Precision CNC Turning Services

Years of development, driven by the need to meet diverse product design requirements, have led us to continuously upgrade our equipment, now covering nearly all types of turning machines. We not only pursue perfect roundness and stringent dimensional tolerances (±0.005mm), but also integrate complex multi-step processes into a single setup through multi-axis mill-turn technology and Swiss-type precision lathes. This significantly enhances positional accuracy—such as concentricity and perpendicularity—while drastically reducing lead times. We transform your 3D models into complex components with tight tolerances, excellent surface finishes, and repeatable quality, making us the ideal choice for prototypes, functional parts, and low-to-medium volume

CNC Lathe

Stable and efficient — handles all types of rotational parts.

Turn-Mill Composite Lathe

Turn-mill complex in one setup — simplifies complex parts.

Swiss-type CNC lathe

Ultra-precision specialist — excels at slender shafts and micro parts.

Ideal for machining the vast majority of rotationally symmetric parts such as drive shafts, screws, flanges, and bearing sleeves.

Equipped with a live tool turret and spindle indexing (C-axis) capability. The rotating tools enable milling, drilling, and tapping operations, allowing multiple processes to be completed in a single setup.Commonly used for machining drive shafts, steering knuckles, optical lens barrels, sensor housings, artificial joints, and general mechanical components.

The spindle moves along the Z-axis, feeding the bar stock while tools are radially arranged. This enables ultra-high precision and continuous one-pass machining of complex features.Complete multiple operations in a single setup — including external turning, drilling, tapping, milling flats, knurling, etc. — avoiding cumulative errors caused by multiple setups. This is widely used in the processing of precision components for optics, microelectronics, telecommunications, and medical devices, such as precision drive shafts, artificial joints, titanium alloy insertion needles, and similar parts."
