CNC turning is a machining process that involves the rotation of a workpiece while a cutting tool removes material to create the desired shape. The cutting tool is controlled by a computer program that specifies the tool’s movements, depth of cuts, and other parameters
In the realm of modern manufacturing, CNC turning has emerged as a dominant technique for creating intricate parts with exceptional accuracy. This method utilizes computer-controlled machines to remove material from a workpiece and shape it into the desired form. Unlike conventional turning, which requires manual operation, CNC turning offers enhanced precision, speed, and repeatability. This automation allows for precise and consistent results, eliminating human error and increasing productivity.
