When the CNC plasma cutting machine adopts the electric cutting work, the control of the cutting current is the key factor to realize the precision cutting and general electric cutting. Here we can also understand that the cutting efficiency and the numerical control
The plasma cutting machine equipment itself has no direct relationship, because the plasma cutting process has determined the accuracy error range of the workpiece, which causes the large deviation of the accuracy of the materials processed by different operators.
There are small, the key lies in the differences in some core parameters and operating skills, Xunfeng series flame or plasma cutting machines, after years of experience and tempering, also have high efficiency. CNC flame cutting
Or plasma cutting, because the width of the cutting mouth is affected by various factors such as the cutting nozzle, no matter how high the precision of the equipment itself is, the precision of the parts cut by it is generally about ±0.5mm.
Several orders of magnitude higher than the device itself.
Plasma cutting has different requirements for the accuracy of workpieces than general manual operations. From the processing characteristics of CNC plasma cutting machines, the accuracy of the parts cut by it, the error is generally ±0.5mm
However, many user companies fail to meet the above standards in the actual operation process; and from the perspective of production efficiency, the cutting speed, taking flame cutting as an example, depends entirely on the thickness of the sheet and the type of cutting nozzle.
No., oxygen purity, gas quality and other factors, the moving speed of the equipment should meet and adapt to the requirements of the cutting process. When the CNC plasma cutting machine cuts the workpiece, the cutting current of the machine plasma power supply
It is the most important cutting process parameter that directly determines the thickness and speed of the cutting, that is, the cutting ability. Regarding the impact, it is directly reflected in the following points of CNC plasma cutting
The selection form of the cutting current of the machine:
1. The increase of the cutting current of the CNC plasma cutting machine, the increase of the plasma arc energy, the improvement of the cutting ability, and the increase of the cutting speed;
2. The cutting current of the CNC plasma cutting machine increases, the diameter of the plasma arc increases, and the arc becomes thicker and the incision becomes wider;
3. The excessive cutting current of the CNC plasma cutting machine increases the thermal load of the nozzle, the nozzle is damaged prematurely, and the cutting quality naturally declines, and even normal cutting cannot be performed. So before cutting, according to
The thickness of the material is the correct selection of the cutting current and the corresponding nozzle.
