People have a common concept, using CNC equipment, you can get high precision, high efficiency. Moreover, in the same type of equipment, the imported, high-end configuration equipment has higher precision and higher production efficiency.
However, CNC flame or plasma cutting machines are not the case at all. Regardless of the numerical control flame cutting or plasma cutting, since the width of the cutting mouth is affected by various factors such as the cutting nozzle, no matter how high the precision of the equipment itself, the accuracy of the parts cut by the cutting, the error is generally about ±0.5mm, The error is several orders of magnitude higher than the device itself. That is to say, or with millions of huge-volume imported CNC cutting machines, this can only be the case.
Cnc Cutting Machine selection ideas
From the above analysis, no matter who produces the CNC Cutting Machine, from the cutting accuracy and production efficiency, there will be no big difference. That is to say, even if the small numerical control is as small as 10,000 yuan, compared with the large numerical control imported by millions, the precision, roughness and production efficiency of the processed parts will not be greatly different.
Therefore, due to the limitation of the processing technology, the equipment which can only be rough-processed, and the finishing equipment such as the machining center, is expensive, and the so-called high-grade configuration aimed at improving the processing precision and efficiency is expensive. It is not scientific. Rather than using the most expensive things on the device, the device becomes a high-end device. To measure whether a device is upscale, the evaluation should be based on the reliability and use of the device (the accuracy, roughness, and production efficiency of the machined parts), rather than the cost of the equipment used on it, not even His price.
This is determined by the flame or plasma cutting process, and in no case can it achieve the same high machining accuracy as other CNC equipment such as CNC lathes. In other words, the accuracy of the device itself is 6 or 8 and it is not very important. From the perspective of production efficiency, the speed of cutting, taking flame cutting as an example, depends entirely on the thickness of the sheet, the type of cutting nozzle, the purity of oxygen, the quality of gas, etc. The moving speed of the equipment should meet and meet the requirements of the cutting process. In other words, the cutting efficiency is not directly related to the device itself. Of course, CNC cutting machines still show considerable precision and high efficiency, but this is relative to manual cutting, and it is not a concept to improve the machining accuracy and efficiency of the machine.
