The mechanical manufacturing industry refers to the industry engaged in the production of various power machinery, lifting and transportation machinery, agricultural machinery, metallurgical and mining machinery, chemical machinery, textile machinery, machine tools, tools, instruments, meters, and other mechanical equipment. The mechanical manufacturing industry provides technical equipment for the entire national economy, and its development level is one of the main indicators of the country's industrialization level, and is an important pillar industry of the country.

The entire essence of advanced manufacturing technology lies in its application. The development of mechanical automation technology should be guided by the actual needs and specific conditions of enterprise production and development. Only by adopting appropriate automation methods for the production of suitable products can good technical and social economic benefits be achieved. To develop mechanical automation technology in China, we should combine it with reality and pay attention to practicality, that is, to generate practical benefits for the national economy. The tendency towards blindly implementing automation and automated production lines, which require only 1-2 months to complete production tasks throughout the year, should be corrected, and those that do not significantly promote the national economy and have low efficiency should be postponed. What we want is efficiency, not just speed.

Developing low-cost automation technology has great potential, broad prospects, low investment, quick results, and improving automation level can achieve twice the result with half the effort. It is suitable for the current development needs and national conditions of China. In the second half of the 20th century, the Lean Production (LP) model, initiated by Toyota Motor Corporation of Japan, is a concrete manifestation of achieving the maximum output with the minimum input. It is beneficial to learn from the experience of developing low-cost automation technology in the mechanical manufacturing industry abroad. Each enterprise in China's mechanical manufacturing industry has a large number of general equipment. When developing modern mechanical automation technology, it is necessary to focus on existing equipment, adjust the layout of machine tools reasonably, add a small amount of CNC equipment, introduce CAD/CAM technology, fully leverage the advantages of computer automation management and human creativity, and jointly form a people-centered, information automation led, and independent modular production system, This provides a new approach for the development and application of automation technology in China's mechanical manufacturing industry, which is characterized by low investment, fast effectiveness, high efficiency, and in line with China's national conditions. In the long run, gradually improving manufacturing production in development and achieving sustainable development require the joint efforts of every entrepreneur and country.
