The current situation is self-evident, Wang Sheng and Luo Zhang did a ghost on the precision machine tool, and the means are extremely despicable, constantly destroying the optical scale of the machine tool, how can this not cause the anger of the Wanshan factory workers present, one by one, gritting their teeth, eager to swallow these two scum alive.

Seeing this scene, Luo Zhang was already so frightened that his legs were weak and he fell to the ground again, but Wang Wei was still pretending to be calm, because he still thought that there was the last straw in his heart, that is, no one in Wanshan Factory would operate it, because of this, when Lu Jiadong unraveled the truth, Wang Sheng didn't think so, but became even more arrogant:

"How about us? Who of you can operate such a scale without us?" Seeing that no one answered, Wang Sheng laughed, and his contempt was overflowing:

"You guys are operating, operating! Haha, a small factory is a small factory, and in the end it's still"

As he spoke, his voice suddenly became smaller and smaller, not because someone was not used to beating him, but the machine tool not far away suddenly sounded inexplicably, and when he turned his head to look at the machine, he saw Lu Jiadong skillfully fiddling with the various parts of the machine, which was a hundred times stronger than the master he had seen.

Just when he was surprised by Lu Jiadong's mastery of the machine, Lu Jiadong had turned off the machine tool, took out a small metal pipe from it, didn't look at it, and threw it at Wang Sheng, although Wang Sheng has a problem with his character, but the technical aspect is still very good, just glanced at it, he knew that this pipe was a qualified product, and he couldn't help but be qualified, and the precision and quality of the processing far exceeded that of a master like him;

"How is this possible!"

Just as he was holding up the metal pipe and looking at it in surprise, Lu Jiadong's words clearly reached his ears: "You two have been fired from Wanshan Factory, now you can pack your luggage and go back to Guinan Factory!" Hearing Lu Jiadong's words, Wang Sheng's eyes were dark, and he instantly collapsed to the ground

The moment Lu Jiadong exposed Wang Sheng and Luo Zhang's methods, the fate of the two was doomed, although the "dismissal!" that Lu Jiadong said was not popular at the moment, but it is not difficult to understand the literal meaning, that is, let these two bastards get out, Chen Zhen was even more furious after understanding the reason.

Originally, he was a person who couldn't rub sand in his eyes, but he didn't expect two moths to squat in front of him, which was worth it, not to mention that Wang Sheng and Luo Zhang were driven out of Wanshan Factory that afternoon, not to mention the medical expenses, even this half a month's subsidy, Wanshan Factory did not give a point, not only that, Chen Zhen also sent a telegram to the old factory director Zheng Yongbo, explaining the situation of these two people, and those who know Zheng Yongbo know that when he sees this telegram, these two people will be punished more severely!

Wang Sheng and Luo Zhang dragged their bodies covered in bruises like this, and rolled back to the Guinan Factory in a gray manner, and the Wanshan Factory quickly forgot these two bastards in the corner, because they invested in the research and development of grenades that matched the grenade launcher, of course, Lu Jiadong had more than just a gun-mounted grenade launcher on hand.

There is also the simplification of the production of 78 firearms, this kind of thing is not a difficult thing for him, within a few days to do a good job of simplifying the process of technical model, due to the use of a large number of stamping parts, the cost of firearms has been greatly reduced, and the original 500 yuan has been reduced to the current 240 yuan, if large-scale mass production, Chen Ben will further decline.

After simplifying the process of the Type 78 firearm, Lu Jiadong focused on the fuse of the grenade, according to Lu Jiadong's original idea, the fuse of the 40mm grenade is best to use the radio proximity fuse, so that the grenade can explode over the enemy, and the lethality will be multiplied, but this plan was quickly vetoed by Lu Jiadong.

The reason is nothing else, the main reason is that the technical conditions at that time did not allow it, the 40mm grenade was originally small, the warhead fuse was even smaller, and the radio proximity fuse needed an integrated circuit board, and such a high-performance circuit board was stuffed into such a fuse with a diameter of more than 20 millimeters, not to mention our Wanshan factory, even in the whole country, no one can do it!

Thinking of this, Lu Jiadong couldn't help but sigh, the country's electronic technology strength is really too backward, but no one can eat a fat man in one bite, and if you want to change, you can only take it step by step.

As a military industry expert of later generations, Lu Jiadong was very familiar with all kinds of collision fuzes, especially the 1-95-DRK42 collision fuze used by the DFS-10 type 35mm grenade commonly equipped by our army in later generations.

Because of this, Lu Jiadong designed effortlessly, after all, the design of the fuze was like being burned in his mind, and soon the sketches of the key components of the fuze, such as the fuse, the connecting rod, the pill box, and the positioning pin, were drawn by Lu Jiadong, and Lu Jiadong also installed a time-delay self-destruct device similar to a clock in the fuse, with a delay time of about 15 to 20 seconds, of course, the detailed design drawings Lu Jiadong would not draw, so this arduous task was handed over to Yang Limin and several other draftsmen.

This kind of fuze is not difficult to design, after all, there are only a few principles of collision and explosion, as long as the boring pressure and the resistance parameters of the projectile in the air are calculated, and the fuze insurance can be set, not to mention the design drawing, all the data are listed by Lu Jiadong, as long as you hold a ruler and pencil drawing.

If you want to say difficult, it can only be difficult in the production and processing, more than ten connecting rods, springs, bumps, firing pins and other mechanical parts in the fuse should be concentrated in a space with a diameter of only more than 20 millimeters, not only that, but also to install gunpowder, self-explosives and **, so the parts in the fuze are not only small and quite precise, even more precise than high-performance mechanical watches, and the processing difficulty is quite high!

So when Lu Jiadong threw the design drawings to Yang Limin, he plunged into the workshop, using two high-precision boring and milling machines in Guinan factory, and began to train the workers in the workshop, of course, the first to learn was Chen Zihao and Liu Wei, although Wang Sheng and Luo Zhang were higher in the mechanical movement, but in the general operation still taught a lot of things, the only lack is the control and processing of high-precision optical equipment.

In this regard, Lu Jiadong only demonstrated a few times, Chen Zihao and Liu Wei mastered all of them, so Chen Zihao and Liu Wei as the technical seeds, began to train young machine tool workers in the factory in batches, less than a week, there are more than a dozen workers in the military workshop who have mastered the operation of precision machine tools.

In this way, he was busy for nearly a month, and by the end of September, Yang Limin had completed all the design drawings of the fuze, and he had drawn hundreds of pages of design drafts for such a small fuse.

When Lu Jiadong took over Yang Limin's design drawings, he didn't have time to say to him for his hard work, so he hurried to the workshop, summoned Chen Zihao, Liu Wei and more than a dozen other skilled precision machine tool workers, and pointed to the thick stack of design drawings:

"Now that the design drawings have come out, the rest is for us to process!" Lu Jiadong took out a design drawing of the fuse connecting rod and continued:

"I'll process a few parts first, you can take a look, if you don't understand, put it forward as soon as possible!"

As he spoke, Lu Jiadong walked towards the precision machine tool with the design drawing, but before he could take a step, he was stopped by Liu Wei:

"Section Chief Lu!" People who are about the same age as Lu Jiadong basically call Lu Jiadong's real name or Jiadong in private, only Liu Wei always calls Lu Jiadong the position, this is not because of his relationship with Lu Jiadong, but out of respect: "You better let me come first!"

"You?" Lu Jiadong hesitated, but before Lu Jiadong could continue to speak, Liu Wei said with a sincere smile:

"We have been trained by Section Chief Lu for more than a month, even if the design drawings are not in hand, we also remember the size and appearance of these parts, and besides, Section Chief Lu, you have been running day and night for the gun to hang the grenade launcher these days, and the hard work is abnormal, and it is time to rest, so let's do this kind of processing thing!"

"Yes, Jiadong!" As soon as Liu Wei's voice fell, Chen Zihao took over the conversation: "You are so tired these days, you should rest and rest, besides, we are all taught by you, what are you worried about!"

Listening to Chen Zihao and Liu Wei's words, Lu Jiadong couldn't help but hesitate, maybe because he was too anxious, after all, there were only three or four months before the self-defense counterattack. But then I was relieved, the two of them were right, they had been teaching in the workshop for almost a month, and all kinds of precautions had been said countless times.

Thinking of this, Lu Jiadong showed a little relieved smile on his face, and stuffed the drawings into Liu Wei's hand: "Okay, just listen to you, I'm waiting for your good news here!"

Chen Zihao and Liu Wei saw Lu Jiadong let go of them to do it, they were all very happy, and they were all gearing up, just like that, Lu Jiadong moved a chair and sat near the precision machine tool, Liu Wei and Chen Zihao each operated a machine, with the electric switch pressed, the precision machine tool began to rotate, and then a connecting rod, a safety ball, a spring sheet and a firing pin were processed.

Other workers in the workshop also processed the fuze shell, hood, and wind flow air at the same time, and the workers on the assembly line carefully packed the processed parts into the fuze shell, and the bump fuze of a 35mm grenade was completed. The encapsulation machine encapsulates the fuse,

When the excited crowd came to Lu Jiadong with the freshly assembled fuse, the excited laughter and endless words just now came to an abrupt end, because Lu Jiadong, who had been tired for a long time, had fallen asleep on a chair near the precision machine tool
