Some common knowledge about CNC pipe cutting machines

　　CNC pipe cutting machineThe manufacturer believes that regardless of which type of plasma is purchased, considering the budget is very important, because if the budget is ignored, even if the expected effect is achieved, exceeding the budget too much may lead to not buying it. Currently, plasma is mainly divided into two categories: domestic and imported. Among them, domestic prices are divided into low, medium, and high specifications, but overall, users should still be able to accept it! The price of imported products is several times, even dozens of times higher than that of domestic products, and consumables like cutting nozzles and electrodes are much more expensive! Generally speaking, the cutting effect of imported plasma is better than that of domestic plasma of the same specification. Its disadvantage is that the price and subsequent usage costs are too high, which is generally difficult for enterprises to accept!

　　The manufacturer of CNC pipe cutting machines believes that regardless of the type of plasma, there is a suitable cutting size range. It is well known that low-power plasma is suitable for cutting thin plates. If the plasma power is too high, it is not suitable for cutting thin plates! Currently, domestic steel plates below 2mm generally use domestic 40-60A plasma cutting, and occasionally imported steel plates are also used, but the quantity is not large because the price is relatively expensive.

      For steel plates below 2MM, it is important to remember that except for high-speed desktop special thin plate plasma cutting machines, other models such as portable and gantry types are not suitable for cutting. If it exceeds 2mm, it is not limited to this, and it can also be used. Thick steel plates, such as 2-16mm steel plates, can be cut by portable and gantry models, while thicker plates, such as 25mm plates or even thicker plates, are only suitable for gantry models!CNC pipe cutting machineThe manufacturer believes that plasma cutting of stainless steel and other alloy materials is its advantage, while carbon steel plates mainly rely on flame cutting. Therefore, as long as stainless steel is acceptable, a plasma cutting machine must be chosen! Otherwise, processing cannot be achieved with flame!

　　The manufacturer of CNC pipe cutting machines believes that the advantages of CNC plasma cutting machines are:

　　1. Better cutting quality

　　The manufacturer of CNC pipe cutting machines believes that slag, heat-affected zone, top round corners, and cutting angles are the main factors affecting cutting quality. Especially in terms of slag and heat-affected zone, plasma cutting is far superior to flame cutting. Plasma cutting edges basically do not leave slag, and the heat-affected zone is also much smaller.

　　2. Slag

　　The manufacturer of CNC pipe cutting machines believes that plasma technology uses high-temperature charged gas to melt metal and blows the molten metal material away from the cutting surface. Flame cutting uses the chemical reaction between oxygen and steel for cutting, resulting in iron red slag or dross. Due to this technical difference, plasma cutting produces less slag, and the attached slag is easier to remove. These slags can usually be easily knocked off without grinding or removal, greatly reducing the time required for secondary processing. Fewer grinding operations lead to higher productivity.

　　3. Heat-affected zone

　　CNC pipe cutting machineThe manufacturer believes that one issue to pay attention to when cutting metal is the size of the heat-affected zone. High temperatures can change the chemical structure of the metal, causing the heated edges to turn black (tempering color) and warp. If the heated edges are not removed, the workpiece may not be suitable for secondary welding. Regardless of the process used, the faster the cutting torch moves, the smaller the heat-affected zone. The rapid cutting characteristics of plasma make the generated heat-affected zone smaller, thus shortening the time spent on cleaning the heated edges in secondary processing. Some flame cutting users may also pay attention to the color blending. The heat-affected zone cannot be seen from the outside, but the tempering color, which is not visible, can cause discoloration of the metal. Similarly, the rapid cutting of plasma reduces the area of the tempering color.
