Countercurrent 1982

Chapter 873 Propeller Model

"The two brand-new digital machining centers that our Longteng Machinery Factory bought at a high price are at the leading level in China. They can process parts with an accuracy of around 4, and they are very efficient. They are completely compatible with other equipment in the factory. It is capable of producing international mainstream gearbox parts and components." Duan Yun said to Qiu Jianlin.

At this point, Duan Yun must demonstrate convincing strength in front of Qiu Jianlin, and only in this way can his enterprise attract the attention of the SZ city government.

If it is placed in later generations or even 10 years later, the two machining centers of Duan Yun are not worth mentioning. At that time, there will definitely be a large number of manufacturers with advanced equipment stationed in Shenzhen. There are many companies doing business, but very few companies engaged in industry. Most of them use very outdated equipment, including some Hong Kong-funded enterprises, which also use obsolete old equipment in the Shenzhen factory. As far as Longteng Machinery Factory has two CNC machining centers, it is already very powerful.

"You said that these two machine tools of yours are new?" Qiu Jianlin asked suspiciously, looking at the machining center's shell that had no manufacturer's logo and seemed to have just been painted.

"Mayor Qiu..." Duan Yun posted to Qiu Jianlin at this time, and whispered to him: "Let me tell you the truth, I bought these two machines at a high price through an import and export foreign trade company in Xiamen. This equipment is very difficult, because machine tools of this specification are prohibited from being sold to the mainland in Taiwan, so when the machine casing was shipped in, the trademarks and nameplates on it were scratched off..."

Duan Yun is not worried about what will happen to Qiu Jianlin if he tells the truth, because Xiamen Yuanfang Company is a formally registered company, and Duan Yun has all the legal purchase procedures, so although it is smuggled, from the perspective of Duan Yun's buyer In other words, he did not break the law.

"So that's how it is." Hearing this, Qiu Jianlin was stunned.

Qiu Jianlin also knows a lot about the situation in Xiamen. In the past few years, a large number of household appliances, televisions, and refrigerators have entered the country through special channels. In addition, in recent years, some companies in Xiamen have also imported a large number of computers into the mainland. This is an open secret. After all, a lot of equipment is needed by the country. Since it is good for the country, the relevant government departments will naturally turn a blind eye. This is not a big deal.

After Duan Yun's explanation, Qiu Jianlin became very interested in Duan Yun's two machining centers.

"I'll show you the working performance of this machine." Duan Yun turned his head and glanced at Erhu, and said to him, "Go get a No. 3 material and put him in."

"Okay." After Erhu responded, he brought a piece of aluminum alloy raw material from the material preparation table next to him, wiped it briefly, opened the outer door of the machining center, and put it into the pad iron in the workbench. After the workpiece is clamped, it retreats to the side.

Afterwards, Duan Yun changed the tools inside, closed the protective door, and came to the CNC table.

Duan Yun wants to make a model of a small marine propeller. Generally speaking, the NC program for making a propeller is more complicated, but the program was compiled in advance when Duan Yun tested the machine a few days ago, so he only needs to call out the stored program this time. , After changing the tool, press the start button to start the formal processing.

"Buzz!" The moment the machine started, there was a slight buzzing sound, and the internal cutter head slowly approached the workpiece.

At this moment, everyone's eyes were focused on this CNC machine tool. For the entrepreneurs present, the leading cadres in the city and the district, it was basically the first time they had the opportunity to watch this CNC machine tool. Some people even heard of CNC machine tools for the first time, so many people present showed surprise and excitement on their faces.

"Squeak!" With the rapid rotation of the cutter head, the first piece of metal chips fell off the workpiece, making a slight and sharp sound.

At this moment, even the old technicians in the factory gathered around one after another. Some of them have been operating machine tools for half their lives, but this is the first time they have seen the processing method of speed-controlled machine tools with their own eyes. The equipment is very tightly protected, guarded by security personnel 1 hours a day, and even the workers in the factory cannot easily approach, so it is the first time for these factory masters to see how CNC machine tools work.

Through the glass protective cover, you can clearly see that the cutter head inside is working quickly and efficiently, and every movement is very smooth and precise, with an indescribable beauty.

The raw material Duan Yun used this time is relatively soft aluminum alloy, which is not easy to damage the cutter head during processing, and is very efficient, which is very suitable for product demonstrations.

At this time, Qiu Jianlin, who was standing next to Duan Yun, stared at the workpiece inside the machine tool intently. The five-axis linkage working mode made him feel very novel. For Qiu Jianlin, who was used to operating ordinary lathes in the past, this five-axis linkage CNC The working method of the machining center is full of sense of technology, and he was completely attracted at this moment.

"It is impossible to process such a propeller workpiece with an ordinary lathe, but with this five-axis linkage digital machining center, it is possible to easily make such a workpiece with a complex curved surface. At present, there are only a few in our country. Several large shipyards and military industry departments have this kind of CNC machining center. With these two machines, our factory can not only produce ordinary products, but also produce some high-end complex precision parts. The advantages of our factory's technical equipment are also in China It is considered to be in the lead." Duan Yun explained to Qiu Jianlin from the side.

"Not bad..." Qiu Jianlin nodded when he heard the words, and continued: "This is indeed a high-tech equipment. Shenzhen Special Economic Zone needs companies like yours."

"Actually, the reason why I chose to come to Shenzhen to set up this machinery factory was mainly because I wanted to export..."

"As far as I know, you are still the general manager of Shanxi Red Star Labor Service Company?" Qiu Jianlin asked suddenly.

"Yes, I am still the general manager of Red Star Labor Service Company, but in a few days I will return to Shanxi to resign as a manager and focus on running this machinery factory well..." Duan Yun paused, then continued : "In addition, I also greeted the leaders of our provincial department in Shanxi. After I left, I opened this Longteng Machinery Factory. I will still maintain business contacts with the Red Star Labor Service Company and process some Longteng for them. The key components of gearbox products are the main source of orders for our factory in the early stage. In the future, we will actively expand cooperation units across the country, relying on our factory's technical equipment and strength, and strive to obtain more orders..."
