CNC cutting machine steel processing requirements and applications

With the development of modern machinery processing industry, the requirements for the quality and precision of cutting have been continuously improved, and the requirements for improving production efficiency, reducing production costs, and having high-efficiency automatic cutting functions are also increasing. As a part of the cutting machine industry, the products we provide will be the most modern and technological. Welcome everyone to discuss cooperation. Details:/
In the cutting industry, regardless of the numerical control flame cutting machine or the numerical control cutting machine, because the cutting width is affected by many factors such as the cutting nozzle, no matter how high the accuracy of the equipment itself, the accuracy of the parts cut out by the cutting tool is generally inaccurate. At ±0.5mm, the error is several orders of magnitude higher than the device itself. That is, it can only be done if millions of huge amounts of money are spent on imported CNC cutting machines. This is determined by the cutting process and method of the flame or plasma. In any case, it cannot obtain the same high standard of machining precision as other CNC equipment such as CNC lathes. In other words, whether the accuracy of the device itself is 6 or 8 is not very important. From the point of view of production efficiency, the speed of cutting is based on flame cutting, for example, depending on factors such as the thickness of the plate, nozzle type, oxygen purity, and gas quality. The moving speed of the equipment should meet and adapt to the requirements of the thermal cutting process. In other words, the cutting efficiency is not directly related to the equipment itself.
At present, many steel deep processing uses a large number of CNC cutting products when cutting various metal plates and pipes. For example, a portable CNC cutting machine can be used for the displacement of movable plates through his lightweight advantages. In addition, when they encounter cutting of large-size metal sheets, they will choose the Gantry CNC cutting machine, because this cutting machine has a bilateral drive, making it more stable when cutting sheet metal. Because it is a gantry structure, it has large specifications, large format, and high stability. Sources are favored by customers. In production practice, people have a common concept: using numerical control equipment, can get high-precision, high-efficiency use results; in the same type of equipment, imported, high-end configuration of equipment, with higher accuracy and higher production effectiveness. Jufeng CNC believes that for a flame or CNC plasma cutting machine, it is not just a CNC cutting machine that can achieve high precision and high efficiency.
In general, the CNC cutting machine still embodies "relative high precision and high efficiency." This kind of "relative" is based on manual cutting and it is not a concept with the improvement of machining accuracy and efficiency. From the above analysis, it can be seen that neither the domestic nor the imported CNC cutting machines will have much difference in terms of cutting accuracy and production efficiency. Therefore, Jufeng CNC believes that for flame NC or CNC plasma cutting machines, due to the limitation of the processing technology, it is a “roughing” device relative to a type of finishing equipment such as a “machining center”. It is unscientific to pursue the so-called "high-end configuration" aimed at improving the accuracy and efficiency of processing, as with a type of finishing equipment such as a "machining center." Instead of using the most expensive components on the device, the device becomes a high-end device. In general, the use of a flame CNC cutting machine or a CNC plasma cutting machine is a result of the use of "coarse grains." They are not comparable to laser cutting, so whether flame cutting or plasma cutting, they are not able to achieve the fine effects of lasers.
For such CNC cutting machine equipment, under the premise of meeting the requirements of cutting various processes, the pursuit of equipment should be:
1. The cutting work environment of CNC cutting is poor, the dust is large, the temperature changes greatly, the equipment runs with vibration, and sometimes there is strong interference power. The reliability of the CNC cutting machine is the most important thing.
2, software and hardware performance can meet the various cutting process requirements.
3, CNC cutting machine operating system compatibility, stable and reliable operation.
4, has a better ease of operation, on-site performance is good, in line with China's national conditions, so that each front-line workers easy to operate and maintain.
The thermal cutting machining method adopted by CNC cutting machine theoretically can be used to process various types of steel materials. However, from the perspective of actual cutting results, in order to improve the precision and finish of cutting, the surface of the steel plate needs to be pre-cut during cutting. To do pretreatment, the following Wuhan Huayu Cheng CNC will introduce in detail the processing requirements of the CNC plasma cutting machine in the early stage of processing.
The practical process of barrel finishing finishing technology is: degreasing treatment → finishing and deburring → sorting → cleaning → drying → anti-rust treatment degreasing treatment: the parts before finishing must be thoroughly deoiled, Ultrasonic cleaning is often the best method. If the oil on the workpiece enters, the cutting force of the grinding block is obviously weakened, the effect of the grinding agent will be reduced, the effect of the smoothing and the efficiency will be reduced, and the surface of the part after finishing will not be bright.
Finishing: Finishing is mainly based on the structural shape, size, and finishing requirements of the finished part, or the selection of the equipment form, equipment specification, process material, and process parameters.
The finishing process includes three aspects: the separation of the grinding block and the workpiece, the cleaning of the grinding block and the workpiece, and the dehydration and rust prevention of the workpiece.
The common methods for separation of grinding blocks and workpieces are: manual screening, mechanical screening, vibration screening, manual electromagnetic separation, and conveyor magnetic separation, which can be selected according to actual conditions. Ultrasonic cleaning is the best method for cleaning blocks and workpieces. Rinse with clean water. Pay special attention to dehydration, drying, and rust prevention.
