Application Advantages
Cutting quality
(1) Laser cutting kerf narrow, you can save raw materials,
(2) vertical slit is good, smooth surface. Without subsequent reprocessing process and the cleaning process can be used for forming and welding parts;
(3) Eaves no glitches, no mechanical stress. Small heat-affected zone, almost no distortion
(4) Laser cutting aspect ratio. The metal material of up to 20: 1 or so for non-metallic materials up to 100: 1 or more.
Cutting process
(1) Laser cutting speed. Low noise. Pollution;
(2) the cutting process, no "tool" worn question, in all material suitable for Taiwan;
A cutting-piercing
Any kind of thermal cutting technology, except in a few cases can be started from the outside edge of the board, they are generally required to wear a hole in the plate. Before the laser punch press machine is used to punch out a hole, and then use the laser from the hole to begin cutting. No punching apparatus for laser cutting machine has two basic methods of perforation:
Pulse perforation - using high peak power pulsed laser to melt or vaporize a small amount of material, commonly used as an auxiliary air or nitrogen gas, in order to reduce the exothermic oxidation so that the hole expansion, the gas pressure is relatively small oxygen pressure when cutting. Each laser pulse produced only small particle injection, the gradual deepening of the time and therefore slab perforation takes a few seconds. Once the piercing is completed, immediately replaced by oxygen assist gas for cutting. Such smaller diameter perforation, perforation quality is better than blasting perforation. Lasers used for this purpose should not only have a high output power; more important is the time and spatial characteristics of the beam, in addition to the pulse perforation must have more reliable pneumatic control system, in order to achieve the kind of gas, gas pressure switch and control perforation of time.
Blasting perforated - material after continuous laser irradiation to form a pit in the center, and then the laser beam coaxial oxygen flow quickly to remove the molten material to form a hole. Usually hole size and sheet thickness, average diameter thickness of blasting perforation half, so the thick plate blasting hole diameter is large, and not round, not in the use of high precision machining parts, only with on waste. Furthermore, since the same used for perforation and cutting oxygen pressure, a large splash.
Second, cutting analysis of the deformation of holes
This is because the machine is not taken in the processing of small holes perforated blasting way, but with the way the pulse perforation, which makes the laser energy in a small area is too concentrated, the non-processing area also burned, resulting in deformation of the hole, affecting the processing quality. At this time we should be in the pulse mode processing program to blasting perforated punch way to solve them. For small power laser cutting machine is just the opposite, when machining small holes perforated in the way to take the pulse in order to achieve a better surface finish.
Third, non-normal spark when cutting mild steel
This situation will affect parts of the cutting section finish processing quality. At this time in the other parameters are normal circumstances, we should consider the following: loss laser head nozzles NOZZEL, the nozzle should be replaced. In the absence of new nozzle replacement, should increase cutting working gas pressure; nozzle laser head screw loose connections. It should immediately suspend cutting, check the connection status of the laser head, Reattach thread.
Fourth, the laser does not completely cut through state analysis
After the analysis can be found in the following several cases are processed mainly produce unstable situation: the laser head nozzle selection and processing thickness does not match; laser cutting line speed is too fast, reduce the need to operate the control line speed; induction nozzles are not allowed to guide to the laser focal position error is too large, need to re-test the induction nozzle data, especially when cutting aluminum the most prone.
Fifth, laser cutting mild steel, the workpiece of glitches
The laser cutting operating and design principles, the analysis results the following reasons is the main cause of the workpiece glitches: the vertical position of the laser focal point is incorrect, the focal position of the test needs to be done, be adjusted according to the focus offset; laser The output power is not enough, you need to check whether the laser generator is working properly, and if normal, then observe the output value of the laser control buttons is correct, to be adjusted; cutting the line speed is too slow, we need to increase the line speed at the time of the operation control; cutting purity gas is not enough, the need to provide high-quality cutting working gas; laser focus shifted focus position of the test needs to be done, be adjusted according to the offset of the focus; instability machine appears to run too long, then the need to shut down again start up.
