Thread Turning Knowledge

What is Thread Turning?

Thread turning is a method used to create screw-like grooves, known as threads, on a cylindrical object or inside a hole. This process is usually done on a machine called a lathe.

During thread turning, the workpiece (the rod or tube) spins, while a special cutting tool moves along it. This tool cuts the threads into the surface of the workpiece, similar to the threads you see on a bolt or the inside of a nut.
