Smart Industrial Empire

ps: Thank you 25 Degree Sunshine 2 for your tip, and thank you hywbj123 and kun111 for your two monthly tickets. ,

Last night, I got off work at [-] o'clock in the morning. I got off work too late. I said I was typing this afternoon, but I slept soundly. The boss informed Hulu to work overtime at the company this afternoon. The entire industrial area has power cuts these days, and a lot of work is piled up...

I don't know if it can be completed at [-] today, but Hulu will try its best to complete it. ,

"Come here, you must come here!" Upon hearing Yun Fei's words, Liu Cheng replied without thinking.

This is the equipment, not to mention the large castings used to process CNC milling or machining centers, even the basic large castings used to process ordinary milling windows, the efficiency is much better than that of the company's technicians.

The improvement of processing efficiency will inevitably reduce the production cost of machine tools.

The lower the cost and the better the quality of the equipment, the stronger the competitiveness in a market-oriented environment.

"What is the precision of the CNC gantry milling you designed for various large castings? What is the approximate annual production capacity?" Since you want to buy it, you must first understand the performance of these products, after all, it is related to many things. something.

At a time when the sales of their products are not very good, it is definitely not possible to buy back a bunch of equipment that can only be placed there as a decoration.

Although the state pays, it can't be too extravagant and wasteful, right?

"Our gantry milling is within the working range of three meters. The designed processing flatness is within 0.05mm, the straightness is 0.07mm, and the repeat positioning accuracy is 0.05mm. However, according to the current processing level and technical conditions, the final finished product is The flatness can only reach 0.08mm, and the straightness is 0.1mm. The repeat positioning accuracy is 0.06 to 0.07mm..." Yunfei is a little embarrassed. Some foreign companies that produce heavy precision equipment produce such medium-sized gantry milling. The actual processing accuracy is They are all higher than their design accuracy.

Heavy equipment is not as capable of high precision as smaller equipment.

The precision indicators and standards of small equipment are generally in the order of 0.01mm.

The precision indicators and technical standards of heavy equipment are based on 0.1mm.

If the CNC gantry milling designed and developed by Jiuyi Heavy Industry can achieve the precision he said, it will already be able to enter the category of precision equipment.

Of course, these parameters are not mentioned by Yun.They are all theoretically designed performance and the performance that can be achieved in theory. In the end, the accuracy that the factory-made equipment can achieve will definitely be different from the data that Yunfei said.

Of course, manufacturers who use these devices will be psychologically prepared.

Even the best foreign manufacturers cannot achieve [-]% accuracy of theoretical design.

The processing accuracy of the equipment involves many aspects, such as the material's own performance.The accuracy range of processing, the realization of assembly technology, the performance of control system, and even the temperature change around the equipment.The flatness of the ground and so on.

It is also because of this that CNC machine windows can measure the industrial level of a country.

"Can it achieve such a high precision?" Zhu Feng, who has been immersed in the mechanical technology industry for more than half his life, expressed some disbelief.

He believes that there is a lot of water in Yunfei's words.

"Of course, this is only based on our experience in producing other equipment. The inferred data, what kind of accuracy can be achieved in the end, must wait for our research work to be completed. We will continue to improve and strive to achieve our design within five years. Accuracy requirements..." Sun Lin was very dissatisfied with Zhu Feng's suspicion.

These data are gathered from the best engineers and technicians of NHI and Jiuyi Heavy Industry using the most mature technologies of both parties, and after half a year of design, they are deduced based on the experimental data on site!

Capital Yiji can't produce it by itself, and even suspects that others can't produce it!

"Even if it is a little worse than the actual accuracy, this accuracy range can meet the finishing requirements of most domestic products. This accuracy is almost higher than the accuracy of the parts processed by the best ordinary precision equipment we use now... ..." As the earliest ally of Jiuyi Heavy Industry, Harbin Heavy Industry was the first to place an order for [-] units.

These CNC gantry milling machines are used for the final semi-finishing of Jiuyi Heavy Industry's OEM products, which not only have high efficiency and guaranteed accuracy, but also can control the processing dimensions of these important parts to be consistent. The processing procedure has a lot of benefits.

"Yes, the production efficiency of this is much higher than that of the ordinary equipment we are using now, especially the ability to gather many processes together, and it saves a lot of time just for the preparation of various clamping ..." A tall, thin old man with glasses listened to Pan Zhigao's words, looked at the CNC gantry miller in front of him, which was automatically running dry, and nodded.

All kinds of large and heavy parts need a lot of time to be clamped and aligned before processing.

Before there were large-scale and heavy-duty CNC processing equipment, each process was scattered, and each large or heavy part would go through processes such as planing, milling, boring, and clamping from the blank to the finished product. Specially formulated electrical processing procedures.

Each process requires an alignment and clamping, which makes the actual processing time of these large parts not even as long as the preparation time.

"Of course, in this way, all the processes that need to be processed on one surface are concentrated in one process. How can this not improve the accuracy and efficiency? We only have a quota of six machines for the second machine in the capital. Mr. Yun, you will not accept the order because it is too small? "Capital No. [-] Machinery is also a company that produces various machinery and equipment, but they are not as important as Capital One.

Even if most of the important state-owned enterprises' technology and equipment are intensively updated this time, the amount of capital and heavy equipment exceeds [-], and they only have six!

"How could it be, Mr. Zhao, even if we take your company's order, at least the delivery will start in the second half of next year. You only have such a small quota, don't you keep it for purchasing high-precision equipment imported from abroad?" Yun Fei was very sympathetic to the Capital Second Machine.

Although they make most of the common equipment.But the level of technology, there is really no way to compare with Capital Yiji.Otherwise, Yunfei would have directly asked them to cooperate.

Zhao Mingzhang of the Capital Second Machinery is still a very capable factory director. He was just in his early 40s and was appointed as the factory director of the Capital Second Machinery. The factory turned losses into profits, and their newly developed tool milling and small turret milling, although the rigidity is poor.However, for the processing of relatively soft materials such as aluminum parts and the finishing of steel parts, the precision effect is much higher than that of ordinary milling window processing.

Well received by market users.

If this is not the case, it is estimated that there will be no such thing as their capital's second machine in this centralized national procurement.

"In addition to the higher price, the accuracy of foreign equipment is not very good. In China, we only buy second-hand mobile phones scrapped by others and garbage machine tools produced by others. Why should we accept that foreign style?" Zhao Mingzhang said.Immediately, the leaders of the various ministries and commissions of the country who were watching Jiuyi Heavy Industry's experimental CNC gantry milling machine with great interest, automatically running into the gap between the guide rail and the gantry column under the control of the program suddenly became ugly.

These leaders have always advocated the purchase of imported equipment from abroad.

In their eyes, imported CNC equipment.It is the real high-precision CNC equipment.

"Let's go and see the site where we are researching the four-axis machining center..." The CNC gantry milling here is almost done. Whether to place an order or not, these bigwigs can't make up their minds for a while, anyway, they not only need to discuss internally .Finally, you have to go through the above approval to determine the quantity to buy.

After all, few people here are willing to spend all the purchase quotas of large equipment on Jiuyi Heavy Industry like Capital No. [-] Machinery.

And in the end, even Yunfei didn't show up.For the purchase of these heavy equipment, Yang Qing will also lobby his direct leaders. Only Jiuyi Heavy Industry's gantry-style machining center sells more, and they, the cooperative manufacturers responsible for most of the mechanical parts production, can get bigger profits.

He cares more about this matter than anyone else.

Of course, the bosses of various companies who have received the national heavy equipment purchase order quota come to Jiuyi Heavy Industry for field inspections, which is also the function of his up and down operations.

It has nothing to do with Yun Fei from Jiuyi Heavy Industry.

Yunfei just invited the leaders of various ministries and commissions to visit the factory. Unexpectedly, before the final trip, there were new changes on the above. In order to expand the independent management rights of the Ministry of Industry and the Ministry of Machinery and other state-owned units, the purchasing country this time is only Guidance and group procurement are in principle chosen by each enterprise independently, and the leaders of the national ministries and commissions are only responsible for collectively negotiating prices.

"Here is the four-axis machining center that we developed to imitate the German EP6, which can convert the spindle from vertical to horizontal. We have adopted most of the design ideas of the Germans. Most of the key technologies in it cannot be copied at all. You have to do your own research..." Strictly speaking, this is the first time that the research area of ​​the four-axis machining center is open to visiting groups.

This project cost Jiuyi Heavy Industry more than half of the research and development funds invested in CNC machine tools.

In the earliest sense, it should be before Jiuyi Heavy Industry has started to build a factory. Yunfei proposed to install a simple rotary table driven by a pmc control module on the three-axis machining center to form a simple four-axis like the fourth axis. , It has been more than four years, but there has not been much breakthrough progress.

The four-axis four-linkage is the factor that has always limited this project.

In this regard, Yunfei has nothing to do.

Although he has seen many four-axis home centers, and there are also German prototypes for them to disassemble, but there are some things that simply do not design their own products according to other people's products, and then assemble them.

"This project has taken four years from the end of [-] to the present, and has cost over [-] million yuan. However, due to various reasons, there has not been much breakthrough progress. The most critical technology is how to realize four-axis linkage processing. The four-axis three-linkage has been solved now, but the four-axis four-linkage is still not ideal..." Sun Lin introduced the research progress of Jiuyi Heavy Industry's four-axis machining center to the disappointed crowd.

If it wasn't for Yun Feifei's pursuit of the most high-end four-axis four-linkage machine tool capable of vertical and horizontal conversion, with the simple four-axis technical reserve, the four-axis machining center produced by Jiuyi Heavy Industry should have been able to be put into mass production up.

Although it is only the lowest-level four-axis three-linkage machine tool that is not much more advanced than those simple four-axis machines, but because the fourth axis and the xy two moving axes are integrated, the technology in the middle can be regarded as the first-class in China. .

"Mr. Sun, when will your company's four-axis be mass-produced?" For four-axis machining centers, it is especially important for companies that manufacture precision machine windows.

"According to the current progress, it will take about ten to fifteen months for the research to be completed, and then the level of accuracy will be improved to reach the RP6 of the Germans or higher than them. It is estimated that it will take at least three years, and The output of such advanced equipment will not be too high..." Sun Lin said helplessly.

For the four-axis project team with only one prototype for disassembly research, this thing is more than two or three times more difficult than the technology of the three-axis machining center!

"Then will your company accept the order now? Our Capital No. [-] Machine wants to place an order for ten four-axis machines right now, no matter what your price is!" Zhao Mingzhang said firmly.

When other people heard what Zhao Mingzhang said, they couldn't help expressing their views, especially companies like Capital Yiji and Northeast Yiji who wanted to obtain the technology they urgently needed from Jiuyi Heavy Industry, and they all expressed to Yunfei that they were urgently needed. Want to order Jiuyi Heavy Industry four-axis machining center...

....................................

This on-site visit is actually an on-site order meeting. Not only the bosses from various parts of the central government came, but also some factory directors and engineers from various heavy machinery and equipment companies who can call the shots.

In terms of the price of CNC gantry milling machines, Yunfei didn't charge randomly like those heavy CNC machines, and only offered a price of 380 million yuan per machine!

For this item alone, 130 intentional orders for two units were received on site.

This made Yang Qing, the director of the Northern Heavy Industry Factory, extremely excited.

Although Jiuyi Heavy Industry takes the bulk of the CNC gantry milling profits, Northern Heavy Industry, which produces mechanical parts, has also received a contract of more than [-] million yuan!

This is the largest order that NHI has received so far under the market economy system.

And all of this was brought to him by Jiuyi Heavy Industry, a private enterprise that he didn't like at all.

Jiuyi Heavy Industry has not yet successfully developed a four-axis machining center that imitates the German Dirk ep6. In the absence of physical objects and reliable technical means, it has also received orders for more than [-] units, but the delivery date is Went after three years! (To be continued..)
