- Identical shaft angle-changing structure ensures uniform surface quality on both ends
- Profile supporters on movable heads enhance stability during high-speed operations
- High-Speed Performance Parameters
- Cutting speeds reaching 2840 RPM with 2×3.0kW motor configurations
- Typical machine dimensions of 5800×1800×1500mm (L×W×H)
- Weight capacity around 1750kg for industrial-grade stability
- Material Compatibility
- Designed for aluminum profiles (primary application)
- Effective processing of PVC and UPVC window/door components
- Capable of handling various profile thicknesses and geometries
Operational Advantages in Manufacturing
The implementation of CNC double head cutting technology provides manufacturers with multiple production benefits:
- Enhanced Productivity: The simultaneous dual-head operation dramatically reduces cycle times compared to single-head saws, with some models processing complete window/door frames in under 30 seconds.
- Superior Accuracy: Digital control systems maintain cutting tolerances within ±0.1mm, critical for proper window/door assembly and weatherproofing.
- Flexible Configuration: Programmable cutting angles (45°, 90°, and everything in between) accommodate diverse architectural designs from standard rectangular windows to complex polygonal shapes.
- Reduced Material Waste: Automated measurement and optimized cutting paths minimize profile wastage, improving material utilization rates by 15-20% compared to manual methods.
Industry Applications and Market Trends
These advanced cutting systems have become essential equipment for:
- Aluminum Window/Door Fabrication: Particularly for thermal break and curtain wall systems requiring precise miter joints
- PVC Window Production: Ensuring clean cuts on plastic profiles without deformation or melting
- Hybrid System Manufacturing: Processing combination aluminum-PVC profiles for specialized applications
Current market offerings (as of early 2026) show price ranges from 7,500forbasicmodelsto135,000 for fully automated production-line versions with integrated material handling. Leading manufacturers emphasize CE and ISO certification compliance, reflecting the equipment’s adherence to international safety and performance standards.
Future Development Directions
Emerging innovations in this sector include:
