Machine Bed: Plate-Welded vs. Tube-Welded
The stability of the machine bed directly determines the cutting accuracy and the lifespan of the fiber laser machine. For a high-performance 2060 model, the bed structure is the most critical component.
Heavy-Duty Plate-Welded Bed
- Aviation-Grade Stability: Welded with 12mm-16mm high-tensile carbon steel plates. The massive weight (1.5 tons+) effectively absorbs vibration.
- Stress-Relief Process: Undergoes 600°C high-temperature annealing and 24-hour furnace cooling to ensure zero deformation for 20 years.
- Precision Milling: All mounting surfaces are processed by a 5-axis CNC Gantry Milling machine in a single setup.
Tube-Welded Bed
- Lightweight Structure: Constructed from hollow square tubes. Prone to resonance during high-speed acceleration.
- Short Lifespan: Material is thinner and may warp after 1-2 years due to thermal stress and kinetic inertia.
- Low Accuracy: Hard to maintain sub-zero tolerances during heavy plate cutting or high-power operations.
Why it matters: A plate-welded bed provides the "rigidity" required for fiber lasers over 3000W. Without it, the machine will lose its positioning accuracy within years, leading to wasted materials and high maintenance costs.
Frequently Asked Questions (FAQ)
Q1: What is the maximum metal thickness the Laser machine can cut?
The cutting capacity depends on the laser power source. For example, a 3kW source can cut up to 20mm Carbon Steel and 10mm Stainless Steel. With 12kW, you can cut up to 40-50mm Carbon Steel. We will recommend the optimal power based on your specific needs.
Q2: Why is the Plate-Welded bed better than a Tube-Welded bed?
Plate-welded beds provide much higher rigidity and weight (4.5 tons+ for the 2060), which is essential for absorbing vibrations during high-speed acceleration. It prevents deformation over time, ensuring the machine maintains ±0.03mm accuracy for over 20 years.
Q3: What CNC software does the machine use? Is it easy to learn?
We use the industry-standard CNC control system. It is highly intuitive and supports DXF, AI, and PLT files. Most operators can master the basic cutting process within 2 days of our online or on-site training.
Q4: How long is the delivery time and warranty?
Standard production time is 20-30 working days. We provide a 24-month warranty on the entire machine (excluding consumables) and lifetime technical remote support.
Q5: Do you provide on-site installation and training?
Yes! We have a global team of engineers. We offer detailed installation videos and manuals, and we can also dispatch engineers to your facility for setup and comprehensive staff training.
