1. Plasma CNC cutting machine can improve the quality of incision when the cutting speed is properly improved, that is, the incision is slightly narrowed, the incision surface is more even, and the deformation can be reduced at the same time.
2. When the cutting speed is too fast, the plasma CNC cutting machine makes the cutting line energy lower than the required value. The jet in the cutting seam cannot quickly blow the melted cutting melt off immediately to form a large rear dragging volume. With the slag on the cut, the surface quality of the cut is reduced.
3. When the cutting speed of the plasma CNC cutting machine is too low, because the cutting point 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 conduction current place near the nearest kerf of the arc. At the same time, more heat is transmitted to the radial direction of the jet, so that the incision is widened. The material melted on both sides of the incision gathers and solidifies at the bottom edge to form a dregs that is difficult to be cleaned, and the upper edge of the incision is formed due to excessive heating and melting. Rounded corners.
4. When the cutting speed of plasma CNC cutting machine is extremely low, the arc will even extinguish due to the wide incision. Thus, good cutting quality and cutting speed are inseparable.
The above is about plasma cutting machine speed adjustment and control of a number of questions to answer, if any are not correct, please correct me, focus on communication.
How to improve the efficiency of plasma cutting machine
Usually the best cutting speed range of plasma cutting machine can be selected according to the equipment instructions or determined by experiments, but due to the thickness of the workpiece to be cut, the material is different (such as copper, stainless steel, galvanized sheet, aluminum, carbon steel, etc. And non-ferrous metals), melting point, thermal conductivity and surface tension after melting and other factors, so the plasma cutting speed of the CNC cutting machine has a corresponding change. Its main performance is the following:
