There are many factors that affect the cutting quality of new-type fiber lasers. 1. For example, various plasma arc cutting process parameters such as no-load voltage and arc column voltage, cutting current, electrode shrinkage, and cutting nozzle height will directly affect the cutting process. Stability, cutting quality and effect. In general, factors such as no-load voltage and arc column voltage, cutting current, electrode shrinkage, and cutting tip height directly affect the compression effect of the plasma arc, that is, the temperature and energy density of the plasma arc. High temperature and high energy determine the cutting speed, so it can be said that many of the above factors are essentially related to the cutting speed. As a new type of CNC fiber laser cutting machine equipment, the cutting speed should be increased as much as possible while ensuring the cutting quality. This not only improves productivity, but also reduces the amount of deformation of the part being cut and the heat-affected area of the slit area. If the cutting speed is not appropriate, the effect will be reversed, and the sticky slag will increase, and the cutting quality will decrease.
At present, the new fiber laser cutting is divided into multiple types according to the cutting auxiliary gas. The cutting speed specifications of different auxiliary cutting gases are different. Take air plasma arc cutting as an example. When cutting carbon steel plates, the cutting current is 230A. The cutting speed of 6mm thickness carbon steel plate can reach 3300mm / min is more suitable; when the plate thickness is adjusted to 40mm, the cutting speed is limited to 500mm / min to ensure the cutting effect and quality. If another auxiliary cutting gas is used, such as cutting with pure oxygen, the cutting speed will decrease even more. At the same cutting current of 230A, although the new fiber laser cutting of pure oxygen with 6mm thickness carbon steel plate can be increased to 3700mm / min, but for 40mm carbon The cutting speed of the steel plate is only 350mm / min.
Through the introduction above, you should know how to deal with this situation. In fact, this situation should be very simple for us. We pay attention to the cutting technical parameters and cutting speed of the fiber laser cutting machine during the cutting process. Control, you do n’t have to worry too much.
