The overall rate of numerical control in China is increasing year by year. According to statistics, the numerical control rate in China has increased from 3.2% in 1992 to 13.3% in 2012. However, Luo Baihui, chief analyst of Jinmo Machine Tool Network, pointed out that this compares with 60% to 70% of the output of the developed countries such as Japan, the United States, and Germany, and the rate of numerical control of the production value of 80% to 90%. The level of numerical control is still too low.
Although China's machine tools currently hold nearly 7 million units, it has become the world's largest machine tool holder, but the overall level of machine tools is still relatively backward. Many products before the 1980s are still in overdue service, and it is difficult to meet the requirements of machining accuracy. . If the 3% annual machine tool retirement elimination rate is estimated, nearly 200,000 machine tools will face obsolescence, idleness, technical or functional phase-out each year, accounting for about half of the annual production of new machine tools, the "12th Five-Year" period will be Nearly 1 million machine tools face various forms of scrapping, which not only presents opportunities for remanufacturing, but also demands for remanufacturing and upgrading.
According to statistics, currently more than 60% of machine tools have a service life of more than 10 years. These machine tools may face overhaul or even functional scrap or technical elimination in the next 5 to 10 years, resulting in considerable recyclable potential resources for remanufacturing. .
In addition, many precision machine tools and large (heavy) machine tools in China rely mainly on imports. According to incomplete statistics, from 1979 to 1988, there were 18,446 imported technological transformation projects in the country, totaling approximately 16.58 billion U.S. dollars. The prices of these major machine tools are extremely expensive, and they are facing scrapping in succession since 2001.
Faced with the development trend of China's transformation from a manufacturing country to a manufacturing powerhouse, these various forms of scrap and old machine tools will be transferred to the ranks of machine tool remanufacturing.
Analyst Luo Baihui believes that the development and emergence of machine tool remanufacturing in China can not only realize the recovery, recycling and reuse of old machine tool equipment resources with large scale, save resources and energy, reduce environmental pollution, but also form an emerging machine tool remanufacturing. With the service industry, it has important economic, social and environmental benefits.
