Introduction to CNC Metal Turning

In the realm of precision manufacturing, CNC metal turning stands as one of the most critical processes for creating high-accuracy cylindrical and conical metal parts. At China Metal Castings, we leverage state-of-the-art CNC turning technology to produce components that meet the exacting standards of industries ranging from aerospace to medical devices. Our advanced machining capabilities allow us to work with an extensive range of metals, achieving tolerances as tight as ±0.005mm and surface finishes as smooth as 0.2μm Ra.

What is CNC Metal Turning?

CNC metal turning is a subtractive manufacturing process where a computer-controlled lathe removes material from a rotating metal workpiece to create precise cylindrical or conical shapes. This method is ideal for producing:

• Shafts, pins, and bushings

• Threaded fasteners and fittings

• Hydraulic and pneumatic components

• Precision connectors and couplings

Key advantages of CNC turning for metal parts include:
✔ High repeatability for mass production
✔ Complex geometries with live tooling capabilities
✔ Superior surface finishes without secondary processing
✔ Material versatility from aluminum to superalloys
