When using a laser cutting machine to process materials, the cutting speed and cutting effect of the laser cutting machine are two issues that everyone is more concerned about. So what is the relationship between the cutting speed of the laser cutting machine and the cutting effect of the material? Let's take a look. The choice of the cutting speed of the laser cutting machine during cutting is actually very important. The best cutting speed range can be selected according to the equipment description or determined by experiments. Due to the thickness of the material, the difference in the material, the melting point, the thermal conductivity and the melting After the surface tension and other factors, the cutting speed also changes accordingly. The specific links are as follows:    1. A moderate increase in the cutting speed can improve the quality of the incision, that is, the incision is slightly narrower, the surface of the incision is flatter, and deformation can be reduced. 2. The cutting speed is too fast, so that the cutting line energy is lower than the required value. The jet in the cutting seam cannot quickly blow off the melted cutting melt immediately and form a large amount of back drag, accompanied by cutting slag and cutting. The surface quality is degraded. 3. When the cutting speed is too low, because the cutting location 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 a place to conduct current near the slit closest to the arc, and it will flow to the jet at the same time. More heat is transferred in the radial direction, so that the incision becomes wider. The molten material on both sides of the incision gathers and solidifies at the bottom edge, forming dross that is not easy to clean, and the upper edge of the incision becomes rounded due to excessive heating and melting.  4. When the speed is extremely low, the arc may even go out due to the wide cut. It can be seen that good cutting quality and cutting speed are inseparable.
