CNC (Computer Numerical Control) Machining Plastic is a manufacturing process where computer-controlled machines are used to cut and shape plastic materials into specific geometries precisely. It involves programming a computer to guide a machine tool, typically a milling or turning machine, to remove material from a plastic workpiece until the desired shape is achieved.

  • Understanding the CNC Milling and Turning Process

CNC Milling and Turning are two of the most popular types of CNC Machining for plastic. In CNC milling, a spinning cutting tool moves across the surface of a plastic workpiece in a pre-programmed pattern to gradually cut away material and create the desired shape. CNC turning involves rotating a plastic workpiece while a cutting tool shapes it into a cylinder or other symmetrical shape.
