The reasons for the decrease of the cutting speed of the laser die cutter

In the process of using the laser die cutter for a long time, there are problems such as slow cutting speed and poor cutting accuracy. Many people think that the power of the laser tube has decreased. There are many reasons that affect the cutting speed of the laser die cutter, not necessarily the laser tube. Now we analyze the reasons that may cause the cutting speed of the laser die-cutting machine to decrease as below.

Cutting speed: The cutting speed has a great influence on the power of the laser die cutter, and the cutting speed is proportional to the power of the laser die cutter. At the same time, the cutting quality is related to the quality of the laser beam, and it is also related to the characteristics of the laser beam focusing system, that is, the size of the laser beam after focusing has a great influence on the laser cutting quality. 

Auxiliary gas: The size and pressure of the auxiliary gas also affect the cutting speed of the laser die cutter. The auxiliary gas uses compressed air or inert gas. If the thickness of the knife template increases or the cutting speed is slow, the gas pressure should be appropriately reduced. Cutting with low air pressure can prevent edge carbonization. 

Focal position: It affects the cutting accuracy, especially the focal spot diameter. The diameter of the focal spot should be as small as possible to generate a narrow slit, and the diameter of the focal spot is proportional to the focal depth of the focusing lens, and the smaller the focal depth of the focusing lens, the smaller the focal spot diameter. 

The distance of the nozzle: the distance between the knife template and the nozzle also affects the cutting speed of the knife die machine. If the distance is too far or too close, it will affect the cutting seam, which will also affect the speed. Plates with different thicknesses correspond to their appropriate focal lengths. In addition, when the laser cutter machine cuts the plates with uneven surfaces, it mainly depends on the follow-up adjustment of the laser head. The height of the nozzle and the processed sheet is always consistent during operation. 

If the first four items are excluded, the power reduction of the laser tube is considered. The laser tube is the core light source of the laser die cutter, and it is also the only material of the laser die die machine (the lens is strictly one of the consumables). Under normal circumstances, the laser die die machine will have a certain degree of The cutting speed decreases, which is due to the weakening of the power of the laser tube, which is normal.

In addition to the above points, the thickness, hardness, density, etc. of the cutting plate will affect the cutting speed of the die cutter.
