Machine tool manufacturing should also be low-carbon
Machine tool manufacturing should also be low-carbon
The current development trend of CNC machine tools is high speed, high precision, compound processing and multi-axis linkage. However, this development trend, which only focuses on the improvement of technical performance, is far from meeting the requirements of the current scientific and technological trends. As an important tool in the manufacturing industry, machine tool development will also consider the harmony of the relationship between the machine tool and the environment and users. Only high-performance, green and intelligent integration and integration can create a new situation of future-oriented high-performance CNC machine tools.
Over the past 10 years, the world's leading machine tool manufacturers have been committed to improving the performance of CNC machine tools, constantly surpassing each other and launching dazzling new products. For example, compound processing machine tools, parallel motion machine tools, inverted processing machine tools, ultra-precision machine tools, etc. It can be predicted that in the next 10 years, machine tool manufacturers and R & D institutions will compete for the commanding heights in the relationship between machine tools and the environment and people, and form new products of "overtaking" competitors, such as intelligent machine tools, network machine tools, green machine tools Meet the needs of industrial transformation and upgrading and the development of a low-carbon economy.
Machine tools are widely used equipment in the machinery manufacturing industry and are energy-using products (EnPenergyUsingProduct, or EuP). Its design, manufacture, use and recycling will be restricted by relevant regulations and standards. In October 2008, the European Commission submitted to the European Parliament a work plan for the "Eco-design Guidelines for Energy-using Products" from 2009 to 2011, listing machine tool products as one of the top ten energy-using products. The "Pre-research of Machine Tool Ecological Design" project carried out by the Microsystems Assembly and Packaging Research Institute and the Institute of Production Equipment and Design Technology of the Fraunhofer Institute for Applied Research Promotion in Germany is expected to introduce relevant regulations or directives in 2012. Restricting energy consumption will definitely create new "green barriers" to China's machine tool product exports.
Energy saving and emission reduction is the era mission of industrial production in the 21st century, and it is also the need for the sustainable development of China's economy. China is a major machine tool producing and consuming country in the world, with about 7 million machine tools. If each machine saves 1kWh per day, it will be possible to save more than 2 billion kWh of electricity throughout the year.
So, how to realize low-carbon machine tools at this stage?
Most of the machine tools in China are outdated, have a long service life, and are out of repair. First of all, the idle running power measurement should be carried out on the machine tools that have been in service for more than 5 years, and the machine tools with low operating efficiency and high energy consumption should be repaired or eliminated.
Secondly, because the production efficiency of machine tools is mainly reflected by high-performance tools, advanced tools and reasonable cutting parameters are used to reduce the energy consumption required to remove chips per unit volume, or to increase the value created by unit energy consumption.
Secondly, with the help of programming software, the NC program is optimized to keep the tool trajectory in a continuous motion state as much as possible, reducing sudden changes in the movement direction and speed to reduce the energy consumption of the drive motor.
Third, the energy management of the machine tool uses low-energy and high-efficiency hydraulic, pneumatic, lubricating and cutting fluid auxiliary devices to reduce energy consumption in the non-cutting process, and timely shut down the power of auxiliary devices that are not in use.
Finally, it should also be noted that the cutting fluid is an indispensable auxiliary material in the use of the machine tool, and is also the main source of pollution. With the advancement of tool coating technology, dry cutting will gradually be applied. Currently, the use of micro lubrication technology (MQL) is the first choice for promoting green manufacturing.
In fact, the main feature of the so-called green ecological machine tool is the lightweight design of its components, especially the moving parts. The lightweight design is mainly reflected in the following four aspects:
The first is a new structure, which uses a rod mechanism, a welded structure, a box-in-box structure, and a Taichung platform structure to reduce the power of the motor driving the moving parts through light weight and direct drive. The second is to optimize and simulate the structure of the machine tool with the help of the computer. On the premise of ensuring the rigidity of the machine tool, reduce the wall thickness and weight of the casting, but it is not an easy task to obtain a high-quality thin-walled casting. Many materials and casting processes The problem remains to be solved. The third is the application of new materials, using aluminum alloy, carbon fiber, engineering ceramics and other materials instead of steel and cast iron to manufacture machine tool parts. However, its economy and reliability need to be further evaluated. The fourth is adaptive control, which monitors the dynamic performance of the machine tool in real time when developing an intelligent machine tool and suppresses or compensates when vibration occurs.
The low-carbon economy involves thousands of households, whether they are ordinary people or businesses. If more than 5,000 machine tool manufacturers in China and hundreds of thousands of machine tool manufacturers pay attention to it, it is said that a small step today will be a big step for China's manufacturing industry to move towards a low-carbon economy.
