CNC flame cutting machine in use, in addition to the requirements of the hardware and equipment, the common parts and accessories of the quality and stability of the need to have a certain understanding of cutting the nozzle as a CNC flame cutting machine is a key component, usually Used in the processing process, the operator's failure and its handling methods have a better grasp.
      1, the nozzle and cut the flame, after a rigorous processing, although the fire flame normal, but open the cut oxygen valve, the flame immediately extinguished. The reason is cutting the mouth and the torch, a look is not strict. This should be cut mouth tightened, ineffective remove the cut mouth, with fine sandpaper gently. Cut the nozzle with a surface finish until it is close to the surface.
      2, to keep the cutting mouth channel cleaning incision channel should be kept clean, dirt within the pores should be removed at any time with a needle.
      3, the flame is extinguished after the ignition, when the screw preheat oxygen valve to adjust the flame. If the flame is extinguished immediately. The reason is that the memory of the gas channel is dirt or the tube is not in contact with the horn, and the incision sleeve and the mouth are inappropriate. At this point, the injection pipe nut; invalid, should remove the fuel injection pipe, dirt and adjust the gas channel in the clear cover and the inner sleeve gap and fastening.
      4, select the appropriate incision should be based on the thickness of the workpiece, select the appropriate incision. When the cutting nozzle is assembled, the inner and outer nozzles must be kept concentric to ensure that the cutting oxygen jet is located at the center of the preheat flame.
