Plasma cutting machine application field for the traditional gas cutting processing method of the biggest advantage is to make up for the use of non-carbon steel materials, from the current domestic plasma cutting machine application technology, for stainless steel and other high hardness materials cutting processing is still mainly adopt plasma cutting, This also greatly promoted the rapid development and market popularity of plasma cutting machine equipment in China in recent years. This paper is edited by the technology department of Wuhan Jiabide Technology Co., LTD. It mainly explains the design requirements of processing parameters and use specifications of stainless steel plasma cutting machine.
CNC plasma cutting machine in the processing of stainless steel materials, several important cutting configuration parameters for the cutting speed and the size of the input current, in general, we suggest that the user according to the manufacturer provided equipment parameter configuration table adjustment related parameters design to achieve the best cutting quality effect; However, in the actual production process, it may be necessary to adjust the above parameters due to the transfer of production efficiency or processing quality. To this end, Wuhan Jiabide technology will be from the CNC plasma cutting machine input current and the adjustment of the cutting speed for you in-depth analysis.
One, stainless steel plasma cutting machine cutting speed
1. The best cutting speed range can be selected according to the equipment instructions or determined by test, due to the thickness of the material, different materials, melting point, thermal conductivity and surface tension after melting and other factors, cutting speed is also the corresponding change. Main performance:
2. When the cutting speed is too low, due to the anode is the plasma arc cutting, in order to maintain the stability of the arc itself and the anode spots or anode area must near the nearest arc cutting seam find conduction current place, at the same time to the jet of radial transfer more heat and thus make the incision width and incision on both sides of the molten material in bottom flange and solidification, The hanging slag is not easy to clean, and the upper edge of the incision is rounded because of too much melting.
3. When the speed is very low, the arc will even be extinguished due to the wide cut. Thus, good cutting quality and cutting speed is inseparable.
4. Cutting speed can improve the quality of the incision, that is, the incision is slightly narrower, the incision surface is more smooth, and the deformation can be reduced.
5. The cutting speed is too fast to make the cutting line energy lower than the required value, the jet in the cutting seam can not quickly blow off the molten cutting melt immediately and form a large drag, accompanied by the cutting slag, the cutting surface quality decreases.
Two, stainless steel plasma cutting machine cutting current
It is the most important cutting parameters of CNC plasma cutting machine, which directly determines the thickness and speed of cutting, that is, cutting capacity. Make an impact:
1. Cutting current increases, arc energy increases, cutting ability improves, cutting speed is increased;
2. The cutting current is too large to increase the heat load of the nozzle, the nozzle is prematurely damaged, the cutting quality naturally decreases, and even can not be cut normally. Therefore, the cutting current and the corresponding nozzle should be selected correctly according to the thickness of the material before cutting.
3. Cutting current increases, arc diameter increases, arc coarsening makes the incision wider.O
