Key Takeaway

  • CO2 laser cutter machines have more advantages in  non-metallic materials.
  • Fiber laser cutter can only used in metals, not non-metals such as  wood, cloth, leather, and stone.

The wavelength of CO2 lasers is 10.6um, which is more easily absorbed by non-metals, and can cut non-metallic materials such as wood, acrylic, PP, and plexiglass with high quality.

The wavelength of fiber laser cutting machines is 1.06um, which is not within the absorption range of the above materials, or the absorption is not appropriate, and the ideal cutting effect cannot be achieved.

Therefore, the application advantages of fiber laser cutting machines in non-metallic cutting are not very obvious at present.

Is there a machine that can cut both metals and non-metals? Let’s keep reading

1. working principle

  • Working principle of CO2 laser cutting machine:
  • The laser power source drives the laser tube to emit light, which is refracted by several reflectors to transmit the light to the laser head, and then the focusing lens laser head installed on the laser head converges the light into a point that can reach an extremely high temperature, so that the material instantly sublimates into gas and is sucked away by the exhaust fan, thereby achieving the purpose of cutting.
  • Working principle of fiber laser cutting machine:
  • Fiber laser cutting machine is a laser cutting machine that uses a fiber laser generator as a light source.
  • It is a new type of fiber laser that can output a high-energy-density laser beam and focus it on the surface of the workpiece, so that the workpiece is instantly melted and vaporized by the ultra-fine focus spot irradiation area, and the spot irradiation position is moved by the CNC mechanical system to achieve automatic cutting with fast speed and high precision.

2. Application

  • Fiber laser cutting machines are widely used in electronics, electrical appliances, mechanical hardware, new energy equipment, solar energy, LED, automobile and other industries.
  • It is good at processing common metal products in daily life, such as advertising metal characters, kitchen utensils, environmental protection equipment, etc.
  • Widely used in stainless steel, carbon steel, alloy steel, copper, brass, silicon steel, galvanized steel, nickel-titanium alloy, chromium-nickel-inconel alloy, titanium alloy, etc.
  • CO2 laser cutting machine, capable of engraving and cutting various non-metals, such as acrylic, marble, wood, density board, plywood, textiles, leather, glass, paper, etc.
  • Laser cutter CO2 widely used in many industries such as crafts and gifts, souvenirs, Chinese paper-cuts, billboards, clothing, furniture, etc.

3. Hybrid laser cutting machine

Type 1：Single cutting head

  • This machine uses CO2 laser as the laser source, and a special laser head that can cut metal on the basis of the standard CO2 laser cutter machine.
  • This hybrid metal laser cutting machine can be widely used in the cutting of non-metallic materials and metal sheets, with smooth cutting edges and no burrs.
  • This  hybrid laser cutter has fast processing speed, high precision and high efficiency.
  • The running speed is fast, the laser energy is adjustable in real time, and the operation is very simple.
  • Common machine sizes are 1390/1610/1325/153
  • Type 2：Double cutting head laser generator
  • Combine two laser sources, fiber laser generator and CO2 laser tube, into one machine for cutting.
  • Use two systems to control the fiber laser cutting head and CO2 laser cutting head respectively to achieve metal and non-metal cutting.
  • The CO2 & fiber 2-in-1 metal and non-metal laser cutting machine adopts a gantry structure.
  • which has the advantage of being equipped with two independent control systems to control the fiber laser and CO2 laser respectively.
