I had a whole morning meeting with the foreign sales staff in the factory, but I didn't get any effective advice, and I didn't even know the production scale of those factories. It is only known that those who have lost their souls to the Chinese market not only have a large number of CNC milling machines, but also a lot of CNC machining centers with low machining accuracy.

The most painful thing for Yun Fei is that these Taiwanese-funded enterprises have now begun to focus on the CNC lathe market in Chinese mainland.

Shouldn't they be focusing on the Chinese market for 3-axis and 4-axis machining centers?

Fortunately, these salespeople had already inquired about the prices of the equipment of those Taiwanese-funded enterprises before they came back.

Perhaps they think that their products are higher than the technical content of Chinese manufacturers, and the machining accuracy is even a little worse than the accuracy of the CNC lathes of Jiuyi Heavy Industry, and the price is actually more expensive than that of 91 Heavy Industry.

Jiuyi Heavy Industry now has less than 30 CNC milling machines on the market every month, and the machining center is still waiting for the final assembly after the test is completed in the assembly workshop.

Therefore, the cheapest machining centers launched by Taiwan-funded enterprises cost 600,000 yuan, which is not tens of thousands of yuan cheaper than the machine tools imported by domestic trading companies from their islands.

"Mr. Sun, what kind of accuracy has our machining center achieved now?" During this time, he was busy with the mobile phone company and Jiuyi materials, and Yun Fei paid little attention to the research progress of the processing center.

Therefore, after teaching the sales staff a lesson, they couldn't even take care of eating, so they brought Sun Lin and Situ Heyun, who were in charge of the research and improvement of the processing center, over.

"There hasn't been much progress, and now if you want to achieve higher machining accuracy, you have to find a way to do it. The maximum speed of the spindle can reach 8,000 revolutions per minute, but it can't last too long, otherwise the damage to the spindle will be very great......" Sun Lin said with a look of embarrassment.

The accuracy of a machining center is a comprehensive reflection of many things.

The precision of the servo motor imported from abroad is not high, but it is under the control of a powerful CNC system. It's barely possible to achieve a relatively high level of accuracy.

"What is the machining accuracy? What is the spindle repeatability? Yun Fei is too lazy to listen to Sun Lin's explanation now, and the accuracy is improving slowly.

He needs to know how long it will take to bring the CNC machine tools produced by Jiuyi Heavy Industry to the market.

"In terms of the theoretical machining accuracy of the JY850 in the limit size, the X-axis can reach 0.03mm, the Y-axis can reach 0.02mm, and the repeatability of the spindle can reach 0.02mm. If you can get a servo motor with better performance, this performance can be further improved. For the things that he studies every day, Sun Lin did not hesitate to report the data that he had read and listened to countless times every day.

In fact, a machining center with such precision has been able to be regarded as a mid-range machining center in front of you.

All data is required to be within 0.015 mm. Don't look at the fact that there are only five μ available, which is a very difficult parameter to raise.

At present, all the theoretical accuracy of high-end three-axis machining centers exported to China is in five μ, but the actual machining accuracy is generally about 0.02mm. The machining centers assembled in the experimental workshop, this comprehensive data is not much worse than the accuracy of the imported mid-range CNC machining centers, and even higher in some aspects.

"If we start mass production now, can we guarantee these processing accuracy? Especially in terms of the service life of our spindles? Yun Fei opened his mouth and asked Sun Lin.

In this regard, if we cannot stabilize ourselves, we can only watch those Taiwanese companies seize the market.

It's okay now. At least, the market in the entire southwest region is difficult for Taiwanese machine tool factories that have built factories in Chinese mainland to enter.

"These precisions are the ones that can be achieved during mass production, Xiaoyun, in fact, we should still produce while manufacturing. While conducting research. We conduct verification in the experimental workshop ourselves, which is not only costly, but also takes up a lot of money. If there is no Xin Kaixing, we have these data. In a matter of months, millions of dollars, it is impossible to verify at all. Sun Lin was depressed.

Finally, I came up with China's own CNC machine tools. Until now, none of them have been put on sale.

In addition to Rongcheng Xinkaixing Ball Screw Factory, there is almost no domestic three-axis machining center, even the worst precision of the low-grade machining center. How can this not make Sun Lin feel uncomfortable?

"Lao Wu, if we temporarily stop the processing of CNC milling machines now, and all those blanks are used to produce machining centers, can we produce fifty units a month?" Yun Fei didn't answer Sun Lin's words, but turned around and asked Wu Zhongda on the side.

Hearing Yun Fei's question, smiles immediately appeared on the faces of Sun Lin and Situ Heyun.

This kid finally figured it out and no longer insisted on researching what high-precision products were on the market.

"Boss, even if all the production capacity of CNC milling machines is put into the production of machining centers now, it can only produce a maximum of twenty-five units a month......" Wu Zhongda understood Yun Fei's thoughts.

This kid, this is being forced to be anxious.

Of course, I was depressed in my heart.

If Yunfei had upgraded the production scale of Jiuyi Heavy Industry at the beginning, there would have been no such problem at all.

The first workshops of Jiuding and Shenkun factories next to it have already started small-scale production, while the smelting workshop of Jiuyi Heavy Industry has to wait two months before large-scale production can begin.

In other words, it is necessary to wait until after August for the production capacity of Jiuyi Heavy Industry to expand on a large scale.

Of course, by then, the shortage of skilled assemblers will be a big problem.

Now there are more than 170 people in the assembly workshop of Jiuyi Heavy Industry, and the pressure of assembling 300 CNC lathes and 30 CNC milling machines every month is very large. If it were to be doubled, at least 150 assembly fitters would be needed.

"I invite you here today mainly to ask for your help. Now Jiuyi Heavy Industry has reached the moment of life and death...... "The next day, Yun Fei invited Zhao Xingbang and Huang Qiaosong to Jiuyi Heavy Industry.

The two of them were wondering what Yun Fei was doing when he invited him to Jiuyi Heavy Industry, after all, they didn't take advantage of Yun Fei's cooperation. Yun Fei directly went straight to the point and said the purpose.

"Xiaoyun, if there is anything, you can say it directly. You said so politely that I am very unaccustomed to it...... "Zhao Xingbang has dealt with Yun Fei for several years, except for the beginning when Yun Fei was not very familiar with Yun Fei, Yun Fei spoke very politely, and then there was never such a thing.

The relationship between Huang Qiaosong and Yun Fei is not very good, if it were not for the relationship between the old man and Ye Fei, he and Yun Fei would not have much intersection.

Even if Jiuyi Materials now has a lot of shares in their 132 factory, it is also operated by the people below, how much time does a big leader like him have to ask in person?

Now Yun Fei found himself here and asked for help, and he couldn't answer Yun Fei's words when he didn't know what kind of help Yun Fei wanted.

"Now that we're all partners, I'm not going to beat around the bush. During this time, several CNC machine tool factories in Taiwan have suddenly put a large number of low-end CNC machine tools on the market, which is very unfavorable to our Jiuyi Heavy Industry...... "Yun Fei first said about the situation of Taiwan's CNC machine tool factory.

"They are building factories on the mainland, haven't you heard any rumors?" Zhao Xingbang was speechless.

Yun Fei, this kid does things a lot of the time, almost always taking precautions, and rarely makes such a big mistake as now.

"Uh...... When I came back from North Korea, I have been busy with the affairs of the mobile phone factory and the material factory, and there is a lot of progress on your side of the Ninth Academy, so I don't pay too much attention to this matter......" Although I am embarrassed, but for Zhao Xingbang and Huang Qiaosong, Yun Fei did not hide the slightest reason why he did not get the news.

Of course, he was embarrassed to say that his men didn't take it seriously at all.

"And you're coming to us today?" Zhao Xingbang was speechless, the more embarrassed Yun Fei was to say the purpose, the more difficult it was to say the matter.

"Borrow!" Yun Fei categorically stated his purpose, "Borrow fitters, especially assembly fitters." In the entire land of Bashu, there are only two of you assembly fitters, of course, there are many assembly fitters in the aerospace, but all the outsourcing business has been taken back to Jiuding and Shenkun, and they are offended, so I won't look for this boring...... "If it weren't for offending aerospace, the person in charge of the aerospace industry would definitely appear here today."

"How much do you want to borrow?" The two said almost in unison.

Now whether it is the base of the Ninth Academy or the 132 factory, the production tasks have shrunk a lot, and many experienced assembly fitters have been seconded to those civilian workshops to do some product fitters such as deburring. Now if they are arranged to Jiuyi Heavy Industry to help with the assembly of CNC machine tools, at least, their skills will not be wasted.

Actually, that's a good thing.

At least, they will all benefit.

"Three hundred! If there are more, the more the merrier, it would be best if the family could lend me three hundred......" Yun Fei said embarrassedly.

The assembly of CNC machine tools has high requirements for fitters.

If there is a technical school, Yunfei can even directly transfer those students who have undergone one or two years of training to the workshop to do the most basic assembly work, and then let those experienced masters do it with precision, so that although the efficiency is low, the production capacity will definitely not be too low.

"......" The data that Yun Fei said made both of them almost breathless. (To be continued......)
