Precision machining and manufacturing refers to the process of processing and manufacturing materials with high precision by using technologies such as ultra-precision machining with high accuracy, high surface quality, high flexibility, high efficiency and green environmental protection, which is applicable to many industries such as automobile manufacturing, medical equipment, food processing and electronic equipment. Precision machining and manufacturing determines the quality and performance of the product, and is capable of producing high-precision products such as ultra-micro-thin gears with a thickness of <50μm, whose finish can reach Ra50nm, and which can even be engraved on the body of a mite.

The process of precision machining and manufacturing includes three aspects: design and development, machining and manufacturing, and inspection and assembly. The design and development stage requires the design of a processing programme that meets the requirements and feasibility analysis according to the requirements of the product. Processing and manufacturing stage requires the use of a variety of precision machining technologies, such as laser technology, microfabrication technology, EDM technology, ultrasonic vibration machining technology, special machining technology, precision grinding technology, ultra-precision cutting technology and precision mould manufacturing technology, etc., to carry out high-precision machining and manufacturing of materials. The inspection and assembly stage requires inspection and assembly of the finished products to ensure that the quality and performance of the products meet the requirements.

Precision machining manufacturing has a wide range of applications, including aerospace, automotive manufacturing, medical equipment, electronic equipment, precision instruments, optical instruments, semiconductors and other industries. In the context of globalisation, the precision manufacturing industry has had a far-reaching impact on the trading system, including automotive manufacturing, medical equipment, food processing, electronic equipment, and many other industries enterprises to maintain competitiveness, quality assurance, technological optimisation, customised services, and lean management.
