Inheritance and innovation

All abilities are based on manufacturing capabilities, otherwise they are "lie."

The real and powerful logo of China is not on the shelves of global supermarkets, on Amazon's website, but in workshops in Germany and the United States.

Inheritance

In the context of the current new normality in machinery manufacturing, innovation is a reference to hear in various forums or interviews. However, at a meeting on innovation in the machine tool industry, Chen Hu, chief engineer of Dalian Guangyang Technology Engineering Co., Ltd. and general manager of Dalian Kede CNC Co., Ltd., put forward his thoughts on inheritance.

For thousands of years, the machine tool has been continuously improved, and the precision and efficiency have been continuously improved. Some people may say that this is the inevitable result of several generations of industrial revolution. This brings up a problem. How is the machine with nanometer accuracy made? If it is a device with higher precision, where does the higher precision device come from?

He believes that the seemingly simple problem implies a profound truth. The essence is that the participation of human intelligence and skills makes the machine tool evolve.

This is because "assembly" is not only "installed" but also "matched", "installed" is embodied in the execution of the established craft route, and "matching" reflects the participation of human wisdom. This is why robotic assembly has not been used in machine tool manufacturing until now, and the traditional process number of “scraping” has been retained in many aspects of modern machine tool manufacturing to correct the machining errors.

Because the high-precision machine tool manufacturing is a high-quality manufacturing technology from advanced materials technology, processing technology, assembly technology, and control technology, these technologies have almost accumulated the manufacturing technology achievements of human civilization for nearly 200 years. Most of them cannot be replaced and crossed by “revolutionary innovation”, and the carrier of considerable skill is high-tech workers. Of course, there is the contribution of control technology, and it can also be seen as the extension of human intelligence through computers.

Chen Hu said that if you think from this point of view, it is easy to understand why so many machine tool factories in Europe have their own schools, and they are always proud to introduce their schools to customers, because this is the other side to showcase the technology heritage. the power of. "We can also reflect on the fact that our machine tool industry, in addition to making products with the help of the former Soviet Union's big brother, also helped us to establish a training system and assessment system, but many of these systems were disintegrated before the disintegration of the former Soviet Union."

In his view, the industrial form of high-end machine tools and high-end automotive products is very similar, both of which are reflected in a large number of customized customized production, processing according to orders, intensive manual assembly, high-speed machinery from parts to the whole machine running accuracy Nearly demanding requirements. The output is similar (Maybach's annual production is only 500 units, while Rolls-Royce's annual output is 1,000 units), the price is basically the same, and the service life is also equivalent (10-20 years).

Of course, the role of the two is fundamentally different. High-end machine tools win "achievement" for customers, and high-end cars win "sense of achievement" for customers. “But as long as you win the 'achievement', you can naturally win the 'sense of accomplishment'!”

Inheritance is the foundation of innovation

“Without inheritance, there is no basis for innovation.” According to Chen Hu, in order to express respect for the historical giants of the precision machine tool industry, their company collects historically representative machine tool “works”, including coordinates like DIXI, American Moore. Coordinate grinding, Stutt's manual grinding machine, Makino manual milling machine.

This has two meanings. One is for the R&D department to pay respect and study. The second is the corporate culture that advocates learning. From the current high-end CNC machine tools in Europe and Japan, adhering to the traditional manufacturing spirit of excellence or the persistence of craftsmanship, it is still the corporate culture that many excellent companies adhere to. He hopes that Dalian Cod can become the inheritor of the new generation of classic precision machine tool manufacturing technology.

It is understood that Dalian Cod is focused on recruiting mature and experienced technicians and training their own technical workers team, and has resumed the workers' examinations in the factory.

In the workshop of Guangyang Production System, the workers have no fixed-time assessment of working hours, and how much can be done to the market. However, they have statistics on production efficiency, and the production system only needs to see whether the performance reflected by the statistics is sustainable.

This will inevitably affect the production cycle of a product, but Chen Hu insists that “sometimes spend more time convincing users to accept the delivery date, which is a hundred times stronger than letting users disappoint in quality.”

Therefore, they adhere to material testing and strict heat treatment processes in all machined parts; all machining requirements are maintained at the median tolerance; it is required to follow the traditional scraping process on key assembly joints to remove all possible removal of gaskets. Class adjustment link; requires more than double the internal control quality standard than the national standard.

Of course, if it is only these, there is almost no possibility to catch up with the pace of the first mover. After all, there is a gap in historical accumulation. Because Dalian Kede is a descendant of China's CNC machine tool industry, it only entered the CNC machine tool control system industry from the industrial automation industry in 2008, and then entered the CNC machine tool industry. Therefore, while insisting on the inheritance of precision machine tool manufacturing technology, they are also boldly innovating. The external performance is that the Chinese-made five-axis CNC system is first used in large quantities, and the torque motor is used as the machine tool rotation coordinate in the largest amount in China.

Only these two points, not to mention that at the time in the industry normality is maverick, even if it seems to be somewhat out of place in the moment. But why is this?

Chen Hu told China Industry News that compared to the traditional experience of Europe for hundreds of years, they did not have the technical basis for manufacturing precision gear drives and precision worm gears, which forced them to open up new technical routes. A successful case of a drive feature.

To this end, the company has invested a large amount of basic research in numerical control technology and direct drive technology, and has more than 100 patents related to it. Looking back now, this way has won the opportunity for Guangyang.

China Industry News reporter learned that they have already cooperated with a certain automobile company to test the servo motor, direct drive technology and system control to the automobile industry, and drive the four-wheel rotation by electricity. This way, not only is it saved. In the original car's complex transmission system, the wheels can swing 90 degrees left and right, so the car can also walk sideways. For vehicles such as missile launch vehicles, it can greatly increase maneuverability and off-road capability.

Today, Dalian Guangyang has become one of the few companies that use their own CNC systems, servo drives, motors and sensors to support their own CNC machine tools. With the extension of the industrial chain, the controversy caused by Dalian Guangyang has also followed.

Yu Dehai once said on different occasions that the company's technology can be transferred in different ways, but the effect is not significant. In the opinion of China Industry News reporters, their tirelessness is more like an ankle and evangelist in the Chinese machine tool industry, using their own actions to explore the direction of development.

Chen Hu also believes that China's industrialization process needs the progress of the national machine tool industry too much; China's large economy cannot be without its own CNC system; there are not 100 Dalian Guangyang and Dalian Cod in the Chinese CNC machine tool market.

●Reporter's notes

Also said Internet +

As a post-70, I am also thinking about "Internet +", which can bring improvements and changes to our business.

The first is the market demand. The most shallow impact is that the platform for interacting with the user in the business model can be upgraded to provide users with more customizable options.

Further, we are no longer providing a device product in isolation, the device is placed in a larger IoT system, the CNC machine tool is no longer an information island, the machine tool must be able to collect the underlying information, the device operating state, the operator Information and behavior, processed products entering and exiting the machine tool, and tool holders, the machine tool can transmit this information to the higher-level manufacturing system.

The domestic CNC system obviously has technical innate convenience in this respect. Due to the limitations of the single machine tool process capability, especially the process of hot and cold processing, and the principle of process separation of rough finishing, I don't think that a single machine tool needs to have autonomous intelligence in the short term. As a machine tool equipment supplier, we should have the ability to participate in the integration of larger manufacturing systems, until we have the ability to build intelligent production systems for our users.

On the other hand, Industry 4.0 will enhance social collaboration, including the machining of parts and components of machine tools, which may be dispersed into more specialized parts manufacturing systems.

It is foreseeable that the large and comprehensive model of the machine tool industry will gradually fade or even disappear in the future, but I think this will only be limited to the manufacture of parts and components, and even to the assembly of components. I don't think that high-precision machine tool assembly will be dispersed outside the machine tool factory, because the machine-owner's Know-how and intellectual property rights are also difficult to protect. The electromechanical coupling matching for the specific needs of users is also difficult to debug, and quality control is difficult to guarantee. The product loses its technical characteristics and advantages, and it also loses its high-end market positioning.

Of course, the general-purpose products with lower precision have already appeared in the trend of professional assembly, but this is not the format of high-end machine tools, and will soon fall into the "Red Sea."

Therefore, whether in product information integration or broader social collaborative manufacturing, we are required to pay more attention to the "standardization" strategy than ever before. GE is an outstanding representative of the US high-end manufacturing industry. Similarly, German Chancellor Angela Merkel came to China to talk about the standard of selling industry 4.0. This is the content that our country and our industry need most strategic thinking for Industry 4.0.

In the end, I am very fortunate that in the peak performance of high-end machine tool precision, it is not the chip that has the final say, nor the software has the final say, nor is it the capital to say the finale. With the "ingenuity" and "hard work", we still have the opportunity.

Angle Grinder

The angle grinder is a power tool used mainly for surface and circumference grinding (abrasive cutting or cut-off grinding) on various materials, but mainly metal. The mini angle grinders come with a speed of 10000RPM and 115/125mm disc diameters; large angle grinders are designed for heavy duty applications. They feature 180 or 230mm disc diameters and 1200 to 1500 watt.
