  影响济南激光切割表面质量的因素有哪些?   What are the factors that affect the surface quality of laser cutting in Ji'nan?   1、激光应有高的光束质量,激光切割是基于热效应的加工,为得到高的功率密度和精细切口,聚焦光斑直径要小;   1, laser should have high beam quality, laser cutting is based on thermal effect processing, in order to obtain high power density and fine incision, focus spot diameter is small;   2、对于汽化切割,所需功率大,熔化切割次之,反应熔化切割则小。   2. For vaporization cutting, the power required is the maximum, followed by melting, cutting, reaction, melting, and cutting.   3、切割用激光激光切割时所需功率由材料的性质和切割机理决定,切割反射率高、导热性好及熔点高的材料,需较大的激光功率和功率密度。   3, cutting laser laser cutting power required by the nature of the material and cutting mechanism, cutting high reflectivity, good thermal conductivity and high melting point of the material, the need for greater laser power and power density.   同时,为保证沿不同方向切割时的质量的一致性,激光束应有良好的绕光轴旋转对称性和圆偏振性以及高的发射方向稳定性,以保证聚焦光斑位置稳定不变。   At the same time, to ensure the consistency of quality cutting along different directions when the laser beam should have good rotated around the optical axis symmetry and circular polarization and direction of high stability, to ensure that the focal position is stable..
