    影響激光切割表面質量的因素有哪些?

      1、激光應有高的光束質量,激光切割是基于熱效應的加工,為得到高的功率密度和精細切口,聚焦光斑直徑要??;
      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、對于汽化切割,所需功率最大,熔化切割次之,反應熔化切割則最小。
      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時所需功率由材料的性質和切割機理決定,切割反射率高、導熱性好及熔點高的材料,需較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.
      同時,為保證沿不同方向切割時的質量的一致性,激光束應有良好的繞光軸旋轉對稱性和圓偏振性以及高的發射方向穩定性,以保證聚焦光斑位置穩定不變。
      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
