This chapter is a madman hand-hitting)

The reason why he finally chose the Swiss Royal Optical Instruments and Equipment Company to cooperate in the development of tunnel microscopes and penetrating electron microscopes in Switzerland was that Yang Weiping took a fancy to the company's advantages in the research and development and manufacturing of optical measuring instruments.

Dual-frequency laser interferometer is one of the indispensable core components of the ultra-dense machine tool for position measurement in the processing process.

However, even if he now gets the dual-frequency laser interferometer from Switzerland, with the existing equipment and technical strength of the first machine tool factory in Beijing, it is obviously impossible to manufacture a super-dense machine tool, but it is still promising to develop a general-purpose Jingmi lathe, boring machine, milling machine, grinding machine, and drilling machine.

After a day of observation, communication, and listening to their discussion and debate next to this technical innovation group for about half an hour, Yang Weiping basically figured out that their improvement ideas for the lifting platform heavy-duty gantry CNC milling machine are still stuck in the design ideas and concepts of CNC machine tools in the early sixties, and most of them are based on Soviet technology.

Hearing that the technical innovation team said that it was reasonable in the design of the bed structure of the new machine tool, and that the mother-in-law said that the mother-in-law was reasonable, Yang Weiping finally spoke.

"Ahem!" Yang Weiping cleared his throat and interjected with a smile: "Masters, I want to say a few words after hearing you say so much. The cutting amount of Jingmi machine tool is generally not large, and the working load is generally small, and its static strength and stiffness can generally meet the design requirements.

Therefore, the dynamic energy of the machine tool has become the main factor affecting the working energy of the machine tool and the quality of the machine tool product. The machine bed is an important basic component of the machine tool. The dynamic energy of the bed directly affects the quality of the parts to be machined.

In order to ensure that the large-scale Jingmi machine tool has good dynamic characteristics, it is necessary to ensure that the bed has good dynamic energy. Before optimizing the structural parameters of the large-scale Jingmi bed, it is necessary to determine the bed structure with good dynamic Xing energy.

The form and arrangement of the ribs in the bed have a great influence on the dynamic energy of the machine. In addition, the spindle centerline of the large CNC milling machine, relative to the parallelism of the horizontal worktable, is also one of the rework indicators of the machine tool.

In a large milling machine, because the spindle is fixed on the ram, the center of gravity moves when the ram moves back and forth, which causes the spindle to be in the front, and the parallelism of the spindle centerline at the rear end changes greatly. Therefore, the degree of jing is reflected in the CNC milling machine is a comprehensive index, which requires mechanical personnel to do a good job of geometric degree adjustment. In the design of the machine tool structure, it is necessary to take into account the mechanical angle compensation. ”

"yes! I didn't think of that!" said an old engineer about fifty years old with black-rimmed glasses and gray hair, and suddenly realized that he slapped his thigh and shouted excitedly.

"We can't even ignore the dynamics of the machine! It's so undeserved......"

"Oh my God, why don't you say hello when Director Shi, Secretary Zhang, and Chief Engineer Lin come!"

"Ahh Patronizing and fighting with you, I didn't even notice that Secretary Zhang and Chief Engineer Lin of the Shi Factory were here......"

"Killed by you nerds...... Director Shi is good, Secretary Zhang is good, and Chief Engineer Lin is good. I'm sorry, we didn't even notice a few leaders coming. An old worker in his fifties dressed in overalls hurriedly came over and bowed.

"It doesn't matter, to do your work, you have to be serious! You have to be dedicated! You have to pay full attention!" Shi Wenbo said solemnly: "I just saw you guys arguing about technical issues. This is a good thing! Our No. 1 Machine Tool Factory in Beijing should carry forward this kind of conscientious and responsible work attitude and work style! Only in this way can we do our work better!

Comrades, I would like to tell you the good news that Director Wu and Director Yang of the National Defense Industry Office of the State Council have come to inspect our factory and come to visit you! The person who interrupted you from the speech just now is Director Yang of the Industrial Affairs Office! Everyone applauded and welcomed Director Yang to guide our work again!

......More than a dozen people present applauded vigorously.

In particular, the old engineer who wore glasses slapped his palms the loudest and hardest.

"Hehe, since Director Shi has spoken. Then I'll say a few more words. Yang Weiping pressed his hands weakly, signaled everyone to be quiet, walked to the edge of the somewhat old gantry milling machine, reached out and touched the cold bed, and said solemnly with a solemn look:

"For the past two decades. Beijing No. 1 Machine Tool Factory has developed the first CNC milling machine for electron tube control system in China, and has made outstanding contributions to the research and manufacturing of CNC machine tools in China. This is the glory of the first machine tool factory in Beijing, and it is also the honor of the new Huaxia machine tool manufacturing industry. It will inevitably be forever recorded in the annals of China's industrial development!"

"Papapapa......" Shi Wenbo took the lead in applauding vigorously, and of course everyone applauded violently excitedly.

"But!" Yang Weiping looked around with bright eyes, and after everyone quieted down, he said solemnly: "We must see that our machine tool manufacturing, especially the design, research and development and manufacturing of Jingmi machine tools and super Jingmi machine tools, has lagged far behind the developed capitalist countries in Europe and the United States, and in this regard, even the Soviet Union has lagged behind!"

The advantages of CNC machine tools such as high degree of processing, high processing efficiency, strong adaptability, and ability to reduce the labor intensity of workers are increasingly recognized by countries in the world. Developed countries in Europe and the United States are deeply aware of the incomparable power of Jingmi CNC machine tools. Modern manufacturing industry is inseparable from Jingmi CNC machine tools, which can be said to be absolutely impossible, and there is no way to survive!

Because of this, the developed capitalist countries in the West, they have regarded Jingmi CNC machine tools and super Jingmi CNC machine tools as strategic important equipment and materials. They have formulated a notorious 'Batumi Agreement' against our socialist camp! They have listed Jingmi CNC machine tools and super-Jingmi CNC machine tools as embargoed strategic materials, and have imposed an extremely strict technical blockade on us.

They think that by implementing a technical blockade, they will be able to force us forever in terms of technology, and they will always be able to ride on our heads and be powerful, and our defense industry will never be able to surpass them.

However, they despise our country, our nation, and the wisdom and innovation of the hundreds of millions of working class and working people in New China. When New China was poor and white, we used our hands and abacus to build the atomic bomb.

Now, we have a complete industrial system, with 150,000 provincial heavy industries and 230,000 provincial light industries, can't we use the wisdom of our Chinese people to manufacture a new type of Jingmi machine tool with completely independent intellectual property rights?"

"We can!" shouted the bespectacled old engineer excitedly, "surely!"

"Yes, we can! We can!" Zhang Weimin, the secretary of the party committee, clenched his fist with his right hand and shouted with his arms raised.

"We can!

"Yes! We must be able to, we must be able to!" Yang Weiping also clenched his fist with his right hand, waved it vigorously, and continued in a loud voice: "Because, Jingmi CNC machine tools and super Jingmi CNC machine tools are the most important indicators to measure a country's comprehensive strength, and they are the pillars of modern industry.

Without the ability to process densely, we will not be able to produce the world's first-class aero engines, and our fighter planes will not be comparable to the advanced fighters of Western capitalist countries;

Without the ability to process the enemy, we would not be able to produce the world's first-class tank engine, and our tanks would not be able to defeat the enemy's most advanced main battle tanks;

Without the ability to manufacture the best marine propellers, our ships and submarines cannot win against the enemy's fleet;

Without the ability to process things closely, our defense industry will never be able to catch up with Britain and the United States, and even that evil neighbor in the east will dare to challenge our dignity again! Comrades, if you are backward, you will have to be beaten! This is not a matter of the will of any country or people!

Therefore, the research and development and manufacturing of machine tools are related to the development of the national defense industry, the dignity of our country and nation, and the great cause of the rejuvenation of our Chinese nation! Processing in one of the large-scale Jingmi group.

We should fully mobilize and give full play to the collective wisdom of the broadest masses of the people, carry forward the glorious revolutionary tradition of not fearing hardship and death, self-reliance, and hardship and simplicity, and do our best to re-emerge the Chinese nation at the top of the world's realm, and strive all our lives! Do you have any confidence?

"Yes!"

"Yes!"

"Yes!"

Wu Hanzhong took the lead, and everyone clenched their fists and raised their arms, and the crowd was excited.

"Having said so much, of course, I can't just say nothing, today, I will learn abroad about the design parameters and optimization of the machine bed structure design parameters and some of the experience, to share with you. After Yang Weiping finished speaking, he squatted down, picked up a pencil, and laid a drawing of the structure of the machine tool bed on the ground, explaining and drawing at the same time.

Seven members of the technical innovation team, including the chief engineer Lin Jianguang, all gathered around, listened attentively and attentively, and each took out their work notebooks and took notes while listening.

Soon, Yang Weiping quickly and professionally drew a structural model drawing, he pointed to the drawing with a pencil in his hand, and explained:

"This is a parametric finite element model of the original bed that I designed based on your previous structural drawings. This model is helpful for studying the influence of the thickness of each rib on its dynamic characteristics in the rectangular rib layout of the bed, and takes the thickness of the rib plate and the position of the rib plate as the design parameters to optimize the design parameters of the bed structure.

Through the calculation and analysis of the optimization results, the weak points of the bed structure can be found, and an improved design scheme is proposed according to the shortcomings of the original bed......"

O connoisseur!

What a real master!

Lin Jianguang, chief engineer of Beijing No. 1 Machine Tool Factory, for the first time, had a heartfelt admiration and admiration for this young Director Yang.
