The precision eyes, the slightest function ... use the ingenuity to measure the "Chinese precision"

According to the road of science on September 17, the People's Daily Online, we only believe in and seek the future.

They have worked hard and seek excellence, so that the great powers can stand on the top of the world; they break through innovation, carefully crafted, and make Chinese manufacturing label "smart manufacturing"; they have the courage to challenge, carefully ingenious ideas, and let the infrastructure of the great power continue to write miracles.

Over the past ten years, China has ranked the world's first manufacturing country's position, and the major power, precision craftsmanship, and heavy infrastructure have created the strength of China in the new era. From "Made in China" to "Chinese Creation", from "China Speed" to "Chinese Quality", from "Chinese products" to "Chinese brands", more and more Chinese brands are world -renowned and have become shiny national business cards.

Behind the innovation and creation is the continued struggle of generations of artisans and central enterprises. They use ingenuity to measure the "Chinese accuracy" to allow Chinese manufacturing to enter the earth, shuttle time and space, and quench a higher quality, higher level Extreme China.

"Embroidery Kung Fu" in the great power of the great power

The dangerous building is 100 feet high, and the stars can be picked. For thousands of years, in the face of the vast starry sky, there is a romance that belongs to China.

On July 25, 2022, the Qi Tian experimental cabin was successfully connected to the front port of the sky and the core cabin. The microwave radar continued to output high precision, and the accuracy of the angle measurement of 100 kilometers was 0.1 degrees, which perfectly helped accurately meet.

Looking up at the starry sky and down -to -earth, the Chinese people step by step, constantly exploring the mystery of the universe, Tiangong, Chang'e, Tianwen ... the Chinese flying dreams are becoming a reality step by step. On the journey of "Flying", high -precision space -to -connection and docking technology is a key ring, and microwave radar is the space "matchmaker" for the "crossed -piercing lead" to meet. It allows the two spacecraft to find each other in the vast space and continuously output high -precision measurement data. The traction spacecraft from "meet" to "connect" until it is successfully "holding hands".

Sun Wu, general designer of 25 microwave radar in China Aerospace Science and Technology Second Hospital, likes to compare the microwave radar to the "thousands of miles" to explore the world of space. It is with the precise assistance of these "eyes". At 36 points, "Shenzhou 8" and "Tiangong -1" completed the world -renowned romantic "space kiss". China has become the third country in the world to master the docking technology.

Sun Wu said, "In the past 10 years, we have participated in major aerospace projects such as space station construction, lunar exploration projects, and Mars detection, and achieved three firsts and ten games."

From a paper scheme to the success of the task, it is a lot of practice, it is carefully crafted, and countless aerospace researchers have been created by innovation and creation, strict and cautious, and adhere to the quality of "zero defects" and "one success" to make the carrying carry The big power of the flying dream soars space.

"Water conservancy is not arguing." From ancient times to the present, facing thousands of rivers, the Chinese thinking and practice have never stopped. From Dayu to water, Dujiangyan, and Greater Canal to the Three Gorges Dam, China continues to treat water and water to allow water conservancy projects to benefit the people.

Baihetan Hydropower Station

On the Jinsha River, the white crane bright wings, interpreting a "balanced dance".

On June 28, 2021, the first group of the Baihetan Hydropower Station was officially put into production and power generation. As a global single -machine capacity of the maximum capacity of one million kilowatt water rotations, it achieved a major breakthrough in my country's high -end equipment manufacturing. A millions of kilowatt -kilowatt -hydraulic units weigh more than 8,000 tons and more than 50 meters high, but in the process of building this behemoth, there are many details, and the accuracy is calculated in millimeters.

Among them, the rotor magnetism is the core component of the Millions of Power Power Unit of the Baihetan Hydropower Station, which is stacked by more than 16,000 magnetic pins, nearly 4 meters in height, more than 15 meters in diameter, and weighing more than 1,200 tons, like a large large number The "Thousand Layers of Cake", the stacking process depends on "Embroidery Kung Fu". One by one, one layer, every link needs to be excellent. The magnetic cricket center deviation required by the Baihetan Unit is 0.15 mm. The relative theoretical deviation of the Magnetic Centers made by Oriental Electric does not exceed 0.02 mm, which is equivalent to one -third of the diameter of a hair.

On August 18, 2020, Dongfang Electric's first million -kilowatt -hydraulic unit rotor independently developed in the world was successfully lifted at the Baihetan Hydropower Station.

The "embroidery kung fu" on the behemoth relies on the excellent ability, and the support behind it comes from the spirit of scientists and the "craftsmanship". The rotor is hailed as the "heart" of the water wheel generator set, and the fine mill is a key ring of rotor manufacturing. Its accuracy depends on the experience of workers and "feel", which has high requirements on the operator. The 15 -handed spatter craftsmen were stationed at the Baihetan scene for a long time to polish the boutique "heart" of the Baihetan unit.

Oriental Electric has a 25 -year -old shovel scheduling scheduling Chen Changsong and said, "The Baihetan project may be the last major project that our generation of shovel has caught up. Our pride is born. "

"Fangcun" quenching in China

If you want to be good, you must first benefit your instrument.

The manufacturing industry determines the comprehensive strength and international competitiveness of a country, and the fineness of the tools reflects the level of the basic process of a country's manufacturing industry.

Without precision measurement, there are no precision products. As the core functional component of the precision displacement measurement device, it is necessary to rely on the edge, and it must be self -reliant. Chinese scientists have a different approach, and the way of thinking based on "time and space conversion" proposes the important academic idea of ​​"time measurement space", and from this, the original time grid technology was born. High -precision measurement purpose. Nano -cricket

Ten years of grinding a sword, grinding a foot for twenty years, and practicing a pair of "precise eyes". From the concept of "Shilu angle sensor" from Chongqing in 1996, the Shizha team adheres to the independent research and development path. "Nano -time grid"), continuously overcome product reliability, diversified application scenarios, market recognition, and many other "block tigers". Take a self -controlled road under technical blockade.

"Go out of the laboratory and realize industrialization." In April 2021, General Technology Group and Chongqing University of Science and Technology jointly established the GM's National Testing Shizha Technology Co., Ltd., marking a new stage of the official opening of the transformation application and serving the market users. At present, nano -time grid technology has been widely used in the fields of CNC machine tools, chip manufacturing, metering testing and other fields. It is gradually filling the gap in the field of high -end precision displacement measurement in China, becoming a strong backing in the development path of domestic high -end equipment enterprises.

One person's hair diameter is about 0.08mm, while the diameter of a micro -precision knife with a finely entered mandarin can reach 0.01mm. This kind of high -trail milling cutter has been produced by the leading enterprise of the micro -precision knife industry in my country, and it is relying on innovation and ingenuity behind this.

China ’s Minmetals Enterprises have successfully developed a diameter of 0.01 mm milling cutter. Using this extremely diameter milling cutter, 56 Chinese characters can be made on a grain of rice.

Li Xueguang, the person in charge of the 0.01mm minor -milling cutter development project of the China Minmetals Tungsten Gaoxinzhou Company Technology Center, said that in early 2021, a company produced by the large -scale produced by the country, and the Jinzhou Company urgently asked 0.01 to 0.04mm microtamin. At that time, the team did not have this ability, but could only look in the eyes and was anxious. "We have accelerated the rhythm of R & D, and have gone through dozens of plans, countless experiments, and successively broke through the bottlenecks such as small breaks, difficult to grind structure, and accuracy. A 0.01mm extremely small diameter milling cutter, with the previously developed 0.01mm extremely diameter drill, forms the "double sword combination" trend. "

"The contribution" is ingenious. This kind of extremely trail milling cutter is only one -eighth of the hair, and it is almost invisible to the naked eye. It is very good in electronic information, automobile manufacturing, optical instruments, biological engineering, aerospace and other fields. The minor diameter single -edged milling cutter seems to be unusual, but there is a Qiangkun inside, and the shape is complicated. It needs to grind 6 parts such as the rear angles, side gaps, and spiral grooves on the hard alloy cylinder with a diameter of 0.01mm. The structural design and processing difficulty is self -evident.

A micro -milling cutter releases big potential; a small drill head has a large industry. Today, the domestic extremely path mills and drill bits are checked and cut into mold steel, stainless steel, copper, aluminum, and resin soft materials with a slender body. Great to strong, from manufacturing to creation.

See the vast detail. From scratch, from small to large, every step of footprints is writing and witnessing great leaps again and again. Numerous Chinese scientific researchers and Chinese companies have studied and pondered between square inches, and have been tempered the gold content made by China.

Big country infrastructure staged "Qiankun movement"

Xiamen Houxi Coach Station flat rotation

Thousands of miles a day, and the sky turns through. Behind the infrastructure miracle that shocked the world, there were a group of people who believed in miracles and created miracles.

In September 2019, in order to make a construction plot to the Fuxia high -speed rail, Xiamen Houxi Coach Station staged a "most cattle move". The main station building of the bus station is 162 meters long, 33.6 meters wide, weighs 30,000 tons, and the translation distance is 288.24 meters, creating the world's largest translation area, the heaviest load, and the longest -distance single building curved rotation and translation world record. Refresh the Guinness World Records.

This time, the Rotary Rotor Rapida reaches 90 degrees, and the movement position is up to 288 meters. It is the first time in the industry. For the first time, the project adopts the technology of "alternating step -by -step push and translation" to give the station's 129 flat -shift stress points. Simulation simulation with the structural model in the computer, digital simulation deduction and calculation of the stress, direction, high range, and accurate displacement adjustment mechanism of the runner, saving 18.71 tons of metal materials.

"The accuracy of translation" is amazing, how is this achieved? "Its principle is to install step strokes and uneven settlements such as track stagnation and uneven settlement at the bottom of the building at the bottom of the building. Like the 'feet', let the building go to the new site along the orbit. "Chen Fanhong, an engineer of China Construction Group, said that through the accurate control of each" shoes "and automatic adjustment of different positions and displacement during the rotation of rotation, The amount controls the error within 2 mm to ensure that the bus station is always within the range of elastic changes, so that it can "run fast" and "not wrestling", and finally complete the rotation and translation 2 days in advance. This time, "Qiankun moved", while saving construction investment, it also avoided a large number of construction waste, dust and noise pollution such as demolition and reconstruction, and added a vivid footnote to the country's conservation of society. From the transplantation of a tree seedlings to letting buildings walk on the earth, China Construction has led the industry's reform and development with scientific and technological innovation, depicting the tide of the times, the trend of development, and the wave of dreams. Chinese builders poured the new image of China with the most reliable hands, and outline the new appearance of the earth with the most calm brushes.

World Record, China Creation; Chinese Enterprise, Metropolitan Enterprise Wisdom. Manufacturing is the mainstay of the real economy. It is not only the foundation of a strong country, but also a stage for creating a miracle. To stand up the backbone of the manufacturing industry, the central enterprise as the "national team" is heavy. The three -year operation of the state -owned enterprise reform is imminent. A group of central enterprises are accelerating the stronger and bigger, and the new bureaus will be opened in the change bureau and moved towards the goal of building a world -class enterprise.

The statue of the struggle made by Chinese manufacturing will set a strong attitude of my country's economic and social development in the new era, and promote the transformation of our country from a large manufacturing country to a manufacturing power. To the extreme of details and use the spirit of scientists and craftsmanship to the extreme. They use Chinese precision to refine the more dynamic, creative and competitive "Made in China".
