Laser cutting or engraving is a process which makes use of laser light to engrave objects. This type of laser engraving may also be called laser cutting. Laser cutting machines typically include laser source power, a laser energy detector (LED) and an ionization chamber and an application device. In this instance, the laser cutting head isn’t part of the machine, but is an independent entity that is built right into the machine. This kind of laser cutting and engraving machines can be classified into different types.
The most well-known model is the CNC laser-cutting head. It is used for precise engravings even in small volumes. The mixing laser machine comes with distinct advantages over the regular CO2 laser cutting heads. It is capable of cutting both non-metal and metal materials (wood brass, MDF, etc.). The machine is equipped with an automatic focusing system, which allows it to precisely locate the focal point within the material in order to cut it. This model also includes an accessory known as the “engraver wheel” that allows you to rotate the workpiece as the laser beam is working.
The other major type is the CNC laser cutting head movements, which are usually utilized in larger-scale operations. This type of cutting head for lasers can be moved in either a linear or rotary mode according to the type of operation. The rotary mode moves the cutting head across the workpiece while it cuts, while the linear mode is the one that moves the material in one direction.
Continuous Laser Engraving (CEL) is a technique used when the operation requires precision. The laser beam makes lines on the materials to be engraving. This type of engraving has advantages over the other techniques in terms of accuracy since it doesn’t require the use of moving components or gears. In CEL laser engraving, the laser beam is transmitted continuously over the workpiece. The line width can be adjusted to the thickness of the workpiece. The computer program allows the angle and position to be controlled automatically. This allows the workpiece’s movement to be precise and stable without any manual effort.
Another crucial aspect to take into consideration when purchasing laser engraving equipment is the machine’s focal length. Lenses determine the depth of the laser pattern that is projected onto the workpiece. A longer lens focal length allows for more details on the engraved metal , and also prevents the engraving from blurring.
Mixed laser cutting machine ( MLB) is a combination of a highly-powerful co2 laser tube and a fiber optic feed. The co2 laser tube with high power produces stronger and more intense light than the regular fiber optic tube, which in turn allows for an easier and more precise cutting path. The fiber optic feed allows the two-way synchronous laser communication between the co2 laser tube and the computerized CNC machine. Because of the high-power co2 laser tube, the detailed patterns produced are of a superior quality than those created by a traditional CNC machine. Some manufacturers combine a traditional CNC machine with an MLT (medium laser cutting) system in order to create smaller pieces of metal. Manufacturers can also combine a standard CNC machine with a high-power CO2 laser tube, which is coupled with fiber optic feed. Learn more about Laser CNC Engraving and Marking now.
Fiber Optics and a high-power Co2 Laser Tube. The combination of these two technologies makes for a high quality of cut-depth as well as output power, and the accuracy of the final product is close to that of a standard CNC machine. The primary difference between the CNC machine and a MLT is that the latter produces focused beams, which means that they operate in one direction. Due to their focused output that is why the high-power fiber optic output of CNC machines is not needed, and consequently it does not necessary rely on a correlated laser focus. In a CNC machine, the output of the laser beam directly controls the movement of a drill bit, which enables the system to be more precisely controlled; however, because of the previously mentioned dependence on a correlated laser focus, the accuracy of the cut is contingent upon the output power of the laser itself and not the fiber optic feed.
A multi-mode laser focussing cutter. The MLT is combined together with a high-power fiber optical output and an CNC lazer to provide an synchronous, two-way laser communication. This allows CNC machines to simultaneously program laser lengths and cutting depths, as well as feed rates. These processes are dependent on one the other and, due to the intricate communication between machine and NCC cutter, this combination is often referred to a “quadrate”, or “fiber laser auger”.
