What is a Screw Machine, and How Does it Work?

How Screw Machines Work. Screw machines are automated machines that are used to produce large quantities of small to medium-sized parts. They work by feeding a bar of material into the machine, which is then clamped in place and rotated at high speeds. As the bar rotates, cutting tools are used to shape and form the material into the desired shape.
