4/18/77.

Guan Fei finished his morning troop trip and returned to the brigade headquarters. This morning he mainly inspected the fortification construction on the northern and southern fronts, and the results made him very satisfied.

The northern route is just that, the mountain river is already narrow, and after digging a tunnel on the mountainside by blasting, it is stable enough. Now it has been re-solidified with reinforced concrete, with the addition of more shooting holes, and the defense system has been improved.

Even if the Wei Dingjun immediately dispatched a division to attack head-on, the northern front would be able to make them meet and return home.

Previously, the southern front was very difficult to defend because of the large frontal width and many defensive points.

However, after the reinforcement of multiple reinforced concrete, a number of new permanent fortifications were built, and the positions connecting the various hills were also greatly strengthened. And having a sufficiently stable position, the 291st Brigade began to slowly push the defensive line forward, and established a new defensive position on the river beach and five or six hills in the middle of the hillside, which also used reinforced concrete fortifications. Communication trenches, hiding holes, ammunition depots, fresh water storage points, field hospitals, and so on are all available.

In addition to the heavy firepower positions at the commanding heights of the rear hills, the defensive thickness of the southern front has been greatly enhanced, and even if the enemy relies on the superiority of troops, it is impossible to achieve a strategic attempt to break through at all and collapse the entire front.

Moreover, the front of the southern front is wide, and it is also relatively speaking.

The total width of the river beach and gently sloping hills on the southern line is only about three to five kilometers, and the flat land that can be used for the deployment of troops is only a few hundred meters. With a large number of permanent fortifications, the staggered firing points of the Ming and Dark Forts, and the seizure of several major commanding heights, the enemy did not have enough space even if he wanted to make a detour.

After months of hard work, Guan Fei can finally announce loudly: 291 Brigade is invincible!

The husband is a general, and he does not think about victory and loses first!

Since opening up the 291 Brigade Defense Area, he has always been tirelessly considering how not to suffer defeat and prevent the enemy from entering. To this end, he used a lot of brains, with the help of the biological auxiliary brain, repeatedly carried out virtual deductions, constantly revised the defense system, and personally supervised the construction of the defense line.

Only today can he breathe a long sigh of relief.

That's it for the time being, wait another two years, and after the strength is more sufficient, it's time to close the Menggu defense line. At that time, the entire 291 Brigade was one piece, even if the enemy attacked heavily, he was confident that the opponent would stop under the fortified city and not advance an inch of land!

The security situation before the 291st Brigade relied on domestic guarantees. But from today, the future of the 291 Brigade can finally be defended by its own strength no longer under the pretense of external forces!

As soon as the defense zone is stabilized, then some work that has been delayed can also be carried out.

After Guan Fei completed today's inspection, he was very high-natured, and everyone he met along the way was smiling. As long as a warrior saluted him, he would always return the salute meticulously, and would talk and laugh with the other party.

"Brigadier Commander, you seem to be happy today?" The guard Li Qing made a meal and handed it over, and when he saw him smiling, he also said happily.

"Yes, after watching it today, I finally feel at ease with our defense area, how can I be unhappy." Guan Fei happily took the meal and ate the pickles and leftovers in a big gulp.

"We have you, even if the enemy comes, we are not afraid." Xiao Li patted his ass.

"Hahahaha!"

Guan Fei put down the bowl and laughed loudly, almost choking, tears appeared in his eyes, and the tip of the chopsticks pointed at Xiao Li: "You, you, if I want to have such a god, I would have defeated all the enemies a long time ago, and I would shrink into this small ravine?" The sycophants didn't shoot like that. ”

"Aren't you a hidden dragon in the abyss? In the past, the People's Army was blindly commanded, and you had no right to speak, so you always suffered defeats. But now that you finally have the power to command the troops independently, don't you think our situation is very different? What is this called, this is called the dragon returning to the sea, and the dragon will eventually fly in the sky! "Xiao Li's sycophants are like a tide.

Guan Fei shook his head with a smile, took a few bites of rice, and didn't answer.

He can acquiesce to the following views on the BJP, but he himself will not blame. This is a matter of organizing principle. If he himself ignores the organizational principles, then the collectives he will build up in the future will have no organizational principles to speak of.

"Xiao Li, you go and ask Lao Zhang if they are ready, the technical school will officially start running in the afternoon, and I will also go over. In addition, I will inform the school and ask Mr. Tang to come over as well. Guan Fei didn't want Xiao Li to chew on the root of his tongue anymore, so he simply sent him out to run errands.

"Yes!" When it came to business, Xiao Li no longer had a hippie smile, stood up and saluted solemnly, and ran out quickly.

Guan Fei stopped his chopsticks and conducted a comprehensive analysis of the current state of the 291st Brigade's hearts and minds according to various phenomena in the memory of the biological auxiliary brain.

The current situation of the 291st Brigade can be described in one word, that is, people's hearts are upward.

The first step in solving the problem of eating is to have a means of communication with the outside world, so that the soldiers and intellectuals no longer have the feeling of being isolated from the outside world, and the whole people's hearts will soon be completely stabilized. The operation of the servicemen's service club and the bank, as well as the distribution of allowances, allowed the soldiers to truly link their interests with the 291 Brigade.

Whether it is an allowance, a salary, or a high school diploma, this represents the reward that people get after their labor, which is very different from pure enthusiasm and faith.

Faith and enthusiasm will eventually fade, but interests will not, but will play an increasingly important role in people's hearts over time—it may be positive or negative.

In the past, soldiers might give up and leave, but with allowances, with military seniority and seniority calculations, the cost of giving up would be so great that they would think twice and think twice very seriously. After that, supplemented by the continuous bright future of the 291st Brigade, the possibility of the fighters breaking away from this collective tends to be infinitely smaller.

Only when people live do they need faith, and this life is the continuous desire and pursuit of material life, which accompanies people throughout their lives.

What Guan Fei did was to continuously strengthen everyone's firmness in their beliefs, while giving them material rewards and promising a better tomorrow, so that they could feel that their pursuit was sacred, correct, and closely related to their future, so as to strengthen their faith in turn.

In this way, while the defense line is stable, the defense line of people's hearts is also stable......

"Brigadier Guan, you're back!"

As he was thinking, there was a loud commotion outside the door, and a group of meteors strode towards his place, shouting loudly from afar.

It's Mr. Tang, and they.

When Guan Fei saw them, he knew that he might not be able to eat next, so he hurriedly took a few bites, chewed a few times, swallowed his stomach, and put the dishes and chopsticks aside. He stood up, strode out, held Teacher Tang's outstretched hand, and said with a smile: "I asked Xiao Li to see if you were ready, but I didn't expect you to come over." ”

"Of course we have to come over, we can still sit still when we hear that you are back!" Teacher Tang laughed, and the other teachers also laughed and said nothing, and bowed their jaws in agreement.

After Guan Fei took out the middle and high school textbooks, the attitude of the school teachers towards him suddenly changed greatly.

Before, everyone only thought that he was the head of the 291st Brigade, and although they were happy to liberate them from the countryside, everyone was not a person after all, and they thought that he was a relatively successful and excellent stupid soldier. So I always have a faint sense of alienation from him, and I am very polite and respectful when we meet, but I am never affectionate.

But as soon as the textbook came out, everyone realized how deep Guan Fei's knowledge was. In the words of President An: You think you are high-level intellectuals, but when you compare them with Brigadier Guan, you know who the real high-level intellectuals are!

Almost in a blink of an eye, the teachers let go of their sense of superiority over Guan Fei, made friends sincerely, and often asked him for advice on some questions.

In the beginning, the purpose of asking for advice was to test him, but soon everyone knew that he was really knowledgeable, and then turned to real advice.

This kind of consultation reached a new level after Guan Fei asked them how to modernize the C616 universal lathe.

C616 lathe is a general lathe produced by Jinan No. 1 lathe factory, due to reasonable design and high processing accuracy, it soon swept the country and was vigorously promoted, becoming the preferred equipment for general machinery factories and general equipment production lines in factories and mines, with a great amount of ownership.

But no matter how good the C616 is, it is also an early manual lathe.

Internationally, since the sixties, research on the combination of data control and lathes has been carried out. By the seventies, CNC lathes became more and more mature and began to develop rapidly. Compared with traditional manual lathes, CNC lathe workers have low labor intensity, extremely high work efficiency, and the machining accuracy is much higher than that of manual lathes, which rely heavily on workers' skill proficiency.

At this time, C616 seems to be a little behind the times.

However, C616 has a large number of holdings in China after all, and in terms of domestic capabilities, it is unrealistic to promote CNC lathes in large quantities. Therefore, in order to improve labor productivity and improve machining accuracy, research on the modernization of C616 has been carried out in China.

The topic proposed by Guan Fei happened to touch the G-spot of all teachers, especially university science and engineering teachers, and set off a research peak in the teacher group to transform the C616 general lathe.

In fact, in this era, in addition to CNC machine tools, there is also an automated machine tool that is also favored.

Automatic lathes and CNC machine tools, in form, are the same thing, both drive the lathe to work through digital control. But in essence, they are very different.

The realization of automatic lathes is to let workers first manually process the workpiece on the lathe and collect action data through various sensing devices. Then, according to these data, the same model of automatic lathe can act autonomously according to the predetermined stroke.

This is different from the CNC lathe's data-based, pre-modeled by software, and then processed by computer-controlled processing.

In terms of advancement, CNC lathes are far better than automatic lathes, and the development potential is much greater. However, the difficulty of automatic lathes is low, so there are many followers, and at present, its popularity even exceeds that of CNC lathes, and is known as the next generation of lathes.

Guan Fei asked these teachers to try to modernize C616, without putting forward preconditions, he just wanted to see if these teachers had any new ideas under the current trend of thought.

But the results disappointed him.

Although these teachers, especially the engineering teachers in colleges and universities, are very attentive and have put a lot of thought into it, most of their improvements are made in some details.

For example, the positioning handle has been improved, the feeding system has been redesigned, and hydraulic fixtures have been installed. Some of these improvements are also remarkable, but in general, even automatic lathes are not counted, can only be said to be local detail improvements, focusing on reducing the labor burden of workers, improving labor efficiency, and improving machining accuracy.

If you look at it from the perspective of this era in China, the improvement design of these teachers is already good, but in terms of the improvements made by later generations based on C616, it can almost be evaluated as a dojo in a snail shell, and it has not escaped the original shackles of the machine tool.

Guan Fei looked at all their designs and commented on them one by one, and then took out the improvement drawings he had prepared: the specific transformation blueprint for transforming the C616 into an economical CNC lathe.

As soon as this renovation material was thrown out, it caused a sensation.

The improvements made by the teachers are to make up for the original shortcomings of the modified machine tools. Guan Fei's transformation is too bold, and he has carried out a wide range of transformations to the C616's longitudinal and horizontal feed system, power components, guide rails, and tool holders.

To put it mildly, Guan Fei has redesigned a new machine tool on the basis of retaining the original lathe bed!

After a brief silence, the teachers began to fight back.

The teacher of electronics and electrical engineering first questioned the automatic control system, believing that the design of this system requires very deep knowledge of Ic circuits and programming, and at the same time, it is also extremely familiar with the knowledge of motors and machinery. Guan Fei's design is very good, but to complete such a large-scale transformation, only a special mechanical research institute can achieve it, and even a mechanical research institute may not be able to do it, and it is necessary to invite experts in automation to participate and assist in completing it.

As we all know, limited by the low level of integrated circuits, the level of automation in China is very low. Even if there are experts with considerable automation attainments, I am afraid that they are not proficient enough in machinery, and it is not a problem to piece together a so-called CNC lathe, but whether the improvement is reasonable, whether the accuracy is guaranteed, and whether it can operate normally for a long time, there are great doubts.

Their evaluation is: This transformation plan is too ambitious, and the lack of feasibility is not something that the 291st Brigade can complete independently!

The teachers in mechanical design are also not optimistic about this transformation plan, but judging from the design of the mechanical part that Guan Fei took out, it can be called flawless. They were very conflicted, on the one hand, they were quite interested in the subject, and if it succeeded, it would be a great gain for them, and they were extremely hopeful that the renovation plan would succeed. On the other hand, a considerable degree of skepticism has been expressed about its feasibility.

In the midst of this noise, Guan Feili ignored public opinion and forcibly got on the horse, and the C616 renovation project began.

Mr. Tang and others are members of the renovation engineering team.

Today, under the leadership of Guan Fei, they will overcome the first difficulty: the research and development of the four-position automatic rotary turret.
