The choice of the laser laser cutting machine configuration

Laser cutting machine equipment according to user configuration by the laser processing performance, processing materials, shape, size and selection of different laser, available for selection of laser respectively shaft fast flow co2 laser, radio frequency (rf) board debugging laser, laser, solid laser and fiber laser, etc. 1, improve the laser machining hole roundness laser mode USES the base mould processing, focusing lens with aplanatic lens, and the lens axis and the laser beam axis coincidence, artifacts for deviating from the focal point and select the appropriate laser energy can improve the processing and roundness. 2, reduce drilling taper hole taper usually increases with the aperture ratio increased, with the appropriate laser output energy or small light for many times, shorter focal length, small lens refractive index and decreases the Angle between the incident ray and the axis measures can reduce hole taper. 3, small aperture control adopts the divergence Angle of laser ( 0. 001-0. 003rad） And shorten the focal length or reduce the output energy small aperture can be obtained. For high melting point. Good thermal conductivity material aperture 0 can be realized. 01 ~ 1 mm small hole machining, small aperture can reach 0. 001mm。 4, the depth of the hole control improve the laser output energy, adopt reasonable pulse width ( Materials and thermal conductivity, the better, the pulse width of the shorter the YiQu) Model, the application base model ( Light intensity is a gaussian distribution of single mode) Big hole depth can be obtained. For the size of small deep Kong Yi by laser irradiation for many times, with short focal length ( 15～30mm） The objective of punch. Laser cutting machine, in the process of cutting, only cutting head along the X, Y direction, workbench fixed position.
