Not only domestic machine tools are affected, but also imported machine tools have been affected. In addition to the relatively high demand for high-end machine tools, the import of machine tools has also declined in recent months. The technical level of domestic enterprises is still far from the foreign countries, but they are very close to each other. Excessive competition in the industry has reduced the gross profit of high-end products, and business development is difficult.
Industry experts believe that China's machine tools must be upgraded in order to upgrade, and increase the added value of users through intelligent innovation. In the total market consumption of Chinese machine tools, 60% rely on imports, joint ventures, and 40% from domestic production. The competition of 40% of domestic machine tools is mainly low-end products, and most of the imported products are high-end products. Although China's machine tools have made great progress in the past decade, the problem of arrogance still shackles the pace of progress. On the one hand, low-end production capacity is excessive, and on the other hand, high-end production capacity is obviously insufficient.
From the perspective of the supply side, many machine tool manufacturers, under the pressure of the market, first think of price cuts and shifting to the supply chain instead of trying to increase the added value. Excessive pursuit of cost reduction, resulting in a decline in supporting quality, vicious price competition, poor corporate profits, limited profitability, so that enterprises weaken the ability to re-development.
From the user's side, because the user is too simple, convenient, and easy to use, the machine tool is too standardized and the process adaptability is not good. If the secondary development and innovation in the machine tool manufacturing process cannot be utilized, and the upstream and downstream process routes cannot be well integrated, the level of China's machine tool manufacturing will be difficult to reach the international first-class.
Recently, the National Development and Reform Commission, the Ministry of Finance, and the Ministry of Industry and Information Technology jointly issued the "Notice on Organizing and Implementing the Special Project for the Development of Intelligent Manufacturing Equipment in 2013", requesting to continue to organize the implementation of special projects for the development of intelligent manufacturing equipment. One of the main contents of China's special support in 2013 is the digital workshop, which aims to promote the application and system integration of intelligent manufacturing system innovation products in the fields of machinery manufacturing, textile, printing, bio-pharmaceutical, composite materials, etc., and improve the level of manufacturing intelligence.
Chinese machine tool enterprises want to develop and advance. First, they must update their concepts. A company's innovation must have advanced innovative ideas and methods. Secondly, it has a profound corporate culture, including systems and systems, and runs through technology and management. Second, a good company must have high quality and social responsibility. Machine tool manufacturing must be intelligent, first of all, the machine tool developer's thinking is intelligent, and the intelligence must require the CNC system with the machine tool to have a good openness, which is a key prerequisite for intelligent manufacturing.
In order to transform and upgrade the machine tool industry, it is necessary to find the right direction and method, that is, to build intelligent multi-dimensional management systems (laws, systems, policies and measures), strengthen intelligent manufacturing, and establish synergies with them. With a high independent quality control system.
HHCMS-200 carbon molecular sieves
CMS-200 is a new kind of non-polar adsorbent specially designed for extracting nitrogen-rich gas from air. It is suitable for separating nitrogen from air. It has a high adsorption capacity for oxygen and can separate nitrogen from air.
The most notable feature of the Carbon Molecular Sieve is its high gas-producing efficiency, especially the preparation of nitrogen with a purity of less than 99.5%.
It is widely used in large air nitrogen making equipment.

Pay attention to
1. The nitrogen production equipment can reduce the adsorption temperature to better show its excellent nitrogen production performance under conditions;
2. Pay attention to low temperature drying and seal preservation during storage;
