I’m in the middle of cutting this mold on my cnc router. I use the Shapeoko from Carbide which is about 1500 last I looked. The 200 machines may not be rigid enough for aluminum but then again they may work great. I haven’t had to worry much about cooling or chip clearing. I have a compressor with a nozzle near by if I do need to clear something quick. They a fun to play with, I’ve been cutting jig head molds as well.
