How to test aluminum profile processing technology

Finished aluminum frame products refer to products like clean rooms, workbenches, assembly line brackets, industrial fences, etc., assembled and customized with aluminum alloy profiles. The aluminum profile processing technology refers to the technology of punching and cutting aluminum profiles. How to check the aluminum profile processing technology from these finished frame products?　　 We use the workbench as an example. When the workbench is made of aluminum profiles, it must be connected with some aluminum accessories. We disassemble the aluminum fittings of a workbench, check whether the cut in the joint is flat, check whether the hole type and thread match, whether there is too large a hole; then check whether the cutting angle of the aluminum profile is accurate, and the length of the cut Whether it is within the error range.　　 Through these, we can very well check whether the aluminum profile processing technology is qualified or unqualified, whether it is good or not. If the aluminum processing technology is not good, it will cause the end face of the aluminum profile to be uneven, or the drilled threaded hole is too large or too small, the depth is incorrect, etc., it may also be that the cutting accuracy is not enough, resulting in the incorrect length of the aluminum profile, increasing Installation is difficult or cannot be installed.
