CNC Turning FAQ
What is CNC turning?
CNC turning is a machining process where the workpiece rotates in a chuck while a stationary cutting tool moves to shape it. It produces cylindrical parts — shafts, bushings, flanges, pins, and round components. Modern CNC lathes are computer-controlled and can achieve tight tolerances of ±0.01mm on diameter dimensions. Turning centres with live tooling (milling capability) can produce complex parts with both turned and milled features in a single setup.
What is the difference between CNC turning and CNC milling?
In CNC turning, the workpiece rotates and the tool moves — producing cylindrical/round parts like shafts, bushings, and flanges. In CNC milling, the tool rotates and the workpiece moves — producing prismatic parts like brackets, housings, and blocks. Mill-turn centres combine both: the machine can turn and mill in the same setup, handling complex parts with cylindrical and flat features without transferring between machines.
What tolerances does CNC turning achieve?
CNC turning achieves ±0.01mm on diameter dimensions as standard. ±0.005mm is achievable on critical features. Surface finish of Ra 0.8 μm is standard for turned surfaces; Ra 0.4 μm is achievable with fine finishing passes. Roundness (cylindricity) of 0.005mm is typical. Diameter consistency over length depends on part length-to-diameter ratio — long slender shafts may require steady rest support for tight tolerance.
What materials can be CNC turned?
All common engineering materials can be CNC turned: aluminium alloys (6061, 7075, 2011), stainless steel (304, 316, 303 free-machining), carbon and alloy steels (1018, 4140, 4340), titanium (Grade 2, Ti-6Al-4V), copper alloys (brass C360, phosphor bronze), engineering plastics (Delrin, PEEK, nylon), and exotic alloys (Inconel, Hastelloy). Free-machining grades (303 stainless, C360 brass, 2011 aluminium) are preferred for high volume turning.
What is a mill-turn centre?
A mill-turn centre (also called a turning centre with live tooling, or a CNC lathe/mill) combines CNC turning and milling capability in one machine. The machine can turn cylindrical features, then stop the chuck and use rotating live tools to mill flats, drill off-centre holes, cut keyways, and machine complex features — all in one setup. Mill-turn centres are ideal for parts that are primarily cylindrical but have additional milled features, eliminating the need to transfer between a lathe and a milling machine.
