Chapter 289: Zhao Yanyan's New Position (Part 1)

Hanging vertically for storage and transportation is afraid of deformation during storage and transportation. Generally, slender shafts are preserved in this way. After all, whether the slender shaft or the barrel is heavy, under the influence of its own weight, it is inevitable that there will be slight deformation.

The sniper barrel requires high precision, and may even use a suspended barrel, so it is normal for the barrel to require high strength. When the soldiers use it, it must be used flat and will not stand up, but this does not mean that it will not be slightly deformed.

Guo Tailai would rather pay more attention to precision instruments when they are not in use, especially before they are installed on firearms. They must be able to maintain the maximum accuracy and try not to reduce the accuracy in other ways.

There is one thing that Guo Tailai didn’t say, it doesn’t matter what Zhao Xiangbei said, because he is a layman in processing, he is in charge of overall management and sales, if those designers and producers also have the same idea, then this sniper The accuracy of the gun does not need to look at Guo Tailai to know how bad it will be.

"Didn't you improve it?" Zhao Xiangbei didn't distinguish anything, but he and Lu Zhiming carefully fixed the vertical packaging box, and asked casually.

"Improve what?" Guo Tailai asked in confusion.

"Gun barrel!" Zhao Xiangbei was taken aback, and made two gun barrels. What else could it be?

"What's wrong with the barrel design?" Guo Tailai was also stunned. How to improve the design? In which direction to improve?

"I don't know." Zhao Xiangbei shook his head: "However, aren't you used to improving firearms?"

"Then you have to know what the problem is before you can make targeted modifications?" Guo Tailai finally understood Zhao Xiangbei's meaning, seeing that he could come up with a better version of what he did, so he took it for granted that the barrel could also work. improved. But isn't this too compelling? Don't know the overall design requirements, just take a blueprint and let it be improved, isn't this what makes Guo Tailai feel like a blind man?

Zhao Xiangbei also realized that he was taking things for granted, so he chuckled, threw a pancake fruit to Guo Tailai, and drove away directly. Guo Tailai watched the two leave in a very speechless manner, and then started to eat the pancakes. Fortunately, he hadn't eaten breakfast yet, and Zhao Xiangbei knew to add an extra egg for breakfast.

After breakfast, Guo Tailai continued to go to the hospital regularly, and in the morning he had to go round with the teacher. Although Guo Tailai was interested in the matter of sniping the barrel, he thought that the research institute must have been researched and developed for a long time, and it was absolutely impossible for Guo Tailai to join in and get a share of the pie, so he gave up. Besides, during this period of time, we should honestly pass the doctor's qualification test first, and then we should not make extra troubles.

Here Guo Tailai is very calm about what he should do, and he doesn't feel that what he is doing is so great. Over there, the two gun barrels made by Guo Tailai have been urgently sent to a certain laboratory for inspection and assembly.

"The gun barrels are delivered?" A researcher took the two vertical packaging boxes from Lu Zhiming, and couldn't help but said happily: "Quickly arrange an inspection to see how accurate and high-quality the gun barrels are in this batch! "

Lu Zhiming's face turned dark, but he didn't say anything after all. These researchers did not know that the barrel of the gun was made by Fatty. It is understandable for people to test the quality and accuracy, but this made Lu Zhiming, who is familiar with Fatty, a little uncomfortable. Do things made by the fat man still need to be inspected? I really have never seen the world.

In any case, inspection is a necessary process, it must be done, and the inspection results must be recorded in detail. But when Lu Zhiming saw that someone wanted to measure the inner diameter with a vernier caliper first, he finally couldn't help it.

"Don't use vernier calipers." Lu Zhiming reminded loudly, almost startling the person in charge of the measurement. How can there be some scratches if you use a vernier caliper to directly press it?

Guo Tailai even had to hang it upright for transportation to avoid slight deformation. These young surveyors are so ignorant of other people's labor results, isn't it too much? So irresponsible?

Lu Zhiming, the military representative, was quite intimidating. The young people who were inspected were reminded by Lu Zhiming, but they stopped using the vernier calipers. But he also seemed a little upset, and murmured in his heart, "Do you test or should I test?" But under Lu Zhiming's nose, he honestly began to record with professional instruments.

"Length, qualified!"

"Outer diameter, qualified!"

"Straightness, qualified!"

"Concentricity, qualified!"

...

"Wrapping horns, qualified!"

"Machining accuracy, qualified!"

A series of qualified results were reported, and the final conclusion was that the two barrels were qualified.

Lu Zhiming listened beside him, not even anger in his heart. Mr. Zhao spent hundreds of thousands of dollars to specially invite Mr. T Guo Tai to build two limited-grade gun barrels, but they are only qualified? Is this a big joke?

"How's the quality of the gun barrel?" An older researcher pushed the door in and asked several young people in charge of the inspection.

"Qualified!" The young man who was muttering in his heart just now replied quickly.

"Just qualified?" The researcher who came in frowned slightly: "Didn't you say to arrange a batch of high-quality products? Forget it, let's install a live ammunition test!"

"I suggest you better measure it again." Lu Zhiming reminded the newcomer, who was older.

The older researcher was taken aback for a moment, looked at Lu Zhiming, and then at the young people in charge of the measurement, suddenly seemed to realize something, and said to a few people: "Bring it here, let me have a look."

As soon as he got his hands on the gun barrel, he immediately noticed that it was unusual, so he didn't use any measuring instruments, so he directly looked at the inner wall of the gun barrel with light, and saw that even the small inner grooves of the rifling could see the reflection evenly, and it reached the mirror surface by visual inspection. When it works, it explodes immediately.

"How did you measure it?" Carefully keeping the barrel vertical, the researcher who came in later started spraying: "You actually said that the barrel of this level is only qualified? Who taught you the measurement method? How high is your standard? Do you still want to do it? If you don’t want to do it, pack up and get out!"

With a swearing, several young surveyors who were dissatisfied with Lu Zhiming's reminder and tossing deliberately scolded the head of blood. It was not until the scolded young people couldn't lift their heads that the researcher turned around and asked Lu Zhiming.

"Which factory is it this time? Representative Lu?" Several factories have been tested before, and they can produce qualified products, but they are only qualified. It seems that the design performance cannot be perfectly realized. The quality of the barrel this time is extremely high. Gao, maybe there is hope for the completion of the design, and the researchers are also very excited.

"Secret." Lu Zhiming smiled, but still reminded: "But I can guarantee that if there is a problem, it will never be the processing quality of the barrel. Hurry up and arrange a test!"
