Fiber Laser Metal cutting machine

Laser metal cutting machine are designed for processing metal materials. With laser metal cutter you can perform both cutting and engraving or even welding. Such equipment provides a high-quality result of work with maximum productivity.

What metal is suitable?

A large number of metals are suitable for laser processing. However, it is important to pay attention to the thermal conductivity of the material. The lower it is, the more suitable it is considered.

For example, such materials as are suitable for cutting and perforation:

  • stainless steel (up to 12 mm.);

  • aluminum (up to 20 mm.);

  • brass (up to 12 mm.);

  • copper (up to 15 mm.);

  • steel (up to 30 mm.).

The machines also perform high-quality engraving and marking on precious metal.

For laser cutting, it is important that the material thickness starts at 0.2 mm.

What can be made on a metal cutter?

The types of products made on a laser machine for metal differ depending on the processing method. For example, using an engraving and marking machine, you can produce:

  • jewelry;

  • tokens and coins;

  • souvenir products;

  • numbers and plates;

  • promotional items and more.

Also, the equipment is capable of applying barcodes and QR codes.

If the machine is used for cutting, welding or punching, then it is possible to produce:

  • metal doors;

  • elevators;

  • parts for electronics, cars, ships and aircraft and more.

Laser metal cutters do an excellent job of cutting pipes, and on some models you can do welding work.

The scope of such equipment is very extensive. With it, you can make metal products of any complexity.

How the machine works

Laser metal cutters perform non-contact material processing using a high temperature beam. 

According to the type of working environment, machine tools for metal are divided into three types:

  • solid state (fiber optic);

  • gas;

  • gas dynamic.

Let us consider in more detail the principle of operation of solid-state machines.

The process of laser beam formation takes place inside the cable. It consists of:

  • thin semiconductor filaments of quartz;

  • doped cores (most often ytterbium);

  • diode bulbs.

When the machine is started, the bulbs light up and transmit light to the fiber, which in turn is saturated and activates the core. 

The formed beam is projected onto the material, passing through the optical lens. Due to the high temperature and high speed of the laser beam, the material begins to heat up quickly and evaporate. Thus, metal processing is performed.

CNC metal cutters operate with the help of a control system and installed programs. The programs contain the coordinates of the movement of the machine head and the necessary settings. And the control system controls the movement of the beam in accordance with the program.

Cutting features

Some materials have their own nuances that should be taken into account when laser processing. Here are some of them:

  • Aluminum. The material has a high thermal conductivity and at the same time weakly absorbs the beam. For this reason, the metal needs settings with increased power and reduced processing speed.

  • Brass. Due to its two-component nature (zinc and copper), the material has a high melting point (practically 1000 ° C). In addition, the metal has a high hardness and poorly absorbs the laser beam. Therefore, it is recommended to use solid state (fiber optic) equipment for working with brass.

Please note that metals with high reflective properties and increased strength are not suitable for laser processing. For example, tungsten, polished brass and anodized aluminum.

Conclusions

Laser metal cutters are versatile equipment that can replace the use of a large number of tools and labor. Machines not only cope with the processing of various types of metals, but also perform many complex tasks at the highest level. In addition, lasers have a wide application profile and are also available in a wide range. Therefore, this equipment is suitable for both small enterprises and serious mass production.
