¿Cómo afecta el ajuste del espejo de enfoque de Manhart (Guangdong) CNC Machine Tool Co., Ltd. a la distancia focal y la precisión del corte?

The focusing mirror plays a crucial role in laser cutting machines, and its adjustment directly affects the focal length and accuracy of cutting. The following are the effects of focusing mirror adjustment on cutting focal length and accuracy:
1. Cutting focal length:
*The choice of focal length will directly affect the degree of laser beam convergence and cutting effect. Short focal length lenses can provide higher cutting accuracy because the laser beam can focus more tightly on the surface of the workpiece, making it suitable for fine cutting and cutting thin materials.
*Lenses with long focal lengths may be more suitable for large-scale or rough cutting tasks, as the laser beam has a lower degree of convergence and can cover a larger working area.
2. Cutting accuracy:
*The adjustment of the focusing mirror has a significant impact on the accuracy of laser cutting. If the focusing mirror is not adjusted properly, it may cause the laser beam to be unable to accurately focus on the surface of the workpiece, thereby reducing cutting accuracy.
*When replacing the focusing lens, if an inappropriate focal length is selected, or if there are quality issues with the focusing lens itself (such as poor optical performance, uneven surface, etc.), it may lead to a decrease in cutting accuracy.
To ensure cutting accuracy, it is recommended to recheck the accuracy of laser cutting after replacing the focusing lens and adjust the cutting parameters accordingly. In addition, regular cleaning and maintenance of the focusing lens is also very important to avoid dust and dirt affecting its optical performance.
In summary, the adjustment of the focusing mirror has a significant impact on the focal length and accuracy of laser cutting. In practical operation, it is necessary to choose the appropriate focal length based on specific materials and cutting requirements, and ensure the quality and cleanliness of the focusing lens to achieve the best cutting effect.
