The ProtoTRAK EMX is great for first-time CNC users or for basic knee mill work.

Get it integrated into a King Rich Turret Mill

Essential features – minimal complexity.

The ProtoTRAK EMX has the features you really need to work productively using a knee mill, but leaves out features that make other CNCs more complicated.
