Chapter 383

Yun Fei defends this and that all day, which makes people feel insecure.

It seems that this is living in the wind and rain.

But where do they know that this society is not as beautiful as it seems, and they don't know many dirty things hidden in the dark.

For example, Yun Fei guarded against some of his technologies of September 1 heavy industry, even people from national ministries and commissions, and he didn't know what he was guarding against.

They don't know, but Yunfei absolutely knows that few of the people who are seen in those parts have clean hips. Many of them come from large families in China. Their families, or those who support them, have a lot of industries. It is often to invest in which industry makes money.

Ye xuanmei made it particularly clear to Yun Fei that even the children of big families in the capital have a morbid enthusiasm for those high-tech companies, not to mention the NC machine tool industry related to national defense and has a wide market in the private market.

The reason why Yunfei has a sense of prevention against everyone, especially those so-called superior leaders, is because he has received some mother's education.

In the end, many folk traditional handicrafts in China have been patented by the devil country. The mysteries handed down by our ancestors have been sold out by those officials with good face!

Cloisonne and gold foil manufacturing are all mysteries handed down by China's ancestors, but they let the Japanese occupy the national market.

Do the Japanese really have such technology? If they can study it, they still need to import a lot from China?

As a result, the government leaders who treated the Japanese who came to visit as their ancestors ordered that the factory must not hide their secrets and carefully explain the production process and some key technologies to customers. Just to prove the craftsmanship of China's ancestors!

The Japanese just visited and investigated, got detailed manufacturing technology, and invested in research. It didn't take long to get out what they had never studied successfully before!

Few Chinese officials, especially those in this era, know the sense of confidentiality!

They simply forgot the rules of their ancestors and didn't spread a lot of things!

Although the old ancestors' practice has made many secrets that have not been passed down into history and disappeared, at least other countries and ethnic societies will not use these technologies to attack domestic manufacturers.

For the production technology of Jiuyi heavy industry, those CNC machine tools abroad don't look at it at all. Of course, this is only in CNC machine tools.

In foreign countries, when 16 industrial control chips are still being studied and 32 are still conducting theoretical research, 91 heavy industry has long used this technology mature and launched an impact on the higher 64 public chips! If these things are revealed by officials who do not know the importance and in order to earn face, the only thing that Jiuyi heavy industry can surpass those countries abroad may not get the slightest benefit.

With the scientific research technology of foreign large companies with deep accumulation, it is easy to solve the technical problems that they can't solve for a long time in a short time. Especially in the face of life and death! The chip of 91 heavy industry can directly eliminate the 16 bit chip that has been studied by foreign countries for more than ten years and a lot of money!

"Mr. Deng, this is the machining tool library we use for general assembly test and machining test. Due to technical and material reasons, only 16 cutters can be stored in the tool magazine of our first generation three-axis machining center, which can fully meet the use of general products. " These machining centers are still not equipped with external shields, but they look more sci-fi modern.

The machine with metallic luster, the manipulator that constantly changes the tool automatically, the workbench that continuously moves back and forth, left and right under the control of the NC program, and the machining center that moves up and down quickly and often linkage three axes make the wrinkles on the old man's face more obvious.

"How long will it take for your machining center to fully test successfully?" The old man could only watch the excitement, but when he saw that there was no one to operate several automatic machine tools, he asked Yun Fei.

If all factories use such equipment, the gap of skilled workers who have been perplexing China's economic development will no longer be a problem in front of these equipment that can automatically process complex and high-precision parts.

Two years ago, when the old man visited the south, almost every local official complained about the lack of people!

Especially the lack of researchers who have mastered rich theories and senior skilled workers with skilled technology and rich experience!

The scarcity of talents restricts the development of many places.

The state has long been discussing the need to liberalize the monopoly on talents and expand the enrollment scale of colleges and universities. It is estimated that the dust will settle soon.

This alone is not enough.

Skilled workers are the most valuable talents in a country.

Equipment is a factor. On the surface, it is the most important thing, but talent is the most critical factor. In the precision equipment, without the operation of senior skilled workers, it can not play its maximum value.

Take the most common three-axis linkage machining center as an example. If you don't have rich machining experience, you can only make some conventional products. Those high-level precision and complex products with strict requirements for operation technology have strict requirements not only in clamping mode, but also in the processing process.

For example, in the processing of thin-walled parts, as long as the selection of the three cutting elements is unreasonable, it is easy to deform the processed products. Especially when processing aluminum, stainless steel, red copper, titanium alloy and other materials with very large plastic deformation, even very skilled technicians can not process high-precision products that meet the design requirements without the guidance of equally experienced process engineers.

"Er..." Yun Fei saw the old man's expectant eyes, but he didn't know how to answer.

If only according to the use requirements of most users in China, the machining center of Jiuyi heavy industry has completed the research and experiment.

If we follow the use requirements of some precision parts with high machining accuracy, the research in this aspect of Jiuyi heavy industry is still far from enough. At least, for many aerospace parts, the accuracy of processing equipment is required to ensure that the theoretical processing accuracy is less than 0.001mm.

Don't look at the difference of at least one digit after the decimal point, but the difficulty is not only doubled.

"Our processing center has higher processing accuracy than many products exported from abroad to China. At least, we have realized the real three-axis linkage. Due to the foreign technical blockade against China, most of the processing centers exported in the past few years only have the function of automatic tool change, which can only realize three-axis and two linkage. When machining some complex special-shaped surfaces, they can only use the means of profiling processing to obtain the approximate part shape, and there is no way to guarantee the machining accuracy. " Sun Lin explained to the old man.

If the products of Jiuyi heavy industry are not under too much external pressure, coupled with the insufficient production capacity of the factory, they are likely to face the pressure of CNC machine tool manufacturers all over the world as soon as they are listed.

Therefore, when he did not fully form his own advantages, Sun Lin also supported Yunfei's decision not to be listed for the time being.

"How much is the production cost of your processing center?" The lieutenant general with two Venus on his shoulder asked sun Lin.

"It depends on the model. If it is the most common jy850 with 800mm X-axis travel, 500mm Y-axis travel and 550mm z-axis travel, the production cost is about 380000; The price of jy1080 is about 430000 for X-axis travel 1000mm, Y-axis travel 600mm and z-axis travel 650mm; The x-axis travel is 1200mm, the y-axis travel is 800mm, and the z-axis travel is 750mm. The cost of jy1280 will cost more than 500000... "Sun Lin directly quoted the price regardless of whether these people could understand this or not.

Of course, these prices are only a preliminary estimate based on the number of 300 units produced and sold a year, and they also include tens of millions of research funds.

Similarly, Sun Lin also reported a lot of moisture in these prices.

People who can travel with the elderly are either from the Ministry of defense or the logistics equipment headquarters. Yunfei has long listed them as the most important potential customers of Jiuyi heavy industry. Although Sun Lin knows that the military is short of money, the biggest driving force for Yunfei to invest a lot of research funds in CNC machine tools is to make money. If the military purchases and has no profit, the boy will not invest money here.

The more in-depth research on CNC machine tools, the more research funds are needed!

There will be no words in "...". He had no idea what Sun Lin said.

Lieutenant general has automatically ignored the production cost in Sun Lin's words, and he recognized the price!

"This one is the jy850 machining center studied by our factory. Next to it are jy1080 and jy1280..." Yun Fei saw the lieutenant general's face with a puzzled look, pointed to several machine tools running automatically on one side and introduced them to the delegation.

There are many potential customers here!

Few of these people understand the model, but many of them have dealt with these high-grade goods and can compare them with foreign imported machining centers according to the size of machine tools. Although these machining centers without shell look much smaller and ugly than those imported machine tools, it does not prove that they do not understand these things.

People who don't understand can't follow the old man to visit such high-tech enterprises! Especially for the boy who has to keep everything confidential to visit his factory.
