Its excellent corrosion resistance can maintain a brand-new appearance under various harsh climate conditions; the characteristics of light weight and high strength not only reduce the burden on the building structure but also improve the overall safety; in addition, with good processing performance and diverse surface treatment properties, aluminum veneer can easily integrate into various design styles and meet the wide range of needs from commercial complexes to high-end residences. However, in the processing chain of aluminum veneer from raw material to the final decoration, the hole-opening link plays a crucial role. The precise layout and high-quality processing of holes are not only related to the installation convenience and structural stability of the aluminum veneer but also directly affect the aesthetic degree of the overall decoration effect. Therefore, the accuracy and efficiency of hole-opening have become important indicators for measuring the technical level of aluminum veneer processing and have a profound impact on the quality and production cost of the final product.

[0003] However, the existing aluminum veneer hole-opening devices have problems of insecure and inaccurate fixation of aluminum veneer, which in turn affect the product quality.
