CNC turned parts, also known as Computer Numerical Control turned parts, are essential components used in many industries. These precision-engineered parts play a significant role in the manufacturing process, enabling the creation of intricate shapes and designs with utmost accuracy. CNC turning involves the use of computer-controlled machines to remove material from a workpiece and create the desired shape or form. It is a highly efficient and cost-effective method that offers exceptional precision and repeatability.

The Process of CNC Turning

CNC turning is a subtractive manufacturing process that starts with a solid or cylindrical workpiece. The workpiece is mounted onto a machine known as a CNC lathe, which rotates the part at high speeds while a cutting tool removes excess material. The cutting tool is guided by a computer-controlled program, ensuring precise movement and accurate results.

During the turning process, the cutting tool shaves off layers of material from the workpiece until the desired shape is achieved. This process can involve various operations, such as facing, threading, boring, and grooving, depending on the specific requirements of the part being produced.
