As the CNC EPS cutting machine is widely used in the EPS industry, its characteristics and advantages have been recognized by everyone. In order to better use it, let us learn about the methods of controlling the current speed of the CNC EPS cutting machine.

The parameters of the CNC EPS cutting machine has a very important effect on the cutting quality, cutting speed and efficiency. Accurately use a CNC EPS cutting machine for high-quality fast cutting. When the cutting speed is too low, because the cutting site is the anode of the plasma arc, in order to maintain the arc itself, the anode freckles or anode area must be close to the arc. Find a place for conducting current around the slit, and at the same time transfer more heat to the radial direction of the jet, thus making the slit wider, the molten material on both sides of the slit will be extracted and solidified at the bottom edge, forming a slag that is not easy to clean, and the slit The upper edge is rounded due to excessive heating and melting. When the speed is extremely low, the arc may even be extinguished because the incision is too wide. It can be seen that good cutting quality and cutting speed are inseparable.

The cutting speed of the CNC EPS cutting machine is too fast, so that the cutting line energy is lower than the required value, and the jet in the cutting seam cannot quickly blow off the molten cutting melt immediately, forming a large amount of back drag, which is accompanied by the incision. Slag, the quality of the cut surface is reduced. A moderate increase in cutting speed can improve the quality of the cut, that is, the cut is slightly narrower, the surface of the cut is flatter, and the deformation can be reduced. The cutting speed range can be selected according to the equipment description or determined by experiment. Because of the thickness of the material, different materials, high or low melting point, thermal conductivity and surface tension after melting, the cutting speed also changes accordingly. Excessive cutting current increases the thermal load of the nozzle, and the nozzle is damaged prematurely, and the cutting quality is naturally reduced, and even normal cutting cannot be performed. Therefore, before cutting, the cutting current and the corresponding nozzle should be accurately selected according to the thickness of the material. The cutting current increases, the arc diameter increases, and the arc becomes thicker to make the incision wider; the cutting current increases, the arc energy increases, and the cutting ability improves, and the cutting speed increases accordingly; the cutting current is an important cutting process parameter, which directly determines The thickness and speed of the cutting, that is, the cutting capacity.
