Application of laser cutting machine in satellite communication field

(Click 88 )

Laser cutting machines, with their high precision and non-contact processing characteristics, have become a key process in the manufacturing of satellite communication equipment. From satellite payloads to core components of ground stations, they rely on them to break through the limitations of traditional processes and provide technical support for the construction of high-speed and highly reliable communication systems.

Satellite laser communication terminals require high-precision optical components, and their structural components have extremely high requirements for dimensional tolerances and surface smoothness. The laser cutting machine achieves complex hollow structure processing on materials such as titanium alloy and aluminum alloy through micrometer level light spots (≤ 30 μ m), with a cutting perpendicularity of ± 0.1 °, avoiding microcracks or deformations caused by traditional mechanical processing, and ensuring the alignment accuracy and stability of the optical system. For example, the onboard laser terminal of Changguang satellite adopts laser cutting technology to process high-temperature resistant brackets, supporting the successful implementation of 100Gbps ultra high speed data transmission experiments.

The optical antenna, heat dissipation module and other components of the satellite ground laser communication ground station need to balance lightweight and high strength. Laser cutting can process irregular holes, grooves, and curved structures on carbon fiber composite materials or ultra-thin metal sheets, increasing material utilization by more than 20% and avoiding damage to coatings caused by traditional stamping.

Satellite communication equipment needs to be compatible with multiple materials such as metals, ceramics, and polymers. For example, laser cutting machines process low loss RF connectors by adapting green light wavelengths to high reflective materials such as copper alloys; Femtosecond laser can etch electromagnetic interference resistant microstructures on silicon nitride ceramic substrates, improving the purity of signal transmission. This type of technological breakthrough helps satellite communication systems operate stably in complex electromagnetic environments.
