The Precision CNC Turning Process

Precision turning, especially when done with Computer Numerical Control (CNC) machinery, is a craft that marries traditional machining techniques with modern technology. But how does this process work

Lathe Operation

At the heart of turning lies the lathe, a machine that holds and spins a workpiece around an axis. Traditional lathes required manual operation, where the machinist would physically control the cutting tool’s movement. In the context of precision turned parts, the lathe’s accuracy plays a pivotal role. The machine holds the raw material, be it brass precision parts, steel turned parts, or any other metal, and rotates it. A cutting tool then moves linearly, carving out the desired shape and design.

Computer Numerical Control (CNC) Precision Turning

While the traditional lathe operation relies heavily on the machinist’s skill, CNC takes it a step further. Here, the movements of the cutting tool are controlled by a computer, interpreting a CAD (Computer-Aided Design) file. The precision achieved with CNC turned components is unparalleled. The computerized system ensures every cut, every groove, and every contour matches the exact specifications provided in the CAD file.

Materials Commonly Used

The choice of material for turning is vast, each offering its unique properties:

  • Brass Turned Parts: Preferred for its malleability and excellent thermal conductivity. Commonly used in electrical components and decorative pieces.
