Only 20 years ago, Ha Ling City in Jingnan Province was still a predominantly agricultural city, of course, at that time it was not called Ha Ling City, but called Ha Ling District.

It may be because it is located on the southeast coast, and belongs to the front line in the era of preparing for war and famine, and the state does not dare to lay out too many industrial projects here, and there are less than 100 industrial enterprises in the entire Heling area, and most of them are small factories with only a few dozen or even a dozen people, doing some non-staple food processing or agricultural machinery repair business, which is a negligible part of the country's industrial system.

Due to the large number of people and the lack of land, the agriculture of Heling is actually not developed. The local rice production is not enough to feed the farmers in the region, who depend on sweet potatoes for most of the year, and only enough to feed themselves.

There is a joke in Jingnan Province that if the people of Heling go to the provincial capital Yuyuan to do business, they don't need to introduce themselves, and people only need to look at their yellow-skinned and thin image, they can guess their origins, and they are basically eight or nine.

If you are poor, you will think about change, this is an eternal truth. Even in the years when the state restricted the development of the private economy, the people of Heling still secretly engaged in all kinds of small businesses, such as going from village to village, exchanging some home-made maltose for other people's chicken feathers and other waste products, and then selling them to state-run scrap collection stations to earn a small difference.

The people who had been arrested for "speculation" for doing this kind of business were able to make up a few regiments in Heling, so much so that decades later, the local private bosses of Heling got together to drink and talk about the past, and there were not a few people on the table who had not sifted the sand.

In the early 80s, the state began to loosen the restrictions on the private economy, and the business genius cultivated by the people of Heling in the long-term small business got a chance to display. In just a few years, thousands of small industrial enterprises have appeared in Heling, and these enterprises were all dressed up as "village-run enterprises" and "socially-run enterprises" at the beginning, but gradually revealed their original forms, and all of them were private enterprises founded by farmers themselves or in partnerships.

By the end of the 90s, Heling had become a nationally renowned metal products manufacturing base, with hundreds of products producing more than half of the world's total. Almost every village in the city has a number of enterprises, and in some villages, even every household is a business owner. Large tracts of farmland were occupied and factories were built. Some of the scattered plots are also only used to grow vegetables, and no one is interested in growing food anymore.

The development of the manufacturing industry has brought a huge demand for machine tools. In the urban area of Heling, you can see all kinds of machine tool sales points and maintenance points everywhere, some stores only operate a certain brand of machine tools, and some are operating a certain type of machine tools. Because of the large number of machine tool sales points and maintenance points, when a maintenance shop called "Fat Machine Tool" opened in Heling City, except for the shops in the neighborhood came to see the excitement, no one else felt that there was anything new.

The machine tool repair shop co-opened by Ning Mo and his co-worker Lai Taotao uses the name "Fat Machine Tool" mainly to increase recognition. Other stores use signs such as "Xin" and "Long", which sounds quite auspicious in isolation, but when there are more than a dozen "Xin" on the same street, customers will inevitably have aesthetic fatigue. It is also common for repeat customers to go to the wrong store, which shows the lack of recognition of the sign.

Fat Machine Tool is a double husband-and-wife shop, Ning Mo's wife Zhang Beibei works as an accountant in the store, Lai Taotao's wife Liu Xiaojing works as an administrator in the store, and Ning Mo and Lai Taotao are maintenance workers in the store.

Ning Mo chose to start a business in Heling because he had previously been sent to Heling by the factory to cooperate with Zhao Xinggen and Zhao Xingwang's brothers Longhu Machinery Factory. Through the Zhao brothers, Ning Mo got to know many local private business owners in Heling and formed deep friendships with them at the wine table.

Ning Mo has been instructed by famous teachers in the factory over the years, fitter skills are more exquisite than many forty or fifty-year-old masters, coupled with integrity and boldness, some private business owners have promised him that as long as he comes to Heling to open a shop, if the machine tool in his factory fails, he will definitely give priority to him to help repair.

After the opening of the fat machine tool shop, the owners of these private companies did not break their promises, gave them a lot of maintenance orders, and were not too picky about the price. In the past few months, the net profit of the fat machine tool has exceeded 100,000, Zhang Beibei counts the money every day and has cramps, with an idiotic smile on her face 24 hours a day, in other words, her belly is getting bigger and bigger, and the fat man is about to become a father.

On this day, a group of uninvited guests came to the fat machine tool shop, and even Ning Mo and Lai Taotao specially pushed down the orders of several customers and stayed in the store to receive these people. However, it was not the two shopkeepers who were in charge of the reception, but Han Weichang, the former sales minister of Linyiji.

"Mr. Ye, come and see, this is a new type of mold machine tool jointly launched by our Linyi machine and Teng machine, and we named it an engraving and milling machine. It is characterized by engraving instead of milling, which is most suitable for precision mold processing. ”

Han Weichang pointed to an ordinary-looking machine in the middle of the store hall and introduced it to Ye Yongfa, chairman of Xinta Mold Company. After that, he also greeted the people who followed Ye Yongfa, who were also the bosses of some manufacturing enterprises in Jingnan, but the scale of the enterprise was not as large as that of Xinta Mold Company, and in Ye Yongfa's presence, Han Weichang did not greet them alone, which was not rude.

The idea of transforming a wood carving machine tool into a mold machine tool originated from Xiao Wenjun. Due to the experience in the design of wood carving machine tools, a group of engineers from the Canglong Research Institute worked together and it took a short time to design the engraving and milling machine specially used for fine metal carving.

Although the engraving and milling machine is a fist product specially designed for Tengji, Tang Zifeng did not immediately hand over the product to Tengji to manufacture, but arranged for Linyi Machine to conduct trial production first. The prototype manufactured by Linyi Machine was iterated in five versions, and finally finalized, which is now placed in the fat machine tool shop.

A carving and milling machine weighs nearly one ton, and Han Weichang wants to recommend this kind of engraving and milling machine in Jingnan, so naturally he can't run around with such an iron lump on his back. He knew that Ning Mo had opened this machine tool repair shop in Heling, so he discussed with Ning Mo and put the engraving and milling machine in the fat machine tool shop.

Of course, there is also a fee for using the premises of the fat machine tool shop. Han Weichang handed over this business to the fat machine tool shop, and he had some intention of taking care of Ning Mo, because Lao Han knew that the relationship between Ning Mo and Tang Zifeng was not an ordinary intimacy.

"Is there any benefit to replacing milling with carving?" Ye Yongfa looked at this unattractive machine tool and asked lightly.

"Mr. Ye, look at it, this is a sample we carved. ”

Han Weichang took a silver glittering workpiece from Ning Mo's hand and handed it to Ye Yongfa's hand.

"Well, it's not bad, the surface finish is quite high, and the arc is quite smooth. However, with the machining center we are using, we can also process this effect, your machine tool, is too small, you can't process some large pieces, right?"

Ye Yongfa fiddled with the artifact in his hand and commented.

Our kind of engraving and milling machine is mainly for small workpieces, that is, 80 by 80. ”

Han Weichang first complimented Ye Yongfa, then smiled mysteriously and asked, "However, Mr. Ye, didn't you find anything special about this artifact?"

"Special?" Ye Yongfa was stunned, he looked at it seriously, shook his head and said, "It's nothing special, isn't it just a square, it's just a few cuts on the face." ”

Han Weichang pointed his finger and said, "Mr. Ye, take a serious look at this place." ”

Ye Yongfa looked at it again with round eyes, but still shook his head and said, "I don't see anything special." ”

Han Weichang stretched out his hand to take the workpiece, and pressed it a little the place he just pointed to, and a magical thing happened, that place actually sank, and the whole workpiece became two pieces at once.

"It's actually put together!"

Not only Ye Yongfa, but everyone else was also shocked. Although they didn't get started just now, they were not far away, and they could see the condition of the artifact clearly. Before Han Weichang started, this workpiece was clearly a whole piece, and there was no gap on it anyway.

And now, with a press by Han Weichang, the workpiece is separated. Where is this whole piece of workpiece, it is clearly assembled in two pieces, the upper one has several holes, and the lower one has several convex cylinders, and the cylinders are sleeved in the holes, tightly sealed, and it looks like a whole.

What a high level of machining accuracy!

Of course, it is possible to produce such high-precision workpieces using precision milling machines, but they are generally limited to machining on a specific plane. This kind of precision machining, which is both a hole and a cylinder, if it is to be achieved on a precision milling machine, is enough to make a good miller collapse.

"This is what this engraving and milling machine is made of?" Ye Yongfa pressed the excitement in his heart, pointed to the engraving and milling machine and asked Han Weichang.

"Exactly. ”

"Is it difficult?"

"It's not difficult. ”

"Can you show us a demo?"

"Absolutely. ”

Han Weichang said and gestured to Lai Taotao on the side. Lai Taotao didn't know where to take out a rough blank with a rough surface, walked to the engraving and milling machine, skillfully opened the protective cover of the machine tool, clamped the blank to the workbench, and then closed the protective cover. Then, he pressed a bunch of buttons on the control panel, the machine beeped, and the engraving head in the protective cover began to cut through the workpiece.

Everyone came forward and observed the machining process inside through the transparent machine cover. These people are all from mechanical backgrounds, although they have never seen this kind of engraving and milling machine, but at a glance, they also understand what its working principle is. The engraving and milling machine is actually a milling machine, but it uses a small cutter head to highlight the fine machining. Due to the single function, its machining accuracy can be effectively improved, and the difficulty of operation is also reduced, which is its advantage over ordinary machining centers.
