there were hydraulic milling machines sold based on Moog hydraulics and Bridgeport iron. I assume those two companies could screw things up, but the world has moved on. To move a long distance takes a lot of power. Small movements with a lot of force behind them are really easy, that's why you see fatigue machines and other shorter stroke machines with hydraulic servo.
