Another concept for a mill. This bedmill has a high ability to replicate itself while kneemills don't have this. A kneemill hasn't enough longitudinal travel to machine the table or the longitudinal bedways of another knee mill. Also its rigidity to machine parts of another knee mill is doubtful. | |||
A bedmill can easily manufacture its own bed in two parts, these two parts have to be assembled while setting up the mill. A bedway in several sections is standard with large milling machines. | |||
Bedmills provide a stable base for CNC and don't have such an difficult design as the knee. | |||

Another concept for a mill. This bedmill has a high ability to replicate itself while kneemills don't have this. A kneemill hasn't enough longitudinal travel to machine the table or the longitudinal bedways of another knee mill. Also its rigidity to machine parts of another knee mill is doubtful. A bedmill can easily manufacture its own bed in two parts, these two parts have to be assembled while setting up the mill. A bedway in several sections is standard with large milling machines.
Bedmills provide a stable base for CNC and don't have such an difficult design as the knee.

This is a concrete mill, where the head is attached to a top piece. Head can be rotated for horizontal or vertical milling.
Eric MacNeil Version
