A Close Look At the Laser Cutting Machine GuideďźšInvisible light beam has replaced traditional cutting devices in laser cutting machine, which is characterized with high accuracy, speediness, no limit in cutting pattern, material saving, smooth incision and low cost, etc. Laser cutting machine is developing to replace traditional metal cutting equipment. As reported by OFweek Laser: The working process of laser cutting is to transform the emitted laser to high power density laser beam by optics system. The laser beam irradiates workpiece surface and make its temperature to melting point or boiling point; at the same time the coaxial high pressure gas blows the melt metal or gasification away. As the light beam and workpiece move, their relative position forms a kerf, thus complete the cutting.
Invisible light beam has replaced traditional cutting devices in laser cutting machine, which is characterized with high accuracy, speediness, no limit in cutting pattern, material saving, smooth incision and low cost, etc. Laser cutting machine is developing to replace traditional metal cutting equipment. As the most popular industrial cutterbar in the 21st century, powerful laser cutting machine has been introduced to various fields gradually and becomes a good helper in manufacturing. What kind of materials can be applied in laser cutting machine? There are metallic materials and nonmetallic materials processing: A: Metal laser cutting machine can be applied in board cutting, punching and carving, including materials like stainless steel, iron, aluminum, copper and other alloy plates. Among them, stainless steel is the easiest to cut, but only for thin ones; it is unable to cut the ones thicker than 4mm. The kerf can be as narrow as 0.1mm, so the cutting has no harm to the material and the kerf is smooth with good perpendicularity. The cutting thickness of carbon steel can reach to 20mm, which is thicker than stainless steel. Because laser has a little heat effect on carbon steel, it has perfect cutting effects. Side trimming quality of high-carbon steel is better than that of low-carbon steel, but the former has larger heat effect area. Most alloy materials can be cut, with corrosion and slag adhesion on a few materials. It is difficult to cut copper by laser. Even if
possible, the copper need to be very thin.
B: Non Metal Laser Cutting Machine can be applied in materials as cloth, leather, acrylic, plank, paper, rubber, silica gel, EVA, sponge, glass and so on. Compared to mental laser cutting machine, nonmetallic laser cutting machine has more functions and can be used in more different materials. It has no limit on the materials' size and pattern, and the price is relatively lower.
The thick plate cutting capacity of domestic laser cutting machine is far behind the overseas high-end equipment. The main reason is the inadequate knowledge about nozzle and air streams. Among the numerous factors that influence the cutting effects, the nozzle's air streams flow field is the most difficult to analyze. Especially for carbon steel, it's cutting needs combustion-supporting oxygen, whose flow field distribution has very obvious influences on the cutting effects. Most overseas laser cutting machine manufacturers have solid technical reserves and a large amount of researches in this aspect, but very little researches in China. When buy a laser cutting machine , buyers should recognize its core configuration which is an important index to measure its performance. The laser cutting machine industry has also been effected by economic crisis, since it is mainly applied in industrial manufacturing. The decline of manufacturing field will directly cut down the amount of sales. Moreover, the domestic laser cutting technology mainly relies on Europe and US and the industrial distribution is uneven excess capacity in some fields and insufficient inventories in some other fields. More and more factories will go broke and merger and acquisition will occur in succession. Regarding the laser cutting machine processing system, there is still big gap between China and other developed countries. The sales amount is only 2% of the global total
amount. In a word, laser cutting processing equipment still belongs to sunrise industry and its profit is higher than traditional industry in general.
