What is Automatic Bar Machining?

Automatic Bar Machining Automatic Bar Machining usually refers to a metal working lathe. These machines, also known as screw machines, are originally designed for machining a variety of metals and evolving to machining plastics and other materials. These adaptable machines can be used in a broad variety of applications. 
Automatic lathes, also sometimes called screw machines, although the parts they produce are rarely screws, are used for small- to medium-sized parts along with high-volume runs, usually 1,000 parts and up. All screw machines are automatic, meaning, once they are set up the can run continuously producing turned parts with minimal interactions.
Automatic Bar Machining describes the automatic screw machine cycling with the continuous feeding of the raw material (bars) for rapid, consistent, high volume production of turned components.
