Selecting the right fiber laser cutting machine is essential for achieving high productivity, excellent cutting quality, and long-term cost efficiency. One of the most common questions customers ask is:
“How thick can a fiber laser cutting machine cut?”
The answer depends on several factors, including laser power, material type, assist gas, and the required cutting quality. For industrial manufacturers, the most important reference is not the machine’s extreme cutting capability but its recommended cutting thickness for continuous batch production.
This guide will help you understand the recommended cutting capacities of different laser power levels so you can choose the best solution for your business.
Recommended Cutting Thickness for Continuous Batch Production
The following data is based on continuous batch production of carbon steel, ensuring stable cutting quality, high efficiency, and reliable machine performance.
| Laser Power | Recommended Continuous Cutting Thickness | Typical Applications |
|---|---|---|
| 1500W | Up to 12 mm | Sheet metal fabrication, kitchen equipment, advertising signs, light industrial manufacturing |
| 3000W | Up to 16 mm | Machinery manufacturing, metal furniture, construction materials, agricultural equipment |
| 6000W | Up to 20 mm | Steel structures, engineering machinery, industrial fabrication, medium-thick plate processing |
| 12000W | Up to 30 mm | Heavy-duty manufacturing, large-scale production, thick carbon steel processing |
| 20000W | Up to 45 mm | Shipbuilding, mining equipment, bridge construction, heavy industrial applications |
ملاحظة: These thickness values refer to the recommended maximum thickness for continuous batch production of carbon steel. The actual cutting capacity may vary depending on the material type, assist gas (oxygen or nitrogen), laser source configuration, and the desired edge quality. Under specific conditions, thicker materials may be cut, but cutting speed and surface finish may be reduced.
