All In One control and servo motors. Includes Minimum Quantity Lubrication unit for cutting fluid, Automatic lube pump for ways and ball screws, Push button CAT40 or BT40 tool changes using pneumatic cylinder. 32" in X, 16" in Y, and 5" in Z (plus the ability to run the knee up and down). Spindle range of up to 5000 and down to 500 (I think) in hi-range, 50-500 in backgear. I built a shower curtain rod to enclose the mill area to keep chips from flying everywhere. Tachometer to verify spindle speed. Tool length probe for setting tools and lots of tool holders of various styles. Wireless Centroid MPG for setting up and control at the machine. Runs on 220V single phase, so no need for a phase converter.
