Smart Industrial Empire

Yun Fei didn't know whether he was talking about the good heavy-duty CNC lathe made by Jiuyi Heavy Industry, which is mainly aimed at the military industry, or the price is good.

Such heavy equipment is not so much produced by Jiuyi Heavy Industry, as it is the CNC transformation of such heavy lathes by Jiuyi Heavy Industry.

Although even the transmission mechanism has been redesigned and modified, the price has a profit of hundreds of percent.Whether the old man understands this, Yunfei doesn't know, but the numerical control transformation of these heavy equipment is not an easy task.

Heavy-duty lathes are not as simple as the numerical control transformation of those small lathes, just replace the tool holder, replace the transmission mechanism, and then install a transmission in the circuit that controls the spindle speed and then connect it to the numerical control system.

The heavy-duty lathe is only the slide box and the tool holder part connected to the tool holder, and the weight is counted in tons!It is simply impossible for the ball screw used on ordinary CNC machine tools to drive a tool holder weighing hundreds of kilograms for heavy-duty cutting.

Besides, not only China, but even Germany, it is estimated that it is difficult to produce precision ball screws with a length of ten meters or 20 meters.Therefore, the transmission of such equipment cannot adopt the most common ball screw pair transmission mode of CNC machine tools, but uses a large DC stepping motor to drive the rack and pinion to transmit power. cutting.

The price of 200 million is already a very generous price.

If it is sold, it is very likely that the 200 million will become 200 million US dollars!

The value of CNC machine tools is not only high-end precision CNC machine tools, but also large and heavy equipment that most machine tool factories cannot produce. The price is quite considerable.

This is also the reason why some heavy equipment manufacturing plants can not only survive, but also have high profits.Research funding is even provided by clients.

Jiuyi Heavy Industry does not even have the production technology for a lathe with a rotation diameter of one meter. If it has not received the customer's request, it would not have conducted research in this area when it had not even produced a CNC machine tool with a rotation diameter of 600mm.

Research on rack and pinion transmission mechanism.It is one of the strategic research projects of Jiuyi Heavy Industry.Yunfei listened to Ren Zhiguo, who became the boss of Kmat, saying that the domestic aviation system was looking for foreign suppliers of heavy-duty bedroom CNC lathes with a diameter of 1.6 meters and a length of equipment guide rails of 20 meters, but they have not received any news.Only Germany and the United States have such equipment, and even the devil's Japan does not have the production technology for such super-large and heavy equipment!

There is ordinary lathe technology for producing such heavy equipment in China, and these technologies come from the Soviet Union!But it is not easy to produce CNC machine tools.

Anyone who knows missiles and large rockets knows that in order to comply with aerodynamics, the resistance encountered by missiles during flight is reduced.A long part of the head of the missile is used to install combat components and observation guidance components. The outside of the cabin is conical.

The processing of large cones is very difficult on ordinary lathes. Not only cannot the surface roughness after processing be guaranteed, but it is also very likely that when a small pallet is used to form a mechanically running oblique track to borrow the tool, it cannot be completely leveled. , which makes the rear processing cone surface not on the same plane as the front processing cone surface, which will cause some uncontrollable problems on the flight path of the missile.

"Mr. Deng, this is the test workshop of our three-axis machining center and four-axis machining center. These three-axis machining centers are working on the research of accuracy into three digits after the decimal point. As long as we can complete such a research, our CNC machining centers are fully able to compete with those foreign CNC manufacturers. Our cost is lower than theirs, and we are closer to the market, and the transportation cost is also very low." Sun Lin looked at the front and saw that these were being assembled or disassembled or Detect bare metal without a shroud installed.The old man who nodded from time to time explained.

"These guys are three-axis machining centers? Why are they different from what we saw in Huadu CNC?" When he first saw those ugly machines in the closed assembly workshop of Jiuyi Heavy Industry, the old man was very puzzled.

The machining centers he saw at Huadu CNC had a very high-tech feel, but now he saw that Jiuyi Heavy Industry didn't even have a shell.Equipment that is similar to ordinary machine tools is connected to a console with some wires on the outside. No matter how you look at it, it cannot correspond to those advanced equipment.

"Mr. Deng. We are just some semi-finished products used for testing, and the test places for each equipment are different. Some are used for tool positioning tests, some are used for machine tool displacement detection, and some are used for hydraulic and pneumatic tests. Wait, these are just a part of the processing center in a complete sense..." Sun Lin didn't care whether the old man could understand, and directly popped out a lot of professional terms.

"Oh!" The old man nodded. Although he didn't understand these terms, he didn't feel embarrassed at all.

If you don't understand, ask!

"It's not easy. I didn't expect that these high-tech equipment would go through so many tests!" An old man behind the old man with two shining golden lights sighed.

"Is there any finished product for my old man Zhang Zhang to see? Last time in Huadu NC, I didn't have much time, so I didn't take a closer look. You kid won't keep it a secret from me?" The old man asked Sun Lin and then said to Yun Fei He said something that made Yun Fei almost die.

"How can it be! Mr. Deng, even if I keep a secret from people all over the world, I can't keep it from you, can I? At least we are fellow villagers?" Seeing the people behind the old man, Yun Fei had a playful look on his face. Looking at him, his face immediately turned red.

The last time Li Shang of the Commission of Science, Technology and Industry for National Defense inspected the work of Jiuyi Heavy Industry, he did not enter any of the laboratories of Jiuyi Heavy Industry that had nothing to do with the military.Not to mention those officials from the State-owned Assets Supervision and Administration Commission and the Development and Reform Commission, but they didn't even enter the gate of the experimental building!

When they arrived at Jiuyi Heavy Industry, they were still rejected. How could they be happy?Therefore, many people in the central government know that the boss of Jiuyi Heavy Industry is petty!

"These products are mainly developed for domestic users and are in line with the usage habits of Chinese people. Even the operation panel has been improved by the relevant departments in our research laboratory." Walking to the enclosed area used for the machining test of the three-axis machining center and some key parts of the four-axis machining center, Yun Fei introduced it to the old man.

"Don't just focus on our domestic market. If a company wants to grow bigger and stronger, it must enter the international market and be recognized by users in the international market!" The old man said that China's growth rate is getting faster and faster every year. More than 18.00% of the products in China's export trade are low-end light industrial supplies and raw materials that have only been roughly processed or even not processed.

When will China be able to provide a large number of high-tech products to the international market like the developed countries in the United States and Europe, can it be regarded as developed.

"Mr. Deng, please rest assured that our products will compete with those foreign CNC machine tool manufacturers in the international market sooner or later!" Yun Fei answered the old man seriously when he heard the old man's request.

If you want to sell CNC machine tools to the market of those powerful countries that produce CNC machine tools, their technology will be recognized by the outside world.

"This matter is difficult!" The old man said to Yun Fei equally seriously.

"No matter how difficult it is, we have to do it! My generation can't do it, and our next generation will work hard in this direction! Your heart is so strong that it cannot be penetrated. You have never been like a widow and a weak son. Even if I die, there will be no children left." ; Sons beget grandsons, grandchildren beget sons; sons have sons, sons have grandchildren; sons and grandchildren are inexhaustible! Sooner or later, we will inherit the glory of our ancestors and stand on top of the world again!" Yun Fei used Beishan Yugong answered Hequ Zhisou's words to express to the old man his wish to make the company bigger and stronger.

"Very good! Work hard. Young man, the world used to be ours, now it is yours, and it will still be yours in the future!" The old man nodded with satisfaction.

It's not terrible to be behind, but the terrible thing is that you don't know how to catch up when you are behind!

Hundreds of years ago, China was the number one technological power in the world.Then, from the sixteenth century onwards.China gradually declined until the founding of New China, and the country was under the leadership of the Communist Party of China.Only then did we start to work hard, and although we took a lot of detours in the process, we almost dragged China into dire straits because we underestimated the paper tiger-like imperialism of the United States and Britain.

But these pains are normal.

If the country wants to fully catch up with those countries that have surpassed China for decades or even hundreds of years, it cannot follow the old path of those countries, but must follow China's own path.

This road is a shortcut.

Often, on the road to a strong country, there are no shortcuts.If you want to take a shortcut, you must remove the thorns and obstacles on the shortcut one by one.

The two experimental areas are only separated by a wall, but the investment and research inside are very different.

In the research laboratory of the four-axis machining center, there are many research equipment bought from Germany at a high price. Yunfei doesn't know the performance of these equipment, but he only knows that the price is too expensive.If it weren't for Kmart's channels for so many years, many things would basically be impossible to get!

The area next to the door is the area where the three-axis machining center is used for processing experiments. It is in a deeper area than the research on the rotary table of the four-axis machining center, the research on the spindle, the tool positioning of the tool magazine, and other mechanical aspects. in.

Many times, whether it is Wu Zhongda or Ni Lishuang, many people are talking about Yun Fei's affairs in this regard. (To be continued..)

ps: Thanks to Tianhai Xiangyun, Sigh‖Sigh, and Gangwan for their great rewards.

Thanks to wzhtc, Tunren Tudao, Xiaoshouzhan, who can see Tianchi Mountain, and other big ones who can't see the gourd but voted for the monthly ticket.

Yesterday afternoon, many projects in the company needed to be delivered. Last night, the whole workshop was rushing to work, and the gourds were helping in the workshop. They were busy until after eleven o'clock, and there was no time to code.

Starting this month, Hulu is going to hit the full attendance of [-] yuan. It is initially estimated that the update volume will be updated three times a day, and [-] the next day, [-] cycles a month.
