Chapter 480 CNC machine tools (first update)

Sun Aiguo and the deputy director in charge of military industry nodded when they heard Liu Hai's words.

"Everything will go according to your plan. Helicopter manufacturing is now our top priority. I hope everyone will carry forward the spirit of hard work."

"Work hard to complete the tasks assigned by Section Chief Liu, and strive to have the prototype ready before National Day." Sun Aiguo said to several others.

Sun Aiguo said this because Liu Hai just said that the entire aircraft could be manufactured in July or August.

"Guaranteed to complete the mission!" Liu Hai can certainly ensure that the super-reduced Black Hawk helicopter is successfully completed. He already has production experience in the aircraft carrier space.

Of course, if this speed were revealed, the jaws of Western scientists and researchers would probably drop.

There are actually people who engage in scientific research and production like this. You can build a helicopter in just two years at most?

Of course, in today's China, I'm afraid only Liu Hai can do this and other people believe it.

If another person dared to say this, the leader would spit thick phlegm on him and tell him to get away as far as he could.

But Liu Hai has countless successful precedents, and the work progress of Liu Hai can also withstand the test.

Ma Fuqiang quickly clapped his hands when he heard the factory director's words.

However, Ma Fuqiang also felt a headache when thinking about the assembly process of hundreds of thousands of words.

No matter it is any aircraft engine assembly, it is a very complicated matter.

The reason why Liu Hai and Li Dali were able to complete the assembly within three days was because they did a good job in the preliminary work.

The key to the turbine and fan trimming of aeroengines is that each turbine blade or fan blade will be carefully weighed and then trimmed by experienced workers.

The task of balancing the bangs was left to Gou Rong's team.

Each turbine blade and fan blade has its fixed position.

Each fan blade and turbine blade must be weighed after processing, and then when balancing, there are many turbine blades or fan blades to choose from.

Of course, there are many assembly technical points for the overall aeroengine. This thick assembly process is completely summarized by countless workers during production and use.

To put it bluntly, in my previous life, Liu Hai was in school and used the aircraft engine assembly process manual to practice. Now it is an extremely precious thing.

Liu Hai mainly has a group of people from the maintenance department who serve as the backbone of the entire workshop.

Otherwise, Liu Hai alone would never have thought of taking out the turboshaft engine so quickly.

The people in the maintenance department have rich manufacturing experience, plus the experience of copying the Gazelle helicopter last time. Of course, the most critical thing is the design of the bangs and the ratio of materials.

Liu Hai has such an ability to cheat, and it took him nearly a year and a half to take out the turboshaft engine.

The subsequent body manufacturing is relatively simple, which means the entire power unit is slightly more complicated.

Sun Aiguo immediately reported the good news to his superior department. He was really depressed when he was asked by the leader of the superior department.

The turboshaft engine continued to be tested under Liu Hai's supervision, while Ma Fuqiang and others slowly began to assemble the second turboshaft engine while learning the assembly process.

Every step must be done carefully, and Liu Hai comes to check it out from time to time. Most of the time, Li Dali is in charge.

Ma Fuqiang and others will have to wait a little longer to get started. The main thing now is to observe and participate, and remember every step.

Ma Fuqiang and others worked even harder because after the turboshaft engine was successfully tested, the factory gave each person a bonus of ten yuan.

In addition, he was also issued a certificate of honor for first-class collective merit, something Ma Fuqiang could never dream of getting in other workshops.

Of course, Ma Fuqiang and others were also completely impressed by Liu Hai. They never expected that there would be such an incredible person in our factory.

At the same time, everyone speculated whether the big airplane in the motorcycle factory was manufactured by Liu Gong in front of them.

With just one engine, you can get first-class collective merit and get a bonus of ten yuan. So what kind of reward will you get after the helicopter is completed?

Li Dali and others are no longer surprised by this. People in the Maintenance Department have received too many honors. They have also received many bonuses and medals over the years. As for the certificates, there are just piles of them.

Liu Hai's main focus is on the design of the helicopter.

As for the new helicopter rotor designed by Liu Hai, the entire design information and technical information were handed over to a helicopter manufacturing factory in Northeast China after the superior department urgently arranged for confidential personnel to copy them.

They are required to manufacture this helicopter rotor as quickly as possible and at all costs, manpower and material resources.

Because the superior department leaders know that Comrade Liu Hai can do things very quickly. He said that it can be completed in July or August, so you have to listen to his first seven words.

"It seems that the beautiful woman came to our country for a stroll this year. Why haven't I heard any relevant reports yet?" Liu Hai came out of his home in the morning and listened to the news on the radio while driving.

"Logically, it should come in February this year. Is there something that has not been settled?" Liu Hai looked at it and saw that there were already many Kyoto cars on the road.

Among the vehicles on the road now, the most high-end ones are Kyoto cars, followed by vans and pickup trucks.

Then there are three-wheeled motorcycles and two-wheeled motorcycles.

There are also various minibuses, buses, and various types of cars and tractors.

It is rare to see human-powered carts or animal-drawn carts anymore.

A human-powered cart has only two wheels and two handles on the front to pull it forward.

Of course Liu Hai was also curious.

Liu Hai's guess was correct. Some things have not been agreed upon. Coupled with the current domestic environment and the international environment, we are not anxious at all. What is anxious is the other party.

Natuna has already reached an agreement and will issue a joint statement when the United States comes.

On the ball 6 side, no agreement has been reached, and the big brother next door doesn't want the south side to end so soon.

Due to the use of various individual weapons, many advanced weapons of the United States have no advantage. The simplest ones are various RPG rockets. Lao-US helicopters and other tanks, cars, and even personnel have no advantage in the entire south.

If you are not careful, you will be taken away by the RPG, so Big Brother intends to continue bleeding the United States in the south.

Another one is Niu Niu. Niu Niu is causing trouble in Southeast Asia, and he definitely doesn’t want it to stop in the United States.

Because Niuniu knows that once Laomei stops, he might cause trouble for himself.

You must know that at this time, the influence of Laos and the United States in Southeast Asia is still very strong.

Of course, the most uncomfortable person would be Lao Mei, unless he was willing to leave the soldiers and the puppets he was supporting and run away in embarrassment.

But it would be too shameless to do that.

We are now sitting firmly on Diaoyutai, and it will not hinder us from making money anyway.

Moreover, the dealer has also hooked up with many people in the old United States, whether it is the sales of big dog cars, animated movies, toys, and fantasy novels.

In addition, dealers also purchase various raw materials, which is another group of people.

Of course, the main problem with ball retention is the small book. After all, the United States still needs to arm the small book to fight against the Bear Country.

When I arrived at the factory, I first went to the maintenance department to change my clothes, and then drove the car in the factory to the helicopter manufacturing workshop.

Then continue to design the fuselage. The fuselage structure of the Black Hawk helicopter is a semi-monocoque structure, mainly composed of longitudinal members, transverse members and skin.

It can withstand greater damage and maintain its shape. The four main beams running from the front end to the rear end are equivalent to the keel of the ship and are the strongest longitudinal components in the fuselage.

The bangs of the sample helicopter are made of all-aluminum alloy, and the composite materials at the back can be changed slowly.

The best composite material is carbon fiber composite material, but at this time, the technology tree of carbon fiber composite material is not enough.

Of course, fiberglass technology can also be used. Liu Hai is not going to waste time on this in the future and let the helicopter manufacturer slowly optimize it.

Anyway, as far as helicopters are concerned, no matter what material they are made of, as long as they are hit by anti-aircraft weapons, they will basically be over. Whether it's anti-aircraft guns or anti-aircraft missiles.

On the one hand, Liu Hai does not have the energy to do this, and on the other hand, he must leave room for the technicians of the helicopter factory to perform.

If you have done everything yourself, how can others make contributions?

Moreover, it is easier to manufacture all-aluminum alloys at this stage. If it is made of composite materials, there will be no need to take out the aircraft this year.

The nose, fuselage frame, transmission system, tail rotor system, and landing gear system.

The fuselage is divided into the middle fuselage and the rear fuselage. On the bangs side, some of the more difficult parts of the aircraft to be manufactured are designed first, and then let the relevant workshops produce them.

The more difficult part is the transmission system. To maintain normal operation when the helicopter power system is running at high speed, there are very high requirements for the materials, manufacturing and design of the transmission system.

But there is no difficulty for Liu Hai, because not only is he cheating, but he is just copying homework.

This is like when taking an exam. Others are still calculating hard on the scratch paper, but you already know the answer and just write it down.

It takes others ten minutes to calculate the answer to this question, but you only need one second to write it.

This is the current situation of bangs being used as helicopters.

The entire motorcycle factory is fully cooperating with Liu Hai. As long as Liu Hai comes up with the drawings, the relevant workshops will immediately work hard to solve the problem.

Liu Hai has no intention to do other things now because he is too busy.

Liu Hai originally planned to make a radar in the aircraft carrier space, but unfortunately there was no accurate information on the radar antenna materials.

Then Liu Hai can't start with the entire radar's transmission power, calculation model, etc.

So Liu Hai used 4004 chips in the aircraft carrier space to make the control system of CNC machine tools.

The three axes, four axes and five axes of the CNC machine tool reflect its processing coordinates.

Of course, what is also reflected is the processing speed.

Now Liu Hai can only make three-axis and four-axis machining machine tools. The control system is the brain of the CNC machine tool. There is also the servo system, which is a key part of the CNC machine tool to achieve high-precision positioning, including motors, drives, sensors and other components to achieve high-precision positioning. Precision position control and speed control.

Also included is the spindle system, which is the most critical part of high-precision cutting.

There is also the machine tool body, which is the "skeleton" of the CNC machine tool and is responsible for supporting and fixing the workpiece and tool.

Finally, there are auxiliary systems, such as cooling systems, chip removal systems, protection, etc.

Although bangs is not very specialized in the field of CNC machine tools, it is used a lot. As the saying goes, if you have never eaten pork, you have seen pigs run away.

As for the processing program written into the chip, these are actually programmed things. Liu Hai directly found relevant books in the bedroom of the staff in charge of the CNC machining center on the aircraft carrier.

Liu Hai works on CNC machine tools in the aircraft carrier space at night.

During the day, I was responsible for helicopter and manufacturing-related work in the factory.

"Xiao Liu, the dealers are preparing to hand over the 2.0L commercial vehicle to North American automakers." Liu Hai had just eaten at noon that day, and Sun Aiguo was holding his own glass cup, but the outside of the glass cup was black The wool knitted a cup cover, and the glass was a can bottle.

Liu Hai looked at the wolfberries in Sun Aiguo's cup and smiled inwardly. He then soaked the wolfberries in the middle-aged thermos cup.

"I don't have any opinion on this!" Liu Hai didn't express any opinion on these things because he didn't get any benefits from it.

"We will manufacture the family travel version here, but the dealer is not in a hurry." Sun Aiguo said.

Liu Hai nodded when he heard this: "I also think it's best to be steady."

Liu Hai knew that there was an oil crisis in 1973, mainly due to the overlord in the Middle East. The price of oil tripled. In these three years, the industrial production of the United States dropped by 14%, while the small book dropped by 14%. twenty.

Of course, it was also at this time that a huge market for small-displacement cars was created.

Because the price of oil is too high, in fact, before this, small-displacement cars were favored by ordinary people.

Under the impact of the three-year oil crisis, on the one hand, industrial productivity has decreased, and on the other hand, the price of various industrial products has increased due to high oil prices, resulting in an increase in people's living costs.

Of course, small cars, that is, the oil crisis, have shined in the West, because the West did not like small-displacement cars in the past, except for civilians with no money.

Liu Hai feels that the two car manufacturers that produce 2.0L commercial vehicles will probably fall into the trap again.

After all, to produce cars, you need production lines and equipment. These investments will definitely not be recouped next year.

When the oil crisis comes, these production lines may have to stop.

However, Liu Hai thinks this may be an opportunity, because by then we may be able to acquire these production lines at a low price.

At the same time, Liu Hai is hesitant to warn us. After all, we are now an oil importing country.

But Liu Hai thinks about it and forgets it, because some things need to be experienced before everyone has experience.

Moreover, the amount of oil we import at this stage is not too large. After all, the oil production of our major oil fields is still considerable at this stage.

"The sales volume of your fantasy novel has exceeded three million copies. The dealers want to produce toys with the characters in your illustrations in the fantasy novel. What do you think personally?" Sun Aiguo didn't want to disturb Liu Hai, but this concerns Liu Hai. personal income.

"Of course, no problem." Liu Hai didn't expect that the fantasy novel had sold three million copies.

"And the distributors expect you to have a second fantasy novel out within two years."

"But these shameless guys are claiming in newspapers that Jack is their British writer. I really don't know what these guys will be like when the truth is revealed." Sun Aiguo shook his head again and said.

Liu Hai chuckled: "They must have their own methods."

Official cheating is the most deadly, and Liu Hai feels that he might even be honored as an honorary citizen of a city in England.

This can perfectly solve the problem of your own identity.

Besides, Liu Hai will not take the initiative to become famous, because if he stands up and says that he wrote it, believe it or not, a lot of Western writers will stand up and say that he plagiarized it.

Maybe some of my own people will stand up and accuse me of plagiarism. There is no shortage of people like this at any time. The moon in foreign countries is round.

"As long as I can make money, there's no problem keeping my identity secret." A name is not of much use to Liu Hai.

"Your identity is kept secret to begin with, and it seems this is the only way to go."

"The sales of your science fiction novel Moon Rescue are said to be very good, and it is said that additional printings have begun."

"However, the detailed statistics on book sales are said to be slower." Sun Aiguo said again.

"You are working in a factory now, and those dealers and toy factories are working overtime to make money for you. It is unimaginable." Sun Aiguo sometimes looked at Liu Hai's busy figure and thought of foreign factories working overtime to help Liu Hai earn money. Money, it feels weird.

Liu Hai himself took a sip of tea and said, "Maybe it's luck. I didn't expect that they also liked the novels I wrote. It was just that I felt tired from doing the drawings and looking for something else to relax. "

Sun Aiguo picked up the thermos bottle and poured water into his cup: "I sometimes deal with things in the office for too long. I just finish the last thing and don't know what to do next. Sometimes I just stay there in a daze for a long time. Come to your senses and know what to do.”

"Drawing here consumes more mental energy than me doing things over there. You should relax and relax your mind. Later, I went out and walked around the workshop every once in a while, and I felt much better." Sun Patriotic and sympathetic answer.

"Actually, factory director, you can also write something. If you can't write anything else, just write down your personal experience. Let your descendants see how you led the motorcycle factory from a small factory with a few hundred people to a... Now." Liu Hai suggested with a smile.

"The development of our factory cannot be separated from your technology, the efforts of the workers, and the care of the superior departments. I am an errand boy in the middle."

"Besides, you made me scold people. You asked me to pick up a pen to write something and write an autobiography. Maybe I can wait until I retire and study hard for a while before writing. Now that there are so many things happening every day, I can follow you here. Have a good chat.”

"With other people, I just have a loud voice. If you tell some people that they insist on trying to defend you, they will feel uncomfortable if you don't scold them." Sun Aiguo shook his head and rejected Liu Hai's proposal. He might as well smoke out if he had this time. Two cigarettes are comfortable.
