The former pursues the precision and surface quality limit of processing, the latter includes the automation of product design, manufacturing and management, which is not only an important means to quickly respond to market demand, improve production efficiency and improve working conditions, but also an effective measure to ensure product quality, the two are closely related, many precision and ultra-precision machining rely on automation technology to achieve the expected goals. Much manufacturing automation relies on precision machining for accuracy and reliability. Both have an integral and decisive role and are the pillars of advanced manufacturing technology.

Therefore, it mainly includes metal products industry, special equipment manufacturing industry, automobile manufacturing industry, railway, ship, aerospace and other transportation equipment manufacturing industry, electrical machinery and equipment manufacturing industry, computer, communication and other electronic equipment manufacturing industry, instrument and meter manufacturing industry.
