Key Features

CNC Servo Length Control – Automatic positioning of the length stop via servo motor, ensuring repeat accuracy of ±0.02 mm for fixed-length cutting.

Dual-Angle Cutting – Quick-switch cutting head supports 45° mitre and 90° square cuts, ideal for corner joints in window, door, and curtain wall profiles.

550 mm High-Performance Blade – Fitted with a premium carbide-tipped circular saw blade (Ø550 × 30 mm bore), delivering clean, burr-free cuts on aluminum, UPVC, and thin-wall steel.

Rigid Machine Body – Heavy-duty welded steel frame with vibration-damping design ensures long-term cutting stability and blade life.

Pneumatic Clamping System – Dual vertical and horizontal pneumatic clamps secure the profile firmly during the cutting cycle, preventing shifting and ensuring cut squareness.

User-Friendly CNC Interface – 7" color touchscreen with intuitive menu; operators can store up to 50 cutting programs with multi-length settings.

Safety & Efficiency – Full-enclosure safety guard with transparent viewing window, automatic blade lubrication mist system, and chip collection drawer.
