摘要：
The development situation of shield machine remanufacturing in China was expounded, and the development shortages and challenges were pointed out. The damage forms and the repair methods of key parts of shield machines, such as main bearing, cutter and cutter head, hydraulic system, reducer, screw conveyer were summarized. The potential and advantages of additive repairing technologies such as laser cladding, thermal spraying, cold spraying and cold welding in shield machine remanufacturing were analyzed. The future development trends of shield machine remanufacturing were finally provided. © 2021, China Mechanical Engineering Magazine Office. All right reserved.
