Overview: What is CNC Turning?

A CNC lathe, also known as a live tooling lathe, is the ideal machine for producing symmetrical cylindrical or spherical components. Its fundamental operation involves rotating the workpiece around a vertical or horizontal axis, while a stationary cutting tool moves linearly along the workpiece to shape it. This material removal process, where the workpiece rotates against the cutting tool, is referred to as turning.

How CNC Turning Works?

CNC lathes utilize a subtractive manufacturing process to create desired shapes. The workflow begins with loading a blank cylindrical bar of stock material into the lathe's spindle chuck, which securely holds the workpiece in place as the spindle rotates it. Once the spindle reaches the programmed speed, a stationary cutting tool is brought into contact with the rotating workpiece to progressively remove excess material until the final geometry is achieved, following the toolpaths dictated by the G-code program.

Live tooling lathes are capable of performing various machining operations, including facing, threading, knurling, drilling, boring, reaming, and taper turning. Different operations may require tool changes, which can increase costs and setup times.

After all machining operations are completed, the finished part is cut from the stock material for any further post-processing steps. The CNC lathe is then ready to repeat the production cycle with minimal setup time required between parts.

This subtractive process enables CNC lathes to efficiently produce symmetrical cylindrical or spherical components with high precision and repeatability.

Types of CNC Turning

These lathes can perform various operations, including facing, threading, knurling, drilling, boring, reaming, and taper turning. After all machining steps are completed, the finished part is cut from the stock for any further post-processing. The CNC lathe is then ready for the next production cycle with minimal setup time required.

Other Benefits Of CNC Turning

Like CNC mills, CNC lathes can be easily configured for high repeatability, making them suitable for applications ranging from rapid prototyping to low and high-volume production runs. Advanced multi-axis CNC turning centers and Swiss-type lathes allow for multiple machining operations to be performed in a single machine. This capability makes them a cost-effective option for producing complex geometries that would otherwise require multiple machines or frequent tool changes on a traditional CNC mill.
