Eccentric shaft sleeve

In fact, the failure of dies is due to the wear of local surface materials and other reasons, and the processing cycle of dies is very long and the processing cost is very high (especially the manufacturing and processing cost of precision complex dies or large dies is as high as hundreds of thousands or even millions of yuan).

Therefore, it is undoubtedly a method of great economic significance to strengthen the surface of the specific parts where the die manufacturers really bear the wear effect so as to greatly extend and improve the service life of the tools and dies.

In addition, most of the molds are invalid and scrapped only because a thin layer of material on the surface is worn. Therefore, it is only necessary to repair the worn local areas of the mold and key metal parts, and apply a layer of high hardness and high wear resistance metal layer on the surface of the mold that actually bears the wear during the repair process, which can "turn waste into treasure" and not only repair the mold, The service life of the repaired mold will also be greatly improved compared with the original mold, with huge economic benefits (for example, it only takes a few days to repair a large shaft of a power plant motor, including various preparation times, using the micro beam cold welding machine, but it can create economic benefits of millions of yuan).
