报道了对４５＃钢圆筒刻片开展的ＣＯ２激光刻槽工艺研究情况。采取了把工件浸入水中冷却的措施，克服了刻槽余热引起的烧伤现象，研究了圆筒外表面激光斜刻槽的工艺条件，并且给出了槽深度均匀性解剖检测的结果以及激光刻槽槽体的组织和性能分析 Reported on the 45 # steel cylinder engraved CO2 laser groove technology research. The work piece is immersed in water to cool it, overcame the burnt phenomenon caused by residual heat of the groove, the condition of the laser bevel groove on the outer surface of the cylinder was studied, and the result of the anatomical testing of the uniformity of the groove depth, Tissue and performance analysis of the tank
