Smart Industrial Empire

() Arriving at the CNC workshop, Yunfei's depression in the machining workshop was swept away.

The CNC workshop not only has a large space, but also the installation of each piece of equipment is reasonable. Most importantly, since the first three CNC machine tools were in operation, Yunfei has been strict with the workers he trained himself.

For Qingfeng Machinery, the CNC operators traded from Kamart are a considerable fortune.At least, most of those CNC workers who have received systematic training have largely solved Qingfeng Machinery's demand for skilled CNC cao workers in the initial period of time, making these equipment move from Kamart to Qingfeng Machinery , there is a benefit.If Kamart only needed to find a technician who was familiar with CNC machining technology, Qingfeng Machinery would not have taken advantage of this advantage.

The CNC machine tools of this era are not as fast and convenient to operate as those of later generations.The computer programming of later generations is almost still kept secret from mainland China.In the whole of China, there are not even a few computers.As for the cadcam software used in computer design and programming, there are not many people to be found.

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. Up to now, it is estimated that there are only a few machining centers in those research institutes. It is placed inside.Those so-called multi-axis machining centers are not really machining centers.

Even after 20 years, the real five-axis machining center still belongs to the top machine tools in the world.

If you can't buy high-end precision machine tools, of course there will be no supporting computer design software.Therefore, in the early 90s, more than 90.00% of China's CNC equipment was programmed manually.

Manual programming of complex parts places very high demands on CNC technicians.The processing of complex curved surfaces not only requires a large number of numerical calculations, but also requires a considerable understanding of the equipment.Technicians who can manually program complex parts cannot be cultivated 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 Kamart.He is a senior technician from the aerospace system, and somehow he was hooked up by Kamat Company, and Qingfeng Machinery was finally cheaper.

After entering the CNC workshop, Yunfei has never left this workshop, which has cost him countless efforts.

Since these numerical control equipment came from several ages and several countries, except for Yunfei who came from later generations and has a lot of knowledge about the numerical control systems of the United States, Japan, and Germany, no one really can play with them. Turn on all devices.

Even Yun Fei can only explore by himself with the foreign language materials in hand.

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

Although the two had worked on CNC machine tools in state-owned factories for several years, most of them were CNC machine tools purchased when China established diplomatic relations with Japan and the United States in the late 70s and early 80s.The CNC lathe is no problem for the two of them, but the complicated part programming of the CNC milling machine makes them a headache.

Many of the complex parts programming of CNC milling machines must be designed with complex CNC operations.Especially when the numerical control system is processing curved surfaces, the amount of Boolean operations that need to be performed is even greater.For the complex calculations of intersection, union, and difference between several geometric bodies or even dozens of geometric bodies, if there is a slight data error, or if there is a certain place that is not considered, the part will have to be scrapped.

For Boolean operations, Yun Fei, who is not good at mathematics, can't compare with Yang Guang and Feng Yumin, the first undergraduates after the resumption of the college entrance examination.

Although the calculation is not as good as these two people, but the calculation method knows more than these two people.Since these two guys arrived at Qingfeng Machinery two months ago, Qingfeng Machinery dared to accept no matter how complicated the parts were.Especially in the processing business of molds, countless complex cavities require a lot of calculations. In the era without computers and mathematics talents with professional backgrounds, it is unimaginably difficult.

After ten o'clock in the morning, when Yunfei was still instructing Yang Guang and Feng Yumin on the CNC machining process, Luo Xiaoli had already come and told him that Kamart Company drove several cars with a large group of The high-nosed foreigner has arrived at the factory and is now heading towards the CNC machining workshop.

Hearing that Kamart came with customers, Yun Fei didn't care to communicate with the two of them anymore, and hurried to the workshop door.The customer is God, and when God comes, he, the deputy director of the factory, should go to greet him no matter what.

Seeing Yun Fei at the door of the workshop, Wang Qingfeng, who was wearing a suit and tie, introduced to the crowd behind him.It is estimated that the translator was invited by Kmat Company, or the translators brought by these foreigners. For a while, English and German rang with Wang Qingfeng's words.

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

As soon as Yun Fei arrived at the entrance of the workshop, he met seven or eight white men in their 50s and [-]s, and it was unclear which country these foreigners came from.In this world, there are too many English-speaking countries.But when he heard German, which he could only know a small number of words, he understood that at least two or three of these foreigners came from Germany.

At the end of the 80s and the beginning of the 90s, the labor costs in 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 in mainland China, a large number of skilled workers in state-owned enterprises have been laid off for reemployment, and a large number of foreign companies have set their sights on this country whose labor costs are less than one-fifth or even lower than their own countries.

The first batch of foreign-funded enterprises set up factories in mainland China. Taking advantage of the low labor costs and tax-free policies of this populous country, they not only revived the parent company that was on the verge of bankruptcy, but also rapidly expanded their market share.This makes more foreign-funded enterprises and even large companies set their sights on mainland China.

"Mr. Yun, I've admired you for a long time! I'm Ren Zhiguo, the deputy manager of Kamat Company. These are customers from the United States and Germany. If we take them down, not only our company will benefit greatly, but also your Qingfeng Machinery. The scale is estimated to be large." Make it three to five times larger." Ren Zhiguo dared not look down on Yun Fei, a half-grown child who hadn't even 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 have given up any hope for this trip.If it weren't for the high-level executives of Kamat Company who highly praised this small machinery factory with no more than [-] pieces of equipment and workers in their early [-]s, they would not even be interested in understanding this company.If Kamart hadn't shown them the stainless steel thin-walled parts samples made by Qingfeng Machinery, how could they have agreed to inspect this small factory.

When I arrived at this factory, I realized that the owner of this factory didn't know anything about his own factory, especially in terms of technology; at this time, he actually told himself that a child of seventeen or eighteen years old was actually their chief engineer. Responsible for the technology of the entire factory!

"Hi everyone, welcome to visit the Chinese factory with the most modern management in China. During the visit, if you have any questions, as long as it does not involve commercial secrets, I will answer them in detail. Let's look at the CNC workshop first." Yun Fei finished. , ignoring those foreigners who looked suspicious and contemptuous, and walked towards the interior of the workshop.

On the far side of the workshop are the latest models, CNC equipment bought from Kamart.

"This is our latest CNC lathe and CNC milling machine from Germany and Japan. Of course, there is also a machining center from Fadal in the United States. We welcome your valuable opinions." Yun Fei introduced the CNC machining workshop to foreigners. Of course he knows that these equipments are considered high-precision machine tools in mainland China, but they are not even considered mid-range machines abroad.

However, Qingfeng Machinery will not tell foreigners about the fact that Qingfeng Machinery does not have computer-aided design software.

The appearance of a large group of foreigners with high noses and blue eyes did not stop the workers who operated the CNC machine tools from their work.While operating the machine tool, the workers used a micrometer to check the size of the last processed part in their spare time.

Seeing this, some foreigners nodded and shook their heads a little.

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

"Mr. Carlos, I have to say that I admire your keen observation. Please don't doubt that the behavior of our workers is not because they are not confident in themselves, let alone in the equipment. They are all through their own system. Trained skilled workers. The reason for doing this is to be responsible to our customers. Presumably you know better than me that the quality of CNC machine tools is stable when producing large quantities of workpieces. Our customers do not have high requirements for us, and often The tolerance range they gave us is 0.1mm or more, but we will control these tolerance ranges within 0.04mm, which will help customers to meet the interchangeability requirements of parts and improve the service life of parts, thereby improving our customers' market Competitiveness. Of course, this is mainly because of our need for stable business. I don’t think any company wants its customers to go bankrupt, which will affect its own development. What do you think!”

After Yun Fei finished speaking directly in English, Carlos couldn't help giving a thumbs up.And the other foreigners applauded.They did not expect that such a young Chinese could speak fluent English.

A 40-year-old German named Maxim didn’t believe Yun Fei’s words. He thought the young engineer was bragging, so he ran directly to a cao worker, picked up the micrometer on the workbench, and began to measure the production. good parts.

After sampling the parts of a cao worker, he sampled and inspected almost every part produced by the cao worker. In the end, he had to give a thumbs up.Because, among all the parts he sampled, the error of the same type of parts in the same batch did not reach the 0.04mm that Yunfei said, but only less than 0.01mm.

In Germany, under mass production, it is difficult for workers to control the error to such a small range.

"Mr. Yun, please forgive me for my doubts about you earlier. Your workers are all the most skilled workers in the world." Yun Fei admired the seriousness of the Germans.

Although foreigners secretly laugh at these so-called state-of-the-art machine tools produced by Qingfeng Machinery Factory, they still admire the quality of the parts processed by these CNC equipment.
