Application and development of special machining technology in remanufacturing field

Special machining technology can accomplish many machining tasks which cannot be accomplished by traditional machining technology.In recent years, it has been more widely used in the field of remanufacturing.Remanufacturing refers to the reprocessing of waste parts to make up for defects and reuse.This technology is conducive to reducing manufacturing cost, shortening manufacturing cycle and saving resources.Firstly, the process flow of remanufacturing is introduced in this paper.Then, the characteristics of special processing technologies such as magnetic grinding technology, welding technology, thermal spraying technology and laser cladding technology and their applications in the field of remanufacturing are introduced, respectively.Finally, the development of remanufacturing technology is prospected.
