CNC flame cutting machine flame cutting nozzle maintenance tips?

1.Select the appropriate type of flame cutting nozzle. The choice of cutting nozzle model needs to be comprehensively considered according to the gas used, cutting material and thickness. The structure of propane cutting nozzle and acetylene cutting nozzle is different, and it is not suitable for general use. Therefore, choosing the right cutting nozzle will get twice the result with half the effort in production .

2. Calibrate the proper distance between the flame cutting nozzle and the workpiece. If the CNC flame cutting machine is not equipped with a capacitor to automatically adjust the height, the operator should always pay attention to the appropriate distance between the cutting nozzle and the workpiece. When the primary flame (the flame core of the flame) is about 1 mm above the workpiece, it is the ideal spacing of the cutting nozzles. In addition, it is necessary to adjust the height of the cutting nozzle appropriately according to the use of cutting gas, such as 3-10mm when using acetylene, and 6-12mm when using other gas. On the other hand, if the steel plate is deformed or uneven, it should be adjusted. When using propane or natural gas as fuel gas, when the cutting thickness reaches 50mm, the height of the cutting nozzle should be doubled.

3. Pay attention to the cleaning and maintenance of the cutting nozzle. The cutting nozzle is also one of the easily damaged consumables in the CNC cutting machine parts. Therefore, proper cleaning and maintenance of the CNC cutting nozzle can not only improve the working efficiency of the CNC cutting machine, ensure its cutting quality, but also prolong the service life of the CNC cutting machine. Thereby reducing production costs.

4. Regularly clear the cutting nozzle to prevent blockage. During the cutting process, the molten slag splashed under high heat can easily block the cutting nozzle, so the cleaning and maintenance of the cutting nozzle is very important. When cleaning the cutting nozzle, close the preheating oxygen hand valve; press the cutting oxygen button to open the cutting oxygen solenoid valve; close the cutting hand valve on the cutting torch, so that the cutting nozzle can be inserted through the needle. Twitch up and down the fast oxygen hole, and slowly open the torch to cut the oxygen hand valve. In order to facilitate the use of users and enterprises, each set of equipment will be delivered with a set of needles, which users can keep for future use.
