In recent years, we have seen the rapid development of science and technology in our great motherland. This made me feel extremely proud for me as a Chinese. With the advancement of technology and the progress of people, we will join the Chinese cutting machine trading network to make progress together. Join the hotline, we look forward to your call.

The cutting nozzle is a wearing part of the cutting torch of the CNC cutting machine. It is a normal condition that the replacement is worn out during use. However, many users have different degrees in their use to reflect the high frequency of replacement of the cutting tip and serious losses. The following is a summary of the experience for reference:
The electrode cutting nozzle used in the CNC plasma cutting machine is required to pay attention to the cutting nozzle product quality at the time of purchase. Since the cutting nozzle loss is more frequent than the flame cutting when using plasma cutting, the quality of the cutting nozzle purchased by many users is not good, and the use is exacerbated. Cutting nozzle loss during the process requires special attention. It is not possible to choose a poor-quality electrode cutting nozzle simply to save costs. Under normal circumstances, the service life of a set of electrode cutting nozzles varies from 3-4 hours, which is reflected by current users. The problem of too much loss is caused by the following reasons:
1, in addition to taking into account the quality of the electrode nozzle, the purchase of the electrode nozzle and the torch with the right fit is also a big problem, it may be that you use the electrode nozzle and you originally used is not a manufacturer, or electrode nozzle Unlike the manufacturer of the torch, although the appearance of the size looks similar, but the size of different manufacturers are different standards, most manufacturers of electrode nozzle is imitation of some other old plasma products, CNC cutting machine imitation method Based on real sample mapping, it is inevitable that there will be a certain dimensional error during surveying and mapping. Therefore, each manufacturer's electrode nozzles and other manufacturers' cutting guns may not be able to work well with each other. This can easily cause problems.
2, caused by improper use, such as cutting cutting the nozzle from the plate too close (usually 100A plasma cutting when cutting the distance from the steel plate is generally not less than the size of 3 ~ 8 mm), the external input voltage is too high or unstable.
3, cutting the workpiece material, thickness, and cutting process arrangements and other issues, cutting the material of the workpiece, general plate, stainless steel, cast iron and other materials consumed fewer electrode nozzles, some metal materials consumed more accessories (such as copper, aluminum, etc. ) When cutting a sheet with a thickness of about 10 mm, it is more reasonable to use a nozzle. I wonder if there is a sheet of more than 16 mm. If you often cut more than 16mm of sheet metal, it is more costly nozzle, in addition if you often need to pierce the cutting process in the work, then it will be more than twice the number of nozzles from the edge often arc cutting more than one; so everyone is in the election With CNC flame cutting machine power supply and cutting nozzle, it must be remembered that selecting the appropriate power size (usually plasma cutting thickness as the standard) of the plasma power and the size of the ampere size, diameter corresponding to the nozzle is conducive to the most fully achieve the cutting effect and service life [Unexpectedly, nothing can not be done, change your style from now on.
