Comprehensive understanding of the coil fed laser cutting machine

Why Do You Need a Coil Fed Laser Cutting Machine?

A coil fed laser cutting machine is the ideal solution for manufacturers seeking higher efficiency, continuous production, and lower material cost in modern sheet metal processing.
Compared with traditional sheet cutting, a coil sheet metal laser cutting machine enables automatic feeding from metal coils, reducing manual handling, minimizing material waste, and significantly improving productivity.

The complete working process of a coil sheet laser cutting machine includes:

1. Loading trolley

2. De-coiler

3. Levelling unit

4. Fiber laser cutting unit

5. Transportation table

6. Manual unloading

This fully integrated workflow makes the coil fed laser cutting machine a key solution for high-volume, flexible, and automated sheet metal cutting lines.

Complete Process & Core Components of Coil Fed Laser Cutting line

1. Heavy-Duty Loading Trolley (Up to 15T)

The loading trolley is designed to transport metal coils safely and efficiently to the decoiler.

Advantages:

• Maximum loading capacity up to 15 tons, suitable for heavy metal coils

• Hydraulic motor driving system ensures smooth movement

• Hydraulic cylinder lifting system aligns the coil precisely with the decoiler main shaft

• Reduces labor intensity and improves loading efficiency

• Enhances safety for coil sheet metal laser cutting machine operations

2. High-Precision De-Coiler System

The decoiler is a critical unit for any coil laser cutting machine, directly affecting feeding stability and cutting accuracy.

Structural Advantages:

• Main frame made of square tubes, Q235 steel plates, and 45# steel

• Fully stress-relieved by annealing to prevent deformation

• Front and rear bearing holes bored in one process to ensure spindle concentricity and zero radial runout

Key Components:

• Spindle: Made of 45# seamless steel pipe, quenched and tempered for high strength

• Hydraulic expansion system: Connecting-rod type push-pull expansion drum

• Pressing device: Polyurethane-coated pressing wheel, cylinder-controlled support arm

• Material supporting system: Support arms and rolling cylinders driven by servo motor and reducer

Thickness & Power Matching:

• Standard coil thickness: 1–3mm, suitable for 3000W coil sheet laser cutting machine

• Heavy-duty applications: 3–6mm coil thickness, supported by reinforced decoiler design

• Recommended laser power: 6000W or 12000W fiber laser, ideal for thick coil sheet metal cutting

This makes the system highly adaptable for different coil fed laser cutting machine applications.

3. High-Accuracy Levelling Unit (17-Roller Structure)

To ensure flat and stress-free sheet feeding, the leveling unit plays a vital role in the coil sheet metal laser cutting machine.

Technical Advantages:

• 17 leveling rollers (8 upper + 9 lower) for superior flatness control

• Rollers driven by servo motor and precision gearbox

• Roller material: alloy steel with quenching, tempering, high-frequency hardening, and hard chrome plating

• Planar correction accuracy: ≤ 1.5mm/㎡

This ensures excellent sheet flatness before entering the fiber laser cutting area, greatly improving cutting quality and consistency.

4. Fiber Laser Cutting Machine – Stable & Compact Design

The laser cutting unit is specially designed for continuous coil feeding and high-speed processing.

Advantages:

• Compact structure with minimal footprint, ideal for factories with limited space

• Modern and clean appearance, suitable for automated production lines

• Designed specifically for coil laser flexible cutting machine applications

Machine Bed Structure:

• Dual integrated welding bed design

• Entire bed welded as one piece and stress-annealed

• Manufacturing process:
  Welding → Stress annealing → Rough machining → Finishing machining

• Effectively eliminates internal stress and ensures long-term stability

Key Benefits:

• Excellent vibration resistance during high-speed cutting

• Long-term precision retention

• Ideal for continuous operation of coil fed laser cutting machines
