Laser engraving

Laser skills are generally carried out in the manufacturing field for a particular manufacturing process. The laser machine emits photons and works according to the principle of optical amplification. The purpose of this ability extends to marking, cutting, stamping and engraving objects.

The method of marking or engraving an object with a laser beam is known as laser marking or laser engraving. The main difference between this ability and other people is that this method does not use inks or maintain contact with the recorded object. The laser marking system consists mainly of 3 areas, which consist of a laser, a controller and a contact area. With the help of the laser beam, preferred patterns are formed on the surface of the target object together with the control. A controller usually charges a computer and regulates the depth, speed and trajectory of the beam. There are mainly three types of laser marking systems. The main group of machines is an X-Y table, in which the laser system opens in the X-Y direction and remains in the stationary position in addition to the surface. In some cases, the laser system remains stable in addition to the amount of work that moves along the X-Y directions. This type also contains the position in which the laser adopts the X direction and hits the working section in the Y direction area. The following group of structures is mainly for cylindrical connecting surfaces. At this point, the laser beams move helically and create the impact on the contact surface. The last group uses galvo mirrors and controls the movement of the laser beam through the work area. This is the best way to shape the preferred shape, and the unnecessary surface evaporates with this capacity. Several operations are involved in this engraving technique.

Ablation: at this point, the outermost layer is evaporated using the process. This does not change the inner layer of the surface. The process goes well with surfaces covered with paint or anodized.

Annealing: When using the annealing technique, a contrast mark is formed on the metal surface. Usually heats the surface by making the desired carving on the metal. The process temperature is adjusted according to the property of the metal that is intended to achieve the desired effect.

Bleaching: this method is usually carried out on plastic surfaces, the quality of the effect depends on the wavelength of the laser beam. Typically, the colors of the material change by absorption of the laser beam that passes through the interface. The jet completely changes the color pigments without damaging the connection surface.

Foam: in this process, the area where the procedure is performed is lifted from the normal surface. When the laser is connected on the surface, it melts and collects the gas bubbles, forming a bump on the surface.

Computer-controlled laser systems are the superior and flexible use in the development industry. It uses the engraving of the most complex materials and is generally used in metals, plastics, stones, glasses and even jewelry.
