Core Features
Every feature is engineered with a name, a purpose, and measurable impact — the TRUMPF-inspired approach to systematic innovation.
Capillary Precision System (CPS)
Proprietary precision support and beam control system for capillary tubes as small as φ3mm. Ensures zero deformation during cutting.
Beam Quality Control (BQC)
Advanced optical path calibration maintains consistent beam quality across the entire cutting envelope for ±0.03mm repeatability.
Clean-Cut Edge
Optimized cutting parameters produce burr-free edges requiring no secondary finishing –ready for immediate assembly or welding.
Auto-Focus
Dynamic focus adjustment compensates for material variations in real-time, ensuring consistent cut quality across different tube batches.
Micro-Feed System
Precision servo-driven feeding mechanism handles ultra-thin wall capillary tubes without crushing or deformation.
Trusted by Manufacturers Worldwide
