From the cutting principle, cutting nozzle is a very important part of getting a high-precision cutting surface by flame cutting. And the correctness of the operation largely will determine the final cutting effect. Meanwhile, the cutting nozzle of a CNC flame cutting machine is one of the most easily damaged parts. Therefore, we should do the proper cleaning and maintenance for the cutting nozzle, which not only can improve the working efficiency of the CNC cutting machine, and guarantee the cutting quality, but also will extend the service life of the CNC flame cutting machine. So as to reduce production cost. The followings are 3 operating suggestions of the CNC flame cutting machine nozzle:

 

Suggestion one: Regularly dredge the CNC flame cutting machine cutting nozzle to prevent clogging

During the cutting process of the CNC flame cutting machine, the high heat splashing slag will be easy to plug the cutting nozzle, so the cutting nozzle cleaning and maintenance is very important. When cleaning the cutting nozzle, you must close the preheating oxygen hand valve, press the oxygen cutting button, open the oxygen cutting solenoid valve and close the cutting valve on the cutting torch to let the cutting nozzle needle insert. In order to blow off the dust, you should get the needle moving up and down for times through oxygen hole, and slowly open the oxygen cutting torch hand valve.

 

Suggestion two: CNC flame cutting machine cutting nozzle selection

Select the appropriate type of CNC flame cutting machine cutting nozzle model. Cutting nozzle model selection should take into consideration the use of gas and cutting materials and thickness.

 

Suggestion three: Cutting nozzle height control of CNC flame cutting machine

Set the proper distance between the CNC flame cutting machine cutting nozzle and the machining parts. When the top of the primary flame (the core of the flame) is about 1 mm above the workpiece, it is the ideal cutting nozzle distance. If the CNC flame cutting machine is not automatically adjusted, the operator should always pay attention to the distance. Also you need to adjust the cutting nozzle height according to the cutting gas. For example, you use the acetylene, it should be from 3 to 10mm, while with other gas from 6 to 12mm. at the same time, if the steel plate deformed or is uneven, you also should adjust. When propane or natural gas is used as fuel gas, the cutting thickness up to 50mm, the cutting nozzle height should be doubled.
