Smart Industrial Empire

"There is only 300 million working capital. If the current situation cannot be broken within half a year, the more machine tools the factory produces, the greater the factory's losses. The 300 million can only support half a year."

Yun Fei could only pretend not to see the surprise of the two old men.

He originally thought that he did not buy any equipment, but spent nearly 3000 million yuan just for the construction of infrastructure factories and residential areas. Some of the heavy-duty processing equipment bought back from the Soviet Union by Kamart was all spent on cards. Matt's Li Lu helped to pay for it.

If Li Lu's money is paid back now, Yunfei's Jiuyi Heavy Industry will not have a penny left on the books, and 300 million is not enough to pay Li Lu back.Perhaps Li Lu also knows the predicament Yunfei is facing now. It is probably because of Yunfei's help that he forced Yunfei to obtain the agency rights of the CNC lathes produced by Jiuyi Heavy Industry in the entire Pearl River Delta.

Now that Yunfei knows the plight of Jiuyi Heavy Industry, he really wants to hand over the agency rights of the Pearl River Delta for CNC lathes to Li Lu, but it seems too unkind to do so.

"Xiaoyun, we've been doing research on this for a lifetime, but in the end, we haven't produced any results. We're afraid we won't be able to complete the task you entrusted to us in a short time..." After hearing what Yun Fei said, Jiu When Yizhong was in such a predicament, the two elderly people agreed to Yunfei's request without hesitation, but for this research, especially in such a short period of time, they were not confident that they could come up with a preliminary design plan for a CNC milling machine.

"Sun Lao, Yun Lao, the CNC milling machine is actually very simple, the main reason is that it takes a lot of work on the spindle. The product we introduced to the market for the first time has a stroke of 630mm on the x-axis, 400mm on the y-axis, and 500mm on the z-axis; the maximum speed It can reach 6000 rpm. The rapid movement speed can reach 1500mm, the feed speed can reach [-]mm, and the workbench can bear [-] kg. The main shaft is driven by the synchronous toothed belt of the main shaft motor, but it is not possible to use a belt drive. A frequency converter is installed on the spindle motor to control the speed of the spindle..." Yunfei began to talk to the two about his expectations for the various parameters of the first CNC milling machine produced by Jiuyi Heavy Industry.

These parameters made the two old guys dumbfounded.

It's not that they are absolutely not asking for such parameters to be too low, but that they are too high for them.

Since Yunfei has specified the transmission method of the main shaft and pointed it out to them, and there is not much room for choice on the ball screw.Everything has to be designed by Xin Kaixing. In fact, they are mainly responsible for the transmission of the main shaft and the electrical aspects.

The Soviets have been working on it for a few months, and I believe they have completed the basic design. If only the most critical ones such as electrical control, hydraulic servo system, and spindle system are left, they should be able to complete the theoretical design if they work overtime.

Anyway, what Yunfei wants is to come up with the theoretical design, as for whether the more precise key components like the spindle can be made out by then.That was the matter of Yun Fei, the young boss.Although they have been engaged in the research of CNC machine tools for a lifetime, they understand better than anyone that the reason why China's CNC machine tools have not been produced for so many years is not only because there is no CNC system in the country.It is also because of the shortage of domestic materials and the defects in the processing of high-precision precision parts.

Whether it is a CNC milling machine or a machining center, the most important thing is the spindle.And precision bearings on the main shaft.China has a big gap with foreign countries in this regard, especially bearings.

The most advanced bearings abroad.It will never be sold to China, especially CNC grinding machines. The control abroad is even stricter than that of CNC machine tools.The CNC grinding machine is the most critical core equipment for the production of CNC cutting tools. If there is no grinding machine, it is impossible to process a sharp cutting edge for high-hardness alloys.

The knives currently produced in China are mainly yt, yw, and yg types of common welding blades in the traditional sense.Of course, front steel knives (white steel knives) of high-speed tool steel are also commonly used.Because the knives used by milling machines are not like those used by turning tools, as long as the knives are taken out, workers can sharpen them by themselves.

Ordinary milling cutters for milling planes or large steps are not a problem, but rod milling cutters for various complex cavities are not good, because there are several helical edges on the milling cutter, and a special grinder is required to grind the cutter Several cutting edges are ground before they can be used.In terms of tool grinding, China is taking the development path of special machines, but the price of a special tool grinding machine is simply not affordable by ordinary machine tool manufacturers, especially those thread grinders used for processing taps .

Even in the Dinosaur Cemented Carbide Factory, which specializes in the production of knives, and the Rongcheng Measuring Tool Factory, which has gradually emerged, the number of these precision machine tools is only in single digits, not to mention CNC.

If CNC machine tools want to have great development, it is necessary to continuously improve the production efficiency and production accuracy of CNC machine tools.This is not only the research on the machine tool itself, but also the research on CNC tools is the top priority.

Now that the two old fellows agreed, the worry in Yun Fei's heart did not abate in the slightest.

When you don't see the result, you will never be happy.

The two old guys still have a lot of things to explain to their apprentices and grandchildren, and told Yunfei that after they finished making arrangements here, they would go to Yunfei's general manager's office in the afternoon to find Yunfei.The sooner they invest in research, the sooner they can see the results. They don't want this factory with huge ambitions to be bankrupted by those villains at the very beginning.

The domestic numerical control technology is far away from foreign countries, and those large domestic machine tool manufacturers are still secretly delighted at the little bit of development they have achieved on ordinary machine tools.Sun Lin and Situ Heyun are sure that those machine tool manufacturers that have launched CNC lathes will not change significantly in a few years.

It is rare that some people in China even invest their wives in CNC machine tools. If they do not support it, they will not be able to be worthy of the industry they have devoted their entire lives to, and even more sorry for the motherland they have devoted their entire lives to.

After saying goodbye to the two old guys, Yun Fei took the freight elevator directly to the fourth floor where the Institute of Electronics under the control of Tanalia was located.

I really don't want the heads of my two most important technical departments to be Soviets, but there is no way to do this under the current domestic situation.Although the Soviets are now at the end of the road, if Yunfei is not worried that these Soviets will leave in large numbers in the future and run back to their country to produce CNC machine tools, it will be a disaster for him.

Natalia saw Yunfei, the boss of the department she was in charge of, came to her site and quickly ran to Yunfei.The research task assigned by the boss is about to achieve complete success, and now we are doing process design for mass industrial production, and have already tested the performance of these samples.

I don't know where the young boss got this knowledge. Anyway, according to the boss's prompt and the detailed design drawing given by the boss, they not only produced samples, but also designed several more Professional microcontroller.

"Boss, we will be able to complete the design of the production process immediately, and the theoretical design of the control system you entrusted to us is also coming to an end. Now we need experiments, and a large number of experiments can make our products more perfect. Our electronic workshop, what? When will it be put into production?" As soon as the boss came, Natalia asked the boss about the production of new products.

The production process they are designing now is only theoretically designed. To make the process more perfect, it is necessary to find the deficiencies in the process in the mass production process and continuously improve it.

"It's finished so soon?" Yun Fei was a little surprised.

Although Natalia and the others are only engaged in the industrial production process design of the 32-bit chips given by themselves, they are still responsible for improving the Long CNC system.

There are more than 30 people under Tanalia, and basically none of them have been in contact with the CNC system. Even if they have the most theoretical foundation in the CNC system, they also have the most detailed complete set of design drawings provided by Yunfei.Yunfei believes that this is not a problem they can solve in a short time.

"Aren't there conditions in the laboratory to produce samples of chips?" Yun Fei didn't know why this female electronic engineer from the Soviet Union cared so much about the industrial production of industrial control chips.

Even if they set up their own electronics factory for chip production in the future, they will not be allowed to go to the workshop.

These people, who had spent a lot of money to get them back from the Soviet Union, did not dare to treat them as the most low-level technicians and use them in the production workshop.The value of engineers lies in the development of new products, not as technicians in the production workshop.

"The quality of the chips produced by a single piece in the laboratory is too unstable, and now because of the shortage of raw materials, especially the shortage of monocrystalline silicon, we can't let go when we are conducting experiments..." Tanali Ya said to Yun Fei embarrassedly.

Although the laboratory provided by Yunfei is very simple, it can also carry out a lot of basic research. After all, the key equipment in the laboratory is shipped from their original research institute, and some of their original research institute There is no advanced equipment, so what they study every day is not only the research tasks assigned to them by Yunfei, but also some research projects when they were in the Soviet Union due to lack of raw materials and research conditions.

In particular, 32-bit industrial control chips were not available in the Soviet Union.The Soviet Union is not farther than China on the road of industrial control chips. (To be continued..)
