At the time of national orders, the military only symbolically gave orders for dozens of four-axis machining centers to Jiuyi heavy industry. Yunfei not only wanted to get more orders in the future, but also improved the accuracy level of the whole four-axis machining center of Jiuyi heavy industry. The standard reported to the military was that these four-axis machining centers contained automatic detection devices!
Now, for the four-axis machining centers whose technology has gradually matured, the production plan has been arranged. Some key parts with a long construction period have been rough machined, and many have even begun natural aging
In mass production, natural aging is very serious to the capital backlog of enterprises.
Even the rich and powerful enterprises like Jiuyi heavy industry dare not play like this.
The more precise the parts are, the longer the natural aging time will be.
However, in order to eliminate the machining stress caused by the machining process as much as possible, multiple heat treatments must be carried out.
In order to improve the accuracy and service life of parts and reduce the production cost, Jiuyi heavy industry not only adopts multiple heat treatments, but also carries out semi natural aging of these parts in artificial state. This is the aging method used by Jiuyi heavy industry to produce the guide rail of inclined bed CNC lathe and some other key components of precision CNC equipment.
"Xiao Yun, if they can''t complete the research, shall we accept their technology or..." Sun Lin, who is mainly responsible for the four-axis machining center project, knows the situation there.
The machining accuracy grade of their four-axis machining center is also 0.005mm, and the detection technology has such accuracy, which can be matched.
Yun Fei shook his head: "old sun, we can accept anything else under concession, but we can''t do it in the test. We have paid a lot of money for this technology. If the detection accuracy cannot be higher than our production accuracy, it is difficult to improve the production accuracy of our products. Once we make concessions now, I don''t know how many concessions we will make in the future! "
In terms of technical research, it can''t be almost enough.
They are almost the same, and others will be more similar. At that time, Jiuyi group will be fully surpassed by those domestic peers who rise to catch up.
Such a thing is something Yun Fei doesn''t want to see.
"The technology of our motorized spindle is still immature, so we''d better not use it for the time being? At that time, we gave them the maximum speed of 12000 rpm. Now our spindle can fully achieve it. There is no need to turn to the speed of 18000 RPM... "Although Sun Lin agrees with Yunfei''s idea of providing higher performance CNC equipment to the military, his technology is obviously immature. If we do so, It will affect the credibility of the whole company.
The military has always been the most valued customer of the 91 group.
They pay much more attention to the military than those private enterprises in China.
"If the technology of motorized spindle is not mature, don''t use it. Mr. Sun, now we are under great pressure from 91 heavy industry. If we can''t make our four axis machining center famous in a short time, we will be under even greater pressure after those foreign CNC equipment factories export five axis machining centers to China. Since we can''t take out the five axis machining center to compete with them in a short time, at least in the market of four axis machining center, we should occupy a huge market share, otherwise we will lose all the high-end market... "
Once the five axis machining center enters China, China''s CNC equipment will be downgraded again. Even if the precision grade produced by Jiuyi heavy industry is high-grade in China at present, 100% will be reduced to medium grade.
The four axis machining center they produce can be ranked at the lowest end of high-end equipment.
"Situ told me that it is very likely that Japanese companies will have five axis machining centers at our domestic international machine tool exhibition this year. Japan has been seeking to export to China, but it has not been approved by the government..."
The senior management of the whole Jiuyi group has such concerns.
The production technology of CNC equipment in China has developed too fast. The last thing we want to see is Japan.
Just as at the beginning, as soon as the two axis CNC lathe with independent intellectual property rights was developed by Jiuyi heavy industry, Japan began to export low-end CNC lathe manufacturing technology to China on a large scale; When Jiuyi heavy industry developed three-axis two linkage NC milling, they began to export machining centers and NC milling production technology to China on a large scale.
With the production technology of the four-axis machining center, Jiuyi heavy industry is most worried about Japan.
Because of geographical relations, China is their biggest market.
Before the emergence of Huadu CNC, a CNC system manufacturer, Japan''s FUNAC, Mitsubishi and other systems accounted for 70% of China''s CNC system market! After the emergence of the number of flowers, the number of numerical control systems in Japan has shrunk rapidly by less than 40%, while those in Europe and America have shrunk to less than 20%. With the rise of a large number of CNC equipment manufacturers in China in recent two years, the market share of Huashu has been further improved.
The loss of the numerical control system does not hurt the Japanese.
Even if the Chinese have a numerical control system, they can not produce high-precision numerical control equipment.
The profit of CNC system is far lower than that of CNC equipment. Especially in high-grade CNC equipment. The production cost of a four-axis machining center is only hundreds of thousands, but at least three million can be bought in China!
The profit of five axis is even more outrageous.
Chinese people''s CNC system is not good, mechatronics technology is not good, automatic control is not good, and even the most basic electronic and mechanical technology is not good!
Now, with the rise of Jiuyi heavy industry, the Japanese don''t think so.
They must completely stop the rise of Jiuyi heavy industry. Otherwise, once Jiuyi heavy industry has mastered the production technology of five axis machining center, they will lose the Chinese market.
The profits in the low-end market are too thin, and they give up on their own initiative; The profits in the mid-range market are not low, but with Jiuyi heavy industry, a Chinese national enterprise with a very good relationship with the government, and Jiuyi heavy industry also spreads its production technology to many production enterprises across the country, and the processing centers made by the Chinese themselves are constantly crowding out their market share
The main profit of Japanese CNC equipment manufacturers in mainland China now is the export of high-precision three axis machining centers and four axis machining centers to China. Now, with the manufacturing technology of 91 heavy industries, the Chinese mainland will definitely not hesitate to support the 91 heavy industries in order to support the national enterprises, even if the equipment produced by 91 heavy industries can not be compared with them.
In order to prevent the rapid approach of Jiuyi heavy industry to the five axis technology, we must seize China''s orders.
"Yes, it is very likely that not only Japan, but also European and American manufacturers may come to China with some of their five axis machining centers with low precision and release the blockade on the Chinese market. No country wants to see that China has its own five axis production capacity..." Yun Fei sighed.
"Shouldn''t it be so fast? When the Germans quietly bought four axles from us, it took several years to fully liberalize them! Moreover, their ultra-precision equipment is still under embargo against us. Take their four-axis CNC tool machines for example. After talking about our 91 materials for so many years, isn''t Dirk willing to sell them to us? " Sun Lin was a little surprised.
They only speculated that the Japanese would have a small amount of five axis Chinese exports, but they didn''t expect that Yun Fei''s speculation would be so bold.
"No one can tell what didn''t happen. After all, at the exhibition in 1995, the Ministry of machinery announced that we would start delivering four-axis machining centers to the military in 2008... No matter what they do, we must adhere to our own development direction and our research investment, otherwise, we can only look forward to the survival of leaders like the northeast first machine and the capital first machine... "
The slow wire cutting project presided over by Deng Lanqing had no support from the West Lake electric processing and acting Institute, so he had to explore it by himself. There had been no breakthrough, and the fully automatic flexible manufacturing system was only a semi-finished product.
The entire 91 Research Institute is only one step away, and it can soar to the sky.
But no one can tell how difficult this step is and how long it will take.
A breakthrough in technological research is urgent.
Hurry, there is no effect.
"Mr. Mellon, how''s our negotiation with Dirk''s four axis tool mill?" Yun Fei originally thought that it would be much easier for Mellon, an old man who has a lot of friendship with Dirk company, to negotiate to purchase from Germany four axis four linkage CNC grinding machines that are restricted from exporting to China in the Wassenaar agreement. However, he was wrong.
"Boss, there''s nothing I can do about it. The top management of Dirk company tends to export to us, but our government disagrees. In addition, the Japanese of wassena Supervision Committee keep a close eye on this, so... "Mellon shrugged and smiled bitterly when he heard Yun Fei''s question.
After arriving in China, he helped the 91 Research Institute order a lot of research instruments from Germany, and even many of them were instruments that were clearly prohibited from China in the Wassenaar agreement. For this reason, he was even warned by the German government.
If he didn''t have a 3% stake in the 91 group, he wouldn''t be able to get away so easily.
Foreigners simply do not know that the 91 research institute does not belong to the 91 group
They can''t understand many things in China.
"It''s all right. I''m just asking. After all, the production efficiency of our manual tool mill is too low... "Yun Fei knows that old man Mellon has paid for the whole group company. The equipment used for technical upgrading in the whole Jiuyi material factory is made by old man Mellon with his consulting team from Germany to China, and there are even three-axis CNC grinding machines.
Therefore, after the merger of wheat mobile phone into Jiuyi group, he did not reduce the shares of old man Mellon.
