Two kinds of perforated metal cutting machine technology how to choose

Before cutting machine start cutting need to make a hole, then to the hole as a starting point for cutting. Cutting machine punch in one of two ways:





perforation caused by blasting is a kind of technology, through a continuous light, make the surface to form a groove, and then using the cutting beam, can quickly melt material, to complete the punch. This case will not be able to guarantee the quality of the perforation aperture size is about half the thickness of the plate, and as a result of the quality of the plate, also not the same, the quality of this punch is not smooth, sometimes affect the quality of the workpiece, in addition, the perforation technology USES is the method of oxygen blowing, blowing pressure perforation need is larger, it is easy to appear the situation of the slag splashing.

the other is a common method of pulse cut perforation, this method is to use a peak value method of cutting power, let a small amount of material melt or boil, using nitrogen as auxiliary gas, reduce oxidation reaction in the air, and this method is compared with a feature of this method is the less pressure of the gas, producing many of slag granules is given priority to, there will be no hang slag, and has little effect on the thickness of the plate for this kind of method, that is to say how thick board can do.

overall, pulse cutting punch method is higher than the accuracy of the blasting cutting, suitable for precision processing.
