Core Configurations – Built for Precision Sheet Metal Cutting
We integrate top components to ensure stable, accurate cutting on sheet metal day after day.
Premium Laser Source
IPG, Max, or Raycus fiber laser. High efficiency and excellent beam quality (M² < 1.1) deliver clean, narrow kerfs.
High‑Rigidity Welded Bed
Stress‑relieved and annealed. Finite element analysis (FEA) minimizes deformation during high‑speed sheet traversal.
Smart Cutting Head
Auto focus, collision protection, and real‑time gap sensing. Perfect for thin and thick sheet metal.
Industrial CNC Control
CypCut or Beckhoff with intuitive sheet nesting software. Supports DXF, DWG, and AI files. Nesting can reduce material waste by up to 20%.
