With the continuous development of automation equipment, the market is developing in full swing, which is a good benefit for businessmen. It can develop to this day, which depends on the hard work of technicians. Precision hardware and mechanical parts processing is one of them, so how to process precision hardware and mechanical parts?
Precision mechanical parts processing is a kind of mechanical processing, but it has higher error requirements when stopping processing, and stricter requirements on processing technology. With the development of modern industry and the changing needs from time to time, fine mechanical processing has been a multi-faceted development. Its development direction is getting wider and wider, and the direction is getting finer and finer. The direction of development is showing more and more specialization. With the development of science and technology, its technology is also constantly improving, the quality and accuracy of processing are getting higher and higher, and the development of science and technology and economy has also tightly controlled the direction of development of precision mechanical processing.
With the development of the machinery industry, new design theories and methods, new materials, and new processes have emerged, and mechanical parts have entered a new stage of development. Theories such as finite element method, fracture mechanics, elastic fluid dynamic lubrication, optimization design, reliability design, computer-aided design (CAD), solid modeling (Pro, Ug, Solidworks, etc.), system analysis, and design methodology have been gradually used in the research and design of mechanical parts.
Precision machining will only become more and more integrated. It is no longer just a simple form of machining. At the moment when it is seamlessly connected with high technology, it can play a better role, especially in the digitalization of the machining industry, which has made its development a qualitative leap and can better serve industrial development.
Features of precision mechanical parts processing:
1. When the precision of precision parts processing is in nanometers, or even in atomic units, the ultra-precision parts cutting processing method can no longer adapt, and it is necessary to use special precision parts processing methods, that is, to apply chemical energy, electrochemical energy, thermal energy or electrical energy. Make these energies exceed the binding energy between atoms, so as to remove the attachment, bonding or lattice deformation between local atoms on the surface of the workpiece to achieve the purpose of ultra-precision processing. This type of processing includes mechanical chemical polishing, ion sputtering and ion implantation, electron beam exposure, laser beam processing, metal evaporation and molecular beam epitaxy.
2. Mainly precision turning, mirror grinding and lapping, etc., micro-turning is performed on a precision lathe with a precision-ground single crystal diamond turning tool, and the cutting thickness is only about 1 micron. It is often used to process high-precision and highly bright parts such as spherical, aspherical and flat reflectors of non-ferrous metal materials.
