Our IQFPS wheel hub bearing forgings are the same as the world-renowned bearing companies, which use Jiangyin Xingcheng 55# special steel. The national standard is GB/T699-2015.Quality needs to be controlled from the source. In addition to appearance problems, forgings often have black skin, sand holes and other incoming problems that need to be found after turning, which not only wastes tools, affects work efficiency, but also increases the defect rate. Up to now, Xingcheng's forgings have not found any problems in the incoming inspection. The rough surface of the forgings is flat, the size is within the range required by the drawings, and no rust and bumps are found on the appearance. Good forgings can improve the utilization rate of tools and drills. The processing difficulty is reduced and the output is increased.
