- Structure: Gantry type with crossbeam movement, A/C dual rotation axes, cutting head with n×360° infinite rotation, supporting normal cutting
- Workbench: Rotating exchange table, parallel loading and unloading, efficiency increased by ≈50%
II. Key Technical Parameters (Core Indicators)
- Positioning Accuracy: ±0.03 mm
- Repeat Positioning Accuracy: ±0.02 mm
- Cutting Accuracy: ±0.1 mm (for complex curved surfaces)
- Heat-Affected Zone: ＜0.1 mm, no burrs or deformation on the edge
- Applicable Materials: 1500MPa hot-formed high-strength steel, carbon steel, stainless steel, aluminum alloy, plastic composite parts
- Linkage Performance: X/Y/Z/A/C five-axis linkage, acceleration of 1.2G, speed 30%–50% higher than the industry average
III. Core Advantages
1. Mold-Free Flexible Production: No blanking mold required, offline programming, and model change only needs path adjustment; the development cycle is reduced from several months to several weeks, and the comprehensive cost is reduced by ≈40%.
2. High-Strength Steel Adaptability: Non-contact cutting solves the problem of springback deformation of 1500MPa hot-formed steel, with a pass rate of nearly 100%.
3. All-Round for Complex Curves: One-time clamping to complete hole cutting, trimming, and corner cutting for automotive A/B pillars, door sills, anti-collision beams, battery pack casings, interior and exterior decorations, etc.
4. Intelligent & Stable: Standard with remote operation and maintenance + fault early warning, reducing downtime by ≈80%; high-strength bed, with precision attenuation of ＜0.01 mm in 5 years.
IV. Typical Application Scenarios
- Automotive Manufacturing: Hot-formed structural parts (A/B pillars, door sills, anti-collision beams), battery pack casings, 3D interior and exterior parts
- New Energy: Battery pack trays, cell protective casings, special-shaped cutting of hydrogen storage tanks
- Others: Sports equipment, special-shaped household appliance parts, 3D processing of precision molds
V. Equipment Value Summary
With high precision, high efficiency, and high flexibility, Dinai Five-axis Laser Cutting Machine replaces traditional stamping + trimming molds. It is especially suitable for the production of automotive and new energy parts with multiple varieties, small batches, and rapid iteration, and is the core equipment for intelligent manufacturing upgrading.
