I. Function & Workflow
Core Task: Automatically processes metal coils (steel, aluminum, copper) into flat, dimensionally accurate rectangular sheets, replacing manual cutting to improve precision and efficiency.
Workflow:
`Loading → Uncoiling → Leveling → Feeding → Lengthwise Cutting → Stacking`
Fully automated operation requiring only 1-2 operators, reducing labor costs by 60%+.
