Do CNC deep hole processing friends should know that CNC processing, deep hole processing is the most difficult. The so-called deep hole machining is the processing that the ratio of the length of the hole to the diameter of the hole is greater than 10 times. The deep hole processing is applied in some industrial fields of the country, such as the national military rocket body and the barrel of various guns. In these application fields, some require very high quality and precision of machining, and some require high cutting ability of processing materials The so-called CNC is the abbreviation of computer numerical control machine tool, which is the technology required for programmed control, automation and high-tech.
The use of CNC technology in deep hole processing, because of its processing technology and method is very complex, so few people use CNC machining center for deep hole processing. If using this technology, first of all, we should reform the CNC machining center vibration deep hole drilling machine, combine the advanced deep hole machining vibration cutting technology and AC frequency conversion speed control technology organically It has become a kind of precise professional processing technology. This kind of precise CNC deep hole processing technology effectively applies the vibration cutting technology to the drilling process. On the basis of the traditional deep processing technology, the vibration amplitude and frequency of regular vibration are given to the tool. In the process of cutting tool running, the cutting work is completed by vibration at the same time, and the cutting thickness changes periodically, so as to achieve the purpose of NC cutting according to the predetermined shape and size. Thus, the problem of chip removal interruption in CNC deep hole machining is effectively solved, and the quality and efficiency of deep hole processing are improved!
With the rapid development of computer technology, the degree of automation control, intelligent control and other technologies are more and more applied in the field of technology. Computer technology auxiliary functions are more and more applied to automobile manufacturing, home appliance manufacturing, aerospace and communication electronics. Nowadays, most of the labor steps that need manual processing are more and more moving to use computer programming Process can be automatically completed, in the processing lathe, CNC lathe, tool system, and other related technologies efficient organic combination, such as CNC thin-walled processing technology is one of them. Next, the CNC thin-walled processing technology in the CNC machining parts of the size data and structure technology two aspects to talk about its characteristics.
The design of dimension data should accord with the principle of convenient programming. The drawings in the industrial field are very important, but at the same time, they should also be strictly combined with the actual operation needs. If the dimensions on the part drawings are marked, they should adapt to the characteristics of NC machining, that is, they should be guided by the same datum to give the coordinate dimensions directly. This method is suitable for programming and also suitable for the coordination between dimensions, which brings great convenience to the follow-up work. At the same time, the part designer can change the local scattered marking method to the same datum dimension when designing, instead of only considering the assembly characteristics.
The structure process should be in line with the characteristics of NC machining, and the shape and inner cavity of the parts should adopt the unified geometric type and size. In this way, the number of tool change and tool specifications can be reduced in the process of operation, which makes programming convenient and production efficiency higher. In addition, CNC thin-walled machining should also consider the accuracy and dimensional tolerance of parts.
CNC five axis machining is a way of CNC machining. In the machine tool industry, the axis number of CNC machine tools is usually taken as the standard. The axis number below three axis is the resistance, the three to five axis is medium and high-grade, and the five axis machining is higher and higher. Now the modern equipment products represented by CNC five axis machining are developing towards the extreme manufacturing method, which is more and more high, more and more slender and more miscellaneous As the production process is highly centralized, what are the extraordinary strategic significance of China’s CNC five axis machining linkage automation and intelligent CNC machine tools for China’s equipment manufacturing industry
In recent years, with the rapid development of China’s national economy and the needs of national defense construction, more urgent requirements have been put forward for high-grade CNC machine tools. This requirement is not only in quantity, but also in the quality, accuracy, automation and mechanization of their products. The developed western industrial countries, led by the United States, have always regarded the five axis CNC machine tool system as an important strategic material basis, and implemented the export license system, especially the blockade system implemented to China during the cold war. In recent years, with the strong support of the state in this respect, China’s CNC five axis machining technology has been greatly developed on the basis of reference Exhibition, five axis CNC machine tool system for a country’s aerospace, precision instruments, heavy
