Tube processing line i25A

Case Study: High-Precision Automated Laser Solution for Hyundai Motor Company
As a global leader in automotive innovation, Hyundai Motor Company required a high-capacity, automated tube processing line for instrument panel structures. The goal was to replace traditional methods with a fiber laser system that could feed directly into robotic bending and pressing cells.


The Challenge: Automotive-Grade Requirements
• Scale: Massive, high-speed production of 1.5m finished parts from 8m raw tubes.
• Precision: Perfect circularity and burr-free edges to ensure fitment in safety-critical assemblies.
• Dimensions: Specific diameter range of 25A – 75A.
• Workflow: Dynamic integration where robotic arms must grab the part during the cutting process to ensure zero-drop damage and perfect orientation for subsequent bending.
• Throughput: Rotation speeds exceeding 100 r/min.


The Golden Laser Solution: Integrated i25A Laser Tube Cutting System
Golden Laser engineered a customized i25A 8-Meter Fiber Laser Tube Cutting Line integrated with advanced robotics to meet these rigorous Tier-1 standards.


1. Customized i25A Tube Cutting Platform
We deployed a specialized 8m-bed P2080A machine equipped with an ultra-fast automatic bundle loader. The system handles the heavy 8m semi-finished pipes with a high-dynamic response, achieving the requested 100 r/min rotation speed while maintaining ultra-tight tolerances.
2. Synchronized Robotic Grab-and-Cut
• To maintain the highest accuracy for downstream processing, the receiving end features a high-speed robotic arm. Unlike standard systems where parts fall into a bin, this robot clamps the tube before the final cut is completed. This ensures:
• Zero Burrs: Perfect mechanical stability during the final severing.
• Perfect Circularity: No deformation from gravity or impact.
• Ready for Bending: The robot maintains the orientation for immediate transfer to the punching and bending stations.


3. 3D Robotic Drilling & Finishing
For complex elbow components, a 3D laser robot was integrated to perform high-precision hole drilling on curved surfaces, replacing multiple manual drilling jigs with a single, flexible automation cell.


Key Performance Results
• Material Yield: Optimized 8m to 1.5m nesting to minimize scrap
• Edge Quality: Burr-free, perfect circle finish ready for welding
• Process Speed: 100 r/min chuck rotation
• Workflow: Fully automated: Loading → Laser Cutting → Robotic Transfer → Bending
