More people is good work, just over a day, this horizontal deep hole boring machine has been installed.

The test material is a metal cylinder more than two meters long, which has been machined to fix the metal cylinder to the fixture.

Then start the test, while testing, bangs on the other hand on the continuous stop to take tools to measure and inspect, and then debugging.

Bangs don't know if Benxi Iron and Steel has this kind of equipment, according to reason, there should be.

However, bangs generally don't ask other peers if they have it, and they really have it.

After half a day of commissioning, the equipment is almost ready, but unfortunately there is no material of the kind that is five meters long.

What Liu Hai doesn't know, China's first boring machine has actually been produced in 56 years, of course, that can't be compared with this, that is the T68 model.

Of course, even if it is the same equipment, the processing accuracy, the processing hole diameter, these are different.

Liu Hai thinks that the boring machine he built should be more advanced in China, mainly because when he does the self-tightening technology of the body tube, the aperture of the inner hole needs to be constantly tested and adjusted.

The trouble of pulling a barrel around is better than building a machine yourself, and you can use it whenever you want.

In addition, subsequent large excavators require hydraulic cylinders that are long enough.

There is also the kind of shield machine that will be going to be done in the next two years, which also requires large hydraulic columns.

This device is definitely not simple to put here, it is to make a barrel.

"Section Chief, do you want to do another test?" Li Dali asked.

"Tomorrow I will go to the factory director and ask him to apply for two materials to come back, let's do it again, we don't have ready-made ones here." This kind of material is not universal, and the equipment department may not be able to be the master, so Liu Hai didn't go there.

Moreover, this deep hole boring machine is made of cast iron, which removes the stress by heating, and does not take a long time to remove the stress naturally when placed outside, so it needs to be recalibrated and repaired after two years of use.

This can't be helped, because the domestic steel industry itself started late, and there is not so much idle steel to put there to remove stress.

Sun Aiguo has not been in his office for the past two days, and has gone to other places, and even to go to work, he has to drive in from the maintenance department and bypass it from inside.

"Factory director?" Liu Hai went to the factory office in the morning to walk around, but he didn't see the factory director come back before he saw the factory director come out of the maintenance department.

"Don't mention it, all those acquaintances in the west, south, and north of the city have come to block the door, don't we have to change the equipment in the factory? These guys are well-informed, if they don't want to give, they look up and don't look down, and they can't give so much. Sun Aiguo shook his head and said with a wry smile.

"Factory director, I have something to do with you, and I want to apply for some materials from you to do experiments." Of course, Liu Hai knows that there must be a shortage of domestic processing equipment now, and a factory has seven or eight processing equipment, and it is okay to produce any industrial products.

It's really not good, and it's good to get two hydraulic presses to go back and stamping lunch boxes.

"If you want any materials, you can go directly to the equipment department." Sun Aiguo waved his hand and said.

"This time the material is a bit special, I would like to apply for two five-meter-long, unmachined barrel blanks." Liu Hai saw that the factory director was leaving, and hurriedly stopped him and said.

When Sun Aiguo heard this, he asked suspiciously: "Wumi, I remember that our factory has materials for the production of hydraulic cylinders?" ”

"The material is different, the longest one is only two meters." Bangs spoke.

"Isn't my side preparing to plan the production of assault guns? When upgrading the equipment this time, I made a horizontal deep hole boring machine by the way. ”

"It is also preparing for the production of larger excavators in the future, and the excavators are larger, and the hydraulic arm is also thicker." Bangs explained.

When Sun Aiguo heard this, he knew that it was not simple, don't listen to what Comrade Liu Hai said, by the way, his way is not simple.

"Let's go, let's go!" Sun Aiguo became interested in this, and he didn't care about other things in the factory.

Coming to the workshop of the maintenance department, Sun Aiguo looked at this big guy and was also a little dumbfounded.

Although it was expected that Liu Hai said that he would process a five-meter long material.

But this big guy with a length of nearly 16 meters and a width of three meters is the largest bedroom boring bed that Sun Aiguo has ever seen.

"Comrade Xiao Liu, this is what you made by the way?" Sun Aiguo looked at the big guy's equipment, and asked while stroking it.

"I'm also taking precautions, and I'll use a lot of places in the future." Bangs said with a smile.

"I'm afraid this is a rare piece of equipment in China, except for some secret military factories, it is estimated that there are no other places, right?" Sun Aiguo walked from here to there, watched carefully for a while, and then spoke.

Then I saw the things processed when I was testing the car next to me, but Sun Aiguo knew how difficult the technical difficulty of the deep hole boring machine was?

There are too many problems involved, which is why the processing of five-meter-long parts, the whole equipment is close to 16 meters, and the length is because it needs to be stable.

"I thought that no matter what experiments we do in the future, it will be more convenient, and we will use more in the future, if we apply for the above to the machine, we will do it ourselves." Hearing this, Liu Hai opened his mouth to explain.

When Sun Aiguo heard Liu Hai's words, he naturally nodded, and if he changed to other factories to ask for equipment, he could only go to his superiors, because he couldn't produce.

"In addition, the crane is also needed, and the inside of the crane boom is also a hydraulic column."

"Okay, is two enough? How many more? When Sun Aiguo heard this, he asked again.

"Of course, no problem, let's have a few more." Liu Hai thought to himself, anyway, he would have to do a barrel test in the future.

Sun Aiguo lowered his hat, wore factory work clothes to the temporary office, and directly took the phone to report to the superiors.

When the leader heard Sun Aiguo's request, he immediately agreed, and at the same time asked curiously.

After all, the five-meter-long barrel material is not an ordinary material, and it must have a relatively large diameter.

The leader hung up the phone, touched his chin, and of course knew what it meant to be able to process a five-meter-long deep-hole boring machine.

And the leader believes that what comes out of the motorcycle factory is definitely not an ordinary product.

At present, the domestic buying units know that the original products produced by the motorcycle factory are much better than the quality of the products produced by other auxiliary factories.

Because the motorcycle factory has always taken care of the export business, as long as the unqualified products will be re-smelted into materials, and then reprocessed, no unqualified products will be allowed to leave the factory.

Other factories are not good, as long as everything that can be used must be shipped, which is not to say that the standards are not strictly enforced, but now the demand is too great.

The director of Haier refrigerator smashed the refrigerator to see the industrial environment at that time, this is still the later era, not the sixties and seventies now.

Therefore, the products from the motorcycle factory are more popular, but now the motorcycle factory is basically all exported, and there are basically very few products that can be obtained from the motorcycle factory in China.

Excavators have also been exported, and a bunch of poor brothers in the mainland in the world, not to mention the excavators of the ninety, are all high-tech steam excavators left over from the former colonies.

Therefore, the excavator in the mainland is very popular on the poor brother's side, after all, the mainland is half bought and half given, and the cost price can be charged.

The mainland's reputation in the international community is still very good, and after beating the third brother in history, the third world countries have opinions about us, and now there is no one in the third world to help the third brother speak.

After all, your third brother didn't sell me an excavator cheaply, a tractor at a low price, and a motorcycle, so why should I talk to you?

In fact, it's really not that the third brother doesn't want to sell things, but after this scene, many rich people have run away, it is said that all the rich people in the whole city at that time have dragged their families and run away, even the poor have also run, and the city is even more chaotic, and many shops and factories have been robbed.

It is said that even the army in the city ran faster than the inhabitants.

Many leaders of third world countries ride in ZTE luxury off-road vehicles.

Historically, there have not been so many fist products in the mainland that have been welcomed by third world countries.

The most depressed is the big brother, who originally thought that there would be no way to withdraw the experts to the mainland for development, who would have thought that people would be prosperous and export products better than themselves.

A week later, a six-meter-2 truck drove into the motorcycle factory.

I brought the samples I wanted, and there were as many as 20 bangs, all of which had been rough-processed.

The truck drove directly to the maintenance department, and the people from the maintenance department first carried out further processing of the rough barrel, and after grinding and grinding to achieve sufficient accuracy, they were then put on the boring machine.

The deputy director of the motorcycle factory in charge of military products, as well as Sun Aiguo and others, looked at a five-meter-long cannon barrel that had been processed and placed on top of the equipment.

Liu Hai took Li Dali and a few people to debug and calibrate again, and then started the machine.

There is not a machine, but also a processing technology, the speed of processing is crucial, if the processing is too fast, not only the cost of equipment, but also because of the high temperature will have some impact.

If the processing is slow, there is nothing to do, but it will delay time, so you must have a suitable speed.

After the processing was completed, Liu Hai took Li Dali and others to test it.

"How?" Sun Aiguo saw that Liu Hai and the others had finished testing, and asked anxiously.

"There's still a little bit of a problem." Bangs shook his head.

Of course, the bangs are not made as a barrel, but as a test equipment.

The production process of the gun barrel is very complicated, and the production process of the smoothbore gun barrel is as follows: primary tube drilling - heat treatment - straightening - turning - flaw detection - deep boring - shaft furnace annealing - hydraulic self-tightening machine.

Bangs this is just a test of the performance of the equipment, of course, there is no final step of the process in this era, because that kind of machine has not been manufactured for the time being.

"What's the problem?" When Sun Aiguo heard this, he asked a little nervously, isn't this big guy useless?

"Our technology is not good, the inner wall of the processing is not smooth enough, and there are some small defects." Bangs shook his head and said.

To make the inner wall of the barrel like a mirror, it requires the superb experience of skilled workers, and the skills of Liu Hai and others are not very good, so the processed products have some small flaws.

"Is there a problem with the device?" When Sun Aiguo heard this, he breathed a sigh of relief in his heart and hurriedly asked.

"There is no problem with the equipment, and the processed hole diameters are all up to standard." Bangs holds the data recorded on the notebook.

Sun Aiguo breathed a sigh of relief when he heard this, and the deputy director in charge of the military industry in the factory also breathed a sigh of relief.

"Is this kind of equipment capable of producing energy?" Sun Aiguo asked again.

"Mass production is not a big problem, but the output of this equipment is relatively low, and the requirements for workers are relatively high." Bangs spoke.

This kind of processing technology completely depends on the worker to look at the shape of the cutting to judge whether there is a problem.

The average novice will do this, and most of them will be wasted.

"We don't have a lot of demand for this, and the workers can only be cultivated slowly." The deputy director in charge of the military industry spoke at this time.

"We can produce as long as we need to." That's all said and done, of course Liu Hai has no opinion.

"Good job, Xiao Liu, this kind of equipment is in demand in our military industry, especially this model." The deputy director in charge of the military industry is not a person from the factory, but from the ministry.

As for which ministry it is, of course, it is in charge of the military industry.

As for how long it will take to produce this kind of equipment, and how much it will be produced, there is no plan on the spot.

What equipment is going to be produced now? It's not like placing an order on the spot or anything, because the materials and everything have to be planned.

Even now, production can only be produced when the materials are in place.

That is to say, there are more material plans on the motorcycle factory side, and some of the materials can be taken out to produce equipment first, and then the planned materials in the follow-up department will be returned.

If you change to other general factories, you will be given as many plans as you want this year.

Because it is very troublesome to change the plan, simply one or two factories change the plan, then there is a mobile material plan in the ministry.

If there are more enterprises that change their plans, the work of the superiors will be disrupted, because from the upstream enterprises to the downstream enterprises, they were all planned last year, and now you say how to change them?

Then Liu Hai found that the back of this boring machine did not belong to him, but said that it was still on his own turf.

"Xiao Liu, they are just here to use this machine temporarily to see the performance of this machine." The deputy director in charge of the military industry also greeted him in advance.

When these people came, they brought a lot of all kinds of materials to the barrel, and then they started processing them in the workshop over there.

"Xiao Liu, is there anything better than a high-pressure sodium lamp?" Sun Aiguo came to the maintenance department, looked at the bangs drawing, and asked.

"Director, why are you asking this? We don't produce? Liu Hai asked curiously, and the high-pressure sodium lamp had already been handed over to other factories for production.

"My superiors asked me to ask, Big Brother has imported a lot of high-pressure sodium lamps from us over the years, but they all complained that they consume more electricity." Sun Aiguo opened his mouth to explain.

When Liu Hai heard this, he asked in wonder: "Big Brother has been importing all these years, and they don't produce it themselves?" ”

"This is not clear, anyway, there are a lot of imports every year, and the factory that used to build high-pressure sodium lamps was only 200 people, but now it is said that there are 7 or 800 people, and the task is still very large."

"Big brother, how many plant factories have you got?" When Liu Hai heard this, he felt that something was wrong.

"It is said that dozens of crops have been planted, and there are even tropical fruit trees, and it is said that they use greenhouses to raise pigs and cattle very well."

"And Big Brother is said to be able to provide a lot of fresh vegetables and fruits every winter, and the leader of Big Brother has a good reputation in their country now." Sun Aiguo's words surprised Liu Hai, isn't the corn going to be yellow?

But then I thought of LED lights, which are expensive to manufacture in the mainland, but Big Brother can definitely do it.

"I have an idea here." Liu Hai touched his chin and said, Actually, corn has a good relationship with us now, and it will be even worse if we change to the next one, and it is okay to help corn.
