How To Find The Zero Focus of The Laser Head of The Laser Cutting Machine?

1.Introduction to the cutting head of laser cutting machine：

In a recent breakthrough in laser cutting technology, researchers have discovered a new method to determine the optimal focus position for laser heads. This finding is crucial for adjusting the cutting process and achieving the most concentrated laser energy.

Traditionally, many laser heads are set to a focus position of 0 in the parameters, but this may not be accurate due to factors such as focusing lenses. As a result, there can be positive and negative deviations that impact the cutting effect and overall quality. This could also explain why some users may not achieve optimal results when using parameters provided by others.

To address this issue, researchers have developed a simple yet effective method to find the ideal focus position. By using a 1mm stainless steel plate and drawing multiple line segments, they were able to test different focus positions and determine the one that resulted in the thinnest and burr-free cuts. This position was identified as the 0 focus of the laser head.

2.About the use of laser cutting head

Next, use the following formula to debug the process according to this focus position:

0 focus is a positive number, and negative number + positive number = correct focus position when cutting with negative focus:

0 focus is a negative number, and negative number + negative number = correct focus position when cutting with negative focus.

Moving forward, researchers have developed a formula to help users adjust their cutting process based on this optimal focus position. By following this formula, users can achieve precise and efficient cutting results, whether using positive or negative focus positions.

This groundbreaking discovery is expected to revolutionize the field of laser cutting and improve the accuracy and quality of cutting processes. Stay tuned for more updates on this exciting development in laser technology.
