With front tank industry continues to develop, more and more industries and enterprises use to laser cutting machines, laser cutting is the use by focusing high power density laser beam irradiation of the workpiece to be irradiated materials rapidly melting, vaporization and ablation or achieve ignition. At the same time with coaxial with the beam of high speed airflow blow in the molten material, so as to realize the workpiece cut.

Laser cutting can be divided for laser vaporization cutting, laser fusion cutting, laser oxygen cutting and laser scribing and breaking control four categories; general characteristics are cutting speed, high quality, summarized as the following points:

The good cutting quality

Because of the small laser spot, high energy density and fast cutting speed, laser cutting can get better cutting quality..

The cutting efficiency is high due to the transmission characteristics of laser, laser cutting machine is generally equipped with multiple NC worktable, the whole cutting process can achieve full CNC. Operation, simply change the numerical control procedures, can be applied to different parts of the cutting, both two-dimensional cutting, but also to achieve three-dimensional cutting.

The cutting speed

Laser cutting 1200W thick carbon steel with power 2mm, cutting speed can reach 600cm/min; cutting 5mm thick polypropylene resin plate, cutting speed of up to 1200cm/min. Material in the laser cutting do not need to clip a fixed, can save the fixture, but also saves the upper and lower material auxiliary time.

The non-contact cutting

Laser cutting torch and workpiece without contact, there is no tool wear. Different parts of the processing, do not need to replace the cutter, simply change the output parameters of the laser. Laser cutting process noise is low, vibration is small, no pollution.

The cutting material types

Compared with the oxygen acetylene cutting and plasma cutting, the laser cutting material includes metal, nonmetal, metal base and nonmetal metal matrix composites, leather, wood and fiber etc.. But for different materials, because of their own thermal physical properties and the absorption rate of laser, different laser cutting adaptability is demonstrated..

With the advantages of many advantages, the use of the range and more and more companies, but the shortcomings of laser cutting equipment can not be ignored:

Due to the limit of laser power and size of the equipment, laser cutting cutting only medium and small thickness of plates and tubes one defect laser cutting and with the increase in the thickness of the workpiece, cutting speed decreased significantly.

2 industrial laser cutting plane sheet material and pipe material, often produce harmful gases, as well as various types of smoke particles containing oxide. The size of the particles can affect the toxicity of smoke, and the smaller particles are more dangerous.. Gas (the most common carbon dioxide and ozone concentrations) produced by many processes are harmful to human body.;

3 smoke and gas generation rate with alkali metal, flux, and filler composition changes and rate and welding or

Cutting depth. Cutting dust harm to operators: because of formation rate, duration, and operating frequency, practical work (especially distance from the breathing zone of the plume flow), and ventilation effect of these different factors, harm degree.

Therefore, in the laser cutting equipment is widely used in the application of industrial dust removal equipment, industrial dust can be applied to any flame / laser cutting dust generated in the dust, dust. Can effectively absorb dust and oil mist generated during the laser cutting process, the dust and odor will be minimized, harmless. Large capacity in addition to smell filter design, improve the service life, laser machine lens protection, avoid dust particles scratch the lens, of particulate absorption efficiency of 99.99%, and through professional chemical filter effectively remove poisonous and harmful gas in the waste gas, to ensure the staff to operate the environment from pollution. It can be seen that laser cutting equipment and industrial vacuum cleaners must not be divided;
