In fact, Xiao Wenjun is a typical "black under the lamp", and the wood carving machine tool of Linyi Machine was designed by her, and this design brought her millions of patent fee income, making her from a poor college student who went to lecture and save money to buy a notebook, and became an invisible rich woman on the campus of Tsinghua University. According to her own guess, she is likely to be the richest man among Tsinghua students, unless there are other bigwigs as low-key as her.

A few days ago, when she was thinking about a new idea for a mold milling machine, she vaguely felt that she had an idea in her head, but she couldn't grasp it. She was limited by the routine of traditional machining centers, and always wanted to innovate under this concept. And all the ideas she can think of, the designers of large foreign companies have already thought of them, and they have registered patents, which makes her scratch her ears and cheeks, and she has no idea where to start.

Standing in the furniture exhibition hall just now, touching the patterns on the wardrobe door, she suddenly realized that her thinking these days has completely gone astray. Mold manufacturing is actually carved on the metal surface, and the idea of directly applying the wood carving machine tool is good, why should you be confined to the design routine of the machining center?

In principle, a wood carving machine tool is also a milling machine. When she first designed the long tassel wood carving machine, she referred to the design of the copy milling machine. However, with the improvement of the long tassel wood carving machine tool again and again, the difference between it and the traditional milling machine gradually emerged, that is, the emphasis on the use of small cutter heads for fine processing, which strengthened the concept of "carving".

Of course, conventional machining centers can also be used for fine machining with small cutter heads, but their main function is milling over a large scale. In mold processing, if the scale of the mold is large and the details are not high, it is more appropriate to use a machining center, and its processing efficiency is higher. However, in recent years, consumer goods are becoming more and more refined, and the requirements for the refinement of molds are getting higher and higher, and traditional processing methods are somewhat unsuitable.

For example, in the past, cups made of resin were smooth from top to bottom, and the design and processing of molds were very simple. In recent years, resin cups with patterns or words on the surface have begun to appear on the market, of course, these patterns or words cannot be carved in the later stage, but can only be carved at the time of mold manufacturing, and one-time injection molding during production.

To make such molds with patterns or words, fine processing is involved. Using a traditional machining center to carry out this kind of fine processing can be said to be an anti-aircraft gun to fight mosquitoes, not that it cannot be defeated, the key is that the efficiency is too low, and many capabilities are completely wasted.

Xiao Wenjun's original design idea is to improve the fine processing capacity of the machining center, which means that the same machining center must not only be able to carry out large opening and closing milling operations, but also meet the fine processing requirements of hair carving, the result is naturally to increase the design difficulty of the machine tool, and greatly improve the production cost of the machine tool, and finally lose the price advantage.

Foreign machining centers take this path. They don't care about the cost, they can do both. Anyway, users love to buy or not, if you don't buy their equipment, you can't make precision molds, and you will lose the high-end mold market. There is a price difference between ordinary molds and high-end molds, and it is reasonable to make excess profits by manufacturing high-end molds, and machine tool manufacturers take a share of these high profits.

The upgrading of consumer goods is a process of collecting luxury tax. For example, a teacup is used to drink water, as long as it can hold water, it is a qualified teacup. If the manufacturer is satisfied with making a container for water, then they will not make money, and if they want to make a lot of money, they must make all kinds of articles on the teacup, such as changing the artistic shape, carving a dream of red mansions on the teacup.

To make a teacup with engraved words, more advanced materials are needed, special machine tools are needed, and special designers are needed to be able to feed a large number of people, and the final product is still just a cup filled with water, which does not bring any new benefits to consumers.

The per capita GDP of Western countries was once dozens of times that of China, which does not mean that Western people eat big fish and meat every day, and a large amount of GDP is reflected in these luxury taxes. A paper clip from a top international luxury brand can be sold for dozens of dollars, and in the final analysis, there is too much money, and it will not work if you don't toss it like this.

At the beginning of China's opening up, it mainly undertook labor-intensive industries transferred from abroad and produced some low-end consumer goods, so the requirements for molds were relatively low. With the production of low-end consumer goods completely surrounded by Chinese enterprises, self-competition is becoming more and more fierce, profits are getting thinner and thinner, some enterprises that have completed the original accumulation of capital have begun to enter the high-end consumer goods market, the grade and quality of Chinese manufacturing are constantly improving, and with it, there is a huge demand for high-end molds.

Ye Yongfa's new tower mold company, in the early years, was a low-end mold, which is very appropriate to describe it as stupid, big and black. In recent years, Xinta company began to turn to high-end mold manufacturing, and the biggest obstacle encountered was the mismatch of machine tools.

To manufacture high-end molds, you need high-end machine tools. The high-end machine tool market is basically monopolized by foreign machine tool giants, and the machine tools produced by others have good performance and high processing accuracy, but the price is also ridiculously high. Ye Yongfa calculated that if imported machine tools were used to produce molds, the profits he earned on the molds would not be a penny left, and they would all be given to foreign machine tool manufacturers in vain.

Because of this, Ye Yongfa found Han Weichang, hoping that domestic machine tool companies can provide him with machine tools suitable for fine processing and low price. In addition to Xinta Company, Jingnan, Mingxi and other coastal provinces with developed processing industries, there are many similar mold enterprises that also have the same demand. According to rough estimates, this market can provide at least 500 million yuan of demand a year, and this number is growing rapidly.

The market is tempting, but it also requires excellent products to win this market. Tang Zifeng handed over the information brought back by Han Weichang to the Canglong Research Institute, and a group of engineers worked hard to give full play to the spirit of making a dojo in the screw shell, and tried to find a way to solve the "impossible triangle" of performance, quality and cost.

So far, Canglong Research Institute has achieved certain results. The engineers have made a number of improvements to the original CNC milling machine of Tengji, and it has barely been able to reach the degree of cost performance higher than that of imported machine tools. But the concept of cost performance, in fact, is not convincing, for Ye Yongfa these people, for better performance to spend an extra 10,000 yuan is not unacceptable, if the performance of the milling machine is too much worse than the imported milling machine, just the price is cheap, it is difficult to impress these people.

Xiao Wenjun is precisely because he knows this, so he has always been dissatisfied with the original design idea. She felt that there should be another way of thinking, which could perfectly circumvent the current obstacles and make a revolutionary breakthrough.

Replacing milling with engraving is a new idea found by Xiao Wenjun. By completely removing the large-scale milling function of the original machining center and focusing on fine engraving, the structure of the machine tool can be greatly simplified. And because the machine only does one job, the quality of that work can be greatly improved, which is much better than integrating all the functions in the same machine.

As for whether separating milling and engraving will lead to a waste of labor, who cares?

Thinking about this, Xiao Wenjun still had the heart to look at any furniture. She urged Tang Zifeng to drive home, then plunged in front of the computer and began to draw. The wood carving machine tool was designed by her, and now it is necessary to shift from carving wood to carving metal, which is nothing more than increasing the rigidity of the machine tool, improving the power of the spindle and servo motor, etc., for Xiao Wenjun, it is really familiar with the road.

Of course, there are many things to consider. For example, the engraving operation needs to improve the flexibility of moving parts such as workbenches and skateboards, which requires that the weight and volume of these parts are not too large, which will inevitably affect their rigidity. How to balance between flexibility and rigidity reflects the level of a scholar.

"Zifeng, this kind of machine tool should be distinguished from the traditional CNC milling machine, what do you think is the good name?"

Xiao Wenjun was drawing pictures while chatting with Tang Zifeng in a hurry. The problem of design ideas is solved, and the rest of the things are not a problem for Xiao Wenjun, so she can still use it for two purposes.

Of course, she is mainly worried that she will focus on design and will snub Tang Zifeng, which will cause trauma to her boyfriend's fragile psyche. This is also the warning of her roommates, as a female doctor, if you don't pay attention to this problem, the consequences will be very serious. Since knowing this theory, Xiao Wenjun has constantly reminded himself to talk to Tang Zifeng often, and he can no longer be distracted as soon as he draws a picture like in the past.

"Let's call it a carved bed. Tang Zifeng was engaged in a fierce battle with enemies from four different civilizations in front of another computer, and replied without looking back.

In fact, female doctors think too much, and the best way to stabilize their boyfriend is to give him a computer that can play games, and keep silent while he is playing games. For a man who is playing a game, there is nothing more devastating than his girlfriend's chatter.

"But my current design still needs to retain a certain milling function, not pure engraving. ”

"That's called a carving and milling machine. ”

"I think the name makes people mistakenly think it's a milling machine, and the engraving is easy to overlook. ”

"It is called CNC engraving and milling, multi-functional, cost-effective, reliable quality, and special precision machine tools for three-pack mold processing. ”

"If you have the ability, you can say it again and see if you can say it. ”

"If you say it a few more times, you won't string it, and it's cool to have a longer name, like Hato...... Uh, Bodo fifty-six. ”

"What does this man do?"

"A Japanese admiral. ”

"I think it's better called an engraving and milling machine, what do you think?"

"This name is good, daughter-in-law, you are really a master of choosing names, and our baby's name will be yours in the future. ”

"Tang Zifeng, you are really ashamed of the liberal arts students!"
