004 Complex stainless steel parts

Regarding Yun Fei's life experience, Boss Wang and Liu Yushui were both curious.

Liu Yushui also knew that if Yun Fei was really as he said, he wouldn't be able to afford him at all, and he would bury him here. He was really curious, who cultivated such a child, and why would he go to Shenzhen and apply for a job as a worker in a workshop like his own?

Out of curiosity about Yun Fei, Liu Yushui cheekily followed Boss Wang's Santana.

In the car, He Fei learned that Boss Wang's name is Wang Qingfeng, his hometown is in the Northeast, and he belongs to the first group of people to go to the sea. Because of the mechanical factory repair worker, he originally planned to go to Shenzhen to do a small business, found that there are a lot of mechanical parts in many factories in Guangzhou that need to be processed, he raised more than 10,000 yuan, spent thousands of yuan in the original unit "bought" a second-hand lathe, transported to Guangzhou and began to engage in machining and maintenance business.

After ten years of development, it is now a factory with 40 ordinary horizontal lathes, 8 planers, 5 milling machines, 3 grinding machines, and more than 10 drilling machines. The processing strength is still quite strong. However, there are not many skilled masters in the factory, and many accessories are some relatively simple parts with low precision requirements, and the development has tended to come to a standstill in recent years.

When Wang Qingfeng's secretary and lover Zhang Rui (which Yun Fei didn't know about Lu Dao until half a year later) at ten o'clock the next night, I don't know how many times Lu Dao urged a few people to eat, there was a laugh of the three people in the office.

"Brother Yun, sure enough, it was the back waves of the Yangtze River pushing the front waves, admiring ......" When he came out, Liu Yushui praised Yun Fei with a smile on his face. After talking to Yun Fei for a few hours, he has gained a lot of insight from the old fritter, who has been a boss for more than a year.

"Brother Yun, tonight, if our brothers don't get drunk and don't go home, how about we talk about work while eating? Rest assured, it will definitely meet your requirements. Wang Qingfeng had to thank God for sending such a baby bump to himself at this time.

Under the leadership of Secretary Zhang, several people walked to a small restaurant not far from the factory and began to eat and drink.

Secretary Zhang was very curious about what the few people were talking about in the office, and why these two middle-aged people were so polite to a child. After the most lu, Liu Yushui, who drank high, learned the truth.

As soon as he entered the office, Wang Qingfeng couldn't wait to take out a blue A1 drawing. That's the blueprint for cloud non-requirements. Except for Arabic numerals, all of them are marked in English.

Yun Fei spread out the drawings on Wang Qingfeng's desk, lowered his head and looked at them intently, but Wang Qingfeng and Liu Yushui couldn't read the English on the drawings, so they could only stare at Yun Fei dryly.

Secretary Zhang couldn't read the drawings at all, and when he saw a few people staying here dryly and feeling bored, he left the office and went to order food in the small restaurant next to him.

Yun Fei watched for more than ten minutes before he raised his head, and couldn't help laughing when he saw Wang Qingfeng and Liu Yushui staring at him nervously.

took out the cigarette in his trouser pocket, handed it to the two, and lit it himself before he began to tell the two in detail about the processing difficulties of the parts on this picture.

"The first difficulty in processing this part is the material. Due to its own characteristics, 304 stainless steel is hard and cotton, which is a difficult material to process. In our country, most of the workers have not encountered it, whether it is with YG series or YW series tools, it is more difficult. The situation is much better abroad, and their CNC lathes can easily ensure the accuracy of the parts when processing large quantities of stainless steel products. ”

After the young Yun Fei said these words, he picked up the teacup on the desk and drank all the tea that had been in the middle for an unknown amount of time. Wang Qingfeng didn't care about Yun Fei's own cup, and when he saw him finish drinking the water in the teacup, he immediately picked up the thermos next to him and filled the teacup.

"The most important problem is that most of the tolerances have high precision requirements, and they are also thin-walled parts, with a diameter of more than 230 and a unilateral thickness of only three millimeters, and the amount of deformation is difficult to control."

After Yun Fei said the biggest difficulty in processing this part, he paused and continued.

"If it is a single piece or small batch production of ordinary cars, there is no problem, but this drawing requires 100 products to be delivered within a month, if there are no five or six CNC lathes, it will not be done at all."

Yun Fei's analysis made the two people next to him nod their heads constantly. Wang Qingfeng was not born in machining, but he is still familiar with stainless steel.

Liu Yushui will not say, he is a lathe worker, although stainless steel has not been done, but I have heard that this is a very difficult material to process, for thin-walled parts, he has done a lot, for this kind of deformation and difficult to process the material to do thin-walled parts, he Liu Yushui only has a headache.

"There are two CNC lathes, and this batch of work is because the other party knows that we have CNC equipment and asked us for a quotation. But I haven't opened it since I bought it. Because I bought second-hand equipment from Germany, I didn't have training, and I haven't found the right person for maintenance, and I don't know if it can be used. ”

"What about the skills of the workers in the factory? How many turners are there above grade 6? Yun Fei had to sigh, in this era, the development status of the domestic machinery processing industry.

Since there is no advanced equipment, it can only rely on the technical level of the workers. In China, the complex products processed by high-tech workers are no worse than foreign CNC equipment, and the only thing is that the efficiency is too low.

"Yang Dezhi is the only one in the factory who is an eighth-level lathe, but he has never touched stainless steel at all. There are four or five sixth- and seventh-level lathe workers, all of whom are masters who were laid off from our original factory and came here with me. Most of the rest are apprentices recruited after the factory is built, you know, there are not many mechanical state-owned enterprises here, even those skilled workers laid off in heavy industrial cities, very few come here. ”

Yun Fei's head is big, and the clever woman can't cook without rice. Without equipment and a large number of high-skilled workers, this piece of meat seems to be really inedible in the mouth.

Speaking of workers, Wang Qingfeng and Liu Yushui both had headaches. Here, although most of the work accuracy requirements are not high, the technical level of workers is not high, as long as you learn the basic operation, you can independently open the machine tool after separating the process. Even if there are laid-off workers from state-owned enterprises who are skilled and skilled, they will be poached by those foreign-funded enterprises with high salaries.

"How much is the processing fee for each piece?" As for which country the customer is, which company it is, Yun Fei simply doesn't care. For him, no matter how difficult the parts are to be machined, as long as the price is enough, he can make them, even if they are filed with a file.

"Four hundred pieces a piece." Speaking of this processing fee, Wang Qingfeng was excited. But it was eclipsed in an instant, such a fat meat, you can only look at it, you can't eat it in your mouth.

"How much?" The number in Wang Qingfeng's mouth shocked Liu Yushui.

He knew that the processing cost of this job was high, but he didn't expect the processing fee to be so high. You must know that the salary of a skilled worker is only 300 yuan, and the processing fee for such a product alone has reached 400 yuan. What a profit there must be!

"The price is too low, but you better take me to the workshop to see the equipment first, and you have to look at the equipment to determine whether it can be done."
