The cutting thickness of a 30,000-watt laser cutting machine varies significantly depending on the material. According to industry technical specifications and measured data, its typical cutting capacity is: carbon steel can reach 80-100mm, stainless steel is about 50-60mm, aluminum alloy is about 40-50mm, and brass is about 25-30mm. The specific cutting effect needs to be adjusted in combination with the equipment configuration and working condition parameters.
Comparison of cutting thickness of different materials
The cutting capacity of a 30,000-watt laser cutting machine has an exponential growth relationship with its power level, which is specifically manifested in the following typical values (under experimental working conditions):
Note: The table data is based on the measured thickness of the 15,000-watt model and is calculated according to the power increase ratio.
Key factors affecting cutting depth
1. Beam quality:
The flat-top beam mode can increase the cutting thickness by 15%-20%, but special optical components are required.
2. Auxiliary system:
The double closed-loop water cooling system can stabilize the temperature fluctuation of the cutting head within ±2℃, ensuring the stability of thick plate cutting.
The high-precision positioning system (repeat positioning accuracy ≤0.03mm) can reduce the inter-layer deviation when cutting thick plates.
3. Process parameters:
For every 10% reduction in cutting speed, the maximum cutting thickness can be increased by 8%-12%.
The carbon steel cutting efficiency is increased by 30% during oxygen-assisted cutting, but the cut oxide layer is thickened by 0.2-0.5mm.
Technical breakthroughs and limitations
1. Latest progress: In 2024, Tianhong Laser's experimental model has achieved continuous cutting of 120mm carbon steel, but the cutting speed is only 1.2m/min.
2. Physical limitations: When cutting carbon steel exceeding 80mm, the laser energy attenuates by 60%, and the groove cutting process needs to be coordinated.
3. Economic considerations: When the cutting thickness exceeds the recommended value, the cutting cost per unit length increases exponentially.
