When using a portable CNC cutting machine , many people don't know what the best cutting speed is. Let's find out with Xiaobian, the cutting equipment manufacturer
The optimal cutting speed range can be selected according to the equipment description or determined by experiments. Because of the thickness of the material, different materials, high and low melting points, thermal conductivity, and surface tension after melting, the cutting speed changes accordingly. When the cutting speed is too low, because the cutting place is the anode of the plasma arc, in order to maintain the chaos of the arc itself, the anode freckles or the anode area must find a place for conducting current around the slit nearest the arc, and at the same time it will direct More heat is transferred to the incision, so the incision is widened, and the melted material on both sides of the incision will be extracted and solidified at the bottom edge, forming slag that is not easy to clean, and the upper edge of the incision will be rounded due to excessive heating and melting.
It can be seen that good cutting quality and cutting speed are inseparable. When the speed is extremely low, the arc may even extinguish because the cut is too wide.
The main cutting performance of the portable CNC cutting machine mainly manifests: Moderate cutting speed can improve the quality of the cut, that is, the cut is slightly narrower, the cut surface is flatter, and the deformation can be reduced. The cutting speed is too fast to make the line energy of the cutting Below the required value, the jet in the slit cannot quickly blow away the molten cutting melt immediately to form a large back drag. With the dross following the incision, the quality of the incision surface declines. Which CNC cutting machine is better?
