Description

Technical Field

[0002] Aluminum and aluminum alloys have the advantages of low density, low price and excellent machinability, and are important materials in the field of aerospace. In order to meet the requirements of aerospace, large-sized flat aluminum alloy sheets need to be processed by CNC into grids of different specifications (such as squares and triangles) before being applied to wall panels and boxes. However, the wear resistance and corrosion resistance of aluminum alloys themselves are relatively low, so the existing technology will modify the surface of aluminum alloys, such as using oxidation anodes, thermal spraying, electroplating, laser cladding and other processes to improve the wear resistance and corrosion resistance of the aluminum alloy surface. However, the products obtained by the current processing methods still cannot meet the actual needs of production, and cutting fluids are used in CNC processing projects. The cutting fluids will remain on the flat plates. If they are not cleaned in time, the surface of the plates will be corroded.

After one side of the flat plate is detected, the other side can be switched for detection, which effectively detects the surface of the flat plate to avoid residual liquid before the flat plate is sprayed, affecting the spraying effect.
