Learn about laser cutting machines

What is laser cutting?

Fiber laser cutting machines use the heat generated by lasers to cut materials. Generally, the optical principle is used, and the CNC computer display screen is used to process the material through melting, burning, evaporation and other processes to achieve the purpose of cutting.

Advantages of laser cutting machines

  • Compared with the traditional cutting process, the later secondary processing process is reduced;
  • Fast speed and high precision can improve work efficiency and save costs for enterprises;
  • The cutting graphics are not limited and any image can be cut;

Laser cutting materials guide

There are many types of laser cutting machines on the market, which can not only cut metal but also non-metal. The following article lists the most common laser cut materials in the industrial market.

Metallic material:

Fiber laser cutting machines are generally used for cutting metal materials to cut metal plates and pipes. Common metal laser cutting machines include fiber laser cutting equipment and CO2 laser cutting machines. The cutting effect is related to the laser power, fiber laser, thickness of the cutting plate, etc.

Fiber laser cutting equipment can cut brass, stainless steel, carbon steel, aluminum plates, nickel and tungsten plates. In addition, some auxiliary gas, nitrogen or argon, is required during cutting, which needs to be determined according to the condition of the plate.

Carbon steel plate

At present, the thickness of carbon steel plates on the market can reach 200mm, which requires high-power metal cutting equipment of 10,000 watts. The thinnest plates can be as thin as 0.1mm. Especially when cutting low carbon steel, the cutting surface is smooth and flat, and the heat affected zone is small.

Stainless steel:

For stainless steel plates, the thickness can be cut up to 6mm. The higher the power, the thicker the cutting thickness, and the better the laser cutting effect. YAG laser cutting equipment can also be used.


Because aluminum is a high-gloss material, when laser cutting, you need to use a highly reflective fiber laser. In addition, auxiliary gas is required for cutting.

Alloy steel:

The laser cutting machine has good quality when cutting alloy steel, but there will be a certain amount of slag when cutting tungsten.

Brass and other metal materials:

Brass, like aluminum plate, is a highly reflective material and requires the use of a highly reflective laser.

Non-metallic materials

Plexiglass, acrylic, two-color boards, plastics, leather, fabrics, wood, etc. all require the use of CO2 laser cutting machines.


Laser cutting cardboard is generally used in the advertising or packaging industries, on exquisite decorative items or wedding invitations, with high precision and beauty.
Because cardboard is flammable, it needs to be in a well-ventilated environment when cutting.

Plastic products:

Transparent plastics such as acrylic, PMMA and Lucite can ensure a good edge finish when laser cutting. Diode laser cutting equipment and CO2 laser cutting systems are required.

Cutting power, thickness, and light frequency all have an impact on the cutting effect, because plastics will produce toxic gases, which have an impact on health, so health protection measures must be taken.


A relatively common material in the engineering field, it has high strength and stable performance. Can be used in gears, guide and sliding components, medical equipment, food packaging, etc. The co2 laser cutting system is better and can also be used for engraving.

POM is toxic when charred and requires similar laser setup as acrylic. Certain settings for the blower are also required.


Everyone knows that glass is fragile and reflective, and it can also be laser cut.

Factors to consider when using different laser cutter materials

Laser parameters:

  • Power size: Under normal circumstances, insufficient or too high laser power will not achieve the desired effect.
  • Laser wavelength: Different materials absorb different wavelengths of laser light differently.
  • Focus position: Incorrect focus position may result in poor cutting results.

Cutting speed:

Cutting speed has a great influence on the cutting effect.

Cutting materials:

Different materials have different corresponding reflection effects and thermal conductivities, which will affect the cutting effect;
Material surface: If there is a coating, it will be difficult to cut.

Auxiliary gas:

Different auxiliary gases (such as oxygen, nitrogen, air, etc.) will affect the cutting effect and speed.

Cutting technology:

The cutting path and cutting method (such as continuous wave cutting or pulse cutting) also affect the cutting effect.

Positioning accuracy:

The repeated positioning accuracy and mechanical accuracy of the equipment directly affect the cutting accuracy.


Can all materials be laser cut?

NO. Not all materials can be laser cut. PVC will produce toxic smoke, which is harmful to the body. In addition, ABS, high-density polyethylene and other plastics are prone to produce slag during the laser cutting process. When choosing laser cutting, be sure to consider the compatibility and safety of the materials being processed.

What are the advantages of laser cutting equipment?

  • High precision: Laser cutting equipment has high cutting precision. Compared with traditional cutting methods, it does not require secondary processing and has less hair residue;
  • Fast speed: different powers have different speeds;
  • Wide range: suitable for cutting a variety of materials, both metal and non-metallic;
  • Non-contact: no damage to materials;
  • Flexible: Any graphics can be cut without restrictions.

How to choose the right material?

  • Compatibility: Ensure that the cutting material can absorb the light source and improve cutting efficiency;
  • Material thickness: Different materials have different thicknesses and different absorption abilities of light sources;
  • Material properties: hardness, reflection, etc.

How to ensure laser cutting effect?

  • Parameter settings: Set reasonable laser power, speed, and focus position;
  • Selection of auxiliary gas: Different auxiliary gases have an impact on the cutting effect;
  • Regular maintenance: If the equipment is old, it will be difficult to ensure accuracy during use;
  • Training of technicians: Operators should operate according to the safe operation manual

Laser operating safety guidelines:

  • Wear laser goggles: The strong light produced by laser is harmful to human eyes, so protective measures are required;
  • Do not touch the skin with the laser: the laser energy is too high and will penetrate the skin;
  • Routine maintenance of equipment: Regular maintenance and protection of equipment;
  • Work area safety protection: The work area is clean and free of debris;
  • Comply with operating procedures: technicians follow the laser operating manual during operation.
