Friction and abrasion of aluminum alloy wheels is a common problem, which is relatively simple to deal with:
1. First, it needs to be polished, and then it needs to be filled with special filling and repairing materials for aluminum alloy wheels (remember not to use sheet metal ash and putty ash). After the wheels need to be sprayed with special high-temperature primer, the corresponding color paint needs to be sprayed, and finally the special high-temperature bright paint for the wheels needs to be sprayed;
2. When the wheel hub is deformed and cracked, it needs professional wheel shaping and aluminum alloy welding technology, and after welding, it is necessary to ensure that there is no trachoma;
3. When the wire wheel is damaged, it is necessary to use the hub wire drawing machine. Hub tapping machine is divided into semi-automatic tapping machine and automatic tapping machine.
