From the application of global laser products, the data processing industry is still its main application market, accounting for 35.2%; the communications industry ranked second, its share of 30.6%; In addition, the data storage industry occupies a third place, with a share of 12.6%.
Compared with the traditional processing technology, the laser processing technology has the advantages of less data, more cost effect in the scope of consumption and a strong adaptability to the processing object. In Europe, the high-end car shell and base, aircraft wings and spacecraft fuselage and other special data welding, the fundamental use of laser technology.
1, laser power density, the workpiece absorption laser temperature rapid rise and condensation or vaporization, even if the high melting point, hardness and brittle material (such as ceramics, diamonds, etc.) can also be used for laser processing;
2, laser head and workpiece do not contact, there is no processing tool wear problem;
3, the workpiece is not stress, not easy to pollute;
4, can the movement of the workpiece or sealed in the glass shell data processing;
5, the divergence angle of laser beam can be less than 1 MW arc, spot diameter can be small to micron level, action time can be short to nanoseconds and Picosecond, at the same time, high-power laser continuous output power can reach to 10-kilowatt magnitude, so the laser is suitable for fine micro-processing, but also suitable for large-scale data processing;
6, laser beam easy to control, easy with fine machinery, fine measurement technology and computer separation, complete the processing of high automation and reach a very high processing accuracy;
7, in the harsh environment or other inaccessible central, the robot can stop laser processing.
Laser processing belongs to Non-contact processing, and the energy of high-energy laser beam and its moving speed can be adjusted, so it can accomplish many machining purposes. It can be a variety of metal, non-metallic processing, especially the ability to process high hardness, high brittleness and high melting point of information. Laser processing flexibility is mainly used for cutting, surface treatment, welding, marking and punching and so on. Laser surface treatment includes laser phase transformation hardening, laser cladding, laser surface alloying and laser surface melting.
Laser processing technology mainly has the following common advantages:
① use laser processing, high consumption efficiency, reliable quality, economic benefits.
② can pass through transparent medium to the work piece in airtight container to stop various processing, in the harsh environment or other people inaccessible center, can use the robot to stop the laser processing.
③ Laser processing without "tool" wear, no "cutting force" action on the workpiece.
④ can be a variety of metal, non-metallic processing, especially the ability to process high hardness, high brittleness and high melting point of information.
⑤ laser beam is easy to guide and focus to transform all parties, and it is very easy to cooperate with CNC system to stop machining complex workpiece, so it is a very sensitive processing method.
⑥ non-contact processing, no direct impact on the workpiece, and therefore no mechanical deformation, and high-energy laser beam energy and its moving speed can be adjusted, so can complete a variety of processing purposes.
⑦ laser processing, the laser beam energy density is high, the processing speed is fast, and is part of the processing, to the non-laser mapping site has no or effect of minimal, thus, its heat affected area small, the workpiece thermal deformation small, subsequent processing capacity is small.
The divergence angle of the ⑧ laser beam can <1 the arc, spot diameter can be small to micron level, action time can be short to nanoseconds and Picosecond, at the same time, high-power laser continuous output power can reach the 10kW magnitude, so the laser is suitable for fine micro-processing, but also suitable for large-scale data processing. Laser beam easy to control, easy with fine machinery, fine measurement technology and computer separation, complete the processing of high automation and reach a high precision machining.
Laser processing technology has been widely used in many categories, with the laser processing technology, equipment, technology research into the depth of time, will have a broader application prospects. Because the heat of the input workpiece is small, the heat affected zone and the heat deformation are small, the processing efficiency is high and the automation is easy to complete.
