Sheet metal industry development is very rapid, and is becoming more and more important position in the market.
Advanced optical fiber laser plate cutting machine, will be increasing domestic sheet metal industry technology progress of the key.
It is not only to the enterprise brought huge economic benefits, also brought convenience to our life.
today, China laser equipment factory when the common problems in the optical fiber laser plate cutting machine put forward the corresponding solutions:
1.
Laser plate cutting machine cut punch skills to explore
any kind of eager to open technology, besides minority status to marginal beginning from the board, usually have to wear a hole on the plate.
In laser punching compound machine is to use the punch first rushed out of a hole, and then cut by laser from small beginnings.
and so on without stamping equipment iron plate cutting machine with two perforated ways:

Pulse perforation 】

China laser equipment factory fiber laser plate cutting machine with high power pulsed laser melt a few materials or vaporization, commonly used air or nitrogen as for gas, to cut make hole expanding with exothermic oxidation, gas pressure is cut the oxygen pressure is small.
Each pulse laser only small particles of eruption, deepen gradually, so thick plate perforation moment needs a few seconds.
Once completion of perforation, vertical line for gas with oxygen for open.
This perforation diameter smaller, the perforation quality is better than that of blast hole.
Therefore, the use of laser not only should have high output power, more important is time and space characteristics of beam;
In addition also need to have a strong pneumatic control system, with complete varieties, gas pressure switch and perforation moment control.

Explosive perforation 】

After laser shines in a row that constitute a pit in the middle, and the oxygen flow with coaxial laser beam will soon be molten material removed form a hole.
Usually hole intrusive related to thickness, blast hole even half of diameter to thickness, so for the thicker plate explosive perforation aperture is bigger, and do not round, should not be used on parts machining precision demand is higher, can only be used for waste.
In addition because of perforation used oxygen pressure and cut, splash is bigger.
2.
Laser plate cutting machine processing stainless steel and coated aluminium zinc plate, the workpiece is burr
appear this kind of circumstance, the first thing to think elements to present burr cut mild steel, but not cut briefly accelerating speed, because of the added speed sometimes present board cut don't wear condition, this kind of condition in processing when apply the aluminum zinc plate is particularly prominent.
At this time should be resolved thinking the other elements of iron plate cutting machine, such as whether to replace the nozzle, guide rail movement is not stable, etc.
3.
Laser plate cutting machine cutting processing hole deformation status of
this is due to the machine tool in processing without the adoption of blast hole method, but with the pulse perforation method, makes the laser energy is too focused on a small area, will not processing areas also burned, led to the deformation of the hole, affects the processing quality.
At this time, should be in process lieutenant general pulse perforation method to blast hole method.
The iron plate cutting machine for low power, on the contrary, should adopt the method of pulse perforation when holes machining to achieve better surface finish.
this kind of condition can affect parts of the incision and section finish machining quality.
At the moment in the case of other parameters is normal, should think about the following questions: laser nozzle loss, shall promptly replace the nozzle.
In the absence of new replacement under the condition of the nozzle, should cut operating gas pressure increased;
At nozzle with laser connecting thread is loose.
This moment should be cut immediately suspend, check the laser join condition, from the beginning for thread.
5.
Laser cutting low carbon steel plate cutting machine, the workpiece to present the reason of burr
according to the operation and planning principle of iron plate cutting machine, it is concluded that the following reason is the leading cause of burr formation processing parts occurred: fluctuation of laser focus position is not correct, do focus bearing test requirements, on the basis of the focus offset adjustment;
Not the output power of laser, needs to check the laser generator operation is normal, if it is normal, then investigate laser control button on the output value is correct, then try to adjust;
Cut the linear speed too slow, needs to increase the linear velocity when operating control;
Not cut gas purity, cut demand supply high quality homework gas;
Laser focus shifts, bearing test needs focus, on the basis of the focus offset adjustment;
Time is too long to present machine's operation instability, needs to turn it off from the start at the moment.
6.
The status of the laser plate cutting machine has not completely cut through
analysis can find the following several conditions before and after the processing of unstable primary condition: laser nozzle selection and processing of thickness does not match;
Laser cutting speed too fast, need operation control reduce the linear velocity;
Muzzle induction banning lead to laser focus position error is too big, must have a beginning testing nozzle sensor data, especially the most simple present when cutting aluminum.
China laser equipment factory professional laser equipment manufacturers, products include optical fiber laser cutting machine, laser engraving machine, laser marking machine, etc.
