Showcase of Complex CNC Machining Turning and Milling Combination
We machine a comprehensive range of structural and high-conductivity metals to exact specifications. From lightweight aluminum and rigid stainless steels to highly challenging materials like high-conductivity pure copper . Our advanced multi-axis milling centers ensure exceptional surface finishes and tight tolerances for your most critical load-bearing or thermal management components.
Achieving tight tolerances on polymers requires specialized tooling and strict thermal control. We expertly mill a wide spectrum of engineering plastics—including POM (Delrin), PEEK, Nylon, and PTFE. Our specialized plastic milling process delivers stress-free, burr-free components that are ideal for medical devices, electronics insulators, and lightweight fluid handling applications.
For components operating in extreme environments, standard materials often fall short. Our facility is fully equipped to process hard-to-machine superalloys like Inconel and Hastelloy, as well as specialized composites like G10/FR4. We provide robust, high-precision milling solutions designed to withstand extreme temperatures, corrosion, and wear in the aerospace, defense, and energy sectors.

5-Stage Mill-Turn Workflow & Mill Machine Definition of Quality
Stage 1
Raw Material Verification
MTR verification and incoming inspection.Conduct 100% visual and dimensional inspections of raw material billets, and require the material supplier to provide material test reports to ensure supply chain compliance.
Stage 2
Integrated Mill-Turn Setup
Design for Manufacturing (DFM) review & programming. We leverage advanced 5-axis/9-axis configurations to eliminate redundant setups and optimize “Done-in-One” CNC milling manufacturing for maximum coaxial precision.
Stage 3
High-Precision Inspection
Real-time Mill-Turn processing monitoring. Automated CMM inspection is conducted every 50 parts to verify dimensional stability and maintain tight tolerances of ±0.005mm, ensuring we define milling excellence in every batch.
Stage 4
Post-Machining & Finishing
Surface finish audit & ultrasonic cleaning.
Precision deburring and roughness inspection up to Ra 0.2μm (8μin) for flawless surface integrity.
Stage 5
Final AQL 0.65 Audit
Final quality verification & global delivery.
Strict AQL 0.65 sampling with full traceability (MTR + QC reports) and ISO-certified shipping Pass rate: 99.8%.
