CNC turning is a manufacturing process in which a computer numerical control (CNC) machine is used to produce cylindrical parts. The process involves using a lathe or turning machine, which is a machine tool that rotates a work piece on its axis while a cutting tool is used to remove material to create the desired shape.

In CNC turning, the cutting tool is mounted on a tool holder that is attached to a turret or tool post. The turret or tool post is mounted on a slide, which moves the tool in and out of the work piece as it rotates. The movement of the tool is controlled by a computer program, which allows for precise and consistent cuts to be made.

CNC turning is a highly efficient and accurate method of producing cylindrical parts. It allows for the production of complex shapes and geometries with a high degree of precision, and is widely used in a variety of industries, including aerospace, automotive, and medical device manufacturing.

There are several types of operations that can be performed on a CNC lathe, including:

Turning: This is the process of rotating the work piece and using a cutting tool to remove material from the surface to create a cylindrical shape.

Facing: This is the process of using a cutting tool to remove material from the end of the work piece to create a flat surface.

Chamfering: This is the process of using a cutting tool to create an angled edge on the work piece.

Threading: This is the process of using a cutting tool to create threads on the surface of the work piece.

Parting: This is the process of using a cutting tool to separate the work piece into two pieces by cutting all the way through it.

Drilling: This is the process of using a cutting tool to create a hole in the work piece.
