Reflective metals laser cutting – Carlos

Reflective metals laser cutting.  XT Laser cutting companies in practice often encounter high-reflective metals such as aluminum. The cutting of these metals requires special attention and the preparation of a laser cutter. Namely, due to the reflexive properties of such metals, careless cutting, or non-preparation of the sanding surface. May result in damage to the lens of the laser. In addition to aluminum, laser cutting of stainless steel that is further processed by polishing can also be a major problem.

Why are there any cutting difficulties?

Co2 laser cutting function on the principle of directing the laser beam. Through the mirrors and lenses on the small surface of the cutting material. Since the laser beam is actually a light beam of high strength, the reflexive properties of metal can cause laser beam rejection. In this case, the reversed laser beam enters through the head of the laser cutter  on the lenses and the mirror system, which can cause damage.

In order to prevent laser cutting potential rejection several actions requir. Reflective metal is cover with a layer or a device that absorbs the laser beam. This approach to cutting not affect the quality and the precision of the cut. The laser cutter is protect by destruction.

In addition to the above-mentioned processing, most modern laser cutting machines come with an implemented self-protection system.  The whole system works on the principle of radiation measurement, that is, its monitoring when cutting. However, the advancement of technology has developed laser cutters that are resistant to such occurrences, and these are fiber lasers.

Today, in addition to the laser cutters,  is also practiced when it comes to laser metal cutting the use of fiber laser. Fiber laser technology is one of the latest cutting techniques that gives significantly better performance than CO2 lasers.
