The famous American quality management scientist said that the 20th century is the century of productivity, the 21st century is the century of quality, and quality is the most effective weapon for occupying the market peacefully. The industry of cutting machines is very useful in such evaluations. Details:/
What are the plasma power overload phenomena? How to solve the gantry cutting machine plasma power overload?
Under normal circumstances, the plasma power overload is mainly manifested in the following two aspects, the thickness of the cut exceeds the power and cutting nozzles.
The cutting current of the plasma cutting machine increases, the diameter of the plasma arc increases, and the thickening of the arc makes the incision widen. When purchasing a gantry type CNC cutting machine, the manufacturer will recommend the appropriate plasma power supply and cutting nozzle model according to the processing needs of the company. This is not only to reduce the cost of procurement, but more importantly to optimize the cutting results.
In general, the gantry type CNC cutting machine can not pierce the steel plate beyond its working thickness. The usual perforation thickness is 1/2 of the normal cutting thickness. For example, if the 100A plasma system is set to cut 1 inch of carbon steel, then the The perforation thickness of the system should be 0.5 inches.
With the increase of the cutting current of the plasma cutting machine, the energy of the plasma arc increases, the cutting ability advances, and the cutting speed increases. Gantry type CNC plasma cutting machine in the actual cutting process, because of the improper use of plasma power supply and consumables accessories, often throwing plasma power overload, resulting in extreme consumption of supplies and accessories, improved production costs. However, after purchasing a gantry cutting machine, many companies cut the thickness of the material beyond the acceptable range of the power supply and the cutting nozzle due to business adjustments or manipulation inadvertently. This will have a great impact on the electrode torch and plasma power supply. In general, the current intensity should be 95% of the nozzle operating current.
The influence of the current selection of the gantry plasma cutting machine on the cutting ability:
When the plasma CNC cutting machine cuts the workpiece, the cutting current adjustment problem of the machine plasma power supply is very important. It is the most important cutting process parameter, and directly determines the thickness and speed of the cutting, ie the cutting ability. Therefore, the plasma CNC cutting machine can only work better by selecting an accurate current. How to choose the correct CNC plasma cutting machine current?
The influence of the cutting process parameters on the cutting ability and the effect is more directly expressed in the cutting current selection mode of the plasma cutting machine:
If the cutting current of the CNC plasma cutting machine is too large, the thermal load of the nozzle increases, the nozzle is damaged prematurely, the cutting quality naturally decreases, and even normal cutting cannot be performed. Therefore, the cutting current and the corresponding cutting current must be accurately selected according to the thickness of the material. nozzle. .
Electrode nozzles are overloaded. When many companies use CNC flame cutting machines, they like to increase the current intensity of the power supply to the right. Even if the thickness of the cutting material does not reach the upper limit of plasma power cutting, but in order to improve the cutting speed and efficiency, it is still Working at 100% current, this overloads the electrode nozzle and can cause the nozzle to break down quickly.
