Technology: breaking the hegemony that monopolizes the world

In high-precision processing production, the cooperation between the slicing system and the blade is necessary.

In addition to size, there are three key parameters that determine blade characteristics: diamond (abrasive) size, diamond content and type of bond. The bond is a matrix of various metals or diamond abrasives distributed therein.

The combined effect of these elements determines the life and cutting quality of the insert.

Changing any of these parameters will directly affect blade characteristics and performance. Selecting the best blade for a given slicing process may require a balance between blade life and cut quality.

Other factors, such as feed rate and spindle speed, may also affect insert selection. Cutting parameters have a direct relationship to material removal rate, which in turn affects blade performance and process efficiency.

For a process in order to optimize the blade, designing a sufficiently efficient test method can reduce the number of tests required, and provide the combined effect of the blade characteristics and process parameters, and these require correspondingly intelligent program assistance.

And such exquisite "knife skills" are naturally extremely versatile.

Killing and stealing goods is too common, and the old yellow knife method is too one-sided, and cutting wafers is where it can play its best.

Gu Qing naturally knows the importance of cutting wafers.

The first step in chip manufacturing is to make wafers, and then use a wafer slicer to cut silicon ingots into wafers of the required thickness.

A good knife method can cut better and larger thin silicon wafers, and chips are the products of thin silicon wafers.

Of course, this chip can be the chip of what we usually call a mobile phone computer, or it can be a storage chip of a memory stick or a memory card. The difference is that the design of the chip is different.

However, Gu Qing did not hide his clumsiness when it comes to sword skills, because his foundation is really bad, and the knowledge passed down by the Dimensional Empire does not use silicon chips...

"It's okay to cut ordinary materials. If you always want to get silicon wafers, we still can't meet that requirement, and as far as the current micron precision processing is concerned, it is still a laboratory product, which cannot be mass-produced, and the yield rate cannot be guaranteed. .”

A basin of cold water was poured on Professor Zhuang's head, which made him calm down suddenly.

After a while, the old man murmured to himself: "That's right, how old are you? Without equipment or talent, how could you have this kind of technology."

But when he looked at the mechanical arm in the workshop, he slapped his head again.

"Then how is your robot technology doing now?"

A fellow professor couldn't see it anymore, and dragged Zhuang Youwei back to the team.

"Old Zhuang, don't get carried away by Ziguang's affairs. They bought the technology from Germany's Qimonda, which is not bad."

"Old Cui, I'm a little dizzy. It's not like you don't know that the monopoly of the United States, Japan and South Korea in semiconductors has restricted our high-end technology in Daxia everywhere..."

The professor called Old Cui patted Zhuang Youwei on the shoulder and comforted him: "Others are also working hard to overcome it. We must first complete a few projects of our own before we can support them."

Zhuang Youwei who calmed down nodded.

The visit of the research team in the afternoon also returned to normal.

The mandarin duck hot pot in the evening was a home away from home, and perhaps it was an expectation for the younger generations. Zhuang Youwei also expressed that he would help Gu Qing and Harbin Engineering Group to match each other and help each other to make the robot project bigger and stronger.

Gu Qing was flattered.

During his previous investigation, he also learned how hard the "body" of Harbin Institute of Technology is.

Since its establishment more than ten years ago, Harbin Institute of Technology has achieved extraordinary operation and leapfrog development by taking advantage of the talents and technological advantages of Harbin Institute of Technology and its own successful capital operation. It is a comprehensive large-scale enterprise group with strong strength and strong international competitiveness based on the financial sector as the core and the commercial service industry sector as the guarantee.

Moreover, Harbin Engineering Group, as a holding group company, holds ten large group companies with capital as a link, holds Heijiang Dairy Group Corporation, participates in the listed company "Aerospace Science and Technology", and establishes "Gongda Hi-Tech" and "Aerospace Property" by way of initiation. Two standardized joint-stock companies initiated the establishment of the first venture capital company in Heijiang and the first joint-stock venture capital company in the country.

These ten large-scale group companies have nearly a hundred wholly-owned, holding, and shareholding companies involved in exhibition sports, bio-food engineering, dairy products, tourism hotels, information science and education, property management, and logistics management. After years of accumulation, it has fully matured, and it is at the leading level in the industry in terms of talent reserve, technical force, product structure, etc., and has all the elements for rapid growth.

Of course, what Gu Qing values ​​most is the eight regional overseas branches established by Harbin Engineering Group in the United States, Singapore, Neon, Russia and other countries, as well as the two listed companies it controls, and the import and export management rights granted by the state.

Cooperating with such a behemoth, if it is not swallowed up, it will definitely be full of fat.

As for cooperation, only when both parties have what they need can be regarded as cooperation.

What Zhuang Youwei wants, Gu Qing knows, but what should be given in exchange for the other party's things in cooperation is the key point.

After wandering around the research room on the top floor, his eyes finally fell on something like a honeycomb.

"Boy, is this the special material you mentioned last night?"

In an idle laboratory in the laboratory building, Zhuang Youwei looked at the "beehive" on the test bench, but he was not surprised.

After all, I have been in this industry for a long time, and I can see all kinds of exotic materials.

Gu Qing nodded, picked up the "Honeycomb" and placed it in front of the research team.

One side introduced: "Pneumatic honeycomb network, this is a natural rigid-flexible structure, which has the characteristics of large deformation, high flexibility, high load-to-weight ratio and low cost.

Parts constructed using it can resemble mollusks that are both supple and flexible.

The inherent compliance and continuous deformation characteristics of soft robotic arms are in tune with it. "

Gu Qing took out another honeycomb-shaped part, kneaded and pulled it, and explained: "The deformation of the honeycomb aerodynamic network structure is caused by the folding and stretching of the hexagons that make up the honeycomb. It is also flexible. Preparation Simple and durable.

And the honeycomb aerodynamic network structure is a combination of honeycomb and airbag. When the airbag is inflated, it depends on the structural deformation of the honeycomb to produce bending or elongating motions in different directions. "

After putting down the beehive that had been stretched and deformed in his hand and recovered, he picked up the "rough mechanical arm" that was improvised just two days ago.

"This is the first time I have made an arm independently. Of course, it is a familiar rigid robotic arm. There is a set of motors, reducers, and controllers on each joint. But the weight and cost are high, and the effect is not great. Just this arm cost tens of thousands of yuan, and I hadn’t started a business at the time, so I was forced to eat steamed buns every day.”

PS: Thank you for the recommendation tickets from Little Fury War, Chenmeng Zuiyin, Yang Sanshui, Yinhe Gaofushuai, good night everyone.
