Reliable CNC turning Services: Custom Parts, Flawless Execution

At Polestar Metal, we transform your concepts into high-precision realities. Our advanced CNC turning services deliver custom machined components with unmatched accuracy, consistency, and quality for every order. As a specialized CNC turning services provider, we ensure that every part leaving our facility meets the most demanding specifications, leveraging state-of-the-art equipment and decades of machining expertise.

What is CNC Turning?

CNC turning is a subtractive manufacturing process where a rotating workpiece is fed against a stationary cutting tool to produce cylindrical components with high precision. Controlled by computer numerical control (CNC), the operation achieves tolerances as tight as ±0.005 mm and surface finishes down to Ra 0.4 µm. Typical turned parts include shafts, bushings, and threaded fasteners, with capacity for diameters up to 300 mm and lengths exceeding 600 mm. Multi-axis CNC turning centers enable simultaneous milling and drilling operations, reducing secondary processing requirements for complex geometries.

Uncompromising Quality in Every Material:
