Picosecond laser glass cutting uv laser drilling

The cutting advantages of picosecond laser glass cutting machine are as follows:


1. High cutting accuracy: the positioning accuracy of the laser cutting machine is 0.003mm, and the repeat positioning accuracy is 0.002mm.


2. The slit of the laser cutting machine is narrow: the laser beam is focused into a small spot, so that the focal point reaches a high power density, and the material is quickly heated to the degree of gasification, which evaporates to form holes. With the relative linear movement of the beam and the material, the holes are continuously formed into narrow slits, and the slit width is generally 0.003-0.005mm.


3. The cutting surface of the laser cutting machine is smooth: there is no burr on the cutting surface, and the minimum edge chipping of the incision surface can be controlled within 0.01mm.


4. The speed of the laser cutting machine is fast: the linear cutting speed can reach up to 500mm/s, and the corner cutting speed can reach up to 300mm/s, which is much faster than the wire cutting speed.



5. The cutting quality of the laser cutting machine is good: non-contact cutting, the cutting edge is less affected by heat, there is basically no thermal deformation of the workpiece, and the collapse of the edge formed when the material is punched and sheared is completely avoided, and the cutting seam generally does not require secondary processing.


6. No damage to the workpiece: The laser cutting head will not contact the surface of the material to ensure that the workpiece will not be scratched.


7. Not affected by the shape of the workpiece: the laser processing has good flexibility, can process any graphics, and can cut pipes and other special-shaped materials.


8. Save mold investment: laser processing does not require molds, no mold consumption, no need to repair molds, save time for mold replacement, save processing costs, and reduce production costs, especially for the processing of large products.

2. Main features:


1. Picosecond laser has high electro-optical conversion efficiency, and the conversion efficiency is over 30%, which can greatly save power consumption during work, save operating costs, and achieve the highest production efficiency.


2. The picosecond laser only needs electric power to operate, no additional gas is needed to generate the laser, and it has the lowest operation and maintenance cost.


3. The output wavelength of the picosecond laser is 1.064 microns, which is 1/10 of the wavelength of CO2. The output beam has good quality and high power density, which is very conducive to the absorption of metal materials, and has excellent cutting and welding capabilities. The processing cost is the lowest.


4. The cutting head contains protective lenses, so that the consumption of valuable consumables such as focusing lenses is extremely small.


5. The thickness of cutting glass can reach 10mm.
