Milling Machine Parts. Milling machines have two main parts. The head holds the collets, which hold the tools used to mill the materials. The head moves up and down on the "Z" axis and the tools are spun by a motor. The motor is either a variable-speed motor, or a system of pulleys that is used to vary to the speed of the tool.
