Aluminum alloy curtain wall processing preparation and accuracy requirements
Aug 17, 2018

In the preparation work for the processing of aluminum alloy curtain wall, the suitable processing location should be determined first, and the processing equipment and machine tools should be arranged according to the production and processing flow. The second is to carefully proofread the construction drawing, and re-test the building, and adjust the size of the aluminum alloy curtain wall processing profile according to the actual size. The next step is to calibrate the processing equipment and implements to ensure the processing accuracy requirements, and to check regularly.

 

In this process, you also need to check the corresponding certificates and materials. At the same time, it is necessary to ensure that the oxide film on the surface of the aluminum profile is intact and free from damage. Except for the aluminum material with excessive marks and large area scratches and distortion and bending deformation, it should be corrected first and then replaced. So, what are the accuracy requirements for aluminum alloy curtain wall processing?

 

The main precision requirements for aluminum alloy curtain wall processing include:

1. Allowable deviation of cutting size;

2. There should be no obvious processing deformation at the end of the cutting material;

3. The allowable deviation of the hole position is ±0.5mm, the allowable deviation of the hole distance is ±0.5mm, and the cumulative deviation is not more than ±1.0mm;

4. The through holes for rivets shall comply with relevant regulations and standards. Moreover, the aluminum profile should be assembled firmly, and the joint gaps should be reliably sealed.
