Chengnan base, a workshop for large parts.

In the workshop, a large CNC gantry milling machine purchased from Germany is being installed, in addition to several equipment personnel from Tianfeng Technology Company, there are also two German technicians.

The German side did not send engineering and technical personnel to come over for installation, at the beginning, the equipment personnel of Tianfeng Technology Company were quite complaining, but soon there was no opinion, the performance of these two German technicians was very good.

With everyone's cooperation, the equipment installation is very in place, the installation of several major components has been completed, and some accessories of the machine tool are being installed.

"Lao Huang, the travel of this equipment is really big, look at this guide rail, at least fifty meters."

Lao Huang is an equipment worker, Lao Huang said proudly: "The length of the guide rail is 60 meters, and it can process any parts below 60 meters." ”

"My goodness, sixty meters of parts!"

While installing, we chatted about the day, and from time to time, some people exclaimed slightly, such a large equipment, a total of two in the first workshop of large parts.

In addition to these two big guys, there are two CNC gantry milling machines with a stroke of 35 meters in the second workshop of large parts, such equipment, can count milling, can also drill, can be described as a combination of drilling and milling, processing accuracy is also very high, in order to enter the aircraft manufacturing industry, in terms of equipment, Tianfeng Technology Company can be regarded as a full cost.

The installation and commissioning of equipment has begun in the south of the city base for two or three months, and now, many plants have been installed and have begun to enter the production stage.

Of course, it is Bombardier parts that are manufactured, such as the first workshop, where two or three hundred skilled workers are in full swing.

Walking into the workshop, you can find that it is well-planned, very neat and brand-new equipment. The ground is so bright that you can almost see the shadow of a person, and you can see the parts being processed at each station.

In addition to wings, tails, rudders, hatches and other parts, there are more structural parts on the aircraft.

Structural parts are one of the most important types of aircraft parts. This type of parts is mainly made of aluminum alloy. Based on manufacturing process and part weight considerations. In the past, it was mainly made of riveted aluminum plates.

Now, the structural parts of the passenger aircraft processed by Tianfeng Technology for Bombardier are not made of aluminum alloy, but are produced and manufactured using Hercules materials.

The material is no longer aluminum alloy, the manufacturing process, and the design of these structural parts are no longer the same, and after full technical communication between Tianfeng Technology and Bombardier, these airliner parts have adopted a new design.

This new design takes a completely different approach. The integration of many different functions into a single structural part is known as integrated design technology.

Generally speaking, the structural parts of passenger aircraft are milled from a solid aluminum billet. This type of part is very complex, usually containing a very small bottom surface and thin walls (0.6~2mm), which is honeycomb-shaped. The geometry of these parts consists of different surfaces and defined surfaces.

The disadvantage of this design and processing technology is that the material utilization rate is very low, and the processing is very complex, time-consuming and labor-intensive.

After adopting new design technology and processing technology. The parts are processed quickly and the cost is greatly reduced. The first batch of structural parts, only more than 20 days of processing cycle, has been processed at this time, and entered the inspection process.

A workshop for the processing of structural parts.

Li Tianfeng and Bombardier Vice President Smith are in the finished product area of the workshop, where the first batch of processed structural parts of a passenger aircraft have been placed.

Smith looked at the parts seriously, and the joy and excitement on his face were very obvious. While watching it, he shouted excitedly, without the image of a vice president.

"Oh God, I can't believe it, Mr. Li. The part is so beautifully machined and the weight of the part is so light. ”

Li Tianfeng smiled, Li Tianfeng was also satisfied with the processing quality of this batch of parts, not only the appearance and size of the parts were processed very well, but the performance of the parts was even better.

Li Tianfeng also knows that the performance of these structural parts will be very good when using Hercules materials and no longer aluminum alloy materials, but Li Tianfeng is still very happy to see the data on the performance report.

Li Tianfeng said: "Mr. Smith, you can take a look at the static experiment report again." ”

Smith, who was happy and excited in his heart, held the static test report of the parts, and it seemed that this was an all-English experiment report, and the data on it were very clear and detailed.

After looking at it for a while, Smith said: "Mr. Li, the static performance of this part is much stronger than that of similar parts made of aluminum alloy!" I can't believe it. ”

Li Tianfeng said: "Mr. Smith, congratulations, the performance of this batch of parts is very good, and the weight is about 30% lighter than the same aluminum alloy parts. ”

Smith said happily: "Mr. Li, thank you." ”

Li Tianfeng smiled and nodded, with an expression of "you have made a lot of money", these Hercules material parts, with integrated design, the price is only less than two percent higher than the price of the same type of aluminum alloy material.

In fact, the big profit is Tianfeng Technology Company, Hercules material parts, its processing cost is slightly lower than similar aluminum alloy parts, and it is sold almost 20% more expensive than aluminum alloy structural parts, and the profit is very considerable.

However, this is a trade secret, and no one in other companies will know about the high profits in it.

For the delivery of the first batch of structural parts, Smith personally came to Tianfeng Technology Company and personally accepted the batch of structural parts to be delivered, and Smith was very satisfied and full of praise.

Even, Smith happily shook Li Tianfeng's hand and said, "Mr. Li, cooperating with you is the wisest choice we have made." ”

The first parts were delivered, and a simple delivery ceremony was also held between the two parties, and when the ceremony was completed, the parts began to be packed, boxed, and then shipped to Bombardier.

As for transportation, there is no need to worry about Tianfeng Technology, the two parties agreed that the parts will be delivered at Tianfeng Technology, and after delivery, Bombardier will be responsible for transporting them.

Based on such an agreement, the Chengnan base, close to the logistics back door, is close to a large factory, which is more than 10,000 square meters, which is the parts delivery workshop of the Chengnan base.

Later, the parts that need to be delivered are transported to this workshop, and then the parts are accepted, packed, packed and shipped here.

Bombardier's acceptance representatives can enter this workshop, as for the other workshops, sorry, they can't just come in and out.

Mr. Smith returned to Canada happily, and soon after, a large number of drawings of various passenger aircraft parts that Bombardier needed to process were sent to Tianfeng Technology.

After the official start of production, the first manufacturing workshop at the Chengnan base is Bombardier's various parts.

………

After Smith happily returned, within a few days, Tianfeng Technology Company welcomed Marceldo, vice president of Embraer, and his party.

The two sides are old relations, and the cooperation is not a year or two, Liu Wei took a car to Huangping Airport and picked up Marcel and his entourage to the State Guest Hotel, and there was no even need for Xu Lilong to pick up the plane in person.

On the second day of arriving in Songzhou, Marcel and his entourage arrived at Tianfeng Technology Company early in the morning, and in the reception room, Li Tianfeng, Xu Lilong and others personally received Marcel and his party.

When the two sides started, they were greeting each other, but they didn't get into the topic, Xu Lilong said: "Mr. Marceldo, I remember that you haven't come to our Tianfeng Technology Company for at least two years." ”

Marcel said: "It's been two years and three months, and in more than two years, the development and changes of Tianfeng Technology Company are very amazing. ”

Tianfeng Technology Co., Ltd. and Embraer, the two sides have been in a cooperative relationship for many years, and the order of engines from both sides basically no longer requires Marceldo, the vice president, to come to Tianfeng Technology in person.

The share of Tianfeng Technology's engines in Embraer's engine procurement has also risen from one or two percent at the beginning of the cooperation between the two sides to about forty percent now.

Tianfeng Technology Co., Ltd. occupies a 40% share, which is already a very good result, and the remaining 60% share is divided by several other aero-engine companies, including GM, Pratt & Whitney and other well-known large companies.

Competing with such a number of well-known engine companies, it is already a very good achievement to occupy a forty percent share.

However, today Li Tianfeng has a hunch that from today onwards, this data will be broken, and it may no longer be forty percent, but will be higher.

After a pleasantry, Marcel said: "Mr. Li, your engine is very good and excellent, especially the cost performance is very suitable, and what is even more commendable is that none of these engines have any failures so far, which is very rare." ”

After speaking, Marcel said: "Mr. Li, after the research and decision of our board of directors, we are ready to order your engine again." ”

Li Tianfeng smiled, "Mr. Marceldo, we have been in a cooperative relationship for many years, and the price of the engine remains the same. ”

Everyone in Tianfeng Technology Company, including Xu Lilong, thought in their hearts that Marcel is not just a business visit, it is only now that it has started, and it is about to order engines, and it seems that the number of engines ordered is still quite a lot.

Marcel said: "Mr. Li, you are really a friend, we decided to order 100 turbofan 17 engines, 100 turbofan 18 engines, and 200 turbofan 21 engines." ”

A total of 400 engines, with a total value of nearly 12 billion yuan, can be regarded as a big order.

Li Tianfeng said happily: "Mr. Marceldo, thank you for ordering our engine again. ”

Soon, a formal contract was signed, and the deal was negotiated.

However, Li Tianfeng has a hunch that Marceldo must not have come to order engines so simply.
