Laser Engraving Options

Laser cutting or metal engraving is a process wherein the light output of lasers is engraved on metal objects. Laser cutting is also referred to as this kind of laser engraving. Laser cutting machines typically include the power source for the laser, a LED, an ionization chamber, an application device and a laser energy detector (LED). The laser cutting head is an autonomous unit that is part of the equipment. This kind of laser cutting or engraving machine can be classified into various kinds.

The most common kind is the CNC laser cutting head, which is often employed for low-volume precision engravings. The mixing laser machine comes with many distinct advantages over the standard CO2 laser cutting head-it is capable of cutting both metal and non-metal material (wood brass, wood, MDF, etc.). The machine has an automatic focusing system, which allows it track the location of the focal point within the material in order to cut it. This model comes with an accessory called the “engraver wheel” that allows you to rotate the workpiece as the laser beam works.

The other type is the CNC laser cutting head motions, which are commonly utilized in larger-scale operations. This type of cutting head for lasers can be moved in either the rotary or linear mode depending on the specific operation. The rotary mode is when the cutting head moves across the work piece as it cuts, whereas the linear mode moves the material in one direction at one time.

If the task requires precision, then the Continuous Laser Engraving (CEL) technique is employed. The laser beam produces lines on the surface to be engraved. This type has an advantage over the other methods in terms of accuracy as it does not require any moving components or gears. CEL laser engraving projects the laser beam continuously across the workpiece. The line width can be adjusted to the thickness of the workpiece. Through the use of a computer program, the angle and the position of the laser beam can be automatically controlled, allowing the workpiece to move precisely and securely, without the necessity of manual effort.

The other important factor to be considered when buying a laser engraving machine is the lens 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 provides more fine detail on the engraved metal and helps prevent the engraving from blurring.

Mixed laser cutting machine ( MLB) is a combination of a high-power co2 laser tube and fiber optic feed. The high-power co2 laser tube can create stronger and more intense light than the standard fiber optic tube, which in turn allows 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. The intricate patterns made by the co2 laser tube are more precise than those created by a traditional CNC machine. Certain manufacturers combine a standard CNC machine with an MLT (medium laser cutting) system, in order to produce more precise pieces of metal. There are also manufacturers who combine both a standard CNC machine with a high-power co2 laser tube as well as a fiber optic feed. Learn more about Laser Cutting Machine here.

Fiber Optics and a high-power CO2 Laser Tube. Combining these two technologies produces a high level of cut-depth and output power, as well as the finished product is similar to a conventional CNC machine. The primary difference between the CNC machine versus a MLT is the fact that the latter produces focused beams. This means that they can only operate in one direction. Due to their focused output, the high-power fiber optic output of a CNC machine is not necessary, and so it does not necessary depend on a correlated laser focus. The output of the laser beam of a CNC machine directly influences the movement of a drill bit. This allows the system to be more precisely controlled. However due to the dependence on a correlated laser focal that is, the laser’s output strength and not the fiber optic feed, the precision of the cut is dependent on the power output of the laser.

A mixed mode focussing cutter. A MLT is paired with a fiber optic high-power output and a CNC laser in order to establish a two-way laser communication that is synchronized between the system and the CNC machine. In a CNC machine, this allows the machine to simultaneously set laser durations, cutting depths, and feed rates. These processes are dependent on each the other and, due to the intricate communication between the machine and the NCC cutter, this configuration is often referred to as a “quadrate”, or “fiber laser auger”.
