Optical-fiber laser cutting machine is using optical-fiber laser generator as the laser cutting machine of light source.Wherein cutting head conduct
The important component of laser processing comprising the cutting head of ontology and cutting head bottom, laser beam pass through laser cutting head sheet
The cleaved mouth in internal space projects, and is processed to cutting workpiece.The optical mirror slip being wherein equipped in ontology, since laser shines
It penetrates on mirror lens and condenser lens, even if mirror lens only absorbs the small part energy of laser with condenser lens, but by
Power density entrained by laser is very big, causes the heating of cutting head excessively high, even if cannot distribute, to make ontology with
And the possibility of the precision parts damage such as the eyeglass of installation on the body increases, and shortens the working life, increases the maintenance of lathe
Cost.
