Hex Bolt Auto Feeding And Screwing Machine

Screw machines are machine tools that use a number of cutting tools, fed into a rotating rod or bar, to make screws and other turned parts. A screw machine is a type of automatic turret lathe, that performs turning, lathing and cutting tasks to produce high-volume, low-cost parts.Also known as an automatic lathe or turning center, today's screw machines are Computer Numerically Controlled (CNC) machines. A screw machine comprises a hollow spindle and cams. A bar is fed into the machine, and the unwanted material is chipped away to create different types of screws, studs, and bolts.The two primary functions of a screw are to hold things together or to lift objects. The threading around the shaft in a screw makes it an efficient tool to hold things together. The threads grip the surrounding material like teeth, resulting in a secure hold.
