The working size (marking area) of a fiber laser marking machine depends on the lens configuration and the application requirements. Here’s a breakdown of common working sizes and their typical uses:
1. Standard Working Sizes
| Lens Focal Length | Marking Area (Approx.) | Common Applications |
|---|---|---|
| 110mm (F-theta) | 100mm × 100mm (4" × 4") | Small parts, electronics, jewelry, QR codes |
| 160mm (F-theta) | 150mm × 150mm (6" × 6") | Tools, medical devices, hardware, logos |
| 210mm (F-theta) | 200mm × 200mm (8" × 8") | Automotive parts, industrial labels, larger metal components |
| 300mm+ (F-theta) | 300mm × 300mm (12" × 12") or more | Large industrial parts, aerospace components, batch marking |
2. Extended Working Sizes (Galvo Scanner + XY Motion System)
Dynamic Focus Lens → Can mark on curved or uneven surfaces.
Large-Format Machines → Some systems offer 500mm × 500mm (20" × 20") or even larger areas for sheet metal, pipes, and panels.
3. Key Factors Affecting Working Size
Lens Type: Shorter focal length = smaller area but finer details.
Laser Power: Higher power (20W, 30W, 50W, etc.) allows deeper engraving on metals but doesn’t directly affect marking size.
Software & Galvo Speed: High-speed galvo systems maintain precision even in large areas.
4. Applications by Working Size
Small (100×100mm): Precision marking (PCB, micro parts).
Medium (150×150mm): Tools, medical instruments, serial numbers.
Large (300×300mm+): Automotive VIN plates, industrial machinery, aerospace components.
