Compared with the international market, the products of China's machine tool industry can not meet the market demand

China is the largest country in machine tool consumption and production, but the machine tool import and export deficit reminds domestic machine tool enterprises that at present, the product structure of China's machine tool industry has fallen rapidly, and the pendulum structure can not meet the market demand

China is the largest country in machine tool consumption and production, but the machine tool import and export deficit reminds domestic machine tool enterprises that the current product structure of China's machine tool industry cannot meet the market demand. Compared with international leading CNC machine tools, domestic CNC machine tools lack independent innovation, and there is still a certain distance in quality stability

the main reason why domestic CNC machine tool users do not choose domestic machine tools is that the reliability of the products cannot meet the user's demand to supply water droplets from a fixed nozzle. The fierce competition in the machine tool market is mainly the competition of product reliability. Whether to occupy the market is the key to the survival and development of China's CNC equipment industry. Especially in the situation of increasing imports, the improvement of product reliability is of great significance for domestic CNC equipment to win in the international market competition and promote the development of national industry

the reliability of products is the key factor affecting market share. In recent years, China's machine tool enterprises have implemented reliability technology, and the reliability level of domestic machine tools is growing steadily, but the gap is still obvious compared with similar products in developed countries. In order to change the current situation of China's machine tool industry, through the implementation of major special projects, we should promote the reliability level of domestic high-end CNC machine tools to approach or reach the world advanced level, solve the engineering problems that hinder the development of CNC machine tool industry technology, and reverse the passive situation of international market competition

at present, the research and development of domestic CNC machine tools are mainly aimed at high-grade, pursuing high-speed, precision and multi axis combined processing. However, with the increase of composite functions and the introduction of intensive technology, unreliable factors and hidden troubles increase. A highly reliable machine tool can receive the effect of several machine tools running at the same time, which can reduce users' downtime losses and maintenance costs. In the process of operation and use, the probability of failure increases, its advanced performance and function cannot be maintained, and its use value is reduced or lost

the reliability of CNC machine tool products is the quality attribute exposed in the process of use and field operation. Considering the time and environmental factors of product use, the reliability level of unused products cannot be truly evaluated. To improve the reliability of CNC machine tools is to reduce or avoid various faults in the working process of products

in many cases, domestic CNC machine tools affect the reliability of products. However, this "maximum" refers to the maximum acceleration in the deceleration process of objects, which is not the maximum in the whole process. Therefore, only based on the above analysis, it is impossible to draw the conclusion that the acceleration is the maximum at the lowest point. The prominent problems are often the manufacturing process, assembly process, the selection of supporting parts and purchased parts, and the early failure has not been eliminated, accounting for a large proportion of failures. Only by emphasizing the reliability test method, strengthening the reliability assurance measures of the product manufacturing process, assembly process, procurement of supporting parts and purchased parts and early fault elimination, and implementing system engineering, can the reliability of CNC machine tool products be finally improved
