Latest company news about How to Choose the Right Power of Fiber Laser Cutter for Different Thickness Metals  | HE LASER

Fiber laser cutters are widely used high-precision cutting tools in metal processing. However, choosing the proper power is a key factor for different thickness metals. The right power selection ensures cutting quality and efficiency while avoiding problems caused by excessive or inadequate energy input. This blog provides a comprehensive guide on how to choose the right power of a fiber laser cutting machine for different thickness metals, considering important factors such as material thickness, cutting speed, and cutting quality requirements. By making informed power selections, efficient, precise, and non-destructive metal cutting can be achieved, as well as highlight common misconceptions and offer guidance to avoid them.

1. Determine the Metal Thickness Range:

Start by identifying the range of metal thicknesses you typically work with. Different power levels are suitable for different thickness ranges. Fiber laser cutters are usually classified into three power categories: low (up to 1 kW), medium (1 kW to 4 kW), and high (over 4 kW). Generally, thicker materials require higher power. This is because thicker materials necessitate additional energy to overcome thermal conduction and achieve melting.

Here are typical power ranges for common metal materials:

2. Considerations for Cutting Speed:

Cutting speed is another important factor influencing power selection. Generally, higher power fiber laser cutters can achieve faster cutting speeds, Additionally, increasing cutting speed can help reduce the heat-affected zone and deformation of materials which can significantly improve productivity. Thicker metals typically require more power to achieve faster cutting speeds. Evaluate the desired cutting speed for your production needs to determine the power level that can meet those requirements.

For cutting different material thicknesses, appropriate parameters should be chosen based on the relationship between cutting speed and power.

 

3. Material Type:

Different metals have varying reflective properties, which can impact the effectiveness of laser cutting. For example, stainless steel reflects more laser energy compared to carbon steel. Higher power fiber laser cutters are generally more suitable for materials with higher reflectivity, as they can overcome the reflective losses more efficiently.

 

4, Cutting Quality Requirements:

Cutting quality requirements also affect power selection. Different cutting quality standards, such as kerf width, edge quality, and kerf smoothness, often require different power levels to achieve. For instance, higher power is needed to ensure cutting quality when stringent cutting quality is demanded.

 

5. Budget and Cost Considerations:

The power level directly influences the cost of a fiber laser cutter. Higher power machines tend to be more expensive upfront, but they can offer better performance and productivity for thicker materials. Consider your budget and balance it against the expected cutting requirements to find the most cost-effective solution.

 

6. Maintenance and Operating Costs:

Higher power fiber laser cutters may require additional maintenance and have higher operating costs due to increased energy consumption. Assess your ability to handle maintenance tasks and the long-term financial implications when deciding on the power level of the fiber laser cutter.

 

7. Consult with Experts:

If you are unsure about the appropriate power level for your specific application, it is advisable to consult with experts or manufacturers who have experience working with fiber laser cutters. They can provide valuable insights and recommendations based on your specific requirements.

 

Avoiding Common Misconceptions:

Q: Is higher power always better?

A: No, higher power is not always better. Using excessive power for thin materials can cause excessive heat, leading to material deformation or a wider heat-affected zone.

 

Q: Can low power handle thick materials through multiple passes?

A: While low power can eventually cut thick materials through multiple passes, it is time-consuming and can result in uneven cuts. It is best to choose the appropriate power level for efficient cutting.

 

Conclusion:

Choosing the correct power level for a fiber laser cutter for different thickness metal is essential to optimize cutting efficiency and productivity. Consider the metal thickness range, cutting speed, material type, budget, and maintenance costs when making your decision, and avoiding common misconceptions. Consulting with experts can also help in determining the most suitable power level for your specific needs. With careful consideration, you can ensure that your fiber laser cutter performs optimally for your desired metal cutting applications.
