1. Precision cutting technology
At present, in the process of mechanical manufacturing, the technical methods of high precision machining used in the past are still used. At present, if precision cutting technology is used to improve the smoothness of mechanical surface,
It is necessary to select tools, machine tools, workpieces and other equipment that conform to precision cutting technology to avoid adverse effects. For example, when using machine tools for precision machining, the selected stiffness should reach
To reach a reasonable level of precision machining, it is also necessary to control the thermal deformation performance and anti vibration performance. In order to achieve this standard, the following four high-tech technologies need to be used when processing products,
These four technologies are precision positioning technology, micro feed technology, hydrostatic pressure bearing technology and precision control technology. In addition, in the process of precision machining, the machine tool can also be improved accordingly
Spindle rotation speed, which can improve the precision effect of processing products to a certain extent.
2. Precision grinding technology
Precision grinding technology is usually used in the field of processing components in integrated circuits. In addition, most components in integrated circuits are small. For example, I have been processing silicon chips
In the process, there is such a specific requirement that it must be carried out within 1-2 mm. This function is not included in the previous precision machining and grinding technology, while modern precision grinding technology such as polishing technology
All of them can meet this specific requirement. At present, with the rapid development of China's economy and the continuous improvement of the scientific and technological level, elastic launch and the use of processing fluid produce chemical reactions
Modern precision grinding technology has been developed successively.
3. Micro machining technology
In recent years, the vast majority of electronic components of mechanical processing in China are developing towards intelligence, and have been greatly improved and optimized in terms of volume, weight and running speed,
The former rough mechanical manufacturing and processing technology can not meet the current processing demand for electronic components, while the current micro machining technology can just meet this demand. stay
In the world, if scientific and effective ultra-fine micro ion technology is used to process semiconductors, the precision can reach the level of hundreds of angstroms, which fully reflects the high efficiency of micro processing technology
Energy level.
4. Mold forming technology
At this stage, for various products such as automobiles and aircraft, the component manufacturing of some mechanical processing products comes from mold processing. The key point of mold forming technology is to improve
The precision in mold processing also fully reflects the position of a country's manufacturing level. The electrochemical machining process can not only achieve micro
The mold precision of m level can also avoid quality problems on the product surface.
