As a pillar industry of the national economy, manufacturing industry has created rich material wealth for society, but it consumes a lot of resources and causes environmental pollution. At present, environmental issues have increasingly become a key factor affecting socio-economic development. The environmental protection laws and regulations formulated by various governments have become increasingly stringent, and consumers have also paid great attention to environmental management. Therefore, how to reduce resource consumption and environmental pollution is a major issue facing the manufacturing industry in the 21st century. For this reason, it is imperative to implement green manufacturing technologies in the manufacturing industry and implement sustainable development strategies. Machinery manufacturing plays an important role in China's energy-saving and emission reduction work. Metal-cutting machine tools are machine-building machines and are industrial master machines. The working life of general machine tools is more than 30 or 40 years. It belongs to long-life products. In the life cycle, it is necessary to consume energy as well as produce solid, liquid, and gas wastes, causing direct or indirect pollution to the work environment and the natural environment. Therefore, new types of machine tools that save energy and protect the environment have become the focus of current research.
New Materials for Green Machine Design <br> With the continuous improvement of modern engineering technology and science and technology on the performance requirements of materials, the research and application of new materials have been rapidly developed. New materials represented by composite materials have been widely used in the national economy. each field. In the machinery industry, the emergence and application of new materials has led to major changes in some traditional processing technologies. The development of high-tech industries such as modern aerospace industry has increasingly increased the requirements for the performance, precision, and processing capabilities of CNC machine tools and equipment, and has driven and promoted the development of CNC machine tools and equipment manufacturing.
Due to the characteristics of high-temperature, high-strength, difficult-to-process, high-alloy materials and composite materials, and many complex structural parts and high process requirements, parts of aerospace industry products require large-scale (heavy-duty, super-heavy), high-speed, precision machining equipment. Compound and intelligent trend development. How to give full play to the advantages of new materials, such as process performance, apply it to practice, and become an important issue in the field of machine tool design in the new era.
The application of new materials including carbon fiber, ceramics and composite materials in the machine tool structure has made the machine tool structure lightweight and environmentally friendly, and has promoted the development of high-speed, precision, compound and intelligent machine tool processing equipment. Such as the use of artificial granite granite large-scale support, or in the framework of welded steel plate filled with concrete, not only can save metal resources, but also can increase the vibration resistance and thermal stability; For some stress conditions, complex parts and components Using new materials such as carbon fiber can not only make the machine tool structure lightweight, but also can increase the life; For some high hardness wear parts, the use of ceramics and other materials instead of high hardness steel, can reduce weight, but also can save precious metals Resources can also eliminate time-consuming energy-consuming heat treatment processes that are required for high-hardness steels to be processed multiple times during processing.
For example, in the machine tool industry in countries such as Europe and America, new material resin concrete has been greatly developed, especially in the bed application of high-precision machine tools, resin concrete is gradually replacing the traditional cast iron. Resin concrete is a new type of structural material. It is a mixture of natural ore (different sizes, different sources) and epoxy resin (as binder), which has a great advantage over traditional cast iron. At present, more and more international machine tool manufacturers begin to design resin concrete machine tools, but this field is still blank for the Chinese market. Compared with traditional cast iron, resin concrete has the following four advantages:
(1) Low energy consumption. Compared to cast iron, resin concrete consumes less energy and saves about 30% of energy consumption during the manufacturing process. In the face of energy shortages such as electricity, natural gas, and coal, the use of eco-friendly materials such as resin concrete, which is inexpensive and can be recycled, is the best choice. Resin concrete waste and old beds can be used as building materials.
(2) Good vibration absorption. Nowadays, more and more attention is paid to precision CNC machine tools. In high-speed cutting, workpieces and machine parts move faster and faster. Increasing the speed, feed rate, and increasing the weight of the parts will generate vibrations that reduce accuracy. Resin concrete eliminates vibration and improves the accuracy of the machine.
(3) Highly integrated. Casting temperature of ±45°C for resin coagulation is another advantage compared to cast iron at 900°C casting temperature. The traditional method is to install other components after the bed has been cast. It is now possible to cast components such as pipes, cables, sensors, actuators, and fluid-filled chambers directly into the casting.
