With the expansion of market demand, more and more customers are beginning to seek a way to increase production efficiency while saving costs. CNC cutting machine is undoubtedly the best choice in sheet blanking.
Many customers are asking CNC cutting machine, will ask the flame cutting machine and plasma cutting machine cost that is cheap? Answer the relevant questions raised by customers today for this issue. I hope to help people who buy cutting machines.
Numerical control cutting machine flame cutting machine and plasma cutting machine analysis and comparison. (The data is for reference only, the specific price should increase or decrease with market fluctuations)
First of all, to understand the scope of application of CNC flame cutting machine, CNC flame cutting machine is mainly used for cutting ordinary carbon steel sheet 6mm-180mm thickness of the workpiece. The thermal deformation of workpieces with a thickness of 0.1mm to 5mm is quite severe. Therefore, at this time, it is necessary to consider purchasing a CNC cutting machine equipped with a 60 amp machine plasma power supply, and then the CNC plasma cutting machine. Cutting range: CNC plasma cutting machine can be used for non-ferrous metals (such as stainless steel, copper, aluminum, etc.) that can not be cut by ordinary carbon steel plates and flame cutting machines, mainly because flame cutting can not oxidize the surface of non-ferrous metals and cannot complete cutting. The plasma is not obvious when the sheet is cut (eg workpieces below 5mm). Therefore, the thicker the workpiece is, the larger the groove is, according to the matching of the plasma power supply (domestic plasma power supply and imported plasma power supply The difference is that there are differences between ordinary plasma power supplies and fine plasma power supplies, and slags and burrs are not the same.
Then talk about the scope of application of CNC flame cutting machine and plasma CNC cutting machine, let's talk about the cost of CNC flame cutting machine and plasma CNC cutting machine in the specific use process:
First, flame cutting:
It is better to cut medium-thickness steel plates, and there is no V-shaped groove on the cut edge, and the maximum can be cut about 200mm, but the deformation of the steel plate below 5mm is larger.
Cost: A bottle of acetylene every 8 hours and a bottle of oxygen for 2 hours. Acetylene 78 yuan / bottle, oxygen 16 yuan / bottle.
8 hours work cost: 78 yuan * 1 bottle + 16 yuan * 4 bottles = 142 yuan II, plasma cutting:
Although plasma power manufacturers claim that they can cut to 100mm, in actual cutting, more than 10mm is more difficult. Cutting below 20mm is particularly advantageous, fast, and small deformation. When the plasma is cutting the thick plate, the cut has a V-shaped groove. But for stainless steel, aluminum, copper and other non-ferrous metals, flame cutting can not!
Cost: Take 6KW power supply as an example, cut the board below 20mm, cost 6KW electricity per hour, 48KW per shift, to 1.00 yuan/kWh, electricity 48 yuan. Electrodes, nozzles are about 15 yuan per set (domestic) and can work for about 3 hours.
8 hours working cost: 48KW * 1 yuan / KW + 15 yuan * 2.6 = 48 yuan + 39 yuan = 87 yuan.
So? The initial investment of the flame CNC cutting machine is small, and the cost of the later stage is high. The plasma CNC cutting machine is not the same as the plasma power source for the previous purchase of the machine, and the price is not the same, but the overall investment is larger than the flame cutting, but the cost is small in the later period. Of course, the specific and the operator's cutting experience has a great relationship.
