Under the smog, the air pollutants could not spread, and the air quality continued to deteriorate. Just over half a month after the daily air quality of some cities was notified, the Ministry of Environmental Protection launched the “most strict†industrial policy for air pollution prevention and control. The "most strict new policy" directly refers to the six heavily polluting industries represented by steel. The steel industry is restricted to develop, which will definitely affect the development of the machine tool industry. The Ministry of Environmental Protection announced on the 19th that it will focus on four key pollution control industries including steel, petrochemical and chemical industries, and coal-fired industrial boilers, including 47 prefecture-level cities and above in 19 provinces (autonomous regions and municipalities). The new project, the existing projects of thermal power, steel, petrochemical industry and coal-fired industrial boilers, implement special emission limits. Some experts believe that the special emission limits for the six high-emission enterprises are the most stringent atmospheric pollution control measures against the "smog China". Some experts believe that the release of the New Deal will affect the development of the steel industry, and the steel industry is closely related to the machine tool industry: machine tools are composed of steel and an important tool for processing steel. Therefore, the implementation of the new air pollution policy will definitely negatively affect the machine tool industry. influences.
Faced with this situation, the concept of green machine tools was once again raised by the industry. The so-called green machine tool means that the machine tool consumes less energy, is lighter in weight and more efficient during production and use. According to statistics, in the process of cutting parts, only about 25% of the energy consumed is used for metal cutting. This part is useful work. Other energy sources are consumed in maintaining machine operation, ensuring accuracy and rigidity. In terms of auxiliary measures, energy conservation is to reduce this part of the energy consumption, with the least energy consumption to meet the needs of auxiliary functions. Luo Baihui, chief analyst of Jinmo Machine Tool Network, believes that green machine tools are the development direction of future machine tools. Enterprises can focus on the following three aspects to produce more environmentally friendly machine tools:
1. The main parts of the machine tool are made of renewable materials. According to the National Bureau of Statistics, China's manufacturing energy consumption accounts for 60% of total energy consumption, generating 5.5 billion tons of non-hazardous waste and 700 million tons of hazardous waste each year, which is not conducive to environmental protection.
2. The use of renewable materials not only achieves the reuse of resources, but also reduces the production costs of enterprises, which is an important way for the machine tool industry to achieve low carbon environmental protection.
3. The weight and volume of the machine are reduced by more than half. Lightweight is the future development trend of the machine tool industry. Machine tool enterprises can achieve the goal of “green design†by optimizing the design of machine tool structures or components.
4. The material of the scrapped machine tool is close to 100% and can be reused to realize machine tool remanufacturing. Machine tool remanufacturing can not only realize the recycling of waste machine tools, create new value, but also bring a lot of profit space to machine tool enterprises. This model is worthy of the development of the machine tool industry.
At present, many universities and research institutions in China have carried out research in the field of green manufacturing and have achieved certain results. For example, Chongqing Machine Tool Group and Chongqing University have jointly developed a complete set of machine tool remanufacturing and comprehensive lifting technology, and completed the remanufacturing of more than 500 used machine tools. The functions and main technical indicators of remanufacturing machine tools meet or exceed the original machine tools, resource recycling. The utilization rate is about 80%, the noise is reduced by more than 10%, and the environmental pollution discharge is reduced by more than 90%. At CIMT2011, green manufacturing products became a highlight of the show. For example, the electrostatic mist absorbing device developed by Qinchuan Machine Tool has greatly improved the treatment effect of oil mist compared with the traditional filter device, the efficiency is over 96%, the discharged air is basically clean, and the recovered oil mist particles Get repeated use.
The YS3126CNC-CD CNC high-speed dry-cut hobbing machine developed by Chongqing Machine Tool is favored by many users because it guarantees high efficiency, high quality, high tool durability and high work reliability, and does not require the green environmental characteristics of cutting fluid. At the 13th Shanghai International Machine Tool Show, many green manufacturing exhibits and technologies have also become the focus of the exhibition. For example, GE15A ultra-dry cutting high-precision CNC gear hobbing machine exhibited by Mitsubishi Heavy Industries has little impact on the working environment due to the absence of coolant. Without metal cutting, it not only saves raw materials, but also greatly improves work efficiency.
