  • 激光切割的切割质量好坏?
  • 本站编辑:杭州创莘金属制品有限公司发布日期:2019-04-08 12:29 浏览次数:

1 切缝垂直度

要求垂直度好,切缝表面光洁,无条纹。

2 切割缝口宽度

切口宽度与光束模式和聚焦后的光斑直径有很大的关系,根据光束模式和焦距,二氧化碳激光束聚焦后的光斑直径一般为0.12-0.3mm。

3 热影响区宽度

热影响区尽可能小,没有材料燃烧,没有熔化层形成,没有较多的熔渣,没有脆性断裂。

切口表面粗糙度。 他是衡量激光切割表面质量的关键。厚度小的工件比厚度大的工件容易得到较高等级的粗糙度。切割金属的同一切口表面上,中,下部分的粗糙度并不相同,靠近激光束上端表面的粗糙度最小,越往下端的粗糙度越大。对较薄工件而言,如厚度小于3mm,激光切割表面的上,中,下部分的粗糙度差别很小。激光切割表面质量等级一般以下端粗糙度为标准。这样较切合实际,也易于掌握。

Require a good degree of vertical, cut surface smooth, no stripes.
2 slit width
The width of the incision has a great relationship with the beam mode and the diameter of the focused spot. According to the beam mode and focal length, the diameter of the light spot after the focus of the carbon dioxide laser beam is generally 0.12-0 .3 mm.
3 Thermal impact area width
The thermal impact area is as small as possible, no material combustion, no melting layer formation, no more slag, no brittle fracture.
Surface roughness of the incision. He is the key to measuring the quality of laser cutting surfaces. The workpiece with a small thickness is easier to obtain a higher degree of roughness than the workpiece with a large thickness. The roughness of the cut metal on the surface of the same mouth, middle and lower parts is not the same, and the roughness near the surface of the upper end of the laser beam is minimal, and the roughness of the lower end is greater. For thinner workpieces, if the thickness is less than 3mm, the roughness of the upper, middle, and lower parts of the laser cutting surface is very small. The quality grade of laser cutting surface is generally the standard for the bottom roughness. This is more practical and easy to master.
