The vertical milling machine is a precision tool used for shaping and fabrication by the removal of stock typically from metallic work pieces. Plastics and other materials can also be machined on the mill depending upon tooling and material. Mill controls may be manually operated, computer numerical controlled (CNC), or a combination of both.

The roller tries to ride over the bed, but swims through it. Causes a low frequency vertical movement. Snowplowing pushes at the roller, causing a twist in the mill body. When it snaps back, causes a higher frequency torsional vibration. Causes: Too much feed High internal recirculation Not enough grinding Speed of deaeration.
