Several factors affecting the cutting speed of CNC plasma cutting machine:

1. The material of the cutting workpiece, different materials have different cutting speeds. Common cutting materials: carbon steel, stainless steel, cutting speed is faster, cast iron is slower, followed by aluminum, the slowest is copper;

2. The matching situation of the power supply of CNC plasma cutting machine. At present, there are many types of plasma power supply. According to the output current of cnc plasma cutting machine, there are 40A, 60A, 100A, 200A, etc .;

3.The size of the input voltage at the cutting site. Generally, the cnc plasma cutting machine power supply voltage of the factory is AC 380V.

However, due to the different conditions on the factory site, the general voltage fluctuates between 365V and 410V, so the input voltage also affects the cutting efficiency An important factor.
