A manual milling machine is a machine that is operated by hand. It can be used for cutting, shaping and forming metal and other materials. The manual milling machine has a work surface, which is usually horizontal. The workpiece to be machined is clamped to the surface of the table or saddle and the cutting tools are mounted on the headstock.
