199 Yunfei is not a requirement for CNC milling machines
"There's only three million in liquidity. If you can't break the current situation in half a year, the more machine tools the factory produces, the greater the loss of the factory, and the three million can only support half a year. ”
For the surprise of the two old people, Yun Fei could only pretend not to see it.
He originally thought that he would not buy equipment, but only spent nearly 30 million yuan on the construction of infrastructure factories and residential communities, and some of the heavy processing equipment that Kamat helped to get back from the Soviet Union, the funds were all paid in advance by Li Lu of Kamat.
If Li Lu's money is repaid now, Yunfei's Jiuyi Heavy Industry will not have a penny left on the books, and three million will not be enough to repay Li Lu at all. Perhaps Li Lu also knows the dilemma that Yun Fei is facing now, and forced Yun Fei to have the agency of the CNC lathes produced by Jiuyi Heavy Industry in the entire Pearl River Delta, which is estimated to be out of help to Yun Fei.
Now Yun Feizhi has explained the predicament of his Jiuyi Heavy Industry, and he really wants to hand over the Pearl River Delta agency of CNC lathes to Li Lu, but this is too unkind.
"Xiaoyunna, we have been engaged in this research for a lifetime, but in the end, there are no research results, we are afraid that we will not be able to complete the task you give us in a short time......" Hearing Yun Fei's 91 Heavy Industry in such a predicament, the two old men agreed to Yun Fei's request without hesitation, but for this research, especially in such a short time, they did not have the confidence to come up with a preliminary design plan for a CNC milling machine.
"Sun Lao, Yun Lao, CNC milling machine is actually very simple, the main thing is that the spindle needs to spend a little effort, we first introduced the product to the market, X-axis travel 630mm, Y-axis travel 400mm, Z-axis travel 500mm; The maximum speed is 5,000 rpm. The fast moving speed can reach 6000mm/min, the feed speed is 1500mm/min, and the worktable can bear 500 kg. The spindle we use the spindle motor synchronous toothed belt drive, is not good, the belt drive, the spindle motor is equipped with a frequency converter to control the speed of the spindle...... "Yun Fei began to gush to the two of them about their expectations for the various parameters of the first CNC milling machine produced by Jiuyi Heavy Industry.
Hearing these parameters, the two old guys were dumbfounded.
It's not that they don't require such parameters to be too low, but that for them these parameters are too high.
Since Yun Fei has pointed out the spindle transmission mode to them, there is not much room for choice in the ball screw. Everything has to be designed by Xin Kaixing, who is actually mainly responsible for the transmission of the spindle and the electrical aspect.
The Soviets have been working on it for several months, and believe that they have completed the theoretical design if they only have the most critical ones such as electrical control, hydraulic servo system, and spindle system left.
Anyway, what Yun Fei requires is to get the theoretical design out, as for whether the more precise key components like the spindle can be made at that time. That's the matter of Yun Fei, the young boss. Although they have been engaged in a lifetime of CNC machine tool research, they understand better than anyone that the reason why China's CNC machine tools have not been able to come out for so many years is not only because there is no CNC system in China. It is also because of the lack of materials in China, as well as 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 spindle. In this regard, China has a big gap with foreign countries, especially bearings.
The most advanced bearings abroad. It will not be sold to China at all, especially CNC grinding machines, and foreign controls are even more severe than those controlled by CNC machine tools. CNC grinding machine is the most critical core equipment for the production of CNC tools, high-hardness alloys, if there is no grinding machine, it is impossible to process a sharp edge.
The knives produced in China are mainly ordinary welding blades in the traditional sense, and three types of blades are used: YT, YW and YG. Of course, the blade steel knife (white steel knife) of high-speed tool steel is also more commonly used. Because the tools used in the milling machine are not like the tools used for turning tools, as long as the blade is made, the worker can sharpen it himself.
The ordinary milling cutter used to mill the plane or large step is not a problem, but the rod milling cutter used to carry out various complex cavities is not good, because the milling cutter has several spiral edges on it, and a special grinding machine must be used to grind out several cutting edges of the tool. In terms of tool grinding, China is taking the development path of special machines, but a special tool grinder, the price, is not at all affordable by ordinary machine tool manufacturers, especially those used to process the thread grinding machine of taps.
It is now in the dinosaur cemented carbide factory, which is now gradually rising, specializing in the production of cutting tools, and the Rongcheng measuring tool factory, which produces measuring tools, has only a single digit number of these precision machine tools, not to mention the numerical control.
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 from the machine tool itself, the research of CNC tools, is also the top priority.
Since the two old guys agreed, the worry in Yun Fei's heart did not weaken in the slightest.
When you don't see the results, you can never be happy.
The two old guys still have a lot of things to explain to their apprentices and grandchildren, and tell Yun Fei that after they finish arranging here, they will go to Yun Fei's general manager's office to find Yun Fei in the afternoon. The sooner they put in the research, the sooner they could see the results, and they didn't want the boss's hugely ambitious factory to be bankrupted by those villains at the beginning.
The domestic CNC technology has been thrown away from abroad, and the large domestic machine tool manufacturers are still rejoicing in the development of ordinary machine tools for their own achievements. Sun Lin and Situ Heyun are sure that the machine tool manufacturers that have now launched CNC lathes will not change much in a few years.
It is rare that someone in China even has his wife invested in CNC machine tools, if they do not support, they will not be able to be worthy of the industry they have paid for a lifetime, and they are sorry for the fact that they have paid for a lifetime and loved the motherland for a lifetime.
After Yun Fei said goodbye to the two old guys, he took the freight elevator directly to the fourth floor where the electronics research institute under Tanalia's control was located.
I really don't want the heads of my two most important technical departments to be Soviets, but there is nothing to be done about the current situation in China. Although the Soviets are now at the end of their rope, it would be a disaster for him to say that Yun Fei is not worried that these Soviets will leave in large numbers in the future and return to their countries to produce CNC machine tools.
Natalia saw that Yun Fei, the boss of the department she was in charge of, had arrived at her own territory and quickly ran in front of Yun Fei. The research task assigned by the boss is about to achieve complete success, and now the process design of mass industrial production is being done, and the performance of these samples has been tested.
I don't know where the young boss learned this knowledge, anyway, according to the boss's prompts, as well as the detailed design drawings given by the boss, they not only made samples, but also designed several more professional single-chip microcomputers.
"Boss, we will be able to complete the design of the production process immediately, and the theoretical design of the control system you handed over to us has also come to an end, and now we need to test and test, a lot of experiments to make our products more perfect. When will our electronics workshop 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, and in order to make the process more perfect, it is necessary to find the deficiencies in the process of mass production and continuously improve it.
"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 chip given by themselves, they are still responsible for improving the dragon CNC system.
There are more than 30 people under Tanalia, basically no one has ever touched the CNC system, even if it has the most theoretical foundation in the CNC system, and it also has the most detailed set of design drawings provided by Yun Fei. Yun Fei believes that this is not a problem that they can solve in a short time.
"Isn't there a laboratory that can 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 he later established an electronics factory to produce chips, he would not let them go to the workshop.
These people, who had spent a lot of money to get back from the Soviet Union, did not dare to use them in the production workshop as the lowest level of technicians. The value of an engineer is in the development of new products, not in the production workshop to be a technician.
"The quality of the chips produced in 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 of our hands and ......feet when we conduct test tests," Tanalia said to Yun Fei embarrassedly.
After all, the key equipment in the laboratory was transported from their original research institute, and there were some equipment that they did not have in their original research institute, so what they studied every day was not only the research tasks given to them by Yun Fei, but also some research projects that they had in the Soviet Union because of the lack of raw materials and research conditions.
In particular, 32-bit industrial control chips, in the Soviet Union, there were also none. The Soviet Union is not further on the road of industrial control chips than China. (To be continued......)
