But before you make your choice, consider these three primary considerations: Size. Size matters. If you need a machine that can handle industrial-sized workpieces, you need an industrial-sized mill. You might want a reinforced milling head on a vertical mill, or you might decide to jump straight to a horizontal mill.

Milling machines can weigh anywhere from 15 to 5,000+ pounds. A micro mill has capacities that are a fraction of those of a vertical mill, but regardless of physical size, accuracy is built on a rock-solid foundation. Usually this is provided by a general structure of cast iron.

Design for CNC Machining Parts. CNC machines are a marvelous technology that offer a range of possibilities for accurate parts, but your end-product is only as good as the design you set out with. There are some major considerations one has to make when developing any machined part, taking into account its full geometry.
