This is simply a machine tool exposition, but all these equipment are from Europe, not only the member countries of the Soviet Union, but also some countries of the European Community. Obviously, these devices from the countries of the European Community have been produced only in recent years!

"Xiao Jiu'er, what are you doing in workshop A? These are all reserves of some industrial machine tools used to manufacture machine tools...... "Just when Liu Yijiu realized the problem because he didn't find those general small machine tools, Yang Shan, who was holding two silver-white aluminum rods in his hand, walked in with an old man who Liu Yijiu felt a little familiar.

Regarding Yang Shan's question, Liu Yijiu couldn't answer. You can't tell him that you don't know how the machining workshop is divided and where it is, right?

"Okay, it doesn't matter what this base is for, our current level is not enough, and when the level goes up in the future, we will naturally be able to know what is in it." Let's think about how to process this now. Don't delay it too long, it's not good if too many people see it. Yang Shan's words touched on the thing that Liu Yijiu was most unwilling to face.

He is not the real Liu Yijiu, and there is no way to express his true feelings about this matter. Otherwise, a lot of flaws will be exposed.

At this point, it's wisest to change the subject.

If you don't hurry up and get the simple muffler out when no one is coming, you will be in trouble when someone comes to work.

It's okay for one or two people to fool around like this, but if there are too many people, they will inevitably be exposed.

No one in this base dares to say that the proportion of all elements of Lao Maozi's aviation aluminum can be analyzed, and the production process can be studied.

It's okay to brag about B, and it doesn't matter if you pretend to be B to a few people, but you must not let too many people know, otherwise it will become a difficult situation to ride a tiger.

They are young, newborn calves are not afraid of tigers, bragging, everyone can understand. If there are not many people who know, you can just use a sentence to give up and fool the past, and others just shake their heads and smile. If everybody stares at them and waits for them to come out with a result, they're going to analyze a piece of! I don't know how to do physical and chemical analysis!

"You can't do it, although the accuracy of this Romanian lathe is OK, but it is not easy to operate, especially the copper tile used on the spindle head, and the temperature is high and it will be locked, which is a problem. Besides, your thing is so small that it can use a one-meter heavy car? Seeing Liu Yijiu pay attention to the largest 61100 horizontal lathe in the workshop, Yang Shan couldn't help but feel a little depressed.

"This thing was made in Moscow in 1943! This is a classic machine of more than 30 years! ”

"This one has been modified. Forget it, let's study it slowly when you're full! "For such an antique classic machine, Liu Yijiu is definitely very interested.

It's just a pity that in his time, in the sixties and seventies of the twentieth century, domestic classic aircraft and imported classic aircraft could be obtained, and imported equipment before the founding of the People's Republic of China was really rarely seen.

Especially these small machining machines.

"Use 20 or 16, will you kid use it?" There are not many ordinary lathes in the workshop, six C616 and four C620, which are also from various countries, and even one of the 616 lathes was produced in Japan in Northeast China in 1937!

The exterior has been repainted, and by feeling, the quality of the classic machine produced by Japan in Northeast China during the Anti-Japanese War is absolutely reliable.

"Shut up, don't you see I'm working on what to do with this thing?" Liu Yijiu basically hasn't even looked at these antique equipment, let alone operated.

At the end of the 21st century, most of the machining equipment was automated CNC equipment, and even a few manually operated machine tools used for some high-precision and cutting-edge mechanical parts processing experiments and single-piece small batch production were very different in terms of structural principles.

What's more, those equipment can only be well controlled by masters who have undergone a long period of professional training.

Liu Yijiu was originally engaged in research, not a front-line technical worker who operated machine tools, how could he not be dumbfounded when he saw these old antique machine tools?

He thought he could get some antique lathes up and running the muffler, which basically had no precision requirements, but it was different from what he had seen before!

What's more, these are all imported, the joystick or anything is not what he is used to, and he hasn't even found the machine tool switch button, so it's strange if he is not dumbfounded!

"Comrade Xiao Liu, this is not a joke! We took such a big risk, you have to study how to use it now, isn't this shabu shabu for our brothers? The 16 over there has a knife on it, so you can just use that one. Yang Shan didn't know what Liu Yijiu was like, thinking he was joking.

Liu Yijiu was different from them, he instinctively believed what Liu Yijiu said.

He thinks that Liu Yijiu can process these simple sets, but this guy has just arrived at the base, and he should have never seen so much advanced equipment, and he just feels a lot. Yang Shan instinctively found an excuse for Liu Yijiu.

Seeing Yang Shan running to the edge of a Japanese classic lathe with the most old appearance, that is, the Japanese made in the thirties, with a turning radius of 160mm and a maximum processing of 320mm, he twisted a knob under the headstock, and the working light on the lathe suddenly turned on.

Involuntarily, Liu Yijiu walked towards the front of the small lathe, at this moment, as if he was possessed, he felt that this lathe was too simple!

didn't speak, took a bar from Yang Shan's hand, picked up the chuck wrench and clamped it on the chuck, and then pulled the two handles of the selection spindle to the second highest speed of the lathe at 1400 rpm on the gear, and then the control of the spindle forward and reverse rotation and stop of the control handle to the forward rotation, in an instant, the lathe roared!

"The gear in the headstock is a bit worn, and the beating of the spindle is okay, so it shouldn't be a big problem!" Seeing that the chuck connected to the spindle told the rotation and there was a slight jump, Liu Yijiu seemed to be a different person, while quickly adjusting the handle that controls the speed of the knife while analyzing.

"You go and help me get the drill bits and reamers listed above, and I'll rough the car first. I'll go, I forgot that there is no muffler thread on the barrel, Brother Yang, you still have to go over there, so that you can't eat enough to remove the barrel, otherwise it's useless to do a good job, and you can't install it......" At this time, Liu Yijiu realized a problem.

Old-fashioned rifles were designed without a muffler in mind!

The five and a half that are widely used in China did not consider this problem, and some of the six-eight types imported from the Soviet Union later could, but the gun was quickly eliminated by history because of performance problems......

"Brother Yang, Xiao Jiu'er ......"

At this moment, Luo Tong cautiously ran into the workshop like a thief, and looked around to see if there was anyone as he ran.

Typical devils enter the village.

"Why are you here? Didn't you wait outside? Yang Shan thought something had happened.

"I couldn't get enough to get the gun, there were no bullets in the three-eight big cover, I got a five-and-a-half-half, and I was worried that the muffler I made happily wouldn't match, so he removed the barrel and let me bring it in......," Luo Tong hurriedly explained.

It is difficult for them to process a gun, and it is not a problem to remove the barrel.

"You said you ......" This is very easy to expose, Yang Shan was about to count Luo Tongtong, but Liu Yijiu praised Luo Tongtong with a happy face: "It's just right, I was still worried about this problem just now." There will be no problem with the barrel to cooperate. ”

Liu Yijiu said this, and Yang Shan naturally didn't say anything more: "That's okay, Luo Tong, you come to help, I'll go to the door of the workshop and stare at ......"

After speaking, he didn't care about the reaction of the two, and went directly to the outside.

"This guy is really, every time like this, cheating and slippery. When the time comes, if you dare to shirk responsibility, you will be good-looking! Luo Tong rolled his eyes at Yang Shan's back, spat with disdain on his face, and muttered quietly.

When Liu Yijiu heard this, he smiled helplessly.

Yang Shan's situation is different from theirs, relying on the drill camp and marrying the daughter of their village chief to obtain the qualification to be recommended to go to university, and most of the monthly salary and food stamps are sent home. Once something happens and he is sent back, he can't afford the loss. Unlike the two of them, who are not full of food and Luo Tong, they are both masters who feed the whole family without hunger, and it is normal to be cautious.

"Alright, quickly find out the drill reamer listed on this, and besides, you measure the diameter of this barrel, find a plate tooth to process a few threads out of the port. Find out the tap, the end of the sleeve has to process the internal thread, otherwise it will not be able to connect...... "Time passes more and more, and it can not be delayed any longer, and it is easy to be found when you go to work for a while."

After the division of labor, Liu Yijiu didn't care if Luo Tong could find these quickly.

The muffler should have been made of carbon steel or stainless steel, but in order to make it easier to process, Liu Yijiu chose aviation duralumin. It won't be used for a long time anyway.

Only by using a threading cutter can the thread be processed to ensure better accuracy, and by boring the hole with a boring cutter, the inner surface can be smoother, thereby increasing the service life of the muffler. These are now Liu Yijiu's incarceration.

He only hoped that it would be done as soon as possible, and it was very likely that he would be found out if he stole a gun from the warehouse and went out hunting, even if they said it was an experiment and did not report it, it would be unjustifiable.

It can only be said that the temptation of eating meat, or filling their stomachs, is too tempting for them, if it weren't for the fact that the base has begun to implement the rationing system, Yang Shan would not have taken risks with them.

Without paying any attention to Luo Tong, Liu Yijiu began to operate. He didn't know what was going on, and the moment he touched the handle of the lathe, it was as if the whole world had disappeared, and it was just him and the lathe in front of him. A familiar feeling arises!

"I'll go, I'm not mistaken, right? Xiao Jiu'er is so skilled in driving the bed! Where did he train? After hearing the lathe roaring again, and seeing Liu Yijiu's smooth and artistic operation, Luo Tong, who was looking for a drill and reamer in the tool cabinet next to him, couldn't care about the things in his hands.

Like those masters who have been working for decades, Liu Yijiu hunched his waist, shook the large pallet handle of the transverse feed of the lathe with his left hand, and shook the middle carriage handle with longitudinal feed with his right hand, the whole action looked extremely coordinated and had a very harmonious feeling. And, the action is fast!

Even for ordinary young workers who have turned into regulars, the action of operating these lathes always gives people a stiff feeling.

The hands kept moving, the body basically did not move, and the body would only move when the spindle speed was shifted or the feed speed was adjusted, which dazzled the already dumbfounded Luo Tong.

When the machine stopped to shift the spindle, Luo Tong saw that Liu Yijiu held the left hand of the spindle motor lever and pressed the handle down gently, and there was a very short pause in the middle, and then pressed it in the direction of the reversal of the spindle below, and then lifted it quickly.

The spindle, which rotates at a high speed of more than 1,000 revolutions per minute, completely stopped in less than two seconds!

Immediately afterwards, Liu Yijiu used both hands and feet, holding the chuck with his left hand, pulling the small handle to adjust the automatic feed speed with his left hand, and kicking the two spindle gear set adjustment handles used to adjust the spindle speed at the same time!

Eighth-level lathes don't necessarily have such a bullish operation! At this point, Luo Tong is sure, after all, most of the lathe workers here are level eight!

Is this guy still human?

"Did you find the drill? Hurry up and put the cone on it, and cut it ......off after drilling," Liu Yijiu's voice pulled Luo Tong back to reality from shock......
