The Basics Of CNC Turning

CNC Turning machines, also called live tooling lathes, are ideal for cutting any symmetrical cylindrical or spherical parts. Characteristically, a lathe spins a workpiece on a vertical or horizontal axis, while a fixed shaping instrument moves around it on a more or less linear path. The act of cutting a workpiece on a CNC lathe is called turning.

How CNC Turning Works

CNC Turning uses a subtractive method to create the desired shape. With the G-Code created, a blank bar of stock material is loaded into the chuck of the lathe's spindle. The chuck holds the workpiece in place while the spindle spins. When the spindle is up to speed, a stationary cutting tool is brought into contact with the workpiece to remove material until the desired geometry is achieved.

There are many operations that can be performed on a live tooling lathe, including facing, threading, knurling, drilling, boring, reaming, and taper turning. Different operations require tool changes and can increase cost and set-up time.

When all machining operations are completed, the part is cut from the stock for further post-processing. The CNC lathe is then ready to repeat the operation with little-to-no set-up time in between.

Benefits Of CNC Turning

Like CNC mills, CNC lathes can be easily set up for high repeatability, which makes them great for everything from rapid prototyping to low and high-volume production. Multi-axis CNC turning centers and Swiss-type lathes allow for multiple machining operations in one machine. making them a cost-effective option for complex geometries that would otherwise require multiple machines or tool changes in a traditional CNC mill.

The advantages of CNC lathes compared to ordinary lathes:

1. High processing precision, stable processing quality, precision can reach 0.1mm-0.005mm.

2. Multi-coordinate linkage can be carried out, and parts with complex shapes can be processed.

3. When machining parts change, generally only need to change the CNC program, which can save production preparation time.

4. The machine tool itself has high precision and high rigidity, can choose a favorable processing amount, and has high productivity (generally 3 to 5 times that of ordinary machine tools.

5.The machine tool has a high degree of automation, which can reduce labor intensity.
