With the development of automation equipment from time to time, the development in the market is in full swing, which is a good profit for businessmen. It can be carried out to this day, it depends on the hard work of the technicians, the processing of fine hardware and mechanical parts is one of them, so how to process the fine hardware and mechanical parts?
Precision mechanical parts processing is a kind of mechanical processing, but it has higher error requirements during processing and more stringent requirements on processing technology. With the development of modern industry and the changing demands from time to time, precision machining used to be a multifaceted development. The direction of its development has become wider and wider, and the direction has become more and more detailed. It's specialization. With the development of science and technology, its technology has also progressed from time to time, and the quality and accuracy of processing have become higher and higher. The development of technology and the economy has also tightly controlled the direction of precision machining.
With the development of the machinery industry and the presentation of new design theories and methods, new materials, and new processes, mechanical parts have entered a new stage of development, such as finite element method, fracture mechanics, elastohydrodynamic lubrication, optimized design, and reliability design, Computer-aided design (CAD), solid modeling (Pro, Ug, Solidworks, etc.), system analysis and design methodology and other theories have gradually been 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 machining method. At the moment when it is seamlessly linked with high-tech, it can play its role better, especially in the digitalization of the machining industry, which has made a qualitative leap in its development and can better serve the development of the industry.
Processing characteristics of fine mechanical parts:
1. Machining of precision mechanical parts
When the machining accuracy of precision parts is nanometers, and then atomic units are used as the purpose, the cutting methods of ultra-precision parts can no longer be adapted, and it is necessary to rely on special precision parts processing methods, that is, the application of chemical energy, electrochemical energy, thermal energy or electrical energy. Make these energy surpass the separation energy between atoms, thereby removing the adhesion, separation, or lattice deformation between some atoms on the surface of the workpiece to achieve the purpose of ultra-precision machining. 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. Cutting and processing of precision mechanical parts
Mainly include precision turning, mirror grinding and grinding, etc. The micro-turning is stopped on the precision lathe with a finely ground single-crystal diamond turning tool, and the cutting thickness is only about 1 micron. It is often used to process high-precision, high-brightness parts such as spherical surfaces of non-ferrous metal materials, aspheric war surface mirrors, and so on.
