CNC Machining

26 UNITS · MAX 4 METRES

Our CNC machining department operates 26 machines across two capacity ranges: 22 units dedicated to small-to-medium precision parts, and 4 specialised units for large components above 500mm — including chambers, machine bases, and structural frames.

Machines are strictly grouped by material type. Cross-material machining is not permitted, ensuring zero contamination risk and full Copy Exact compliance.
