Factory direct supply, reasonable prices, quality assurance aluminum welding aluminum knee protection measures 1, before welding chemical + mechanically remove the oxide portion of the workpiece and the surrounding groove and the wire surface, the order is the first chemical cleaning CNC precision machining, after mechanical polishing; 2, the welding process to be used to protect a qualified protective gas; 3, when welding aluminum luggage rack factory, using flux, constantly used during welding wire prick pool surface oxide film. Aluminum alloy shell recommend using one of the following three tools: not ultrafine particles carbide coating with aluminum-containing carbide coating not (PVD) method, such as plating TiN, TiC and other tools with diamond cutter capacity crumbs space should be large processing, is generally recommended to use two teeth, the rake angle, clearance angle should be large (e.g. 12 ° -14 °, inclusive tooth posterior horn). If only the general face milling, you can use the main angle of 45 ° indexable face mills, equipped with specially machined aluminum blade, should be better results. Common aluminum sheet thickness: Advanced Metal Roofing (and walls) systems typically 0.8-1.2mm (generally traditional ≥2.5mm) computer stand machining | machining | aluminum products from Dongguan Cavey Cavey aluminum products is limited.
