采用智能成套激光清洗装备对回厂再制造的精轧机接轴长轴进行激光清洗，去除表面氧化皮。   该智能成套激光清洗装备集成千瓦级激光器和六轴机器人，实现了清洗路径的主动柔性控制，千瓦级激光器利用矩形平顶光斑代替圆形高斯分布光斑对长轴表面金属氧化层进行清洗，解决了高斯分布光斑能量分布不均匀问题，光斑重叠小，清洗效率高，清洗质量达到Sa3级。

The intelligent complete set of laser cleaning equipment is used to clean the long shaft of the drum-tooth gear coupling of the finishing mill remanufactured in the factory to remove the surface oxide. The intelligent complete set of laser cleaning equipment integrates kilowatt laser and six axis robot, realizes the cleaning path active flexible control, with kilowatt laser using rectangular flat top spot instead of circular Gaussian distribution spot of long axis surface oxide which solves the problem of Gaussian distribution spot energy distribution, the spot overlap is small, the cleaning efficiency is high , and the cleaning quality is up to Sa 3 level.
