CNC Machining Service

Precision Machining for Complex Parts

We provide CNC machining services for prototypes, low-volume production, and batch manufacturing.

CNC Machining Core Process

Process	Equipment Capacity	Precision
CNC Milling	Up to 800 × 500 × 500 mm	±0.01mm
CNC Turning	Depending on part geometry	±0.005mm
CNC Turning-Milling Hybrid	Reduced repositioning and improved machining efficiency	Based on part requirements

Different machining processes are selected according to part complexity, dimensional requirements, and production efficiency.
