Stainless steel laser cutting machine cutting material is how to return a responsibility?

Stainless steel laser cutting machine cutting materials is how to return a responsibility? In the use of stainless steel laser cutting machine, the workers always encounter such problems encountered in which most is cut material unceasingly, lets workers feel anxious very much. Generally appear this problem, the laser cutting machine pressure is not adjusted, the following small series will take you to understand the stainless steel laser cutting machine!
Laser cutting machine in the process of laser cutting, the gas pressure of the auxiliary gas has a great impact on the results of cutting. The auxiliary gas must have enough pressure in order to completely clear cutting waste slag, generally in the cutting thickness of the workpiece when the pressure to reduce a little, stick to the workpiece on the residue will destroy the cutting edge.
Increase the gas pressure can be cut in advance, but after reaching a maximum value, continue to increase the gas pressure will cause the decline of the cutting speed. Under the pressure of high gas assisted laser cutting machine cutting speed is reduced in addition to can be attributed to the high velocity of and enhance the role of district cooling effect of hanging outside, may also is the interference of laser cooling zone of the airflow in the presence of intermittent pulse waves. The pressure and temperature in the air flow can cause the change of the density of the air flow field. Such a density gradient leads to a change in the refractive index of the field so that the energy of the beam is focused, resulting in re focusing or beam divergence. This interference will affect the efficiency of melting, and sometimes may change the structure of the model, resulting in cutting quality decreased if the beam divergence practiced extortion. So that the spot is too large, and even cause the serious consequences can not be effectively cut.
We when using optical fiber laser cutting machine and want to cut of the product and the most accurate, then we must to first understand what affects the precision cutting, next, we will give you a brief introduction:
The laser beam is tapered, so cut out of the gap is also tapered, in this case, the thickness of the 0.4MM stainless steel will be much smaller than the 3MM. Therefore, the shape of the laser beam depends on a major factor affecting the cutting accuracy of the metal laser cutting machine. Under the condition of the conical laser beam, the greater the thickness of the workpiece, the lower the accuracy, the larger the cut.
Table accuracy, if the accuracy of the table or other reasons will lead to high accuracy of laser cutting effect.
When a tapered laser beam gathered together, at this time will be getting smaller and smaller, so the precision of the laser cutting has become increasingly high, especially cutting seam width becomes smaller and smaller. At this time the smallest spot can reach 0.01mm. This is also one of the factors that affect the cutting accuracy of laser cutting machine.
In this case, the cutting accuracy of different materials is slightly different. Even if the same material, if the composition of the material is different, there will be differences in the accuracy of cutting. Therefore, the workpiece material has a certain influence on the laser cutting precision.
Above is the stainless steel laser cutting machine cutting material reasons, in a stainless steel laser cutting machine cutting things, we must grasp the air pressure, the pressure is too large, too small are prone to cutting problems.
