Rolling functional parts products include ball screws, rolling linear guideway vice, ball spline, ball guide, linear motion parts, coordinate table, self-locking device. They are characterized by \"rolling\", with high efficiency and energy saving, precision positioning, precision guidance, fast response to CNC commands and transmission of high-speed, synchronization, reversibility and other functions, is an irreplaceable key supporting CNC machine tools and mechatronics products, but also in line with the 21st century ecological, environmental protection concepts of the important basic components.
They are small products, but the integration of many key technologies for precision parts manufacturing, due to their standardization, serialization, high degree of generalization, but also a broad market, very conducive to the organization of specialized mass production, at present, China's rolling functional parts production enterprises have 50, research institutes, universities **** 3, enterprises affiliated with the research institutions of 3. To large-scale intensive manufacturing cost and speed .
Provide a full range to meet the user's individualized needs of many series of products, the production of ball screws of 48 enterprises, the annual output value of up to 650 million yuan, the production of rolling linear guide 6 enterprises, the annual output value of up to 150 million yuan. In the 50 enterprises, large-scale production, process equipment, production of large, varied enterprises have 6, the vast majority of the rest of small-scale enterprises, production is not high, a single product variety.
Domestic rolling components in the equipment manufacturing industry has been applied to a number of fields up to \"Fengyun 2\" satellite, missile guidance systems, space capsule space drive, radar devices, airport equipment, down to various types of numerical control machine tools, IT industry, metallurgical equipment, railway vehicles, nuclear power plants, plastics machinery, medical equipment and so on. Enterprise capital is strong, the speed of industrialization, product originality is strong, new product development speed .
The overall level of foreign rolling parts industry and product development trend has the following characteristics, while high-performance, high-grade products, including high-speed, high-precision, ultra-high-precision, low-noise, etc. and NSK, THK, Rexroth and other well-known enterprises there is a significant gap, becoming a bottleneck restricting the development of domestic high-grade CNC machines, such as large-scale production, high level of information technology management, and very sensitive to market demand. Market demand response is very sensitive .
Every year, a number of new products with the flavor of the times of independent intellectual property rights, and quickly apply for patents, from a global perspective, China's rolling functional parts industry, although the largest number of manufacturers in the country, but the production is not centralized, the distribution of irrational, the total production and output value is not high, in addition to a small number of key key enterprises in some of the products to reach or close to the level of foreign countries, the majority of enterprises can only produce low and medium products, and a single variety, the content is on the high side. And a single variety, low gold content.
To date, there is no one in the international influence of well-known brands, there is no one listed company. From the overall level of products, we are in the developed countries under the brand-name products, developing countries above the upper level of the middle, low-grade products and similar products abroad, the gap between small or basically the same, but the production efficiency is far lower than abroad. To provide quality assurance for mass-produced products and research and development of new products, with testing data and performance comparison curve to win the trust of users, high level of technology, equipment, high rate of numerical control, high production efficiency, product quality and stability, with advanced testing instruments and product performance test equipment, not only to provide users with the required hardware commodities, but also provide users with solutions to the software services,
