Fiber Laser Cutting Thickness Chart for Hong Niu 3015H–8025H Machines (3kW–80kW)
Thickness Capability by Power Range
3kW–12kW Cutting Thickness for Sheet Metal
Low to medium power fiber laser cutting machines (3kW–12kW) are primarily designed for sheet metal processing. These machines are widely used in industries such as electrical cabinets, HVAC, and general fabrication where thin to medium thickness materials dominate.
For this power range, cutting performance focuses on speed, precision, and surface quality rather than maximum thickness.
Typical Thickness Capability (3kW–12kW)
| Power | Carbon Steel | Stainless Steel | Aluminum |
|---|---|---|---|
| 3kW | 8–12 mm | 4–6 mm | 3–4 mm |
| 6kW | 12–20 mm | 8–12 mm | 6–8 mm |
| 12kW | 20–25 mm | 12–16 mm | 8–12 mm |
These machines are ideal for high-speed production of thin sheets, where efficiency and edge quality are more important than cutting thickness.
Key advantages include:
- Fast cutting speed for thin materials
- High precision and minimal deformation
- Low operating cost compared to high power systems
20kW–80kW Thick Plate Cutting Capacity (Up to 100mm)
High power fiber laser cutting machines significantly extend cutting thickness capability. Systems in the 20kW–80kW range are designed for heavy industrial applications, including thick plate processing.
Typical Thickness Capability (20kW–80kW)
| Power | Carbon Steel | Stainless Steel |
|---|---|---|
| 20kW | 30–40 mm | 20–25 mm |
| 30kW | 50–70 mm | 30–40 mm |
| 60kW | 80–100 mm | 50–60 mm |
| 80kW | 100 mm+ | 60–70 mm |
High power systems enable:
- Deep penetration for thick plates
- Reduced cutting time compared to lower power machines
- Replacement of plasma or flame cutting in many applications
However, higher power also requires more precise parameter control and stronger machine structure to maintain stability.
Material-Based Cutting Capability
Carbon Steel vs Stainless Steel Comparison
Different materials respond differently to laser cutting due to their physical and chemical properties.
Carbon steel is easier to cut at greater thickness because oxygen-assisted cutting generates additional heat through oxidation. This improves cutting efficiency and allows deeper penetration.
Stainless steel, on the other hand, requires nitrogen to prevent oxidation, which means the cutting process relies entirely on laser energy. As a result, maximum cutting thickness is lower compared to carbon steel.
Material Comparison
| Material | Assist Gas | Max Thickness (80kW) | Edge Quality |
|---|---|---|---|
| Carbon Steel | Oxygen | 100 mm+ | Oxidized edge |
| Stainless Steel | Nitrogen | 60–70 mm | Bright, clean edge |
This difference is critical when selecting machine configuration and cutting parameters for specific applications.
Aluminum and Copper Cutting Limitations
Aluminum and copper present additional challenges due to their high reflectivity and thermal conductivity.
These materials:
- Reflect a portion of the laser energy
- Dissipate heat quickly
- Require higher power for stable cutting
Non-Ferrous Metal Capability
| Material | Typical Thickness (High Power) | Limitation |
|---|---|---|
| Aluminum | 20–40 mm | High reflectivity |
| Copper | 10–25 mm | Heat dissipation |
Cutting these materials requires careful parameter optimization, including higher power density and precise focus control.
Thickness Optimization Strategy
Matching Machine Model (3015H–8025H) with Thickness
Different machine models are designed for different application ranges. Matching the machine model with material thickness and size is essential for achieving optimal efficiency.
Model Matching Strategy
| Model | Working Area | Recommended Thickness Range |
|---|---|---|
| 3015H / 6015H | Small sheets | 1–25 mm |
| 4020H | Medium plates | 10–40 mm |
| 6020H / 6025H | Large plates | 20–80 mm |
| 8025H | Extra large plates | 30–100 mm+ |
Using a machine with insufficient working area or power can reduce efficiency and increase handling time.
Proper matching ensures:
- Efficient material utilization
- Reduced repositioning
- Stable cutting performance
Power Selection for Industrial Applications
Selecting the correct power level is essential for balancing efficiency, cost, and performance.
Power Selection Strategy
| Application | Recommended Power |
|---|---|
| Sheet metal production | 3kW–12kW |
| Medium plate fabrication | 12kW–20kW |
| Heavy plate cutting | 20kW–30kW |
| Ultra-thick plate cutting | 30kW–80kW |
Higher power is not always better. It should be selected based on actual production requirements to avoid unnecessary energy consumption.
Fiber laser cutting thickness capability depends on a combination of power level, material type, and machine configuration. Hong Niu machines from 3015H to 8025H cover a wide range of applications, from thin sheet processing to ultra-thick plate cutting above 100 mm.
Low power systems are ideal for high-speed sheet metal cutting, while high power machines enable efficient processing of thick plates in heavy industry.
Understanding the differences between materials, especially carbon steel and stainless steel, is essential for selecting the correct parameters and achieving optimal results.
By matching machine models and power levels with specific application requirements, manufacturers can maximize efficiency, improve cutting quality, and reduce overall production costs.
