When will I have a long tassel?

In fact, Xiao Wenjun is a typical "black under the lamp". She designed the wood carving machine tool of Linyi Machinery, and this design brought her several million in patent fees, allowing her to save money from working hard to give lectures. A poor college student who used money to buy a laptop suddenly became one of the most invisible rich women on the Tsinghua campus. According to her own guess, she is probably the richest among Tsinghua students, unless there are other low-key wealthy people like her.

When she was thinking about new ideas for the mold milling machine a few days ago, she vaguely felt that she had an idea in her mind, but she could never catch it. She was limited by the routines of traditional machining centers and always wanted to innovate based on this concept. As for any idea she could think of, designers from large foreign companies had already thought of it and had registered patents, leaving her scratching her head and unable to start.

Just standing in the furniture showroom, touching the pattern on the wardrobe door, she suddenly realized that her thinking these days was completely wrong. Mold manufacturing is actually carving patterns on metal surfaces. Just apply the idea of ​​​​wood carving machine tools directly. Why should you limit yourself to the design routine of a machining center?

In principle, the wood carving machine tool is also a milling machine. When she first designed the Changying wood carving machine tool, she referred to the design of the copy milling machine. However, as Changying wood carving machine tools have been improved one after another, the differences between them and traditional milling machines have gradually emerged, that is, they focus on fine processing using small cutter heads, which strengthens the concept of "carving".

Of course, traditional machining centers can also use small cutter heads for fine processing, but their main function is milling on a larger scale. In mold processing, if the size of the mold is large and the details are not high, it is more appropriate to use a machining center, whose processing efficiency is higher. However, in recent years, consumer products have become more and more refined, and the requirements for mold refinement have become higher and higher. Traditional processing methods are somewhat unsuitable.

For example, in the past, a cup made of resin was smooth from top to bottom, and the design and processing of the mold 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 engraved on them later. They can only be carved during mold manufacturing and injection molded in one go during production.

To make such molds with patterns or words involves fine processing. Using traditional machining centers to perform this kind of fine processing can be said to be like anti-aircraft cannons beating mosquitoes. It’s not that they can’t be shot down. The key is that the efficiency is too low, and a lot of capabilities are completely wasted.

Xiao Wenjun’s original design idea was to improve the fine processing capabilities of the machining center. This means that the same machining center must be able to perform milling operations of large opening and closing, and must also meet the fine processing requirements of carvings on hair. The results will be natural. It increases the difficulty of machine tool design, greatly increases the production cost of machine tools, and ultimately loses the price advantage.

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

The upgrading of consumer goods is a process of collecting luxury tax. For example, a teacup is for drinking water. As long as it can hold water, it is a qualified teacup. If manufacturers are satisfied with making a container for water, then they cannot make money. If they want to make a lot of money, they must do various things on the teacup, such as changing the artistic shape, engraving a Dream of Red Mansions on the teacup, etc. of.

To make an engraved teacup requires more advanced materials, special machine tools, and specialized designers who can feed a large number of people, but the final product is still just a cup filled with water. In fact, it does not bring any new benefits to consumers.

The per capita GDP of Western countries was once dozens of times that of China. This does not mean that Western people eat big fish and meat every day. A large amount of GDP is reflected in these luxury taxes. A paper clip from one of the top international luxury brands costs tens of dollars. In the end, it’s just too much money to spend.

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 is completely dominated by Chinese companies, self-competition becomes increasingly fierce and profits become thinner. Some companies that have completed primitive accumulation of capital have begun to enter the mid-to-high-end consumer goods market. The grade and quality of Chinese manufacturing are constantly improving. , followed by a huge demand for high-end molds.

Ye Yongfa's Xinta Mold Company made low-end molds in the early years. It is very appropriate to describe it as "silly, big, black and thick". In recent years, Xinta Company has begun to shift to high-end mold manufacturing, but 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 they produce have good performance and high processing accuracy, but the prices are also ridiculously high. Ye Yongfa calculated that if he entirely used imported machine tools to produce molds, he would not have a cent left over from the molds, and all of them would be given to foreign machine tool manufacturers.

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

The market is very attractive, but you also need 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 and used the spirit of a dojo in a screw shell to find a solution to the "impossible triangle" of performance, quality and cost.

So far, Canglong Research Institute has achieved certain results. Engineers have made many improvements to Tengji's original CNC milling machine, and it has barely achieved a price-performance ratio higher than that of imported machine tools. But the concept of cost-effectiveness is actually unconvincing. For people like Ye Yongfa, spending an extra ten or twenty thousand yuan for better performance is not unacceptable. If the performance of Tengji's milling machine is worse than that of imported milling machines, There are too many, and it is difficult to impress these people just because the price is cheap.

It is precisely because Xiao Wenjun knew this that he was never satisfied with the original design idea. She felt that there should be another way of thinking that could perfectly avoid the current obstacles and achieve a revolutionary breakthrough.

Replacing milling with engraving is the new idea Xiao Wenjun found. Completely removing the large-scale milling function of the original machining center and focusing on fine engraving can greatly simplify the structure of the machine tool. And because 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 a waste of labor, who cares? What China does not lack most is labor.

After understanding this, Xiao Wenjun still had the time to look at any furniture. She urged Tang Zifeng to drive home, then plunged into front of the computer and started drawing. She designed the wood carving machine tool. Now she has to switch from wood carving to metal carving, 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, it is really a familiar road.

Of course, there are many things that need to be considered. For example, engraving operations require improving the flexibility of moving parts such as worktables and skateboards. This requires that the weight and volume of these parts should not be too large, which will inevitably affect their rigidity. How to balance flexibility and rigidity reflects the level of an academic master.

"Zifeng, this kind of machine tool needs to be distinguished from traditional CNC milling machines. What do you think it should be called?"

While Xiao Wenjun was drawing pictures, he took some time to chat with Tang Zifeng. The problem of design ideas was solved, and the remaining things were no longer a problem for Xiao Wenjun, so she could still do two things at once.

Of course, she was mainly worried that by focusing on design, she would neglect Tang Zifeng and inflict trauma on her boyfriend's fragile mind. This is also the warning given to her by her roommates. As a female doctor, if she does not pay attention to this issue, the consequences will be serious. Ever since he learned about this theory, Xiao Wenjun kept reminding himself to chat with Tang Zifeng often, and he could no longer be distracted as soon as he started drawing like in the past.

"Let's call it Diao Bed." Tang Zifeng was fighting fierce battles with enemies from four different civilizations in front of another computer without looking back.

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

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

"Then it's called an engraving and milling machine."

"I think the name will make people mistakenly think that this is a milling machine, and the engraved characters will be easily overlooked."

"That's called CNC engraving and milling integrated multi-functional, cost-effective, quality, reliable and special precision machine tool for mold processing with three guarantees."

"If you can, say it again and see if it makes sense."

"If you say it a few times, it won't get confused. A longer name will make it look cooler, such as Bodo... uh, Bodo fifty-six."

"What does this person do?"

"A Japanese admiral."

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

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

"Tang Zifeng, you really embarrass liberal arts students!"
