The frame fan assembly of aluminum alloy doors and windows is generally connected by screws, so whether it is the assembly of horizontal and vertical bars or the fixing of accessories, it is necessary to drill holes in the corresponding positions. For profile drilling, small bench drills or **** drills can be used. Because the former has a table, it can effectively ensure the accuracy of the drilling position; the latter is because of the ease of operation. Before drilling, according to the requirements of the assembly, the wire should be positioned on the section. The location of the drill hole must be accurate and the hole diameter should be suitable. The drilling must not be changed repeatedly on the surface of the section. Once the hole is formed, it is difficult to repair.
