Process Integration & Post-Machining Capabilities
Liaoyuan offers
integrated Machining Services, combining turning with additional operations such as:
- Grinding, Milling, Boring, and Drilling, and Tapping
- Heat Treatment (Quenching & Tempering)
- Surface Coating ( Anti-Corrosion Treatment: e.g. Zinc Spraying, Painting)
This integration streamlines your supply chain, shortens production lead time, and ensures consistency across every process.
Every CNC turning operation is backed by Liaoyuan’s in-house
quality assurance system, featuring advanced CMM inspection, non-destructive testing, and dimensional verification after each critical stage. Our inspection workflow guarantees full traceability, dimensional accuracy, and superior product integrity.
