CNC Turning Services
IATF 16949:2016 certified precision CNC turned parts in metals and plastics. Prototype to production, one turnkey partner.
What Is CNC Turning?
CNC turning is a subtractive manufacturing process where a workpiece is clamped in a rotating chuck and shaped by a computer-controlled cutting tool that removes material as the part spins. A CAD model is converted into G-code, and the lathe executes cuts with repeatable accuracy to ±0.01 mm. The process is the standard method for producing cylindrical and conical parts — shafts, pins, bushings, fittings, and connectors.
Modern CNC turning centers with live tooling can also perform milling, drilling, and tapping in the same setup, eliminating secondary operations and improving positional accuracy. This is fundamentally different from CNC milling, where a rotating cutter shapes a stationary part. Meco provides turning as part of our turnkey manufacturing model — integrated with surface finishing, mechanical assembly, and global logistics, all under IATF 16949:2016 certification.

CNC Turning FAQ
What is CNC turning?
CNC turning is a subtractive process where a rotating workpiece is shaped by a computer-controlled cutting tool on a lathe. It produces cylindrical, conical, and contoured parts — shafts, pins, bushings, fittings — with accuracy to ±0.01 mm.
What is the difference between CNC turning and CNC milling?
In turning, the workpiece rotates (ideal for round parts). In milling, the cutter rotates (ideal for flat surfaces and 3D shapes). Many parts benefit from both, which is why Meco integrates both under one roof.
What materials can be CNC turned?
Metals: Aluminum (6061, 7075), Stainless Steel (303, 304, 316, 17-4PH), Carbon Steel, Brass, Bronze, Copper, Titanium. Plastics: Nylon, Delrin, PTFE, PMMA.
What tolerances can CNC turning achieve?
±0.01 mm per ISO 2768/286. Surface finishes Ra 0.4–3.2 μm. CMM verified to ±0.002 mm. See our CNC machining cost guide for tolerance-cost tradeoffs.
What is live tooling in CNC turning?
Live tooling means powered cutting tools on the lathe that perform milling, drilling, and tapping while the part stays in the chuck. This eliminates secondary setups for radial holes, flats, slots, and grooves.
What industries use CNC turned parts?
Automotive (shafts, fittings), aerospace (bushings, actuators), medical (surgical instruments), heavy equipment (hydraulic rods), industrial (valve stems), and electronics (connector pins).
