Laser cutting or metal engraving is a process wherein the laser light’s output is engraved on metal objects. This type of laser engraving can also be referred to as laser cutting. Laser cutting machines typically incorporate laser source power as well as a laser energy detector (LED) as well as an ionization chamber, as well as an application device. In this instance, the cutting head for lasers is not part of the machine but is rather a separate entity which is integrated into the equipment. This type of laser cutting or engraving machine can be classified into different kinds.
The most well-known type is the CNC laser-cutting head. It is used for high-quality engravings that are not large in volume. The mixing laser machine has many advantages over the traditional CO2 laser cutter head. It can cut non-metal as well as metal materials (wood and brass MDF and others.). The machine is equipped with an automatic focusing system, which allows it to precisely determine the exact location of the focal point within the material in order to cut it. This type also has an accessory called the engraver wheel, which is used to rotate the work piece while the laser beam is still operating.
The other type is the CNC laser cutting head movements, which are usually used in larger operations. In this case, the laser cutting head is moved in either its linear or rotation mode, according to the requirements of the operation. The rotary mode moves a cutting head across the workpiece as it cuts, whereas the linear mode moves the material in a single direction.
Continuous Laser Engraving (CEL) is a technique used when the process requires precision. The laser beam traces lines on the object being engraving. This method is more accurate than other methods due to the fact that it doesn’t require any moving parts or gears. CEL laser engraving transmits the laser beam continuously across the workpiece. The line width is set to a depth that is equal to the thickness of the workpiece. By the use of a computer program, the position and angle of the laser beam can be automatically controlled, allowing the workpiece to be moved precisely and securely, without the necessity of manual effort.
Another important aspect to consider when buying laser engraving machines, is the machine’s focal length. The depth of the laser pattern projected onto the workpiece is determined by the focal length of the lens. A longer lens focal length produces finer details on the engraved metal , and also prevents the engraving from blurring.
Mixed laser cutting machine ( MLB) is a combination of a high-power co2 laser tube and fiber optic feed. The co2 laser tube with high power produces stronger and more intense light than the typical fiber optic tube which allows for an easier and more precise cutting path. Fiber optic feed permits two-way simultaneous laser communication between co2 laser tube (and the computerized CNC machine). Because of the high-power co2 laser tube, the detailed patterns created are of superior quality than those created by a traditional CNC machine. In order to produce finer pieces, some manufacturers mix a standard CNC machine with a MLT (medium-laser cutting) system. There are other manufacturers who combine both an ordinary CNC machine with a powerful co2 laser tube, as well as a fiber optic feed. Know more about Laser CNC Engraving and Marking now.
Fiber Optics and a high-power CO2 Laser Tube. The combination of these two technologies allow for a high quality of cut-depth and output , and the precision of the finished piece is almost identical to the precision of a conventional CNC machine. The main difference between the CNC machine and a MLT is that the latter produces focused beams, meaning they can only operate in one direction. Because they produce an output that is focused, the CNC machine does not require a powerful fiber optic output. It also doesn’t require a laser focal. The output of the laser beam of a CNC machine directly regulates the movement of a drill bit. This allows the system to be more precisely controlled. However due to the above dependence on a correlated laser focus and the laser’s output, and not the fiber optic feed, the precision of the cut is dependent upon that laser’s output power.
A Mixed Mode Laser-focused cutter. A MLT is joined with a high-power fiber optic output and an CNC laser in order to create a two-way synchronous laser communication between the system and the CNC machine. In a CNC machine, this enables the machine to simultaneously program laser durations, cutting depths, and feed rates. These processes are dependent on one other , and due to the intricate communication between machine and NCC cutter, this configuration is often referred to a “quadrate”, or “fiber laser auger”.
