For Duan Yun, the successful installation of these two CNC machine tools made his own machining factory truly established.

As for the rest of the other things, having Dajun and Li Guosheng is enough to do it, and he doesn't need to worry too much.

In the final analysis, whether it is an electronics factory or a machining factory, Duan Yun is best at core technology and business contacts, as for other chores such as the preparation and management of the factory, Duan Yun is handed over to his subordinates to do, after all, so many people can't be raised in vain.

After installing the machine, Duan Yun did not return to Guangzhou immediately, but rested with the workers who installed it in the morning, and then continued to debug and test the machine in the afternoon.

After the installation of the program-controlled machine tool, the operation is a big problem, Duan Yun itself will be proficient in the use of this kind of machine, but for the current Chinese, there are many technicians who can operate ordinary machine tools, but there are very few operators who can use CNC machine tools, and they are basically concentrated in the national high-end military industry, and it is difficult for private enterprises to find an operator of CNC machine tools.

Duan Yun's two factories in Shenzhen want to be officially opened in early November, there are still more than 20 days to go, Duan Yun's idea is to let Li Guosheng and Dajun recruit CNC machine tool operators in Guangzhou and Shenzhen with high salaries, if you can't recruit people, then Duan Yun can only wait for the Canton Fair, personally train a few CNC operators.

In a whole afternoon, Duan Yun operated these two machining programs to make the first batch of sample workpieces, which were made according to the drawings of the core components of Duan Yun Longteng gearbox, which was very efficient and very accurate.

In Duan Yun's view, these two five-axis machining centers imported from Taiwan can process gear parts with a maximum accuracy of 4 from the perspective of product processing accuracy, compared with the CNC machine tool he modified in the Red Star Labor Service Company, the accuracy is a level higher, and the processing of such accuracy does not require reprocessing of grinding machines and other equipment, which makes Duan Yun feel very satisfied.

Generally speaking, the gear accuracy of agricultural tractors and truck automobile gearboxes is at level 6~9, and that of light vehicles is level 5~8, while the accuracy of level 4 can already reach the accuracy of aero engines.

The machining accuracy of grade 4 is relatively high in the current world, although it does not reach the international top level, but it is no problem to produce auto parts that can reach the international level with these two machines.

In fact, Taiwan's key parts of these machine tools are imported from Japan, in addition to some of the top machine tools banned by the Japanese government, other high-end machine tool parts, Taiwan can be purchased from Japan.

In Duan Yun's view, these two Taiwanese machine tools and their previous life in the locomotive factory during the use of the domestic CNC machine tools performance is similar, but here to explain that these domestic machine tools are after 2000, only to gradually achieve domestic, from this aspect, the domestic machine tool industry and Europe, the United States, Japan and other developed countries, the gap is full twenty or thirty years.

But in any case, seeing the good performance of these two machines, this also made Duan Yun breathe a sigh of relief, before he paid more than 2 million yuan to buy the machine tool, now it seems to be worth the money, at least for a long time, the machining accuracy of his two machine tools in China is very high, in addition to the kind of high-precision CNC machine tools used by the national military industry, the general private enterprises and even state-owned large machine tool factories, their machine tool products are difficult to hit the processing progress of Duan Yun's several factories, which also allows Duan Yun to maintain a leading position in technology for at least a few years or even more than ten years in China。

After operating these machines to make a batch of sample workpieces, Duan Yun arranged for people to transport these workpieces to the Guangzhou office, and after some maintenance of the two machines, they were temporarily sealed, and also specially instructed the army to arrange a few more security personnel to focus on guarding the two machines to prevent anyone from destroying or stealing.

After dealing with this matter, Duan Yun and Li Guosheng returned to Guangzhou by car on the morning of the second day.

Just when Duan Yun was busy debugging the CNC machining center, Cheng Qingyan was also seriously participating in the training of the Canton Fair, bringing a good pen and notebook every day, studying during the day, and communicating with representatives of other manufacturers at night, and the day arrangement was very fulfilling.

As a top student, Cheng Qingyan is very serious in everything she does, and this participation in the Canton Fair has undoubtedly opened a window in her life and given her the opportunity to see a broader world.

In addition to study and training, on the second night of coming to Guangzhou, Cheng Qingyan was pulled out by her best friends Yu Shulan and Zhang Xiulan to go shopping together.

Yu Shulan and Zhang Xiulan This is the third time to participate in the Canton Fair, and they are already very familiar with the environment in the urban area of Guangzhou, in their opinion, the most important preparation for participating in the Canton Fair is to buy clothes, shoes and accessories, and the two of them also know their positioning in the Canton Fair, in fact, it is to attract foreign guests to Duan Yun's booth as a vase.

But in any case, Duan Yun's trick is still very effective, in the context of all the manufacturers in the entire exhibition hall wearing more serious clothes, Duan Yun in suits and leather shoes and Yu Shulan and Zhang Xiulan can indeed attract the attention of a large number of foreign businessmen.

In fact, Duan Yun also explained to Cheng Qingyan before that after she went to Guangzhou, she would take the time to buy a few more beautiful clothes, and also left her 1,000 yuan in cash, so that Cheng Qingyan could buy as many high-end clothes as possible.

Although he is thousands of miles away from home, he is accompanied by her husband, girlfriends and friends, and Cheng Qingyan does not feel uncomfortable, but the bustling night scene of Guangzhou makes him feel very novel.

"Qingyan, you try this dress, this is the latest style that is popular in Gangtai this year, a round-neck polyester dress, plus a small suit jacket, I saw a model wearing it like this in a magazine, your figure is so good, and your temperament matches ......" In the clothing hall of Guangzhou Department Store, Zhang Xiulan picked up a dress and said to Cheng Qingyan.

Today's Zhang Xiulan has become the "fashionista" of Tianyin Electronics Factory, she has a good appearance and a good figure, although she is not as good as Cheng Qingyan, but she is also a beauty in a hundred, because she has been engaged in reception and public relations work in the factory, so she has very high requirements for grooming, for which he has subscribed to some domestic fashion magazines, and Duan Yun will also give her some extra clothing fees every month, so in the selection of clothes, Zhang Xiulan is definitely counted.
