Mechanical processing technology analysis
1. Super precision grinding technology
There are strict requirements for the roughness of the machining surface in the processing process. For example, the same level of roughness accuracy should be maintained in (1 ~ 2) cm. In the traditional processing technology, silicon polishing is generally used to achieve this requirement. With the development of the machinery manufacturing industry, the requirements of the surface roughness of the machining construction are higher and higher, and the traditional technology can not meet the current accuracy requirements. Super precision grinding technology can be polished through small parts, can effectively improve the accuracy of parts, to meet the requirements of modern machining.
2. Precision cutting technology
The technology has high requirements for machine tool equipment, this is because the equipment required by some industries is extremely high, the error must be controlled in a minimal error, in order to avoid other factors to machining precision may bring factors, require machine tool equipment has enough accuracy, so as to deal with its details.Due to the high cost, high technical requirements, complex operation and many other factors, the technology is mainly used in the manufacturing and processing of precision products, mainly responsible for high precision cutting work. In order to make the surface of the rough component more detailed and smooth after high precision machining, the camber of the machine tool equipment has to be improved in its operation, so as to ensure that the equipment and components will not be deformed when the processing temperature increases.In order to achieve the requirements of precise cutting, the present machinery manufacturing industry in our country mainly by increasing the spindle speed of machine tool to meet its requirements, can reach the level of tens of thousands of revolutions per minute at most. In addition, with the progress of modern science and technology, advanced technology also provides enough support for the machinery manufacturing industry, including precision positioning and other advanced technology can also achieve the effect of precision machining.
3. Part drawing analysis
The most important thing for CNC turning is the analysis of drawings, especially the analysis of parts, speed grid according to the details marked on the drawings to consider the next process of the process, and the special analysis of more precise instruments, whether to meet the requirements of the process, but also need to adjust the material and structure according to the process requirements. Parts processing, there are professional staff to give quotation and processing technology guidance.
① Select the benchmark. Drawings will generally give the standard size of the parts, of course, this standard is a broad standard, not suitable for all the process and material, but in most of the process, this benchmark is more suitable, this standard is conducive to the organic integration and unity of the whole system in the process.
② Calculation of node coordinates. In many drawings, mathematical models are used to program, so geometric figures in mathematics are used to program in programming.
(3) Analysis of precision and technical requirements. Mechanical process has a very high requirement for precision and accuracy, so only in each part of the material and technology are very consistent conditions, through the strict process, in order to process the finished product with high accuracy.
