What is the power of the laser cutting machine?

### Power range and influencing factors of laser cutting machine

As the core equipment of modern manufacturing industry, the power parameters of laser cutting machine are the key indicators that determine the cutting performance. Laser power (in watts,W）Directly affecting cutting ability, efficiency, and applicable material range. This article will analyze the power range, influencing factors, and application considerations of laser cutting machines from a professional perspective, ensuring that the content is rigorous and based on industry standards.

#### Power Range: Diversity from Low to High
The power range of laser cutting machines is extremely wide, mainly depending on the laser type and design goals. Common types include:
- **CO2laser**Power is usually within500Wto6000Wbetween. For example,1500WThe model is suitable for cutting thicknesses less than10mmNon metallic materials such as acrylic or wood, and4000WThe above models are capable of handling20mmThick carbon steel.
- **fiber laser**With high efficiency and beam quality, the power range is wider, from1000Wto20000WEven higher.1000W-3000WThe model is commonly used for thin metal cutting (such as1-6mmStainless steel),8000WThe above models are used for thick plates (such as25mmAlloy steel or high-speed production.
- **Other types**As follows:Nd:YAGLaser, low power（100W-1000W）It is commonly used for precision carving or thin material processing. Overall, the lower limit of power for commercial laser cutting machines is approximately100W(Used for microfabrication), with an upper limit of up to15000WAbove (industrial grade thick plate cutting). It is worth noting that although ultra-high peak power devices (such as pulsed lasers) have high power values, the average power needs to be evaluated in conjunction with the duty cycle.

#### Influencing factors: multidimensional analysis of power demand
The selection of laser power is not fixed and requires comprehensive consideration of the following factors:
1. **Material Properties**The reflectivity, melting point, and thermal conductivity of materials directly affect power demand. Highly reflective materials such as aluminum or copper require higher power (usually2000WTo overcome reflection losses; And low melting point materials (such as plastics) are500W-1000WEfficient cutting can be achieved. Material thickness is a key variable - according to empirical formulas, cutting thickness（mm）Corresponding to the required power（kW）Positive correlation. For example, cutting10mmCarbon steel needs to be at least2000WBut20mmThick plates are required4000WThe above.
2. **cutting parameters**The cutting speed is inversely proportional to the power. High power (such as6000W）Allow high-speed cutting (accessible)30m/min）Improve efficiency; On the contrary, at low power, the speed needs to be reduced to ensure cutting quality. In addition, the beam quality (such asMOptimizing the power utilization efficiency of the focusing system and improving the square value, inferior optical components will increase the actual power demand.
3. **Application scenarios**Industrial production lines emphasize high power (≥)8000W）To cope with continuous operations; Small and medium-sized enterprises may choose1500W-3000WBalancing cost and performance for aircraft models. Safety standards (such asIEC 60825）Also limit the maximum power to prevent radiation hazards.

#### Conclusion: Practical suggestions for optimizing power selection
The power range of laser cutting machine is from100Wto20000WAbove, covering the full spectrum of requirements from microfabrication to heavy industry. When selecting, it is necessary to strictly evaluate the material, thickness, and process objectives to avoid cutting failure caused by insufficient power or energy waste caused by excessive power. It is recommended to determine the optimal power through simulation software or professional consultation, and combine it with maintenance plans (such as regular calibration of optical paths) to ensure long-term stability. In the future, with the development of fiber laser technology, high-power equipment（>10000W）It will become more popular, but the core principle remains unchanged: power is a tool, not an end in itself, and the full potential of laser cutting can only be unleashed through reasonable matching of applications.
