The Difference between CNC Flame Cutting Machine and CNC Plasma Cutting Machine

CNC flame cutting machine and CNC plasma cutting machine occupy half of the current domestic CNC cutting machine market, in the hearts of our customers has a very high status. Most of them choose these two cutting machines when they choose a CNC cutting machine. Although both cutting machines are red eyes for customers, the two are actually quite different. Today, let's take a look at the differences between CNC flame cutting machines and CNC plasma cutting machines:
First, the cutting principle is different. This is obvious, as you can see from the name. CNC flame cutting machine is to make the temperature reach or exceed the melting point of the cutting plate instantly by the natural gas, and then the liquid is separated by the strong gas; the CNC plasma cutting machine releases the power through the current decomposition, and then converts into heat. This is the essential difference between the three.
Second, cutting materials are different. Since CNC flame cutting is through gas combustion, generally ordinary carbon steel plates can be cut; while CNC plasma cutting machines can cut non-ferrous metal plates. This is not possible with flame cutting machines because non-ferrous metals cannot oxidize the surface.
Third, the cutting thickness is different. In general, the best cutting thickness of CNC flame cutting machine is 6-200mm. If the arc is 6mm, then you have to use plasma to cut.
Fourth, cutting accuracy is different. Strictly speaking, flame cutting is a rough cutting, his cutting accuracy is not much smaller than plasma cutting, and the precision of the current fine plasma cutting machine can already be comparable to the precision of laser cutting.
Fifth, cost of construction is different. The cost of the CNC flame cutting machine is lower than that of the CNC plasma cutting machine, but because the latter cutting requires the use of gas, the post-use cost is high; the numerical control plasma cutting machine is the opposite, and the later use and maintenance cost is low, but the previous period requires the purchase of supporting plasma. Power, so the pre-cost is high. In this regard, the two can be described as merits.
