As a high-precision and high-efficiency processing equipment, fiber laser cutting machine is widely used in various manufacturing fields. Its cutting accuracy is a key factor affecting product quality and processing efficiency. This article will discuss the accuracy of fiber laser cutting machine and its influencing factors.

Accuracy of fiber laser cutting machine

The accuracy of fiber laser cutting machine mainly includes position accuracy, shape accuracy and size accuracy. Position accuracy refers to the ability of the cutting head to control the position of the material during the cutting process, shape accuracy refers to the ability of the laser beam to change the shape of the material, and size accuracy refers to the accuracy of the size of the cut product.

Factors affecting the accuracy of fiber laser cutting machine

Laser beam quality

The quality of the laser beam is a key factor affecting the accuracy of the fiber laser cutting machine. The energy distribution, beam diameter, and beam quality of the laser beam will affect the cutting accuracy. Generally speaking, a laser beam with a high energy density can improve the cutting speed and accuracy.

Focusing lens and reflector

The performance of the focusing lens and reflector will also affect the accuracy of the fiber laser cutting machine. If the surface of the focusing lens and the reflector is contaminated, scratched or deformed, the focusing position of the beam will deviate, thus affecting the cutting accuracy.

Transmission system

The transmission system is an important part of the fiber laser cutting machine. If the transmission system is not accurate or has errors, the moving trajectory of the cutting head will be inaccurate, thus affecting the cutting accuracy.

Control system

The control system is the core of the fiber laser cutting machine. It controls the moving trajectory and power of the laser beam. If the control system is not accurate or has errors, it will cause deviations in the cutting shape and size.

Material factors

Material factors are also one of the factors affecting the accuracy of the fiber laser cutting machine. The thickness, composition, thermal conductivity, etc. of the material will affect the cutting effect of the laser beam on the material. For example, thicker materials require higher laser power and longer cutting time to complete the cutting.

Measures to improve the accuracy of fiber laser cutting machines

Select high-quality lasers and high-precision transmission systems to ensure the quality of the laser beam and the accuracy of the moving trajectory of the cutting head. Regularly check and maintain optical components such as focusing lenses and reflectors to ensure that their surfaces are clean, scratch-free and deformed. Use advanced control system technology and sensor technology to improve the accuracy and response speed of the control system. According to different material types and thicknesses, select appropriate laser power, cutting speed, auxiliary gas and other parameters to ensure cutting effect and quality. Strengthen process research and testing, and continuously optimize process parameters and operating procedures to improve the processing accuracy and efficiency of laser cutting machines.

In short, improving the accuracy of fiber laser cutting machines requires multiple aspects, including laser beam quality, transmission system, control system, material factors, etc. Only by comprehensively considering these factors and taking corresponding measures can the processing accuracy and efficiency of fiber laser cutting machines be improved to meet the needs of various manufacturing fields.
