First, we need to define what is precision. In the fiber laser cutting machine industry, precision usually refers to the gap between the cutting size and the design drawing size. Ideally, this gap should be 0, but due to various factors (including equipment accuracy, process parameters, material properties, etc.), there will always be a certain deviation between the actual cutting size and the design size.

Precision range of laser cutting by fiber laser cutting machine

The precision of laser cutting mainly depends on the accuracy of the cutting equipment and the accuracy of the cutting process. Generally speaking, the positioning accuracy of the most advanced fiber laser cutting machine can reach ±0.05mm, and the repeated positioning accuracy can reach ±0.03mm. This means that ideally, the gap between the cut part size and the design size can be less than 0.05mm, and the gap between the cutting sizes of the same cutting path after repeated cutting can be less than 0.03mm.

However, the actual cutting accuracy will also be affected by some other factors, including the quality of the laser beam, the cutting speed, the nature of the working material, the flow rate and purity of the cutting gas, etc. These factors may cause the actual cutting accuracy to be lower than the theoretical accuracy of the equipment.

The main ways to improve laser cutting accuracy are:

Choose a high-quality fiber laser cutting machine. High-quality cutting machines usually have higher positioning accuracy and repeatability, and have a better balance between cutting speed and cutting quality.

Optimize cutting parameters. Cutting parameters (including laser power, cutting speed, cutting gas flow, etc.) have a great influence on cutting accuracy. By adjusting these parameters, the cutting accuracy can be improved to a certain extent.

Choose appropriate cutting gas. Different materials have different requirements for cutting gas. Choosing appropriate cutting gas can improve cutting quality and thus improve cutting accuracy.

In general, the upper limit of the accuracy of fiber laser cutting machines mainly depends on the accuracy of the cutting equipment and the accuracy of the cutting process. Although in ideal conditions, the accuracy of laser cutting can reach ±0.05mm, it may be affected by many factors in actual operation. By selecting high-quality equipment and optimizing cutting parameters, the cutting accuracy can be improved to a certain extent.
