The big era starts in 1983

Chapter 47 The Biggest Secret of the Nine Branch Factory
In the nine workshops.

A not-so-big machine, it only covers an area of ​​six square meters, which is miniature in terms of a machining center.

Just for this machine, there are forty desks, eight drawing desks, four metal workbenches, sixteen single sofas, eight long sofas, and fifty camp beds.

Li Sanpao stood in the middle with his hands folded on his chest.

Then came Feng Yuchun, professor of electromechanics at Jingzhao Jiaotong University, Lin Heming, professor of electro-optics at Xijun University, Qiao Lizhi, professor of computer science at Jingzhao Jiaotong University, and Wu Qianye, professor of mechanical theory at the University of Technology.There is another one, He Qiufeng from Jingzhao Jiaotong University, a professor of materials science. He is not here tonight because he is going to the school laboratory to verify several sets of data.

A circle further outside, Zhang Jianguo's apprentice Wang Xiaoxiong, Zhang Jianguo's third junior brother Meng Hao, Feng Yuchun's doctoral student...

Three circles inside and three circles outside, this place is already full of people.

In front of the workbench, Li Dong, Li Sanpao's second apprentice, is 40 years old this year, older than Zhang Jianguo, but he studied with Li Sanpao two years later than Zhang Jianguo.

The eighth-level turner, the senior technician of the factory, is also the treasure of the factory.

Zhao Fang kept running with a notebook in his hand, he is now Li Dong's apprentice.

After completing all the tests and equipment inspection, Li Dong was already sweating profusely.

"Master, I'm fine here."

Li Sanpao turned around: "Professor Wu, Professor Qiao."

"En." Wu Qianye waved his hand lightly: "All groups start recording, the seventh test run."

The doctoral students sitting at their desks began to get nervous. There were TVs in front of them, and these TVs acted as monitors, transmitting various data to the TV screens.Because there is only one computer, which can be said to be the top household level in the world, and the unit price is nearly several thousand dollars.

The machine moved.

The task this time was to carve a relief of a horse on a square aluminum ingot at one time.

All the processing procedures were carefully considered by Li Sanpao, and Professor Qiao's students typed out letter by letter.Right now, this machining center is different from Bai Hao's original design. It was Professor Lin who led the students to improve on Bai Hao's design drawing without sleep.

Right now, all feed data is in four digits after the decimal point, that is, degrees in thousandths of a millimeter.

This is the grating ruler produced by the one-armed Lin Heming and his students.

too difficult.

The entire workshop of the No. [-] Branch Factory is full of panda eyes. Even if you are asked to sleep, no one can lie on the bed with peace of mind. This is why Bai Hao has not seen anyone for a few days, and his clothes are no longer bright. He started to wrap himself in a cotton coat active.

If I'm really sleepy, I just lean on the sofa and sleep for a while, and then join work when I wake up.

Lu Dacai, who followed Bai Hao in, just stared at it for a minute, then suddenly took a few steps forward, knelt down on the ground, and tears gushed out like spring water.

Four-axis, this is a four-axis machining center.

The equipment that Xia Guo wants to have, but doesn't have at all.Lu Dacai visited Wa Island, Beautiful Country, and Bunker Country, but these countries have formed an alliance, and they will never sell this kind of high-end equipment to Xia Country. .

This four-axis, Bai Hao knew it was done.

It's just that Li Sanpao and the four professors want more data and more research materials. They want to thoroughly research this technology and turn the four-axis into a mass-produced machining center.

Seeing that the embossed horse has been completed, when Li Dong stepped forward to measure the error value, Bai Hao walked up to Li Sanpao: "Master Li, there is such a thing. You always listen to me, I suspect that the little one has tricked us. "

"Uncle Cai, let's talk."

As soon as Lu Dacai touched his face, he ran over in a few steps: "Can I take a closer look?"

"Let's talk about more important things. You helped the factory inspect the equipment of the little devil. I personally suspect that it is an assembly problem. You have seen it with your own eyes, so tell me."

Li Sanpao turned around and looked at Lu Dacai seriously.

Lu Dacai adjusted his mood: "I didn't disassemble it, but just observed the machine at a close distance. I can't say for sure. I just said one of the problems I found. There are several places where the early installation may have damaged the bearing insulation. Technically speaking , if the insulation is damaged, then the very thin bearing oil film will be broken down by the shaft voltage, and the result after the breakdown of the oil film is, a lot, you understand."

Lu Dacai is not good at words, but what he said was the key points.

There are real experts here.

After Wu Qianye's analysis: "Yes, the breakdown of the oil film not only makes the lubrication conditions of the rolling elements poor, but also the electric sparks that may be generated will cause electric corrosion on the rolling elements of the bearing, causing the surface of the rolling elements to not only smooth but also accelerate the wear of the bearing."

Lu Dacai continued: "Because we didn't come to Qinzhou to take care of this, and there were no instructions from above, so I can't check other damaged parts. It will cost millions of dollars.”

Suddenly Lu Dacai turned his head and looked at the four-axis machining center. Just because he is not good at words does not mean he is stupid.

In an instant, he understood why Bai Hao brought him into the workshop.

"With this, we can produce the circular curve reducer by ourselves. And we can make hundreds of them in a day. This machine can, definitely can."

"Of course." Wu Qianye is very aware of the capabilities of this machine, and also knows that the things to be processed are impossible for ordinary machine tools, but the four-axis can be easily completed. It requires a program, and it can actually process hundreds of them a day.Then there is the issue of materials, and with He Qiufeng around, I can handle it.

Bai Hao put his hand on Lu Dacai's shoulder: "I said, Comrade Dacai, tomorrow you will definitely have the opportunity to enter the locked workshop, and you can steal two bearings with reducer function. No problem."

"this."

Seeing that Lu Da hesitated, Bai Hao said again: "Steal it out, I'll find someone to help, you just need to get it to the workshop door."

Lu Da didn't understand: "Why didn't you explain it directly to the factory, I think the factory will support you."

Bai Hao shook his head: "I have to make sure if it can be done first, and if I can, I won't show up. How did they force Master Li to retire back then, and how are they going to invite Master Li back today? There is no way, but if you can’t breathe, people will be suffocated.”

"Yes, yes." Lu Da only agreed.

Bai Hao straightened his body: "Zhao Fang, it's time to hire people. The workshop where the imported equipment is placed is less than 100 meters away from where Li Qiang works, okay?"

"Well, I'll go find him." Zhao Fang understood that this was an opportunity.

Although Li Qiang is slick, he never loses the chain at critical moments. If Li Qiang is cowardly this time, he would be ashamed to ask Bai Hao to reserve a regular job for Li Qiang. Of course, this matter cannot be forgotten about Lu Qiao.
