Basically when cutting with the laser the beam is focused on the material through the hole in the nozzle. This heats the material and melts it. A cutting gas, which as a rule flows co-axially through the nozzle, removes the molten material.
Laser Cutting is an innovation that uses a laser to cut materials and is regularly utilized for modern assembling applications. Laser cutting machine works by coordinating the yield of a powerful laser most usually through optics. CNC laser cutting is utilized to coordinate the material or the laser beam created. Driving Laser cutting companyand a standard business laser for cutting materials would include a movement control framework to take after a CNC or G-code of the example to be cut onto the material. Modern Laser cutters are utilized to cut level sheet material and in addition basic and channeling materials.

The laser cutting service or process uses a strong focused laser beam, produced by a laser diode. The high energetic laser beam heats the surface of the material and melts rapidly a capillary in the material. The diameter of the capillary responds to the diameter of the used laser. During the cutting process, an assistant gas is used to eject the molten material from the kerf. As a result, the cut quality and speed are very high compared with other cutting technologies.
You can choose between three basic types:
With sublimation cutting, the laser beam brings the material to its vaporisation point directly (Sublimation). An inactive (inert) cutting gas such as Nitrogen forces the molten material out of the cut. Typical materials are, amongst others, wood and plastic. Thin metals can also be cut in this way.
Flame (oxygen cutting) by contrast, is characterized by the fact that the material is only heated to its ignition temperature. Oxygen is used as cutting gas, so that the material burns and forms an oxide which melts through the additional energy from burning. The cutting Oxygen then forces the slag out of the cut. Typical material is, for example, low alloy steel (Mild Steel).
For fusion cutting, the material is melted directly by the laser beam. As with sublimation cutting, an inert gas, usually Nitrogen, is also used here to force the molten material out of the cut. This process is typically used for alloyed steels (Stainless Steel).
All processes have in common that, because of the narrow focus of the laser beam, the width of cut (kerf width) is very small compared to the other thermal cutting processes. Thus minimum material is melted and the laser energy is used very efficiently. The heat input into the material is thus relatively low so that even small geometries can be cut.
In addition, the cut edge is relatively straivght which in all gives very high component accuracy from the cutting process.
This means that laser cutting system is used in the most diverse areas, specifically wherever high accuracy for the component geometry and the cut edge is required. The preferred range for steel sheets is up to a material thickness of 20 mm, under certain circumstances up to 25 mm. For this application mainly the CO2 Laser and Fiber Laser are used. For greater thicknesses, laser cutting only makes sense for special applications, more usually other cutting processes (oxyfuel or plasma cutting) are used here.
Plate thickness: 0.1 mm up to 50 mm
Typical: 0.5 mm up to 25 mm
- Laser light can be well focused from 50 mm to 0.2 mm
- Laser radiation: coherent, monochromatic, high energy
- Very high power density (some MW/cm2)
- The light melts or partially vaporises the material and an additional gas stream blows it away
- High to medium cut quality (roughness)
- Smooth to rough, vertical planes of cut
- Metallurgical perfect surfaces (oxidized) or metallically blank surfaces (high pressure inert gas cutting)
- Low heat input
- High to low cutting speeds
- Hardening within the area of the Heat-Affected-Zone (HAZ) (small)
- Dust as well as UV and IR-radiation
