Can ultra-thin metal materials be cut with a metal laser cutting machine? No!

Ultra-thin metal generally refers to metal materials with a thickness of less than 0.2mm, which are usually used in micro-precision fields, such as copper foil, molybdenum foil, stainless steel, alloy, etc.

Previously, a customer of Laisai Laser found a large metal laser cutting machine manufacturer when looking for ultra-thin metal copper foil cutting, but he couldn't do it. At this time, the laser cutting machine manufacturer suggested that the customer use a low-power fiber laser, but the effect was not ideal. The disadvantage is that infrared light will deform the material when cutting ultra-thin metal materials, the heat effect is too large, the edge is severely carbonized, there are burrs on the edge, the cutting gap is large, and the precision is low.

Therefore, the customer found another precision laser cutting manufacturer, which used the MOPA vibration mirror mode, but the effect was the same as before and could not meet the requirements. At this time, the manufacturer recommended the use of an ultraviolet marking machine, which has better effect than the infrared fiber vibration mirror, but has low efficiency, but the edge is deformed and carbonized.

At this time, the customer would think, this kind of ultra-thin metal copper foil, stainless steel laser can't do, so can find other processing methods? However, the last manufacturer's UV laser marking machine obviously saw hope, so the customer began to collect information about UV laser cutting machines, understand Laisei laser and UV laser cutting machines, and see if it can meet the processing requirements. After detailed communication, Laisai Laser provided customers with past processing effect display and effect customers, saying that we can process this ultra-thin metal copper foil material. The customer was very happy and came to the company to perfectly solve the processing requirements. The customer said that this time he finally found a suitable manufacturer.

Then why are both UV laser marking machines and UV laser cutting machines UV lasers, and marking machines can't do it? Advantages of UV laser cutting machine:

1. It uses 355nm UV light source, which belongs to cold processing. Unlike fiber light source, UV laser cutting machine destroys the molecular bonds of materials, has little thermal impact, and is almost carbonized.

2.Compared with UV marking machine, UV laser cutting machine adopts telecentric lens, which has high power, small focus point and good processing efficiency.

3.Adopting camera positioning and vacuum adsorption, the cutting accuracy is high and there is no deformation effect on the product.

4.Adopting linear motor, it can process large fabrics and has high splicing accuracy.
