4000W Fiber laser cutting machine equipment as a new tool is more and more mature used in a variety of industries, including fiber laser cutting machine,
laser engraving machine, laser marking machine, laser welding machine, etc.. So how is the use of laser cutting, how to distinguish the quality of laser cutting?
First of the laser energy in the form of light is concentrated into a high density of beam, the beam to the work surface, produce enough heat,
melt materials, coupled with high pressure gas with beam coaxial direct removal of molten metal, so as to achieve the purpose of cutting,
it shows that laser cutting processing has essential difference with the mechanical processing machine tool.
It is the use of the laser beam is emitted from the laser generator, the light path system, focusing on a high power density laser beam irradiation condition, laser heat absorbed by the workpiece material, workpiece temperature rise sharply, arrived at the boiling point, material vaporization and the beginning of the formation of holes, accompanied by high pressure air flow, with the movement of the relative position between the beam and workpiece, eventually to form material cutting seam. The process parameters (cutting speed, laser power, fiber laser cutting machine price, gas pressure, etc.) and the movement trajectory are controlled by the NUMERICAL control system, and the slag at the slit is blown off by the auxiliary gas of a certain pressure.
Generally speaking, laser cutting quality can be measured by the following 6 standards.
1. Cutting surface roughness Rz
2. Notch hanging slag size
3. Trimming perpendicularity and slope U
4. Cut edge fillet size R
5. Stripe drag n
6. flatness F
