Our CNC Mill-Turn Machining Service Process
We follow a structured, quality-driven process to ensure every component meets your exact specifications – from initial design review to final delivery.
1. Design
Our engineering team reviews your CAD files to optimize for manufacturability, reduce costs, and ensure tolerance feasibility.
2. Prototyping
We produce a small batch of prototypes to validate design, test fit/function, and confirm machining parameters.
3. Machining
Full production using our advanced mill-turn equipment – single-setup machining eliminates alignment errors.
4. Inspection
100% in-process and final inspection using CMMs, optical comparators, and surface finish testers.
5. Finishing
Secondary processes (anodizing, plating, heat treatment) to meet material and surface requirements.
6. Delivery
Custom packaging and on-time delivery – global shipping with full traceability documentation.

Mill -Turn Machining FAQs
What is turn-mill machining?
Turn-mill machining, also known as multi-tasking machining, is an advanced manufacturing process. It combines turning and milling operations on a single machine platform. This allows for complete machining of complex parts in just one setup, significantly enhancing efficiency and precision for complex CNC parts.
What are the specifications of your turn-mill centers
Our multi-tasking machining centers are equipped with full 5-axis simultaneous machining capability, high-speed live tooling spindles (e.g., 12,000 RPM), and large travel ranges (e.g., X: 600mm) to handle complex, medium-sized parts in one setup.
What are the specifications and brands of your turn-mill machining centers?
Our workshop is equipped with modern multi-tasking CNC machines from leading brands like Mazak or DMG MORI. They feature high-power live tooling, Y-axis capability, and automated tool changers, enabling efficient production of complex parts from bar stock or blanks in a single chucking.
How to guarantee part quality & what measurement tools do you use?
We ensure quality through a rigorous process: First-Article Inspection using CMM (Coordinate Measuring Machine) and optical comparators for critical dimensions. For ongoing production, we perform statistical process control (SPC). This commitment to precision measurement guarantees every part meets your print specifications.
What is your typical lead time for a batch of custom machined parts?
For standard projects, our typical lead time ranges from 2-4 weeks after final design approval. We offer accelerated rapid prototyping services for urgent needs. You can get an accurate production timeline estimate instantly through our online quoting system by uploading your drawings.
Do you provide sub-assembly or finishing services beyond machining?
Yes. We offer value-added services like post-machining finishing (anodizing, polishing), component assembly, and kitting. This turns your machined parts into ready-to-use sub-assemblies, simplifying your supply chain.
