How to purchase high-quality CNC plasma cutting machine?
When purchasing a plasma cutting machine, how to choose and purchase it is a key problem, because the plasma cutting machine is not a particularly cheap machine. If it is not properly selected and purchased, it may cause a lot of trouble for the later use, so it is very important to determine the speed of setting up the numerical control plasma cutting machine.
At present, the cutting speed of CNC plasma cutting machine is generally determined by the size of plasma power supply, including the thickness of the workpiece to be cut, the adjustment of air pressure, including the system operation during cutting, etc; According to some information learned by relevant industries in recent years, Shaanxi Weinan CNC can be summarized into the following factors for the reference of users:
(1) The model of the plasma cutting machine. This model is generally the output current of the plasma cutting machine, such as 40A, 60A, 100A, 200A, etc. (of course, some models of imported plasma, such as German Kelbe, American Pegasus and other brands are not based on the output current size, which will not be detailed here). According to the power of the model, the selected cutting current size is different, and the cutting speed is also different, The above data you gave did not explain what brand and model of plasma cutting machine you chose, so you could not give detailed data;
(2) The material of plasma cutting workpiece is different, and the cutting speed is also different according to different cutting materials. Common cutting materials: carbon steel and stainless steel cut faster, cast iron slightly slower, followed by aluminum, and zui slow is copper. Because copper and aluminum are difficult to cut, the cutting speed is much slower than the first two, and the cutting thickness of plasma cutting copper and aluminum with the same power is much smaller than that of stainless steel and carbon steel.
(3) The size of the input voltage at the plasma cutting site is generally AC 380V. However, due to the different conditions at each factory site, the general voltage fluctuates between 365V and 410V (of course, there is even greater difference in some places), so the input voltage is also a factor affecting the cutting speed.
