Assuming that the user set the numerical control cutting machine gas pressure is too low, then in the operation of the numerical control plasma cutting machine ion arc spewing speed will be reduced, and then the input air flow will be less than the specified value, which will form a high energy, high speed plasma arc, the effect is to form the blockage quality is poor, impenetrable, blockage product tumor phenomenon.Among them, the reasons for the lack of pressure of CNC cutting saw are the lack of air compressor input air, the air dispatching valve pressure regulation is too low, there is oil in the solenoid valve, the air path is not smooth, etc. Here we require the operation of CNC cutting machine personnel before the use of attention to investigate the air compressor output pressure display, such as does not meet the requirements, to adjust in time, so as not to constitute a waste of material and time.

In addition, when the working gas pressure of CNC cutting machine is higher than 0.45MPa, we will judge that the auxiliary pressure is too high, then after the CNC cutting mechanism into ion arc, too much air will blow the arc column will set, so that the arc column energy loose, weaken the plasma arc cutting strength. The causes of high air pressure are: improper input air mediation, air filter reducing valve scheduling is too high or air filter decompression failure. Here we require the operator to check whether the air compressor is adjusted appropriately, and whether the pressure of the air compressor and the air filter reducing valve is out of kilter.After starting, if the air filter reducing valve scheduling switch is rotated, it indicates that there is no change, indicating that the air filter reducing valve is out of order and needs to be replaced. Pressure or repair the air compressor. If the input pressure has met the requirements, it is necessary to check whether the scheduling of the air filter reducing valve is correct and whether the gauge pressure flash can satisfy the cutting requirements. Otherwise, daily protection and maintenance of the air filter reducing valve should be carried out to ensure that the input air is dry and dirty. Assuming that the input air quality is poor, it will constitute oil pollution in the solenoid valve, the spool is difficult to open, and the valve port can not be completely opened. In addition. Cutting moment nozzle pressure is too low, but also need to replace the solenoid valve; The smaller section of the gas path will also constitute too low pressure, and the gas pipe can be replaced according to the instructions.

The common problem in the CNC cutting machine is frequency converter disorder, generally constitute the cutting machine frequency converter disorder there are two reasons: one is the chain of the cutting machine because of long-term use and slack phenomenon, and then lead to the frequency converter to bear excessive output, and then lead to disorder; Second, the saw seat motor of the cutting machine has defects, which can detect the motor to eliminate the defects.Regarding these common problems, if the customer does know well, after the onset of the problem, it is very simple to identify the location of the symptoms according to the defect phenomenon, find out the corresponding treatment method according to the defect, and then quickly restore the normal use of the opening machine.
