fiber laser cutting and typesetting notes
3. Nozzle design and airflow control technology
please calculate by following formula : V=8.2D2 (pg+1)
Fiber Laser cutting machine processing sheet metal burr what is the reason?Here we give you a simple analysis.
The working principle of fiber laser cutting machine, analysis of the resulting burr causes and solutions.
Solution:adjust the focus position, according to its offset position to adjust
Check whether the fiber laser cutting machine works properly. If not normal, it needs to repaire and maintain machine in time. If normal, check whether the output value is correct or not.
Solution: timely adjust and improve the speed of wire cutting
Solution: improve the purity of the auxiliary gas
Solution: focus debugging, timely adjustment
Solution: close the machine, restart and let the machine rest
The main reason of burr in laser cutting machine.when the laser cutting machine is working the workpiece, the laser beam irradiates the high energy produced on the workpiece surface,
so that the workpiece surface vaporization rapidly, and evaporation, to achieve the purpose of cutting. But there is a core device, we must attach importance to auxiliary gas.
The auxiliary gas is when the workpiece surface irradiation after gasification, blew the slag on the surface of workpiece,If the auxiliary gas is not used, the slag will be cooled and the burr will be formed on the cutting surface.
This is the main reason for burr formation
Another reason is the quality of the equipment itself, as well as the parameter setting factors, all customers after the purchase of laser cutting machine, must be professional operators debugging equipment.
So it’s important to choose a quality factory with good after-sale service .
Solution to burrs in sheet metal processing by laser cutting machine;
1.must be equipped with air compressor, the use of auxiliary gas to cut.
2.Find a professional operator debug laser cutting machine parameters until normal.
Anti-freezing work of laser cutting machine
Other than those used in fiber laser cutting machines.
they are also necessary for other laser equipment including laser marking,laser welding and laser engraving . Visible, the application of protective lenses market is very large.
1) Overall dimensions match, this is easy to understand;
2) Materials, according to different laser power, consider the use of cost.you can choose K9, quartz, in the practical application process,
professional manufacturers divide into two types of material into multiple levels.customers can choose the appropriate specifications according to actual needs.
3)Coating, laser antireflection film, according to the use of different coating technology parameters.
Although the protective lens of fiber laser cutting machine is vulnerable parts,
in order to improve its utilization rate and reduce the production cost.
You can clean the lens by regular cleaning, to achieve the purpose of recycling,
Pay attention to when dismantling: can not be too hard, can not collide with hard object.
Anti-reflective film on the surface, afraid of pollution, afraid of wet, afraid of oily, afraid of scratch.
It is required in the work to provide dry, to the oil air, do not directly handle laser cutting machine lens protection lenses, because the skin will have a permanent fat on the lens surface damage.
Instead, you can work with gloves and its special kit, and for smaller lenses, optical tweezers or vacuum tweezers are more convenient.
No matter what method to clip the laser cutting machine to protect the lens,must follow the non optical surface clamping, such as the frosted edges on the mirror plaque.
Because most of the contaminants and surface defects are relatively small in size, we often need to magnify the equipment when examining the lenses.
In addition to enlarging the equipment, sometimes we need to illuminate the optical surface with a brighter beam of light, enhancing the specular reflection of surface contaminants and defects, making it easier to spot contaminants and defects.
Use wet wipe the paper , do not dry to use.
In the softness of the consideration, the available wipe paper is cotton Webril wipe paper or cotton ball, lens paper, and cotton applicator applicator.
fiber laser cutting machine high efficiency, high quality, high degree of automation, applicable to carbon steel, stainless steel, silicon steel, galvanized sheet, aluminum alloy, copper and other metal materials of professional cutting.for the metal material cutting, hollowing, drilling and other processes to provide a strong technical support. then the laser products are suitable for metal processing in elevators and other industries, and can ensure the smoothness of the section at the same time as the rapid cutting of the elevator sheet metal fittings.
The guide should be often cleaned, excluding dust and other sundries, to ensure that the normal laser equipment rack to wipe regularly, add lubricating oil, time should make adjustments.Compared with the spring and Autumn period to shorten 0.5-1 time times, and maintain the observation of the oil quality, for high-temperature area work machinery to improve the viscosity of the engine properly, grease oil temperature easy to change appropriate refueling, to ensure that lubrication and no debris. Carefully check the laser cutting machine cutting track straightness and the verticality of the machine, found that the normal timely maintenance of debugging. Guide rails should be often cleaned and lubricating oil, the motor should also be regularly cleaned and on the lubricating oil, the machine in the road can better walk, more accurate cutting, cutting out of the product quality will improve.
