The flame debugging of CNC flame cutting machine should be divided into two steps in detail, namely fire adjustment and fire test. Next, learn the fire adjustment skills of CNC flame cutting machine with REBOUND CNC.

Adjusting the flame is based on the thickness of the cutting material and a general understanding of the temperature of the cutting flame through observation, so as to meet the appropriate temperature requirements; The fire test is the experiment before formal cutting, that is, try to understand the actual effect of cutting through the cutting of small segments.

After purchasing CNC flame cutting machine, many customers have been unable to master the adjustment skills of flame in the process of use, resulting in a lot of material waste and even affecting the use of CNC cutting equipment.

In fact, the CNC flame cutting machine can be solved as long as the supply source of oxygen is adjusted.

In the process of flame NC cutting machine, the purity of oxygen is an important factor affecting the process and quality of gas cutting. Poor oxygen purity not only greatly reduces the cutting speed, rough cutting surface, slag on the lower edge of the incision, but also increases the oxygen consumption. The oxygen purity decreased from 99.5% to 98%, i.e. decreased by 1.5%, the cutting speed decreased by 25%, and the oxygen consumption increased by 50%.

It is generally believed that if the oxygen purity is lower than 95%, gas cutting cannot be carried out. In order to obtain a gas cutting cut without sticking slag, the oxygen purity needs to reach 99.6%. Therefore, for flame CNC cutting machine, the purity of oxygen can not be ignored!

Of course, before the specific implementation of the preliminary flame commissioning of the NC flame cutting machine, in order to ensure the normal operation of the equipment, we should also pay attention to some details:

In order to facilitate the flame adjustment, the fire test function is specially set up. In the main interface state of the system startup, press the "fire test" key, and the system enters the fire test interface. Press the "ignition" key, and the system will automatically turn on the ignition, ignition acetylene, preheating oxygen and gas acetylene. If you need to turn on the cutting oxygen, you can turn on the cutting oxygen switch in the lower right corner of the control panel to adjust the size of the cutting oxygen. Press the "back" key to end the fire test.

Flame adjustment, that is, adjust the valve opening of acetylene and preheated oxygen to debug the flame. At this time, you can also check whether the cutting nozzle is blocked. Generally, the oxygen cutting valve will not be adjusted after the valve is opened to the maximum. During fire test and preheating, the control system of NC flame cutting machine does not automatically turn on the cutting oxygen. If it is necessary to turn on the cutting oxygen, you can manually turn on the cutting oxygen button on the operation panel.

Cutting oxygen: when the machine starts cutting and moving, the valve will open automatically.

Oxygen and acetylene are all opened and closed by computer-controlled gas valves. The corresponding switches on the cutting gun of NC flame cutting machine are only used to adjust the gas volume and the proportion of them. Once adjusted, do not adjust them at will, let alone use them as gas valve switches.

After the system enters automatic cutting, if the preheating time is over and the parts to be cut are not preheated well, the preheating plus time method can also be adopted for preheating delay, and cutting can be carried out after preheating.

In the process of machining, the common methods of plate cutting include manual cutting, semi-automatic cutting machine cutting and NC cutting machine cutting. However, in the process of thick plate metal processing, REBOUND CNC still suggests that users use CNC flame cutting machine for cutting, which can effectively improve the efficiency and quality of plate cutting and reduce the labor intensity of operators.

CNC flame cutting machine is a mechanical equipment mainly suitable for the cutting and processing of medium and heavy plates. Compared with other similar thermal cutting CNC plasma cutting machine and CNC optical fiber laser cutting machine, CNC flame cutting machine has the characteristics of high cutting quality, good perpendicularity of cutting surface and large cutting thickness. It is a kind of cutting and processing method widely used in the domestic market at present.
