Some suggestions for the development of local machine tools

With the rapid growth in the demand for major equipment manufacturing industries such as defense, aviation, high-speed rail, and automobiles in China, our country's machine tools have also achieved rapid development. Machine tool technology has made remarkable progress in terms of speed, compoundness, precision, and multi-axis. And a series of breakthroughs.

It can be said that the level, variety, and production capacity of machine tools directly reflect the overall strength of a country's industry, and the birth of our country's machine tools is slightly behind that of the United States and Germany. With almost half of the world's development, Chinese machine tools are lagging far behind Germany, In the United States, Japan, and other countries, domestically produced machine tools are mainly based on low-end economic models and mid-range universal machine tools. There is still a large gap between local machine tools and foreign machine tools in terms of accuracy and reliability.

At present, in the machine tool products, Chinese enterprises in middle- and low-end products have certain strength, but high-end machine tools are still short, and high-end machine tools are necessary for the four fields of aerospace, automobiles, ships, and power generation equipment manufacturing, and are industrial upgrades. Essential. Recently, Dalian Dalian Machine Tool Group, Dalian Guangyang Technology, Dalian Xingjian CNC, Dalian Far East Tools and other 14 Dalian machine tool companies exhibited intelligent and automated high-end manufacturing hardware and software products, showing the transformation and upgrading of Dalian machine tool industry, replacing the import of manufacturing Strength and first-mover advantage.

At the exhibition, Dalian Machine Tool Group was not satisfied with the largest booth area and scale, and selected high-end manufacturing new products here as "starters." Zhou Yuliang, director of the CNC lathe research institute, told reporters about the advantages of a new type of CNC horizontal lathe: It is an intelligent manufacturing island formed by a machining center and a robot. In the past, a worker could only take care of a machine tool. Now a worker can take care of 8 to 10 intelligent manufacturing islands. Intelligent manufacturing is an advanced stage of automated production. Intelligent manufacturing islands undoubtedly represent an important trend in industrial development.

Dalian Machine Tool is promoting smart manufacturing to change from reducing physical labor to reducing mental work, and is striving to become the first domestic manufacturing expert in the information age. This year, Dalian Machine Tool will build a “Sanping and Cloud”. If it uses the products of Dalian Machine Tool, it is necessary to understand the usage of the equipment and open the mobile phone to sweep “Two-dimensional Code”. The process is clear at a glance.

After 10 years of rapid development, the demand for domestic high-end CNC machine tools and related ancillary products continues to grow. It is the consensus of machine tool companies that positioning high-end products and avoiding product homogenization and price war. At the exhibition, Koyo Technology brought two robot products. The robot hand can not only hold 166 kg and 210 kg of heavy objects, but also can sculpt and cut stone, light aluminum, and wood with an error of no more than 0.01 mm. Europe and the United States advanced level. Yu Dehai, chairman of Koyo Technologies, said that this year, companies must use "smart manufacturing islands" to create "smart manufacturing islands," which means that not only products must be intelligent, but also production processes must be intelligent and informative.

As a result of seeing a huge market space for transformation, upgrading, intelligence and information transformation of domestic enterprises, as a new machine tool service company in the city, Dalian Xingjian CNC independently developed a “manufacturing data acquisition system” for two years to fill the domestic gap. To increase the efficiency of traditional production lines by at least 1x. At present, AVIC Harbin Dongan Engine Group has been installed and used, and CNR Dalian Locomotive Research Institute is being installed.

Although the country has implemented major science and technology special projects for "high-end CNC machine tools and basic manufacturing equipment", and plans to reach 80% of the high-end numerical control machines and basic manufacturing equipment required by the four major fields by 2020, only Jiji Machine Tools has large-scale and high-efficiency CNC controls. A project of automatic stamping production line has been successfully commercialized, and key components and high-end numerical control systems still need to continue their efforts. China MachineNet (Machine35.com) believes that only the improvement of the technical level is the way out. In response, China made a series of recommendations for the development of machine tools in 2014:

First of all, in terms of R&D, the company implements innovative development strategies based on the country's existing special support, with the theme of the enterprise and innovation as the driving force. Given that the machine tools are large investments and slow-seeing industries, they cannot achieve long-term development solely because of their own efforts. A number of enterprises are required to participate in the common technology research and development, and at the same time the research institutions must be involved. At the national level, basic research investment and R&D personnel training should be increased.

Secondly, the machine tool industry must adjust the existing industrial structure and exert high-end forces on the basis of the existing achievements in the mid-end. On the one hand, it needs to face the competitive pressure of foreign products and joint venture products to squeeze the domestic mid-market, and on the other hand, it must increase R&D. , Into the high-end market, get rid of the severe situation subject to control.

In the future, with the increasing emphasis on high-end machine tools in China, after the local machine tool brands have strengthened talent cultivation, the forces will usher in a new period of development.
