Reflective metal laser cutting

We should pay more attention.When cut high reflective metal by laser.Cause it is very easy to damage the lens system. For this reason,we have developed special systems and techniques .So don’t reduce the cutting precision . So which are these techniques?

Reflective metals laser cutting

Laser cutting companies 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 reflective properties of such metals. careless cutting. or non-preparation of the sanding surface.They may result in damage to the lens of the laser. In addition to aluminum, laser cutting of some stainless steel  is also a major problem.Such as polishing stainless steel.

Why are there any cutting difficulties?

CO2 laser cutter,it direct the laser beam.Through the mirrors and lenses.On the small surface of cutting material.

Since the laser beam is actually a light beam of high strength.the reflective 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 potential rejection of the laser beam.it requires several actions.

Reflective metal must with a layer or a device that absorbs the laser beam. This approach to cutting doesn’t affect the quality and the precision of the cut.and the laser cutter  protected from destruction.

In addition to the above-mentioned processing, most modern laser cutting machines come with an implemented self-protection system.in the case of a laser beam reflection. This system  shuts down the laser cutter.And thus prevents the lens from destroyed. 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.

Cutting–fiber?CO2?Water jet?

Fiber laser cutter and CO2

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

Fiber lasers use optic fibers that guide the laser beam.instead of using a complicated mirror system. This type of laser is the fastest. and most cost-effective alternative .Compared to the CO2 reflective metals laser cutting.

Water jet cutting

In addition to the fiber laser cutter.we use another technique for reflective metals.It  is water jet cutting. The main reason for this is the fact. that fiber lasers lose their efficiency at a metal thickness larger than 5 millimeters.
