As a result, some factors affecting the quality of laser drilling what.
In order to obtain higher quality of hole, so you should according to the general principles and characteristics of laser drilling, affecting the quality of drilling parameters is analyzed with understanding.
These parameters are generally include: laser pulse energy, pulse width, from coke deposition, laser pulse repetition frequency, the properties of materials.
and the size of the laser cutting machine in punch punch and precision is difficult to control, can laser equipment factory in guangzhou to share below four points need to master control, specific as follows:
first, aperture size control
laser cutting machine use small divergence Angle of laser ( 0. 001-0. 003rad) And shorten the focal length or reduce the output energy can make pore size smaller. For high melting point. Good thermal conductivity material aperture 0 can be realized. 01 ~ 1 mm small hole machining, the smallest aperture can reach 0. 001mm.
in the second place, the depth of the hole control
increase 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.
third, improve the laser machining hole roundness
processing, laser mode USES the base model focusing lens with aplanatic lens, lens and optical 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.
4, lower punch taper
usually taper hole increases with the aperture ratio increased, with the appropriate laser output energy or small light for many times, the shorter the focal length, the small lens refractive index and decreases the Angle between the incident ray and the axis measures can reduce hole taper.
