The machining experiment of ultra fast laser engraving spiral grooves was discussed in the manufacturing of dynamic compressed air floating bearings.By reasonably planning the beam path and filling trajectory,as well as selecting and optimizing process parameters such as laser power,repetition frequency,scanning speed,and filling spacing,the ultra fast laser precision machining of spiral grooves in boron carbide ceramic dynamic compressed air floating bearing parts was achieved.The depth dimension accuracy and surface roughness of the spiral grooves meet the design technical requirements.The cross-sectional shape of the processed groove was better,and its processing efficiency was increased by 4 times.
