Does the mirror laser drilling machine have a high edge崩边 rate?

Working principle of the mirror laser drilling machine

The mirror laser drilling machine, as the name suggests, uses a high-energy laser beam emitted by a laser source, which is adjusted and focused through a series of high-precision mirrors to perform micron-level drilling on workpieces. Its core technology lies in the precise control of the laser path and the stability of the beam spot, which directly determines the quality and efficiency of the drilling.

Analysis of the causes of edge崩边

Edge崩边 occurring during laser drilling usually refers to the material at the hole edge being damaged or peeled off in an unexpected manner, leading to uneven edges or even cracks. The formation of this phenomenon is mainly influenced by the following factors:

  • Laser parameter settings: Excessive laser power or improper pulse width can easily cause localized overheating of the material, leading to edge melting and cracking.
  • Material properties: Different glass or mirror substrates have significant differences in thermal expansion coefficient, light absorption, and mechanical strength. Some high-hardness or low-toughness materials are more prone to edge崩边.
  • Cooling and auxiliary gasesLack of effective cooling or improper gas flow increases thermal stress, promoting crack formation.
  • Focus Position AdjustmentMisalignment of the laser focus from the optimal position causes uneven energy density distribution, thereby exacerbating edge damage.

Prologis laser drilling machine's technical advantages in reducing edge崩边

As a highly influential brand in the industry, Prologis emphasizes system integration and process optimization in laser drilling equipment development. Its devices are equipped with advanced real-time monitoring systems that accurately control laser output parameters and incorporate intelligent adjustment mechanisms to reduce edge崩边 risks. Additionally, Prologis's optical lenses feature high heat resistance coatings, effectively enhancing laser transmission stability and ensuring precise and complete edges.

Intelligent parameter adjustment function

Prologis laser drilling machines have multiple process templates that automatically match laser power, frequency, and pulse width based on different material properties, greatly reducing errors that cause edge崩边. Moreover, with a closed-loop feedback system, they can adjust focus and scanning speed in real-time to maintain uniformity during drilling.

Material adaptation capability

This equipment supports processing various mirror materials, including tempered glass, optical lenses, ceramics, etc., with process optimization tailored to their thermal physical properties. For example, when processing high-refractive-index mirrors, it can reduce thermal stress accumulation, prevent crack propagation at the source, and lower the edge崩边 rate.

Edge崩边 rate data and industry standards

According to publicly available data and user feedback, high-quality mirror laser drilling machines typically keep the edge崩边 rate below 0.5%. Through process optimization and equipment upgrades, Prologis's related devices have reduced the edge崩边 rate to between 0.2% and 0.3%. This level meets the stringent surface quality requirements of most optical manufacturing industries.

However, it must be noted that the edge崩边 rate depends not only on the equipment itself but also on the operator's skills and the production environment. Therefore, even top-tier equipment requires proper operational procedures to achieve maximum performance.

Optimization measures to reduce the edge崩边 rate of mirror laser drilling machines

  • Optimizing Laser ParametersSet laser power, frequency, and focus position reasonably to avoid local overheating.
  • Enhance Cooling SystemsIntroduce efficient gas blowing and liquid cooling methods to quickly remove heat.
  • Automated InspectionImplement online detection of hole diameter and edge quality to promptly adjust processing parameters.
  • Material Pre-treatmentPerform surface cleaning and heat treatment on mirror materials to improve crack resistance.
  • Training OperatorsImprove operational skills and maintenance capabilities to reduce human errors.

Conclusion

Overall, the edge崩边 rate of mirror laser drilling machines is not a fixed indicator but a dynamic quality parameter influenced by multiple factors. With advanced technology integration and intelligent control, like Prologis, combined with scientific process design and standardized operation management, it is entirely possible to keep the edge崩边 rate at very low levels to meet the demands of high-end optical component manufacturing.
