镜板是水轮发电机组推力轴承的心脏部件，它的质量直接关系着水轮发电机组的安全运行。三峡水电站ALSTOM发电机组镜板材料采用45号锻钢制作而成，由于对其粗糙度、光洁度、表面硬度和波浪度都有非常严格的技术要求，在发电机组的A修过程中，需要对发电机组推力轴承的镜板表面实施研磨和抛光处理。得益于新型镜板研磨机在该机组中的应用，其工作效率和镜板研磨的精度得到了显著提高。介绍了新型镜板研磨机的工作原理及应用效果。
鏡闆是水輪髮電機組推力軸承的心髒部件，它的質量直接關繫著水輪髮電機組的安全運行。三峽水電站ALSTOM髮電機組鏡闆材料採用45號鍛鋼製作而成，由于對其粗糙度、光潔度、錶麵硬度和波浪度都有非常嚴格的技術要求，在髮電機組的A脩過程中，需要對髮電機組推力軸承的鏡闆錶麵實施研磨和拋光處理。得益于新型鏡闆研磨機在該機組中的應用，其工作效率和鏡闆研磨的精度得到瞭顯著提高。介紹瞭新型鏡闆研磨機的工作原理及應用效果。

The mirror plate is a critical part of thrust bearing of hydro generators and its quality is directly related to the safe operation of the generator. The material of the mirror plate of ALSTOM generator of Three Gorges Project is made of No. 45 forged steel. Due to the strict requirement of roughness, fineness, surface hardness and waviness, in A overhaul of generator, the grinding and polishing treatment to the mirror plate surface of the thrust are required. Due to the application of the new grinder in ALSTOM generator of Three Gorges Project, the work efficiency and the grinding accuracy of mirror plate are significantly im-proved. The working principle and application effects are introduced.
