The Hurco Horizontal Boring Mill has a small footprint, especially considering the large work envelope, and is heavier than competitive boring mills in its class. It has a geared head spindle with two speeds and hardened box ways, a 4.33-inch diameter quill that allows you to use shorter tools, a contouring 4th axis rotary table (not just positional) and linear glass scales to maintain thermal stability and increase accuracy among many other things.
