When he arrived at the CNC workshop, Yun Fei's depression in the machining workshop was swept away.

The CNC workshop not only has a large space, the installation of each equipment is reasonable, and the most important thing is that from the very beginning of the operation of the three CNC machine tools, Yun Fei has strict requirements for these workers trained by himself.

The CNC operators traded from Camat Company are a lot of wealth for Qingfeng Machinery. At least, most of the CNC workers who have been systematically trained have largely solved the needs of Qingfeng Machinery for skilled CNC operators in the initial period of time, so that these equipment have produced benefits since the Camat company moved to Qingfeng Machinery. If Camat only needs to find a technician who is familiar with CNC machining technology, then this advantage will not be taken advantage of by Qingfeng Machinery.

The CNC machine tools of this era are not as fast and convenient to operate as those of later generations. Later generations of computer programming were almost still in a state of secrecy from Chinese mainland. In the whole of China, there are not even a few computers. For the CAD/CAM software used in computer design and programming, it is even more difficult to find a few people.

In this era, due to the existence of the Batumi embargo, the degree of openness of CNC equipment to the Chinese market is still very low, especially high-end precision machine tools, until now, it is estimated that only a few machining centers are placed in those research institutes. Those so-called multi-axis machining centers are not really machining centers.

Even 20 years later, the true 5-axis machining center is still one of the world's top machine tools.

If you can't buy high-end precision machine tools, of course, there will be no supporting computer design software. Therefore, in the early nineties, more than 99% of China's CNC equipment was manually programmed.

The manual programming of complex parts is very demanding for CNC technicians. The processing of complex surfaces not only requires a lot of calculations, but also requires a considerable understanding of the equipment. Technicians who can program complex parts by hand are not something that can be trained in just a few months.

Yang Guang, who was promoted by Yun Fei as the director of the CNC workshop, was one of the two CNC engineers of the original Kamat company. is a senior technician who came out of the aerospace system, and I don't know how Lu Dao was hooked up by Camat Company, and Qingfeng Machinery was cheaper after the end.

Since arriving at the CNC workshop, Yun Fei has never left this workshop that has cost him countless efforts.

Because these CNC equipment comes from several generations and several countries, so, in addition to coming from later generations, Yun Fei, who has a lot of understanding of the CNC systems of the United States, Japan and Germany, really no one can play with all the equipment.

Even Yun Fei can only rely on the foreign language materials in his hand to explore by himself.

As soon as he entered the CNC workshop, Yun Fei was entangled by Yang Guang and Feng Yumin, another CNC engineer from Kamat.

Although the two have worked in the state-owned factory for several years of CNC machine tools, most of them are CNC machine tools purchased in the late 70s and early 80s when China established diplomatic relations with Japan and the United States. CNC lathe, for the two of them is no problem, but the complex parts programming of the CNC milling machine makes the two of them a headache.

Many of the complex parts programming of CNC milling machines must be designed to complex CNC operations. Especially for surface machining, the amount of Boolean operation that needs to be calculated is even larger. For the complex operation of intersection, union, and difference between several geometries or even dozens of geometries, if the data is slightly wrong, or there is a certain place that is not considered, the part will have to be scrapped.

Unlike later generations, there are a wide variety of CAD/CAM software, as long as the CAD software is used to complete the modeling of the part, and then the CAM software is used to automatically calculate the parts that need to be processed, the software will automatically generate the program.

For Boolean operations, Yun Fei, who is not good at mathematics, is not as good as Yang Guang and Feng Yumin, the two undergraduates in the first class after the resumption of the college entrance examination.

Although the calculation is not as good as these two people, the calculation method is more than these two people. Since these two guys arrived at Qingfeng Machinery two months ago, Qingfeng Machinery dares to take on parts no matter how complicated they are. Especially in the mold processing business, countless complex cavities require a lot of calculations, which is unimaginably difficult in the era when there are no computers and no mathematical talents with professional backgrounds.

After ten o'clock in the morning, when Yun Fei was still instructing Yang Guang and Feng Yumin on CNC machining technology, Luo Xiaoli had already come to him and told him that Camat Company had driven several cars and brought a large group of high-nosed foreigners to the factory, and was now coming towards the CNC machining workshop.

Hearing that Camat Company was coming with customers, Yun Fei didn't care about communicating with the two anymore, and hurriedly walked towards the door of the workshop. The customer is God, God is coming, and he, the deputy director, should go to greet him no matter what.

Seeing Yun Fei arrive at the door of the workshop, Wang Qingfeng, who was wearing a suit and tie, introduced himself to the group of people behind him. It is estimated that it was the translator invited by the Cammat company, or the translator brought by these foreigners themselves, and for a while, English and German were ringing with Wang Qingfeng's words.

"Ladies and gentlemen, this is Yun Fei, the chief engineer and deputy director of our Qingfeng Machinery. If you have any questions during the visit, you can directly ask Mr. Yun for information. ”

As soon as Yun Fei arrived at the door of the workshop, he met white people in their forties and fifties with seven or eight years old, and he couldn't tell which country these foreigners were from. There are too many English-speaking countries in this world. But when he heard German, a word he could only know a few words, he understood that at least two or three of these foreigners were from Germany.

In the late eighties and early nineties, the labor cost of the whole Europe and the United States increased significantly, and the blowout development of their CNC industry was born in this environment. With the reform and opening up of Chinese mainland, a large number of skilled workers in state-owned enterprises have been laid off and re-employed, and a large number of foreign enterprises have set their eyes on this country where the labor cost is less than one-fifth or even less of their own country.

The first batch of foreign-funded enterprises to build factories in Chinese mainland, taking advantage of the low labor costs and tax exemption policies of this populous country, not only brought the bankrupt parent company back to life, but also rapidly expanded its market share. This has led more foreign-funded enterprises and even large companies to set their sights on Chinese mainland.

"Mr. Yun, it's been a long time! I am Ren Zhiguo, the deputy manager of Cammat. These are customers from the United States and Germany, if they are taken down, not only our company has unlimited benefits, but also your Qingfeng machinery, the scale is estimated to expand by three or five times. Ren Zhiguo didn't dare to despise Yun Fei, a half-grown child who hadn't grown a beard yet.

Hearing the translator's introduction, several foreigners opened their mouths in surprise. Such a young chief engineer can only appear in China, a country with a red regime!

Now they don't have any hope for this trip. If it weren't for the fact that the top management of the Camat company admired this small machine shop in its mid-200s, which had no more than 100 pieces of equipment, they would not even be interested in learning about the company. If it weren't for the fact that Cammat showed them a sample of the stainless steel thin-walled parts made by Qingfeng Machinery, how would they have agreed to inspect this small factory?

When he arrived at this factory, he found that the owner of this factory did not know anything about his own factory, especially in terms of technology; At this time, he actually told himself that a seventeen or eighteen-year-old child was actually their chief engineer, responsible for the technical skills of the entire factory!

"Hello everyone, welcome to visit the most modern management of China's factory. During the visit, if you have any questions, as long as it does not involve trade secrets, I will answer them in detail, let's look at the CNC workshop first. After Yun Fei finished speaking, he ignored the foreigners with suspicion and contempt, and walked towards the inside of the workshop.

At the very edge of the workshop are the latest models, CNC equipment bought from the Cammat company.

"This is our latest purchase of CNC lathes and CNC milling machines from Germany and Japan. And, of course, there are machining centers from FADAL in the USA. We welcome your valuable comments. Yun Fei introduced the CNC machining workshop to the foreigners, of course, he knew that these equipment are high-precision machine tools in Chinese mainland, but in foreign countries, they are not even mid-range.

However, Qingfeng Machinery does not have computer-aided design software, and he will not tell foreigners.

The appearance of a large group of high-nosed and blue-eyed foreigners did not stop the workers who operated the CNC machine tools. While operating the machine, the workers use the micrometer to check the size of the last machined part in their spare time.

This made the foreigners nod their heads and shook their heads a little.

"Mr. Yun, I'm Carlos from the United States. For the workers of your company, so frequently check the size of the processed parts, I would like to ask you, is this your company's workers are not confident in themselves, or for these CNC machine tools? A tall and thin white man in his fifties suddenly asked Yun Fei.

"Mr. Carlos, I have to say that I am impressed by your keen observation. Please do not doubt that the behavior of our workers is not because they are not confident in themselves, let alone in the equipment. They are all skilled workers who have been systematically trained by themselves. We do this because we are responsible for our customers. You must know better than me the stability of quality when CNC machines produce large quantities of workpieces. Our customers do not have high requirements for us, often they give us a tolerance range of 0.1mm or even more, but we will control these tolerance ranges within 0.04mm, which is conducive to the customer's interchangeability requirements for parts and improve the service life of parts, so as to improve the market competitiveness of our customers. Of course, this is mainly due to our need for a stable business. I don't think any company wants its customers to go bankrupt and affect its own development. What do you think? ”

After Yun Fei said this sentence directly in English, Carlos couldn't help but give a thumbs up. And the other foreigners applauded. They did not expect that such a young Chinese would actually speak fluent English.

A German in his forties named Maxim didn't believe Yun Fei's words, thinking that the young engineer was bragging, ran directly to an operator, picked up a micrometer placed on the workbench, and began to measure the parts that were produced well.

After sampling an operator's parts, almost every operator produced good parts, to the worst, he had to give a thumbs up. Because, among all the parts he sampled, the error of the same batch of the same kind of parts did not reach the 0.04mm that Yun Fei said, only less than 0.01mm.

In Germany, it is also difficult for workers to control the error to such a small range under high-volume production.

"Mr. Yun, please forgive me for my previous doubts about you. Your workers are the most advantageous skilled workers in this world. The seriousness of the Germans made Yun Fei admire.

Although the foreigners are secretly amused in their hearts about these so-called state-of-the-art machine tools of Qingfeng Machinery Factory, they are still very impressed by the quality of the parts processed by these CNC equipment.
