All the Advantages of Laser Engraving
The field of precision mechanics is vast and constantly evolving, closely linked to innovation and all those high-tech processes capable of continuously raising the level of detail definition. Within this inherently dynamic environment, laser engraving technology has carved out a leading role—thanks to the many advantages it offers—even though its presence in the industrial landscape is relatively recent. The reason is clear: laser engravers make it possible to carry out extremely precise machining operations. These are tools that guarantee both speed and cleanliness: no additional finishing steps are required.
The Laser: A Technique That Ensures Precision and Clean Cuts
A laser is a light beam in which the waves are aligned in the same direction and share the same wavelength. Thanks to this method, it is possible to achieve extremely fine surface cuts. The laser beam is directed onto the material to be processed via computer control, then focused with precision to carry out the cut: the material melts instantly upon contact with the beam. The process is completed by moving the laser beam and the sheet along a predetermined “cutting path.” There are many benefits to using laser engraving techniques. We’ve already mentioned the cleanliness of the cut, which requires no further finishing: the precision is extremely high, also due to the low thermal impact on the surfaces. This allows for the creation of highly complex shapes that require no additional work (cutting edges come out glossy and millimeter-precise). The laser can be used on various types of metals, and its concentrated light beam allows for maximum precision on limited surfaces. It is an ideal method for sheet metal processing, both for cutting and welding. This is a technology that delivers speed and high effectiveness, regardless of material hardness. It can also be used on coated materials as well as semi-finished products.
Machines for Laser Engraving
Choosing laser cutting as a machining method involves the use of specific equipment, typically consisting of a cutting head (or oscillator), a multi-axis system that supports the head, and a shielded structure designed to protect operators and prevent accidents (ensuring the laser beam stays controlled). The system is also equipped with a numerical control unit that coordinates the machining process. The structure that supports the workpiece—and the necessary clamps—varies depending on the type of machining and the material being processed (tubes, flat sheets, or 3D objects). Laser cutting machines can operate independently, or they can be integrated into automated lines equipped with loading/unloading systems or into production lines that include additional operations such as punching, bending, or paneling.
