Solve the problem of tempering of portable CNC cutting machine

<


With CNC technology, the efficiency of the cutting machine is improved and it has higher accuracy. With portable CNC cutting machine is further improved on the basis of numerical control cutting machine on the performance characteristics, it has a smaller size and portability. CNC cutting machine is the application of numerical control technology in the field of cutting machine. This design is a great change of cutting machine, which makes the performance of cutting machine greatly improved.

The phenomenon of tempering mainly means that when the cutting is performed, the flame of the gas is not sprayed to the outside, but is returned to the inside of the nozzle for reverse combustion. The tempering phenomenon in portable CNC cutting machines that we are talking about is actually quite common. What are the main reasons for this phenomenon ?

When cutting with a portable CNC cutting machine, if the cutting time is too long, or the distance of the weldment is too small during cutting, the temperature inside the cutting nozzle will be high. The increase in temperature causes the pressure to become larger, which affects the flow of gas inside, which also causes tempering.

There is a further reason is that, when the gas discharge has not been time to outside combustion gases has been finished, the flame will burn at this time inside the nozzle. The main reason is that the gas goes out faster than the burning speed.



At the time of cutting, if the inside of the cutting nozzle or the inside of the pipe for conveying gas is stained with other easily combustible substances, it may also be some carbon-containing particles, which may cause tempering at this time. In the cutting process, maintenance equipment is the most important, not only affecting the quality of the cutting but also reducing the service life of the equipment.
