In fact, Xiao Wenjun is a typical "dark under the light". She designed the wooden carving machine tool of Pinyi Machine, and this design brought her millions of patent fees, allowing her to go from a poor college student who was hard to teach and save money to buy notebooks to become an invisible rich woman on Tsinghua campus. According to her own guess, she is likely to be the richest among Tsinghua students, unless there are other low-key big shots like her.

A few days ago, when she was thinking about new ideas for mold milling machines, she vaguely felt that she had an idea in her mind, but she could not grasp it. She was restricted by the routine of traditional machining centers and always wanted to innovate under this concept. However, any ideas she could think of were already thought of by designers from large foreign companies, and had registered patents, which made her scratch her head and unable to start.

Standing in the furniture exhibition hall just now, touching the patterns on the wardrobe cabinet door, she suddenly realized that her ideas have gone completely wrong these days. Mold manufacturing is actually carving on the metal surface, and it is better to directly apply the idea of ​​a wood carving machine tool. Why do you have to confine yourself to the design routine of the machining center?

In principle, wood carving machine tools are also a kind of milling machine. When she first designed a long tassel wood carving machine, she referred to the design of a contour milling machine. However, with the repeated improvements of the long tassel wood carving machine, the difference between it and traditional milling machines gradually emerged, which was that it focused on the fine processing of small cutter heads, strengthening the concept of "carving".

Of course, traditional machining centers can also be finely processed with small cutting heads, but their main function is milling processing within a larger scale range. In mold processing, if the mold has a large scale and low detailed requirements, it is more appropriate to use a machining center and its processing efficiency is higher. However, in recent years, consumer products have become increasingly more refined, and the requirements for fine-tuning of molds are getting higher and higher, and traditional machining methods are somewhat unsuitable.

For example, in the past, when resin was used to make a cup, it was smooth from top to bottom, and the design and processing of the mold were very simple. However, in recent years, resin cups with patterns or words on the surface began to appear on the market. Of course, these patterns or words could not be carved later, and could only be carved during the mold manufacturing and injection molding at one time during production.

To make such molds with patterns or text, fine processing is involved. Using traditional machining centers to perform this fine processing can be said to be an anti-aircraft gun to kill mosquitoes. It is not that it cannot be beaten down. The key is that the efficiency is too low and many abilities are completely wasted.

Xiao Wenjun's original design idea was to improve the fine machining capability of the machining center, which means that the same machining center must not only be able to perform large-opening and close milling operations, but also meet the fine machining requirements of carving on hair. The result is naturally increasing the design difficulty of the machine tool, and greatly increasing the production cost of the machine tool, ultimately losing the price advantage.

Foreign machining centers take this path. They don’t care about the cost, so they can naturally take care of both. Anyway, users like to buy or not. If you don’t buy their equipment, you will not be able to make precision molds and lose the high-end mold market. There is a price difference between ordinary molds and high-end molds. If you can make high-end molds, you can make excess profits. It is reasonable for machine tool manufacturers to get a share of these high profits.

The upgrade of consumer goods is a process of charging luxury taxes. For example, teacups are used to drink water, and as long as they can hold water, they are qualified teacups. If manufacturers are satisfied with making a container for water, they will not make money. If they want to make a lot of money, they must do various articles on the teacup, such as changing an artistic shape, engraving a Dream of the Red Chamber on the teacup.

To create a tea cup with words engraved, more advanced materials are needed, special machine tools are needed, and special designers are needed to support a large number of people. 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 just eat big fish and meat every day. A large amount of GDP is reflected in these luxury taxes. A paper clip of an international top luxury brand costs dozens of dollars. In the final analysis, it means that there is too much money, and it is impossible not to make such a struggle.

At the beginning of China's opening up, it mainly took over labor-intensive industries transferred from abroad and produced some low-end consumer goods, so the requirements for molds were relatively low. As the production of low-end consumer goods was completely covered by Chinese companies, self-competition became increasingly fierce and profits became thinner. Some enterprises that completed the original accumulation of capital began to enter the mid-to-high-end consumer goods market. The grade and quality of Chinese manufacturing were constantly improving, and what followed was the huge demand for high-end molds.

Ye Yongfa’s Xinta Mold Company made low-end molds in the early years, and it was very appropriate to describe them as stupid, big, black and thick. In recent years, Xinta Company has begun to turn to high-end mold manufacturing, and the biggest obstacle encountered is the mismatch of machine tools.

To manufacture high-end molds, high-end machine tools are needed. The high-end machine tool market is basically monopolized by foreign machine tool giants. The machine tools produced by others have good performance and high processing accuracy, but the prices are also ridiculously high. Ye Yongfa calculated that if he uses imported machine tools to produce molds completely, he will not be able to leave a penny of profit on the mold, and he will give it to foreign machine tool manufacturers in vain.

Because of this, Ye Yongfa found Han Weichang and hoped that domestic machine tool companies could provide him with machine tools suitable for fine processing and low-priced prices. In addition to Xinta Company, many similar mold companies in several provinces with developed coastal processing industries such as Jingnan and Mingxi also had the same demand. According to rough estimates, this market can provide at least 500 million yuan in demand a year, and this number is growing rapidly.

The market is very attractive, but it also requires excellent products to win this market. Tang Zifeng handed over the information brought back by Han Weichang to Canglong Research Institute. A group of engineers worked hard to exert their spirit of building a dojo in a screw shell, and tried hard to find a way to crack it in the "impossible triangle" of performance, quality and cost.

So far, Canglong Research Institute has achieved certain results. Engineers have made many improvements to the original CNC milling machine of Teng Machine, which has barely reached the level of cost-effectiveness higher than imported machine tools. However, the concept of cost-effectiveness is actually unconvincing. For people like Ye Yongfa, it is not unacceptable to spend 10,000 or 20,000 yuan more for better performance. If the milling machine performance of Teng Machine is much worse than that of imported milling machines, it is only because of the cheaper price, it is difficult to impress these people.

It is precisely because Xiao Wenjun knows this that he has never been satisfied with the original design idea. She feels that there should be another idea that can perfectly avoid current obstacles and achieve revolutionary breakthroughs.

Replacing milling with engraving is the new idea that Xiao Wenjun found. To completely remove the large-scale milling function of the original machining center and focus on fine engraving can greatly simplify the structure of the machine tool. Moreover, since the machine tool only does one job, the quality of this job can be greatly improved, which is much better than integrating various functions into the same machine tool.

As for whether separating milling and engraving will lead to waste of labor, who cares? What China does not lack the least is labor.

After understanding this, Xiao Wenjun had no intention of looking at any furniture. She urged Tang Zifeng to drive home, then plunged her head in front of the computer and started drawing pictures. The wood carving machine tool was designed by her. Now she has to switch from carving wood to carving metal, which is nothing more than increasing the rigidity of the machine tool, increasing the power of the spindle and servo motor, etc. For Xiao Wenjun, she is really familiar with it.

Of course, there are many things that need to be considered. For example, carving work requires improving the flexibility of moving parts such as workbenches and skateboards, which requires that the weight and volume of these parts should not be too large, and this will inevitably affect its rigidity. How to weigh the trade-offs between flexibility and rigidity reflect the level of a top student.

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

While drawing pictures, Xiao Wenjun took a break and chatted with Tang Zifeng. The problem of design ideas was solved, and the rest of the matter was not a problem for Xiao Wenjun, so she could still use both things.

Of course, she was mainly worried that she would focus on design and would neglect Tang Zifeng, which would cause trauma to her boyfriend's fragile heart. This was also the roommate's warning to her that as a female doctor, if she didn't pay attention to this problem, the consequences would be very serious. Since she learned about this theory, Xiao Wenjun has been reminding herself to chat with Tang Zifeng frequently, and she should not focus on her drawings like in the past.

"Just call it Diao Bed." Tang Zifeng fought fiercely with enemies from four different civilizations in front of another computer, and replied without looking back.

In fact, female doctors are thinking too much. The best way to stabilize their boyfriend is to give him a computer that can play games and keep silent while he plays games. For a man who is playing games, there is nothing more devastating than a girlfriend's talkative tutor.

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

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

"I think this name makes people mistakenly think that this is a kind of milling machine, and the carving word is easily overlooked."

"That's called CNC engraving and milling integrated composite multifunctional, cost-effective, quality and reliable implementation of three-pack mold processing precision machine tools."

"If you have the ability, please repeat it and see if you will talk about it."

"If you say it a few more times, you won't be able to string it. The longer the name looks cool, such as Bodo...uh, Bodo fifty-six."

"What is this person doing?"

"A Japanese Navy General."

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

"This name is good. Wife, you are really a master of naming. From now on, our baby's name will be yours."
