Analysis of the cutting speed of laser cutting equipment

At present, with the rapid development of laser cutting technology, a variety of high-performance products emerge in endlessly, which quickly occupy the attention of users. In this situation of rapid development, users should learn to calm down and observe carefully,

Choose the right equipment carefully. How to choose the right equipment from the complex information? This is also the problem that Kunshan Joule laser has been trying to solve for you. Today, Kunshan Joule laser is going to talk about the significance of cutting speed for laser cutting equipment. The cutting speed of laser cutting equipment has always been a topic of concern for many processing enterprises. Below, Kunshan jour laser will explain the factors that affect the cutting speed of laser cutting equipment, the influence of the cutting speed of laser cutting equipment on the cutting quality, and how to improve the cutting speed of laser cutting equipment.

1、 What factors are related to the cutting speed of laser cutting equipment?

For the given laser power density and material, the cutting speed is generally in line with an empirical formula. As long as it is within the threshold, the cutting speed of the material is basically proportional to the laser power density, that is, increasing the power density can improve the cutting speed; And according to the normal situation, the cutting speed is inversely proportional to the density and thickness of the material to be cut.

PS: the power density is not only related to the laser output power, but also to the beam quality mode. In addition, the characteristics of the beam focusing system, that is, the size of the focused spot also has a great influence on the cutting speed.

2、 What is the influence of laser cutting speed on cutting quality?

When the cutting speed is too low, because the cutting place is the anode of the plasma arc, in order to maintain the stability of the arc itself, the anode spot or anode area must find the conductive current place near the nearest slit to the arc, and at the same time, it will transfer more heat to the jet radially, so that the notch becomes wider, and the molten materials on both sides of the notch gather and solidify at the bottom edge, Moreover, the upper edge of the incision is easy to form fillet due to excessive heating and melting. If the cutting speed is properly increased, the quality of the incision can be improved, that is, the incision is slightly narrower, the surface of the incision is smoother, and the deformation can be reduced. Once the cutting speed is too fast, the linear energy of cutting will be lower than the required value. The jet in the cutting seam can not quickly blow off the molten cutting melt, thus forming a large amount of drag, accompanied by the problems of slag hanging on the incision and the decline of the surface quality of the incision.

3、 How to improve the cutting speed of laser cutting equipment

Increase the power in a certain range; Improve the beam mode; Reduce the focus spot size (e.g. focus with short focal length lens).
