Product Overview
Our CNC turning services deliver high-precision cylindrical components for industries demanding rotational symmetry and tight tolerances. Using Swiss-type CNC lathes with live tooling and sub-spindles, we produce parts from aluminum 6061, stainless steel 304 and PEEK with ±0.005 mm dimensional accuracy. From transmission shafts to precision bushings, our solutions combine complex geometries (multi-diameter shafts with keyways) with cost-effective mass production (10,000–1,000,000 parts/year) supported by automated quality control.

Features
Extreme precision turning — high-speed spindles and closed-loop coolant systems maintain consistent temperature for roundness down to ±0.002 mm on small shafts and ±0.01 mm on larger flanges. Multi-axis turning with live tooling creates helical grooves, cross-drilled holes and fine features in a single setup.
Material diversity — metals (aluminum, stainless steel, brass, titanium) and engineering plastics (PEEK, POM, Nylon), with minimum feature size of 0.1 mm. High-temperature alloys (Inconel 718, Hastelloy X) handled with high-pressure coolant for aerospace applications.
Automated production — bar feeder systems enable continuous production of long-shaft parts (length-to-diameter ratio up to 30:1), with automatic tool changers and smart scheduling keeping lead times consistent (3–15 days) and reducing downtime.
Surface treatments — type II/III anodizing (12–25 μm), electroplating (gold, nickel, chrome) and PTFE coating (low friction) for functional surfaces. Medical-grade electropolishing and biocompatibility testing available on request.
Applications
Automotive — transmission shafts, fuel injector nozzles and CV joint components with splined features.
Medical — surgical instrument components, orthopedic pins and catheter guide wires, with medical-grade finishing available on request.
Aerospace — turbine compressor blades (±0.005 mm profile accuracy), landing gear actuator rods and hydraulic valve spools.
Industrial — hydraulic cylinder rods, bearing races with tight runout control, and precision lead screws.
Custom Service
Design for Manufacturability (DFM) support — free analysis of threaded features (ISO metric, UN imperial, ACME), chamfer angles and undercut dimensions to optimize part geometry for turning and reduce cycle time.
Complex geometry solutions — micro-turning (features ≤0.5 mm) and deep hole drilling (aspect ratio up to 20:1) for fuel injectors and optical components.
Full traceability — QR-code labeling linked to CMM inspection reports, material certificates (EN 10204 3.1) and process parameters for automotive and aerospace audits.
