It's fairly robust. Like a Grizzly G3616. http://www.autoartisans.com/mill/Mill_CNC
But it's got a poor excuse for an ACME feed not on the X axis with about 0.024" backlash. Climb milling in the X direction with slow RPM and a large cutter causes the table to shake. So once the spindle speed control system is in place the whole thing is coming apart for a ball screw retrofit. And belt guards and covers etc. So with the current backlash it may not be robust enough for round cutters.
