Processing principle of fiber laser cutting machine: the light emitted by the laser is reflected and focused to the workpiece surface through the reflector and focusing lens. The high temperature generated by the high energy light makes the workpiece melt and evaporate, forming a cut. The purpose of cutting and carving is achieved through numerical control displacement.
1、 Wide application scope and outstanding industrial application
As we all know, due to the increasing use of metal materials, the use of optical fiber laser cutting machine is more and more extensive. This exclusive laser cutting machine will be used in sheet metal processing, aviation, electronics, electrical appliances, automobiles, precision accessories, craft gifts, kitchenware and other industries. It is not difficult to find that in today's rapid development of the processing industry, stainless steel, carbon steel, aluminum, galvanized steel, iron and other metal materials can also be cut quickly, accurately and efficiently.
2、 Outstanding processing performance
Today, with the continuous development of science and technology, only continuous progress and the development of the times can effectively occupy the leading position in the market. First of all, we all know that the optical fiber laser cutting machine has high precision, fast speed and narrow slits, so the cut surface is smooth without burrs; Secondly, because the slit is very narrow, the heat affected zone is small, and it does not directly contact the metal material surface, so the workpiece will rarely have mechanical deformation.
In the metal processing industry with different shapes, thicknesses and materials, having such advanced, high-tech and high-quality optical fiber laser cutting machines is definitely a new leap in sheet metal processing.
3、 Safe, energy-saving, low investment and high return
1. Safe processing. For the optical fiber laser cutting machine, it belongs to non-contact processing, which solves the defect of deformation caused by mechanical pressure on the workpiece caused by traditional metal processing, and will not have any wear on the instrument and workpiece. Good cutting effect for coating and surface treatment.
2. Save resources. Since laser cutting has a high dressing capacity and can adapt to the change of production capacity, the processed workpieces do not need further processing (polishing, deburring, finishing, etc.). From the perspective of production, further labor costs and processing costs are saved, and production efficiency is greatly improved.
3. Low cost processing. Compared with other cutting equipment, the fiber laser cutting machine is faster, and the use cost is only lower than that of traditional equipment. The fiber laser can also reduce the use of lenses, greatly reducing the production and maintenance costs.
4. High flexibility. The optical fiber laser cutting machine does not need mold opening and manual operation, and can save a lot of money on production costs. On the other hand, metal laser cutting machine can cut various complex graphics. Just input the drawings to the control console, and the machine tool will automatically process the desired graphics.
5. Environmentally friendly processing, the optical fiber cutting machine has less processing waste, low noise, clean, safe and pollution-free, which greatly improves the working environment.
During the use of optical fiber laser cutting machine, the addition of auxiliary gas is essential! You should pay attention to these when using auxiliary gas:
air
Air can be directly supplied by air compressor, so it is very cheap compared with other gases. Although the air contains about 20% oxygen, the cutting efficiency is far less than oxygen, and the cutting capacity is similar to nitrogen. A small amount of oxide film will appear on the cutting surface, but it can be used as a measure to prevent the coating layer from falling off. The end face of the incision is yellow. The main applicable materials are aluminum, aluminum alloy, stainless copper, brass, galvanized steel plate, non-metal, etc.
nitrogen
When some metals are cut, oxygen will form an oxide film on the cutting surface, and nitrogen can be used for non oxidizing cutting to prevent the appearance of oxide film. The oxidation free cutting mask can be directly welded and coated, and has strong corrosion resistance. The end face of the incision is white. The main applicable plates are stainless steel, galvanized steel plate, brass, aluminum, aluminum alloy, etc.
oxygen
It is mainly used for cutting carbon steel with laser cutting machine. When the oxygen reaction heat is used to improve the cutting efficiency in large format, the oxide film produced will improve the beam spectral absorption factor of the reflective material. The end face of the incision is black or dark yellow. It is mainly applicable to rolled steel, rolled steel for welding structure, carbon steel for mechanical structure, high tension plate, tool plate, stainless steel, electroplated steel plate, copper, copper alloy, etc.
argon 
Argon is an inert gas, which is used to prevent oxidation and nitridation in laser cutting, and also used in welding. Compared with other processing gases, the price of argon is japonica rice, which increases the cost accordingly. The end face of the incision is white. The main applicable materials are titanium, titanium alloys, etc.
