1、Process Introduction | What can CNC milling solve for you?

3D complex surface: 3-5 axis linkage for one-time clamping to complete multi-faceted processing, eliminating manual flipping errors
High precision positioning: ± 0.01 mm repeatability, hole position, cavity, thread can be directly assembled
Hard material processing: HRC52 quenched CBN high-speed milling, replacing traditional grinding, saving 30% of labor hours
Mirror effect: Ra ≤ 0.4 µ m high gloss blade path, no post-processing required for exterior parts
Small batch fast delivery: 24-hour automatic tool change+online measurement, starting from 1 piece, shipped within 48 hours
