What are the laser precision machining applications
At present, the transformation and upgrading of the traditional manufacturing industry is facing a depth, high value-added, high technical barriers more high-end precision machining is one of the important direction.
As the growing demand for the high precision machining, precision machining technology is also associated with the rapid development of the laser technology is getting more and more recognition in the market.
Laser processing technology according to the size of processed materials and machining accuracy requirement of three levels: mainly medium plate material of large pieces of laser processing technology, the machining accuracy in millimeter and submillimeter level;
Is given priority to with sheet precision laser processing technology, the machining accuracy is in commonly 10 micron grade;
Under 100 microns in thickness of film laser micro machining technology, the machining accuracy is in commonly 10 micron or sub-micron.
Today, we mainly introduce precision laser machining.
Laser precision machining can be divided into four types of applications, precision cutting, precision welding, precision punching and surface treatment.
Under the current technology development and market environment, the application of laser cutting, welding, 3 c electronic, new energy battery is the most current application field.
Laser precision cutting laser precision cutting is the use of pulse laser beam focused on the machining surface, form high energy density flare, with instantaneous high temperature melting or gasification materials processed.
The process is characterized by fast speed, incision smooth level off, generally no subsequent processing;
Cutting heat affected zone small, plate deformation small, processing of high precision, good repeatability, does not damage the material surface.
Apple mobile phone screen compared with high-power laser cutting, precision cutting according to the general processing object using nanosecond, picosecond laser, can focus on ultrafine space area, at the same time has a very high peak power and a short laser pulse, involved in the process of machining to space around the range of materials, to do the processing of 'super fine'.
In cutting, fingerprint identification the phone's screen, LED stealth scribing, etc in the production process of high degree of precision requirements, laser precision cutting technology has incomparable advantages.
Laser precision welding laser welding is of high intensity laser beam radiation to processed products work area, through the interaction between laser and material, fast to be welded to form a more density of heat source area, the heat energy to be welding area after the consolidation of the cooling crystallization molten or weld joint.
Its characteristic is not to need to electrodes and filler material, is a non-contact welding.
For high melting point of refractory metal thickness or different material for welding.
In the field of new energy battery, along with the development of new energy vehicles, power battery demand continues to increase.
Welding in the field of laser welding as power battery standard, in the very front of the ear welding, bottom cover, top cover and seal in the central part of the nail welding, in the back of the battery connector, such as the cathode sealing welding are widely used.
And in the field of 3 c, various modules, medium plate, plate, etc. , are inseparable from the laser precision welding technology.
Laser precision drilling laser precision punching is to reduce the light spot diameter micrometer, so as to obtain high laser power density, can in almost any material on laser drilling.
Its characteristic is in high hardness, brittle or punched on the soft material, aperture small, processing speed, high efficiency.
PCB drilling samples is the most widely applied in PCB industry, laser drilling compared with the traditional PCB drilling technology, laser processing speed, not only on the PCB still can achieve the traditional equipment can not be achieved under 2 microns, microporous and stealth hole drilling of holes.
And in the electronic product surface, also can be used for the phone's speaker, microphone, and other drilling on the glass.
Laser surface treatment of laser surface treatment is the use of high power density of laser beam was carried out on the metal surface treatment, can be realized on metal amorphous phase transformation hardening, surface, surface alloying, or make the surface material vaporization or change the color of chemical reaction, thus change the surface properties of metallic materials.
Its characteristic is the need for additional material, just change the organizational structure of the processed material surface layer, be processed parts deformation, suitable for the surface markers and high precision parts processing.
Laser surface treatment can be divided into two categories according to whether to change the base material composition.
Without changing the application of base material composition with laser quenching (
Phase transformation hardening)
, laser cleaning, laser shock hardening and laser polarization and so on, the change of base material composition, including laser cladding, laser plating, laser alloying and laser vapor deposition, etc.
