What is cnc laser cutter?  cnc laser cutter is a technology that uses a laser to cut materials, and is typically used for industrial manufacturing applications, but is also starting to be used by schools, small businesses, and hobbyists. Laser cutting works by directing the output of a high power laser most commonly through optics. The laser optics andCNC (computer numerical control) are used to direct the material or the laser beam generated. A typical commercial laser for cutting materials would involve a motion control system to follow a CNC or G-code of the pattern to be cut onto the material. The focused laser beam directed at the material, which then either melts, burns, vaporizes away, or is blown away by a jet of gas,leaving an edge with a high-quality surface finish. Industrial laser cutters are used to cut flat-sheet material as well as structural and piping materials.  There are many different methods in cutting using lasers, with different types used to cut different material.Some of the methods are vaporization, melt and blow, melt blow and burn, thermal stress cracking, scribing, coldcutting and burning stabilized cnc laser cutter.  Vaporization cutting  In vaporization cutting the focused beam heats the surface of the material to boiling point and generates akeyhole.

The keyhole leads to a sudden increase  in absorptivity quickly deepening the hole. As the hole deepens and the material boils,vapor generated erodes the molten walls blowing ejecta out and further enlarging the hole.Non melting material such as wood, carbon and thermoset plastics are usually cut by this method.  Melt and blow  Melt and blow or fusion cutting uses high-pressure gas to blow molten material from the cutting area, greatly decreasing the power requirement. First the material is heated to melting point then a gas jet blows the moltenmaterial out of the kerf avoiding the need to raise the temperature of the material any further. Materials cut withthis process are usually metals.  Thermal stress cracking  Brittle materials are particularly sensitive to thermal fracture, a feature exploited in thermal stress cracking.A beam is focused on the surface causing localized heating and thermal expansion. This results in a crack thatcan then be guided by moving the beam. The crack can be moved in order of m/s. It is usually used in cutting ofglass.  Stealth dicing of silicon wafers  The separation of microelectronic chips as prepared in semiconductor device fabrication from silicon wafersmay be performed by the socalled stealth dicing process, which operates with a pulsed YAG laser, the wavelength ofwhich is well adopted to the electronic band gap of silion.  Reactive cutting  Also called “burning stabilized laser gas cutting”, “flame cutting”. Reactive cutting is like oxygen torch cuttingbut with a laser beam as the ignition source. Mostly used for cutting carbon steel in thicknesses over 1 mm. This process can be used to cut very thick steel plates with relatively little laser power.

How cnc laser cutter work?

What is the working principle of cnc laser cutter?-cnc laser cutter is now the most advanced mechanical processing equipment, laser is first used in the field of mechanical processing, brought unprecedented promotion to the development of mechanical processing.

What is the working principle of cnc laser cutter?-A lot of people to the cnc laser cutter is not very understanding, most of whom were heard someone mentioned in the peer, but don’t know what was the basic working principle, let us give you a detailed explanation of the;

cnc laser cutter is mainly composed of two parts, one is the CNC work station, another is the machine tools.We can pass the CNC work station, processing drawings will need input, after the operation, will conduct instructions to the machine tools, machine tools will be according to the instruction work out to sheet metal design.

The core part of the machine tool is one of the laser generator, it is the core of the whole equipment.Why do you say so?Because it is the secret of the cut metal device.It can convert electrical energy into light energy, release the remarkable feats of laser beam, and with a lot of energy, laser beam by irradiation in sheet metal surface, make the light surface quickly reaching high temperature, radiation surface melting and evaporation of components, through the displacement of the cutting head to achieve the purpose of cutting and engraving.

Generally there are many kinds of cnc laser cutter laser, can according to different material to different kinds of cnc laser cutter.We have in common solid laser material as medium, its representatives have solid YAG cnc laser cutter.With gas as the medium of laser, its representative has CO2 cnc laser cutter.Based on optical fiber laser medium, its representatives have optical fiber cnc laser cutter.The three machining effect and the thickness is different.

Why cnc laser cutter?

Why we use cnc laser cutter?-cnc laser cutter includes different brands, so it cannot enumerate the advantages. Let me take this Fiber cnc laser cutter for example. Its features are the following:

Excellent beam quality: smaller focused spot makes more efficient work and cutting quality.

High cutting speed: its speed is twice of the same CO2 tube cnc laser cutter

High stability: the world’s top fiber laser generator makes stable performance, and the key components of the machine owns the life of up to 150,000 hours

High electro-optical conversion efficiency: fiber laser is three times higher than CO2 laser and saving energy

Low use-cost: the whole machine consume less energy, only 25%-30% of traditional CO2 laser machine

Low maintenance cost: no laser working gas, it is by fiber optic transmission, without lens reflecting, can save a lot of maintenance costs.

Smart operation and easy maintenance: optical fiber transmission, no need to adjust the optical path
