As the days go by, Tianfeng Technology Company has delivered several batches of parts to Factory E, and the processing quality of these parts is naturally very good, which is in stark contrast to the parts sent by other mechanical processing factories.

Such a good quality processing of parts, and continue like this for a period of time, Tianfeng Technology Company will definitely win a good reputation, perhaps, after a while, in the eyes of some people in E factory, Tianfeng Technology represents a synonym for high quality and high-quality products.

The No. 1 workshop is still busy, with rough parts being transported from factory E every day, and processed semi-finished parts being sent out from here to factory E every day.

Every day, Li Tianfeng has to go to the No. 1 workshop to take a look, and since the two things happened at the beginning, there has been no quality problem.

In your own office.

Li Tianfeng is answering a phone call, the phone is a machine tool equipment agency intermediary company called, this company is more famous in China, is also very powerful, Li Tianfeng is cooperating with this company, from Germany, Switzerland and other machine tool powers to buy high-quality machine tools.

At the beginning, the company did not take the new company Tianfeng Technology to heart, but when Li Tianfeng reported the list of equipment he was going to purchase, the purchase amount exceeded 100 million, involving precision machining centers, grinding and milling centers, deep hole machining centers, CNC cylindrical grinding, precision counting cars, etc., a package of bulk procurement plans, the processing company soon paid attention to it.

Just now, it was a vice president of the processing company who personally talked to Li Tianfeng on the phone, and the two of them roughly agreed on some matters on the phone, and the processing company will quickly send someone over to Tianfeng Technology Company for an interview, if nothing else, a purchase agreement will be signed.

Li Tianfeng attaches more importance to this matter, after the purchase of these equipment, for the No. 1 workshop, it is equivalent to a shotgun for a cannon, which will be completely upgraded to several grades.

The purchase of machine tools and equipment has been carried out in batches, the first batch of machine tools and equipment are mainly domestic equipment, such as Dalian Machine Tool Factory, Shenyang Machine Tool Factory's machine tool equipment, and there are fewer imported equipment from abroad, only a few German and Swiss equipment.

This batch of equipment has not only been procured in place, but also has been installed and commissioned, and has been officially put into use in the No. 1 workshop, and has processed many batches of parts, which are of excellent quality.

The second batch of equipment procurement, mainly domestic equipment and Taiwan machine tool equipment, of course, there are several machine tool agency intermediary companies from abroad to purchase some foreign equipment. This batch of equipment, in addition to the foreign equipment has a long cycle, the rest of the equipment will begin to arrive in Songzhou one after another, and will be installed and debugged in the near future.

The third batch of equipment is a package of machine tools and equipment purchased from abroad by Li Tianfeng entrusted by Li Tianfeng to this very powerful machine tool and equipment agency intermediary company, worth more than 100 million yuan in bulk purchases, these machine tools and equipment are absolutely first-class in China, and even some of them will be top-notch.

Of course, the purchase of machine tools and equipment is definitely more than these three batches, with the completion of a plant, put into use, there will be a welding center, a casting engineering center, a heat treatment center, a material research center, etc., in addition to continuing to purchase machine tools and equipment, will also purchase advanced welding equipment, heat treatment equipment, and even special material smelting equipment and so on.

Tianfeng Technology Co., Ltd., in order to grow into an enterprise that can develop and manufacture advanced aero engines, the amount of equipment procurement is at least more than a billion, or even billions.

Of course, only advanced equipment, advanced workshops, and good factory hardware strength are not enough, but more importantly, soft power, such as the construction of talent team, the establishment of technical team, the establishment of management team, etc.

After hanging up the phone, thinking that the machine tool and equipment agency intermediary company would send someone over in two days, Li Tianfeng was ready to go to the engineering technology center to see how the equipment and technical agreements of Zeng Qinghai and others were prepared.

Tianfeng Technology Co., Ltd. Engineering Technology Center, Zeng Qinghai is the minister, Wu Shungao is the vice minister, the technical level of the two is good, otherwise, Li Tianfeng will not be entrusted with important tasks, one as a minister, the other as a vice minister.

Wu Shungao was dug by Li Tianfeng from the corner of the E factory, and at present, Tianfeng Technology Company is short of people, so it can only quietly dig the corner from the E factory first.

With Wu Shungao, there were several technicians, a senior engineer, two engineers, in addition, Zeng Qinghai also brought a few technicians from his original work unit, these people are of good level, Li Tianfeng is more satisfied.

Now, the engineering and technical personnel of the engineering technology center finally have nearly 20 people, the initial operation, is gradually playing a role, the purchase of foreign machine tools, each kind of machine tool equipment technical agreement, are the technical personnel of the engineering technology center responsible for the preparation.

Seeing Li Tianfeng coming, Zeng Qinghai immediately said enthusiastically: "Mr. Li, you came here in person!" ”

In Zeng Qinghai's office, Li Tianfeng sat down, and then said: "Minister Zeng, how is the technical agreement for the procurement of that batch of machine tools and equipment prepared?" ”

The compilation of technical agreements is an important task, and Zeng Qinghai has always regarded this as a key task, and the compilation and proofreading work has been basically completed.

Zeng Qinghai said: "Mr. Li, the work is basically completed, I will take all these agreements, how about you take a look?" ”

Li Tianfeng came in person, naturally to take a look at these machine tool technical agreements, these machine tools, all from Germany, or Switzerland and other countries to buy, the technical agreement must be prepared reasonably, can not let foreigners take advantage of the loopholes.

Because there are more machine tools and equipment to be purchased, the technical agreement is a thick stack, half a foot high, and Zeng Qinghai personally moved over.

Li Tianfeng found a few more important ones, and looked at them carefully, these technical agreements, a machine tool compilation, neatly bound, looked more comfortable.

The large-scale precision six-axis linkage digital milling center, which is ready to be purchased from a well-known Swiss machine tool manufacturer, worth more than 15 million, can process large fan integral blade discs with a diameter of one meter, and also CNC milling large blades.

Holding the technical agreement of this machine tool, Li Tianfeng looked at it very carefully and very carefully, and even saw that there was a punctuation error in it.

"Minister Zeng, the agreement is good as a whole, the basic number of machine tools, the accuracy of machine tools, etc. are also more appropriate, but it should be noted that it is an EU standard, not our domestic standard."

There is a big difference between these two standards, such as the same repeated positioning accuracy of three thousandths, how to adopt the EU standard, the repeated positioning accuracy of the machine tool is obviously better than the domestic standard, that is to say, the use of the EU standard, the overall quality of the machine tool, the overall accuracy is a grade better.

Zeng Qinghai also immediately realized this problem, and immediately said: "Mr. Li, then we will all adopt EU standards." ”

"Hmm." Li Tianfeng nodded, and reminded in particular: "In the future, all machine tools and equipment purchased from abroad will adopt EU standards or American standards, and only domestic equipment purchased in China will adopt national standards." ”

Li Tianfeng's words, Zeng Qinghai naturally remembered in his heart, thought about it, Zeng Qinghai said: "Mr. Li, we will purchase this large-scale precision six-axis linkage digital milling center from Switzerland, in the technical agreement, whether to improve the accuracy level by one level, so that the accuracy of the equipment will be higher." ”

Li Tianfeng naturally knew what Zeng Qinghai meant, and Li Tianfeng also wanted to buy machine tools with better quality and higher precision, but he must be able to buy it with money alone.

Li Tianfeng sighed lightly and said: "Qinghai, our large-scale precision six-axis linkage digital milling center has already touched the line, and if we improve the accuracy level, the machine tool factory in Switzerland will not sell it to us, and even if it can be sold to us, it will cause a lot of trouble." ”

"Yes, yes, technical blockade." Zeng Qinghai also immediately understood.

After reading the technical agreement of this large-scale precision six-axis linkage digital milling center, Li Tianfeng picked up the technical agreement of a large-scale high-precision CNC cylindrical grinder, which is also what Li Tianfeng needs.

Because, there are some parts of the aero engine outer circle, there are high size and technical requirements, such as some shaft parts, the journal part of the bearing is installed, the size tolerance is often within a trace, only a few thousandths of a tolerance, and the circular axial degree is only about two or three thousandths.

A trace is one hundredth of a millimeter, two thousandths and three is two or three microns, such strict requirements, the general ordinary cylindrical grinder is difficult to achieve, must have a high-precision CNC cylindrical grinder.

Tianfeng Technology Co., Ltd. will develop and produce advanced aero engines by itself in the future, and such equipment must be available, and the accuracy should not be too bad.

This large-scale high-precision CNC cylindrical grinder, in the EU's technical blockade agreement, is also the basic contact line, no matter how high the precision, it is a high-precision machine tool that is prohibited from exporting to China.

In addition to such a large-scale high-precision CNC cylindrical grinding machine, there is also an advanced deep hole drilling machine, a high-precision large-scale CNC broaching machine, etc. are the key equipment of this procurement.

In addition to these key equipment, there are some general equipment, although it is said to be general equipment, but in China, it is absolutely first-class, belonging to the top equipment, such as some good quality, high precision German CNC lathes, three-coordinate CNC drilling and milling machine, in addition, there are some precision measuring equipment, such as high-precision cylindrical instrument, high-precision large-scale three-coordinate measuring instrument and so on.
