What is laser cutting?

Laser cutting is an innovative and highly effective technology for cutting and machining different types of materials. Thanks to this technology we can produce high quality products for a short period of time.

The term „laser” in fact is an acronym for “Lіght Аmрlіfісаtіоn Ѕtіmulаtеd Еmіѕѕіоn Rаdіаtіоn”.

This term by itself is used to explain that the technology of laser cutting uses a light beam with a certain level of power for cutting and engraving different types of materials.


What is laser cutting?

The lasers designed for metal machining use a special method for thermal cutting. This method includes a high amount of light energy focused on a single small spot with a diameter of several microns.

The laser beam’s energy is directed on the exact spot where needed which guarantees high accuracy and precision during the cutting and engraving process. The moment when the laser is cutting an element oxygen, nitrogen, carbon dioxide, or other type of gas blows the excess material away from the work zone.

In this way the material that is being machined won’t need finishing touches.

Main operation method of a laser machine

The laser cutting’s mechanism isn’t too complex and it includes the following steps:

Main methods of laser cutting

Sublimation cutting

During this method the laser heats the metal to the point when it evaporates (sublimation). Inactive and inert cutting gas such as nitrogen removes the melted metal from the work zone. This laser cutting method is used most often for machining thin metal sheets.

Cutting with oxygen

The main difference between this method and the previous one is that the material is heated only until the point of combustion. The oxygen is used as a cutting gas, the material enkindles and it forms oxides that melt because of the excess energy resulting from the combustion process. After that the oxygen flow removes the slag from the work zone. This cutting method is used for machining low carbon steel.

Cutting with melting

During the melting method the material is melted directly from the laser beam. To remove the melted metal from the work zone inert gas is used (most often this is nitrogen). This method is also applied for cutting steel alloy (stainless steel).

Advantages of laser cutting

Laser cutting is widely used in metal machining to produce elements with a different shape and size. That’s because it allows very precise and highly effective cutting of complex elements from steel and sheet iron.

Those parts that are laser-cutted are high-quality and don’t need further machining. The amount of metal swarf produced during laser cutting is minimal. The reason for this is that the laser beam has millimeter-precise focus on the work spot.

This metal cutting method lacks mechanical stress on the material that is being processed which offers protection against different defects. Thanks to its high precisionlaser cutting can be used for machining both fine and hard materials.

The machines used for laser cutting offer high efficiency, precision and offer a fully automated process. Laser equipment can be used in those production spheres where conventional equipment is no longer applicable.

Disadvantages

The prices of laser cutting equipment are a little bit higher than the prices of conventional laser cutting equipment.Butthe initial investment in laser cutting machines has a high return given the many advantages those machines offer.

Materials that reflect light such as glass aren’t suitable for laser cutting. The gauge limit for the machined material is no more than 20 millimeters.

Laser cutting price

The price is set on the basis of the material’s gauge, type, size and the size and number of the elements. For example, if we need to cut a large number of small elements, this will take much time and consequently the service price will increase.

Spheres where laser cutting is applied

The advantages of laser cutting allows us to apply this method in many metal production spheres. The high precision and quality of the final products is helpful when it comes to making products that require a very precise manufacturing process.

Laser cutting has a wide application in the metal cutting industry for cutting different types of metal, sheet iron and steel with a gauge of 20 mm.

Laser cutting is also used in the aviation industry, engineering, medicine, production of engraving instruments and also for machining some types of plastic materials.

The advantages of this method allow it to be used in the production of shaped iron with a different complexity of the shape. Besides the spheres we have mentioned above, laser cutting is also successfully applied in plywood, plexiglass and polystyrene machining as well as the machining of other materials.

The number of spheres where laser cutting can be used grows each year. And this metal cutting method is gradually turning into one of the most preferred and used ways for a quick and precise cutting and engraving of different materials with minimal waste.
