At present, the total number of machine tools in my country is more than 3.8 million, of which the total number of CNC machine tools is only 113,400, that is, the CNC rate of my country's machine tools is less than 3%. In the past 10 years, the annual output of CNC machine tools in my country is about 0.6 to 0.8 million, and the annual output value is about 1.8 billion yuan. The CNC rate of the annual output of machine tools is 6%. More than 60% of my country's machine tools have been in service for more than 10 years; among the machine tools under 10 years, less than 20% are automatic/semi-automatic machine tools, and FMC/FMS and other automated production lines are even more rare (automatic and semi-automatic machine tools in the United States and Japan account for 60%). above). It can be seen that most of the production and processing equipment of most of our manufacturing industries and enterprises are traditional machine tools, and more than half of them are old machine tools with a service age of more than 10 years. The products processed by this kind of equipment generally have poor quality, few varieties, low grades, high cost and long supply period, thus lacking competitiveness in the international and domestic markets, which directly affects the products, markets, and benefits of an enterprise. The survival and development of enterprises. Therefore, it is necessary to vigorously improve the numerical control rate of machine tools.
Since my country's reform and opening up, many enterprises have introduced technology, equipment and production lines from abroad for technological transformation. According to incomplete statistics, during the ten years from 1979 to 1988, there were 18,446 technological transformation projects introduced nationwide, worth about US$16.58 billion.
Most of these projects have played their due role in my country's economic construction. However, in some imported projects, due to various reasons, the equipment or production line cannot be operated normally, or even paralyzed, which affects the benefits of the enterprise and seriously puts the enterprise into trouble. After some equipment and production lines were imported from abroad, some were poorly digested and absorbed, with incomplete spare parts and improper maintenance, resulting in poor operation; some only paid attention to the introduction of equipment, instruments, and production lines, ignoring software, technology, management, etc., resulting in project failure. Complete, the potential of the equipment cannot be brought into play; some can not even start operation and fail to play its due role; some production lines have good product sales, but cannot reach production standards due to equipment failures; some are due to high energy consumption and low product qualification rate And cause losses; some have been introduced for a long time, need to carry out technical update. For various reasons, some equipment not only does not create wealth, but consumes wealth.
These unusable equipment and production lines are a burden, and they are also a large number of stock assets. If they are repaired, they are wealth. As long as the main technical difficulties are identified and key technical problems are solved, the largest stock assets can be revitalized with the smallest investment, and the greatest economic and social benefits can be achieved. It's also a huge remodeling market.
