Seeing Tang Fei's denial, Zhang Ping seemed to have expected this, and he lowered his head and sighed.

When he came to Jiuzhou Industrial Group, he made various assumptions and made the worst plan, that is, Jiuzhou Industrial Group did not agree to reduce the processing accuracy requirements.

Actually, he knows this too. Reducing the machining accuracy will inevitably affect the overall performance of the drone engine, and may also affect the engine quality.

Seeing that Tang Fei denied this, Zhang Ping did not force it, did not think about convincing Tang Fei, but lowered his head and sighed softly. The domestic aero engine factory is facing such a problem, they do not have a high-precision advanced five-axis machining center, but they are afraid that it is difficult to overcome the technical problems of machining accuracy.

Tang Fei noticed Zhang Ping's expression, couldn't help but smile happily, picked up the tea and took a sip gently.

Seeing that Tang Fei actually laughed, Zhang Ping raised his head and looked at Tang Fei, his eyes were very puzzled, and he couldn't understand why Tang Fei was laughing so easily.

Tang Fei quickly gave the answer.

"Director Zhang, I don't agree to reduce the machining accuracy of engine parts, that's because our Jiuzhou Heavy Industry has such processing strength, and there are two advanced high-precision five-axis linkage CNC machining centers in the precision machining center of Jiuzhou Heavy Industry. ”

What the!

Zhang Ping's reaction was great, he stood up with a "brush", looked at Tang Fei with an unbelievable gaze, and said in surprise: "I... I heard it right, there is such advanced processing equipment in Jiuzhou Heavy Industry. ”

Tang Fei affirmed: "Yes, there are not only them, but there are two of them, the larger one can process workpieces with a maximum diameter of 1500 mm, and the smaller one can also process workpieces with a diameter of 800 mm." ”

"That's great!"

Receiving an affirmative answer from Tang Fei's mouth, Zhang Ping was overjoyed, clenched his fists hard, his tone was a few points higher, and blurted out the words "great".

In addition to being delighted, he also sat down and said happily: "Mr. Tang, this means that the machining accuracy problem we are facing is no longer a problem. ”

Tang Fei said: "Yes, this domestic aero engine company can put the finishing process of some parts in Jiuzhou Heavy Industry, and Jiuzhou Heavy Industry will help them complete this process." ”

That is, this enterprise can complete the preliminary processing of parts, including rough machining, semi-finishing machining. After the parts are semi-finished, they are sent to Jiuzhou Heavy Industry, which completes the high-precision machining of the parts.

That's totally okay.

Jiuzhou Heavy Industry has two high-precision CNC five-axis machining centers, and also has strong processing strength. From its establishment to the present, the time is not short, and it has accumulated a relatively solid processing foundation.

Next, Zhang Ping and Tang Fei talked about some specific matters of parts finishing.

After about an hour, the matter was settled and the problem was solved.

At noon, Tang Fei invited guests to dinner and had lunch at the hotel in the International Finance Building. After Tang Fei held his wedding here, the hotel officially opened for business, and it has been open for almost two months now, and business has been booming.

It should be stained with the light of the International Finance Building. This skyscraper is a landmark in Shenhai City and is currently among the top three high-rise buildings in China.

In such a building, there is a super five-star hotel, publicity and advertising are not necessary, it is also famous along with the International Finance Building, the entire Shenhai City, almost everyone knows that the 51st to 86th floors of the International Finance Building are the top office buildings. The 50th floor and below, dominated by this five-star hotel, are already huge shopping malls.

After lunch, Zhang Ping didn't even take a break at noon, just sat down to drink tea after the meal, and chatted with Tang Fei.

He wanted to see the two high-precision five-axis machining centers.

Tang Fei readily agreed, so everyone left the International Financial Building, went to Jiuzhou Heavy Industry, and arrived at Jiuzhou Heavy Factory at about two o'clock in the afternoon.

After receiving a notice that the boss and the military director Zhang Ping were coming over, Zhu Yifeng was already waiting there and greeting him, and when he saw Tang Fei and Zhang Ping getting out of the car, he walked over quickly.

"Hello boss, hello Director Zhang, welcome to Jiuzhou Heavy Industry. ”

Tang Fei nodded.

Zhang Ping was more surprised and said: "Mr. Zhu, the scale of your factory is not small, it is worthy of making heavy equipment, and the height of each plant is higher than that of ordinary factories." ”

This is the characteristic of the heavy equipment manufacturing plant, the plant is higher than the ordinary plant, because the heavy equipment is large, and the corresponding parts and components are relatively large.

For example, the diameter of a cutterhead is as small as 6 meters, and the diameter is as large as 9 meters, or even 12 meters, which requires a relatively high floor height workshop.

Zhu Yifeng smiled proudly, and also asked: "Boss, do you want to sit down first, or go to the manufacturing site now?"

Tang Fei said with a smile: "Our Director Zhang came to see the two high-precision five-axis machining centers, and we went directly to the precision machining center." ”

"Okay. ”

Zhu Yifeng accompanied Tang Fei and Zhang Ping, and behind the three of them was Xu Guangming and the guards brought by Zhang Ping. Everyone walked along the spacious and straight avenue in the factory area towards the precision machining center plant.

On the way, Zhang Ping almost gave a thumbs up again, he has been to the factory of Jiuzhou Industrial Group many times, and each factory is so clean and tidy, it is completely a garden-style factory.

The area of the factory is also relatively large, we walked for several minutes to walk to the precision machining plant, which is a large plant with an area of several thousand square meters, the construction standard is very high, there is a central air conditioning system, and it can achieve constant temperature and humidity all year round.

Basically stable temperature and humidity, which is the basic guarantee for high-precision processing, because the metal material will expand and contract, too cold in winter, too hot in summer, will affect the machining accuracy of parts.

Walking into this plant, Zhang Ping felt very comfortable, because the temperature in the plant was controlled at about 20 degrees, and the humidity was also in a very reasonable range, neither wet nor dry.

The plant is clean and neat, the ground is so clean that it can shine the human figure, and the parts and machine tools in the plant are placed neatly, reflecting a high level of on-site management.

Zhang Ping thought in his heart that the management level of Jiuzhou Industrial Group is high, which can be seen from this neat production site.

It didn't take long for everyone to walk next to these two precision five-axis machining centers, they are processing parts, next to each machine tool, there are some parts waiting to be processed, and some processed parts are also placed, and there are parts being processed on the machine tool.

That's the precision five-axis!

Zhang Ping recognized it at a glance, accelerated his pace invisibly, walked to one of the five-axis, and watched it process parts with great interest.

Whether it is a large shield machine, a large bridge erecting machine, or even a large mining truck that is currently in production and trial, their high-precision parts are processed in this building, and some of the complex precision parts are often processed on these two machines.

There are several mechanical processing plants of Jiuzhou Heavy Industry, and the area of each building is relatively large. The precision machining center plant is just one of them, which is mainly responsible for the machining of high-precision parts.

Zhang Ping stood next to one of the precision five-axis, looking at it seriously, he was a technical cadre of the military, not that he didn't understand anything, he looked at it for a while, and saw the doorway.

That's right, it's definitely a high-precision five-axis, and it looks very advanced.

After looking at the processing of the parts for a while, he looked at the processing drawings of the parts again, saw the high-precision dimensions on them, and nodded slightly.

With such machining accuracy, there should be no problem with the processing of high-precision parts for the drone engine, and those parts will definitely be processed smoothly.

Zhang Ping was very happy and held Tang Fei's hand tightly, "Mr. Tang, with these two high-precision CNC five-axis, I am completely relieved." ”

Tang Fei said confidently: "Director Zhang, don't worry, the finishing of some engine parts can be placed in Jiuzhou Zhongye Group." ”

"Good, good. Zhang Ping said two "good" words in a row.

After looking here for at least half an hour, Zhang Ping was full of interest and asked to visit the entire Jiuzhou Heavy Factory Area.

Tang Fei readily agreed and personally took him to visit Jiuzhou Heavy Industry. Not only went to several processing plants for visits. In these processing plants, Zhang Ping looked more carefully, and also knew that Jiuzhou heavy tools had strong processing strength.

He also went to the huge assembly center building, where he not only saw several large shield machines in the final assembly, but also several large bridge erecting machines that were being assembled.

In front of one of the large shield machines, Zhang Ping said: "Mr. Tang, this is a sharp weapon for digging holes, if our military has underground projects to be constructed, I think we can order a few from here." ”

Hearing this, Tang Fei was happy.

Unexpectedly, the military is also a potential customer, and one day, they may also order a large shield machine from Jiuzhou Heavy Industry for the construction of their underground projects.

It wasn't until more than five o'clock in the afternoon that Zhang Ping left the Jiuzhou Heavy Factory area unsatisfied, and after a day's time, his harvest was also huge.

The problems of single crystal superalloys and the machining accuracy of engine parts had to be solved, and he happily began to prepare to return to the capital.

Originally, he wanted to go to Dongguan City to see the construction of the drone factory, but all the problems were solved, he wanted to go back to the capital first, report to Minister Tang first, and then go to Dongguan City next time when he is free.

He didn't even eat dinner, he took the evening plane, left Shenhai City, returned to the capital, and brought back the good news to Minister Tang.

Far away in the capital, Tang Guoqiang is still waiting for news from Zhang Ping.

……

Today's three watches, the second one is sent!
