Technical development of precision parts processing. Precision parts are used in communications, automobiles, watches, medical, computer, aerospace and other industries. Different from ordinary parts, precision parts have higher precision and are more suitable for writing. In industries with relatively high precision, the technology development of precision parts processing.
Before the industrial revolution, most of the machinery was hand-made wooden structures. Metal was only suitable for manufacturing instruments, watches, pumps, locks, and small parts on wooden structure machinery. Metal processing was mainly based on the finesse of the machining staff. The operation reaches the required precision. With the widespread use of steam engines and the subsequent development of large-scale machinery such as metallurgy, mining, transmission, and locomotives, more and more metal parts need to be formed and cut. The metal materials used are copper and iron. Developed to mainly steel; the rapid development of precision processing equipment and machining has ensured the supply of various mechanical equipment required for production, and with the increase in production batches and the development of precision processing technology, it has promoted the formation of a large number of production methods .
