The Advantages of the CNC Turning Process: Lathes vs. Milling Machines

While CNC milling is the primary machining operation for flat surfaces and complex component geometries, CNC turning is the ideal process for producing cylindrical or conical shapes in workpieces while maintaining precision tolerances. Round profiles can be machined much more quickly, efficiently and reliably using a lathe compared to a CNC milling machine.

In many advanced aerospace, defense and industrial machining applications, lathes and milling equipment are used in conjunction to provide more versatile CNC mill-turn solutions. With mill-turn operations, a cylindrical or conical workpiece can be produced through turning before it is milled out with more complex geometrical features.
