How Precision Laser Cutting Works

Precision laser cutting is a technique that uses thermal energy to separate sheet metal parts. Laser cutting is an innovative non-contact process, where high-quality materials are cut using a laser directed through nozzles. This procedure is entirely accurate; the laser beam is guided by a mirror or fiber towards the machine’s cutting head, concentrating on a point on the surface of the working material and raising its temperature until it melts or vaporizes. Once the laser beam has passed through the body, the cutting process begins, redirecting the laser beam at the points determined according to the selected geometry until the material is wholly separated, generating exact cuts.

There are CO2 or fiber lasers, and the applications of precision laser cutting vary depending on the type of laser used and the material being cut, such as steel, stainless steel, plastic sheets, wood, aluminum, and cardboard; they also vary by the thickness of the sheets to be cut, which can range from 0.5 to 30mm and because they are so thin they do not deform.

Once the cutting process has been completed, which is carried out using specialized and highly technological machinery, pressurized gas (oxygen, nitrogen, or CO2) is used to extract the resulting material.

Among the main reasons for using laser technology in the process of cutting sheet metal parts in the industrial sector are

High precision allows us to make cuts of different geometric shapes, whether irregular, thin, or with complex contours. It is suitable for pre-cutting or cutting off excess material.

Versatility: it can be used to separate different organic and inorganic materials, including metal sheets or materials that allow the construction of pieces with different geometries made of steel, stainless steel, or aluminum sheets.

Agility: the laser cutting process does not require cutting dies for the manufacture of parts and allows for silhouette adjustments.

Efficiency: After using the laser, it is unnecessary to carry out further processing of the part, such as sealing or sanding, which saves time in the manufacturing process.

Depending on the machinery used and the part’s material, it can be subjected to different processes such as cutting, engraving, marking, etc.

Laser technology allows us to process a multitude of plastic, textile, organic or metallic materials.

Precision laser cutting allows processing sheet metal parts and metallic materials such as:

  • Steel sheets
  • Stainless steel
  • Aluminum
  • Anodized aluminum
  • Chrome
  • Precious Metals
  • Painted metal
  • Brass
  • Copper
  • Titanium

The applications of precision laser cutting are infinite thanks to its excellent versatility, where it can be applied to cutting in the metal industry for high precision cuts, in the textile industry for cutting patterns, models, and molds; in architectural models, where details are taken care of, for the manufacture of chassis, engine parts or automotive information. Also, laser cuts are made on mugs, keys, motherboards, glass, acrylic, vinyl, rubber, fabric, and even leather.
