Qin Xiaowei said nothing, just pursed his lips, and Tang Jichen's face was full of grievances that could not be concealed: "What is cost-effectiveness? Do you know how much Xiaowei suffered and how many crimes he committed for the universal machine gun?

Not to mention anything else, just for the rollers in the gun, his hands almost lost a layer of skin, and once again his fingers were almost removed by the grinder. If you don’t believe it, see for yourself!”

Tang Jichen couldn't help but grab Qin Xiaowei's hand behind his back and flashed it to Bai Yi and Zhu Yingqi. Looking at the fingers wrapped with a few gauze and the smooth hands with almost no visible hand lines, Bai Yi just frowned slightly.

On the contrary, Zhu Yingqi looked stunned: "This hand actually..."

Zhu Yingqi wanted to find an appropriate adjective, but after a few clicks, he couldn't find the right word. It wasn't that Zhu Yingqi didn't have enough education, but Qin Xiaowei's hands simply didn't look like human hands.

It is neither white nor gray. There is a shallow layer of callus-like substance attached to the smooth surface. The trembling of red flesh and blood can be seen clearly in several obvious depressions. One glance at it will inevitably make you want to suck it for a few times.

Mouth is cold.

"It must be Master Lei's craftsmanship!"

Bai Yi didn't say much, just asked lightly.

This time, before Tang Jichen could help answer, Qin Xiaowei gave a serious hum and nodded.

As Tang Jichen said, in order to complete the universal machine gun, Qin Xiaowei really suffered a lot. Notwithstanding the complicated and precise theoretical calculations, the most critical thing was the processing difficulties.

Among them, the rollers in the gun have the highest accuracy requirements. The error accuracy must not exceed 0.05mm. This value is equivalent to the diameter of an adult hair. In other words, the surface of the two rollers is connected to the level of a human hair.

No defects are allowed.

This requirement will be met decades later in the early 21st century. Even a factory without any background will not be able to produce such precision, let alone the current era of poverty and nothing.

Therefore, Qin Xiaowei suffered a bloody head injury from the beginning, and even had another sample test, because the roller processing was not up to standard, resulting in a deviation in the unlocking, and the entire gun exploded in the chamber, almost blinding Qin Xiaowei who was doing the test himself.

Here.

In this regard, Qin Xiaowei has not thought of a solution, which is to use German-made precision machine tools to improve the processing accuracy. He has tried it no less than dozens of times. However, it is not easy to improve the accuracy to a few tenths of a millimeter. Without a computer,

As an auxiliary, without the support of precision parts and relying only on a few old machine tools that have been exposed to wind and rain in the wild for several years, it is simply impossible to achieve.

Qin Xiaowei, who had experienced several failures, gradually understood this truth. Although it was a bit cruel to him, he still had to accept this cruel reality. But just when he was disappointed to the point of despair, Master Lei from Baiyun Factory's unique skill...

Let Qin Xiaowei see the hope of realizing his dream.

It was a rainy afternoon in autumn, and the Korean front line where the fierce fighting was going on urgently needed a batch of 155mm and 150mm artillery shells to facilitate the normal use of the US-made 155mm artillery and the German-made 150mm artillery.

At that time, the Soviet Union did not have production lines for these two calibers of ammunition, so there was no hope of importing them. It could make up for it by relying on seizures. However, after the US military suffered heavy losses in the first and second battles, its artillery deployment became more flexible.

, there was nothing wrong with it, he immediately loaded up the truck and left, leaving all the so-called fire support to the air force in the sky.

As a result, the idea of ​​using seizures to make up for the shortcomings became empty talk, so we had to produce them ourselves.

As a military factory integrated into the logistics system of the Volunteer Army, the Baiyun Factory accepted this task without hesitation. The caliber of the artillery shells, the charge of the barrel, the specifications of the explosives, the composition of the shrapnel, etc., were not frowned upon by the Baiyun Factory.

But when it came to the most important production stage, a major mistake occurred.

Due to insufficient processing accuracy, the quality of the ammunition belt was not up to standard, and the chamber exploded during the test firing of the artillery shell, directly destroying a valuable American-made 155mm howitzer.

Such a heavy loss was naturally strongly reprimanded by the Volunteer Army Headquarters and the General Staff, so much so that Song Jixue, who had just taken over as factory director, was subject to intra-party inspection.

At that time, the military chiefs who were still in Pyongyang, North Korea, had packed their luggage and were preparing to return to the country to deal with this matter personally. Even Bai Yi, who was on the Tiewon front line in charge of trapping US military helicopters, received an urgent telegram to return home at any time.

With such a wide range of involvement, one can imagine the pressure the Baiyun Factory was under at that time. However, the problem was that the Baiyun Factory did have shortcomings in high-precision machining, and American-made and German-made artillery were surprisingly precise, so that the shells on the shells were

A slight deviation in the belt will lead to insufficient tightness between the shell entering the chamber and the gun body, which may result in insufficient sealing, resulting in ineffective shooting, or in severe cases, the chamber will explode directly, causing the gun to be destroyed and people killed.

However, when the Baiyun Factory was at a loss, the old fitter Master Lei stepped forward, braved the lingering but chilling autumn rain, and used his famous "Thunder Right Hand" to first touch the bores of the American and German artillery.

Then he repeatedly touched the shell belts of the two artillery pieces.

Finally, he squinted his eyes and opened them slightly, pointed to a place, and ordered to his apprentice Ren Xudong: "Here, file four passes!"

Four lines is 0.04mm, which is the diameter of an adult's hair, but Master Lei figured out this value with his almost dry right hand without any measuring instruments.

What's more important is that the whole process only lasted a minute or two. If it weren't for the name Master Lei, everyone present would have thought that the old man holding the cannonball was joking.

Not to mention Qin Xiaowei, even Master Lei's apprentice Ren Xudong couldn't believe that his master could get the numbers accurate to this level, 0.04mm. What kind of hand is that? A sci-fi hand equipped with precision instruments?

Therefore, the two cadres of the Volunteer Army Logistics Department who were present at the time immediately raised questions. However, Master Lei smiled slightly and did not need Ren Xudong to step forward. He directly picked up the file, filed it on the left and right sides of the belt a few times with ease, and then took the file.

He threw it on the workbench and said proudly: "Take it and beat it. If there is any problem, you can just pluck my head off!"

Two cadres from the Logistics Department of the Volunteer Army, you look at me, I look at you, no one can be sure to pay attention. In the end, the factory director Song Jixue took the pressure and made the guarantee, and then treated a dead horse as a live horse.

Attitude, he pushed the cannonball that Master Lei had personally filed into the barrel.

The shot was fired from the barrel and a cannon was fired. The whole process was like flowing water. Everyone present was dumbfounded. A large group of people had been busy working on a problem that could not be solved for two months. Master Lei just touched it and filed it.

, so I still tolerated it.

This gave many people an indescribable sense of fantasy. They really believed that all of this was real. But when the shells landed and rumbled, everyone including Qin Xiaowei was blown back to reality. But because of this,
Chapter completed!
