Working principle of UV laser cutting machine
UV laser cutting machine refers to high precision laser cutting machine that uses 355nm UV laser. It emits high density & high energy laser light on the material surface and realize cutting by destroying the molecular bond inside the material.
The structure of UV laser cutting machineUV laser cutting machine consists of UV laser, high speed scanner system, telecentric lens, beam expander, vision positioning system, electronic control system, power source components,
laser water chiller and many other components.
Processing technique of UV laser cutting machineWith focal round light spot and scanner system moving back and forth, the material surface is stripped layer by layer and finally the cutting job is done. The scanner system can reach up to 4000mm/s and the scanning speed times decide the efficiency of the UV laser cutting machine.
Pros and cons of UV laser cutting machineProns:
1.High precision with smallest focal light spot below 10um. Small cutting edge;
2.Small heat-affecting zone with low carbonation to the materials;
3.Can work on any shapes and easy to operate;
4.Smooth cutting edge with no burr;
5.High automation with superior flexibility;
6.No need for special holding fixture.
Cons:
1.Higher price than traditional mold processing technique;
2.Less efficient in batch production;
3.Applicable to only thin material
Applicable sectors for UV laser cutting machine
Due to the high flexibility, UV laser cutting machine is applicable in metal, non-metal and inorganic material processing, making it the ideal processing tool in sectors like scientific research, electronics, medical science, automobile and military.
As mentioned before, one of the components of UV laser cutting machine is laser water chiller and it serves to take away the heat from the UV laser. That is because substantial amount of heat generates during the operation of the UV laser and if those heat can not be removed in time, its long-term normal performance can not be guaranteed. And that’s why so many people like to add a laser water chiller to the UV laser cutting machine. S&A offers CWUL, CWUP, RMUP series recirculating laser chiller for UV laser ranging from 3W-30W with cooling stability of 0.1 and 0.2 for selection.
