特种加工技术在再制造领域中的应用与发展

特种加工技术能完成许多传统加工技术无法完成的加工任务，近年来越来越多地被应用于再制造领域。再制造是指对废旧的零部件进行再加工，以达到弥补缺陷、再次使用的目的，该技术有利于降低制造成本、缩短制造周期、节约资源。本文首先对再制造的工艺流程进行简介，再分别介绍磁力研磨技术、焊接技术、热喷涂技术、激光熔覆技术等特种加工技术的特点及其在再制造领域的应用，最后对再制造技术的发展进行初步展望。 

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.
