In fact, the repair process of wheel hub wire drawing is not complicated, which depends on a good wheel hub wire drawing machine. My brother joined Gubert in Chengdu to do wheel drawing, which is intelligently controlled. My brother learned it all after studying there for a few days. It was originally a zero foundation and had no experience at all. As for how to charge, it still depends on the market situation. He usually charges 5 10 in Chengdu, and the cost is very small, so I won't disclose it.
