I had a whole morning meeting with those overseas sales personnel in the factory, but I didn''t get any effective suggestions. Even I didn''t know the production scale of those factories. Only know that those who lost their soul to the Chinese market not only have a large number of CNC milling machines, but also many CNC machining centers with low machining accuracy.
The most important thing for the cloud is that these Taiwanese enterprises are now starting to attack the CNC Lathe Market in Chinese mainland.
Shouldn''t they focus on China''s three-axis and four-axis machining center market?
Fortunately, these salespeople had inquired about the price of the equipment of Taiwan funded enterprises before they came back.
Perhaps they think that their products are more technical than Chinese manufacturers, and the machining accuracy is even a little worse than that of the CNC lathe of 91 heavy industry. The price is 10000 or 20000 more expensive than that of 91 heavy industry.
At present, there are only less than 30 CNC milling machines introduced to the market every month, and the machining center is still waiting for the final assembly after the completion of the test in the assembly workshop.
Therefore, the cheapest processing centers launched by Taiwan funded enterprises cost 600000 yuan, which is not tens of thousands of yuan cheaper than the machine tools imported from their island by domestic trading companies.
"Mr. Sun, what precision has our machining center reached now?" During this time, I was busy with the mobile phone company and the materials of September 1. I paid little attention to the research progress of the processing center.
Therefore, after teaching the salesperson a lesson, he couldn''t even eat, so he found Sun Lin and situ Heyun, who were responsible for the research and improvement of the processing center.
"There is still not much progress. Now if you want to achieve higher machining accuracy, you can only think of ways in assembly. The maximum speed of the spindle can reach 8000 rpm, but it can''t last too long, otherwise it will cause great damage to the spindle... "Sun Lin said with an embarrassed face.
The accuracy of machining center is a comprehensive reflection of many things.
The precision of servo motor imported from abroad is not high, but under the control of powerful CNC system, it can barely achieve relatively high precision.
"What is the machining accuracy? What is the spindle repeat positioning accuracy? " Yun Fei is too lazy to listen to Sun Lin explain why the accuracy is improved 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 limit dimension of jy850, the x-axis can reach 0.03mm, the y-axis can reach 0.02mm, and the repeated positioning accuracy of the spindle can reach 0.02mm. If we can get a servo motor with better performance, this performance can be further improved. " For the things studied every day, Sun Lin reported the data he had seen and listened to countless times every day without hesitation.
In fact, such a precision machining center can be regarded as a middle-grade machining center.
The cloud does not require all data to be within 0.015mm, although there are only five μ This is a very difficult parameter to improve.
At present, all the theoretical accuracy of high-grade three-axis machining centers exported to China is within five μ， However, the actual machining accuracy is generally about 0.02mm. The comprehensive data of the machining centers assembled in the experimental workshop is not much worse than that of the imported medium-sized CNC machining centers, and even higher in some aspects.
"If we start mass production now, can these machining accuracy be guaranteed? Especially the service life of our spindle? " Yun Fei asks sun Lin.
On the one hand, if we can not stabilize, we can only watch those Taiwan enterprises seize the market.
Well, at least, the market of the whole southwest area is difficult to get into the Taiwan machine tool factory built in Chinese mainland.
"These accuracies are the accuracies that can be achieved in mass production. Xiaoyun, in fact, we should conduct research while manufacturing. Our own verification in the experimental workshop is not only costly, but also takes up a lot of funds. Without xinkaixing, we can''t verify these data without several months and millions of funds. " Sun Lin is very depressed.
It was not easy to get out China''s own CNC machine tools, but up to now, none of them have been sold on the market.
In addition to Chengdu xinkaixing ball screw factory, almost no domestic three-axis machining center can be seen in China, even the low-grade machining center with the worst accuracy. How can this not make Sun Lin uncomfortable?
"Lao Wu, if we temporarily stop the processing of CNC milling machines now and all the blanks are used to produce machining centers, can we produce 50 units a month?" Yunfei didn''t answer Sun Lin''s words, but turned to ask Wu Zhongda.
Hearing Yunfei''s question, Sun Lin and situ Heyun immediately showed a smile on their faces.
The boy finally figured it out and no longer insisted on developing products with high precision and going on the market.
"Boss, even if we put the production capacity of all CNC milling machines into the production of the machining center, we can only produce 25 sets at most a month..." Wu Zhongda understood Yun Fei''s mind.
This boy, this is forced.
Of course, my heart is depressed.
If Yunfei upgraded the production scale of Jiuyi heavy industry at the beginning, such a problem would not occur at all now.
The first workshop built by Jiuding and Shenkun factories nearby has started small-scale production, while the smelting workshop of Jiuyi heavy industry has to wait two months to start large-scale production.
In other words, it is necessary to wait until August before the production capacity of 91 heavy industry can be expanded on a large scale.
Of course, at that time, the gap of skilled assemblers is not a small problem.
Now there are more than 170 people in the assembly workshop of 91 heavy industry. There is a great pressure to assemble 300 CNC lathes and 30 CNC milling machines every month. If it were to be doubled, at least 150 fitters would be needed.
"I''d like to invite you to come today, mainly to ask you for 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.
They are wondering why Yunfei asked him to come to 91 heavy industry. After all, they didn''t take advantage of their cooperation with Yunfei. Yun said his purpose directly.
"Xiao Yun, just tell me what''s going on. I''m not used to your politeness... "Zhao Xingbang has been dealing with Yun Fei for several years. Except when he was not very familiar with Yun Fei at the beginning, Yun Fei spoke politely. Later, there has never been such a thing.
Huang qiaosong''s relationship with Yunfei is not very good. Without the relationship between the old man and ye xuanmei, he won''t have much intersection with Yunfei.
Even now, 91 materials has a lot of shares in their 132 factory, which is also operated by the following people. How much time does a big leader like him have to personally intervene?
Now Yunfei finds himself here and asks for help. When he doesn''t know what kind of help Yunfei wants, he can''t answer Yunfei''s words.
"Now that we are all partners, I won''t beat around the bush. During this time, several CNC machine tool factories in Taiwan have suddenly put a large number of medium and low-end CNC machine tools on the market, which is very unfavorable to our 91 heavy industry... "Yun Fei first explained the situation of CNC machine tool factories in Taiwan.
"They built factories in the mainland. Haven''t you heard any news?" Zhao Xingbang was speechless.
Yun Fei always works in advance. He rarely makes such a big mistake.
"Er... When I came back from North Korea, I was busy with the mobile phone factory and material factory. In addition, your ninth hospital delayed a lot of progress, so I didn''t pay much attention to this..." although I''m sorry, Yun Fei didn''t hide the reason why he didn''t get the news for Zhao Xingbang and Huang qiaosong.
Of course, he was embarrassed to say that his people didn''t take it seriously at all.
"So you came to us today?" Zhao Xingbang is speechless. The more embarrassed Yun Fei is to say the purpose, the more difficult it is to say things.
"Borrower!" Yun Fei said his purpose firmly, "borrow fitters, especially assembly fitters. You two are the only two assembly fitters in Bashu. Of course, there are many assembly fitters in aerospace, but I took back all the outsourcing business to Jiuding and Shenkun. If they offended them hard, I wouldn''t look for this. It''s boring... "If I didn''t offend aerospace, The person in charge of today''s Aerospace will certainly be here.
"How much do you want to borrow?" They said almost in unison.
Now, whether it is the base of No. 9 institute or factory 132, the production tasks have shrunk a lot. Many experienced assembly fitters have been seconded to those civilian product workshops to do some product fitters such as deburring. Now, if they are assigned to Jiuyi heavy industry to help with the assembly of CNC machine tools, at least their skills will not be abandoned.
In fact, this is a good thing.
At least, it will benefit.
"Three hundred! If there are more, the more the better. It''s best if one family can lend me 300... "Yun Fei said shyly.
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 been trained for one or two years to the workshop to do the most basic assembly work, and then let those experienced teachers do it with precision. Although the efficiency is low, the production capacity will not be too low.
"...." the data that Yun Fei said almost made both of them breathless.
