Precision machining is a process of removing excess raw materials from a workpiece while maintaining tight tolerances and smoothness to manufacture finished products. Its processing characteristics can be summarized as follows: 1. High precision at the micrometer or even nanometer level: Precision machining technology can achieve precise control of part processing accuracy by using good processing equipment and process methods, and the processing accuracy can usually reach the micrometer or even nanometer level. Hoc machina precision alta potest occurrere ad requirem partes altas precision in agris, quasi aviatio, aerospace et instrumenta precision. High surface quality: Precision machining technology can also achieve precise control over the surface quality of parts. By optimizing machining parameters and process methods, parts with extremely low surface roughness and high consistency can be obtained. Hoc typus komponentis qualitatis altae superficie habet multas aplicationes in agris, quales optica, electronica et medica. 2. High flexibility and wide applicability: Precision machining technology has a wide range of applicability and can be combined with various materials and processing techniques to achieve machining of parts of different shapes, sizes, and materials. Hoc flexibilitate tecnologiam machinationis precisionis possunt adaptare ad necessitates diversorum industriarum et aplicationibus. Multi process combination: The precision machining process involves various processes such as turning, milling, drilling, gear cutting, grinding, as well as special processes such as heat treatment, such as carburizing, quencing, tempering, etc. Combinatio haec procedentium ultra flexibilitatem et processionem capabilitatem machinae precisionis elevat. 3,High efficiency automation and intelligence: With the development of automation and intelligence technology, precision machining technology has achieved a high degree of automation and intelligence. By adopting numerical control technology, automated detection technology and other means, precise control and optimization of the machining process can be achieved, improving machining efficiency and reducing production costs. Fast turnover and reliable service: Precision machining technology can provide customers with fast turnover delivery and reliable service. Quando cyclis production is celerior est, non significat diminutionem qualitatis. Enginei precisiorum professionales in omni processione qualitatem conservabunt ut productionem voluntatis magnitudinis perfectionis assecurant. 4, / Green environmental protection reduces waste and pollutant emissions: Precision processing technology focuses on environmental protection and sustainable development. By adopting advanced processing equipment and process methods, the emission of waste and pollutants during the processing process can be minimized, reducing the impact on the environment. Material conservation: Precision machining technology can reduce the waste of raw materials. Although engineering and manufacturing industries are expected to generate a certain degree of waste, the application of precision machining will greatly reduce waste, significantly save manufacturing costs, protect the environment, and maximize the use of expensive materials. 5,Other characteristics are interrelated: Precision machining technology is an important component of mechanical design and manufacturing, and there is a strong correlation between the two. Precision machining technology not only affects the quality of products, but also has a certain connection to the sales and use of products. Evolutionary processing: Sometimes, equipment and tools with lower precision than the workpiece can be used to process the working mother machine or workpiece with higher precision than the "mother machine" through process means and special process equipment. High processing environment requirements: Precision and ultra precision processing environments must meet the three environmental requirements of constant temperature, vibration isolation and ultra cleanness. High material requirements for workpieces: The workpiece material must have uniformity and consistent performance, and internal or external micro defects are not allowed. Precision measurement: Precision measurement is a necessary condition for precision machining and ultra precision machining. Sine techniques measurement compatibles sunt cum machina precision, impossibile est precision artificis machinae determinare.
