What is CNC Turning?

CNC turning is a manufacturing process that relies on a computer program to remove portions of material from a workpiece and create desired parts. The process starts with you creating a 3D CAD model of your desired part before converting it into G-code (computer program) using computer-aided manufacturing (CAM) software. The G-code then automates the operation of the cutting tool and workpiece to create your desired shape.

CNC turning is quite similar to the CNC milling process. However, unlike CNC millingㅡwhich keeps the workpiece fixed as the cutting tool rotates against itㅡthe cutting tool in a CNC turning machine is held in place as the workpiece rotates against it.

Look at it this way. CNC turning is a process that manufactures parts by “turning a material” against a fixed cutting tool to form the desired shape

Why CNC Turning?

CNC turning is ideal for creating cylindrical shapes or parts that are symmetrical near their axis, for example, a chess pawn, bolts, rivets, ball bearings, and washers. CNC turning also solves some of the manufacturing challenges associated with CNC milling. For example, it allows you to create undercuts or relief grooves easily, whereas CNC milling machines require specialty cutting tools to achieve this.

CNC turning machines also allow cutting operations to occur along 3-, 4-, or 5-axis, allowing you to perform taper turning, knurling, threading, and parting, among other operations. This subtractive manufacturing process is particularly suited for rapid prototyping and low volume production.

Nevertheless, CNC turning can be used in tandem with CNC milling to create high-quality parts accurately while meeting tight tolerances.
