Siheyuan Great Craftsmen

"Yes, even though only some of the settings have been changed, the boring machine has undergone a tremendous transformation. It is truly a genius idea!" The two of them praised it repeatedly while taking notes in their notebooks.

After the inspection was completed, the two asked someone to turn on the power, started the boring machine, and picked up a rough piece to start processing. Accompanied by a slight machine roar, the two people became more and more impressed by the extraordinary features of this boring machine after the transformation.

After the machining was completed, the boring machine was turned off and the two men picked up the parts and began to measure.

"Excellent work!" they both exclaimed in unison.

"How is it, you two? How does this boring machine perform?"

Although there are experimental data from the steel rolling mill, both Mr. Tang and Zhang Yu are well aware that the data from the steel rolling mill cannot be completely reliable.

"Minister, great leader, the performance of this boring machine is quite outstanding. It has reached the level of similar foreign products, and is even slightly better, reaching the advanced level. Although it is not as good as the original horizontal lathe, it is definitely the best among similar products!"

The two reported truthfully. After hearing these words, Elder Tang and Zhang Yu looked at each other, and could see the surprise in each other's eyes. Elder Tang turned his head and looked at Director Yang and said:

"Xiao Yang, your factory has made great achievements this time! Since the boring machine has successfully passed the acceptance, I hope you can arrange mass production as soon as possible. There are still many factories in our country using old lathes and boring machines. I hope you can continue to work hard and never let down the trust of the organization and the people!"

"Yes, please rest assured, Minister. We will not let down the trust of the organization and the people, and will work hard to complete mass production as soon as possible!"

Upon hearing this, Director Yang was excited and assured Mr. Tang.

Rolling mill

In the technical department, Zhou Tian was training a group of colleagues in the technical department. The content of the training was exactly the design concept, structure and improvements of the boring machine when he designed it.

Many people below were listening attentively and taking notes.

During the training, Zhou Tian not only talked about boring machines, but also some machine tool knowledge related to lathes, grinders, etc. Although the training time was not long, everyone listened very seriously.

This kind of training has been going on for nearly half a month. During this half month, everyone feels that they have gained a lot and the knowledge accumulated far exceeds what they have learned in the past few years.

The more they trained, the more they admired Section Chief Zhou Tian. They found that the knowledge possessed by Section Chief Zhou Tian was as deep and unfathomable as the ocean.

Not only in machine tools, but also in the entire field of mechanical equipment, he has extremely profound attainments.

Sometimes they would discuss privately whether the section chief really only graduated from high school, but such discussions were meaningless because they could not detect the depth of the section chief's knowledge in the fields of mechanics and machine tools.

"Okay, that's all for today's talk about the structure and theory of boring machines. Everyone, go back to your work! get out of class dismissed!"

As Zhou Tian finished his last sentence and was about to leave, he was surrounded by a crowd.

"Chief, I would like to ask, can the lubrication system really change the friction between the gears and thus reduce the noise of the machine tool?"

"Chief, I want to know why linear guides can improve accuracy and smoothness?"

"Section Chief..."

Colleagues from the technical department surrounded Zhou Tian and kept asking questions.

Zhou Tian looked at the eager expressions on everyone's faces and his heart softened. He stopped and began to answer questions patiently. He gave detailed answers to questions ranging from the structure and manufacturing of the guide rails, to the relationship between lubrication and gears, to the impact of various parts in the boring machine structure on the overall structure.

Only when everyone had no more questions did Zhou leave the technical department and return to the office.

Just as he sat down and before he had time to catch his breath, the door was pushed open. Song Lian walked in with a smile on his face. He sat down opposite Zhou Tian carelessly, picked up the tea that Zhou Tian had just poured and drank it all.

This made Zhou Tian's mouth twitch involuntarily. You know, the tea in here is the top-quality tea that he "robbed" from the section chief, and the water used to make the tea is also spiritual spring water.

This was prepared for myself, but I didn't expect that Song Lian would eat it up in one gulp.

"I say, Brother Song, you ruined my tea as soon as you came in. This is simply robbery!"

However, Song Lian rolled his eyes at Zhou Tian without feeling embarrassed at all.

"Xiaotian, given our relationship, you shouldn't be so stingy. But I have to say, your tea seems a little special. I just drank a cup and I felt much better. How about you bring some for Brother Song when you leave?"

As he spoke, he savored the memory for a moment, feeling that his physical fatigue had been alleviated a lot, with a hint of surprise flashing in his eyes.

"Don't give me that! I got this from the section chief with great difficulty. I don't have much myself. You want to rob me? You're dreaming!"

Zhou Tian said unhappily, but he knew very well in his heart that the reason why Song Lian felt comfortable all over was not because of the tea, but the spiritual spring water in it.

"Look at how stingy you are. Brother Song, I'll get you some good tea from my old boss. I promise you've never tasted it before!"

Seeing that Zhou Tian was unwilling, Song Lian did not force him. He showed off a little and then got down to business.

"By the way, I just came back from the military factory, and I heard my colleague from the security department say that you came to see me. Is there anything wrong?"

"Well, Brother Song, I have finished designing the blueprints for the rocket launcher. I was planning to go to the security department to find you, but I didn't expect you to be away, so I had to take it back. Here it is for you!"

As he spoke, Zhou Tian opened the drawer, took out a stack of 107 rocket launcher drawings and handed them to Song Lian.

"Finished, so soon?"

When Song Lian heard that Zhou Tian had actually completed the design of the rocket launcher, he took the drawings in disbelief.

Only when he got the drawings in his hands did he come to his senses.

"So many?"

Song Lian couldn't help but be surprised, because the drawings of the rocket launcher were much more than the drawings of the original Type 56 semi-automatic rifle, more than twice as many as the latter.

"Of course, this is a rocket launcher!"

Hearing Song Lian's surprise, Zhou Tian said helplessly.

"Xiaotian, can you tell Brother Song how powerful this rocket launcher is?"

Looking at the drawings in his hand, Song Lian felt itchy in his heart. Although he was surprised at Zhou Tian's efficiency, he had already become accustomed to the designs of the two firearms, the Type 56 semi-automatic rifle and the AK47 fully automatic rifle.

The reason why he didn't dare to believe it at first was that he didn't believe that Zhou Tianzhen could design a rocket launcher. Now that the drawings are in his hands, even if he doesn't believe it, he can only believe it now.

However, he still had doubts about the rocket launcher in his hand.

Hearing the hint of doubt in Song Lian's tone, Zhou Tian was a little angry, but he could understand it, so he could only say helplessly:

"Well, I'll tell you the specific parameters and features of the rocket launcher I designed. As for whether it's powerful or not, you can judge for yourself!

As he spoke, Zhou Tian began to introduce the advantages, structure and specific parameters of the 107 rocket launcher.

"I call this rocket launcher 107. It is small and light. It is usually towed by trucks, but can also be moved by people or horses. It weighs 385 kilograms in marching mode and 613 kilograms in combat mode. Its maximum range is 8500 meters.

The overall structure of the rocket launcher is relatively simple and light, consisting of 12 launch tubes in three rows and four columns, a rubber-tyred forked slide, a sight, a gun mount, elevation wheels, steering wheels, front and rear rods and other parts.

The transmitting tubes can be removed and used individually, or they can be combined into 1 tube, 2 tubes, 4 tubes, 8 tubes, etc. according to needs.

The directional tube is a 107 mm caliber smoothbore directional tube with a length of 900 mm. All directional tubes are parallel to each other and coaxially installed on the launcher. The gun mount is installed on a forked slide. The elevation wheel on the side can be adjusted within the range of -3° to +57°. The direction wheel on the lower left can be adjusted within a range of 32° left and right.

The rocket weighs 18.8 kg and can be carried by one person. It is particularly suitable for use in mountainous areas, deserts, jungles and rivers. As for its power, do you think it is powerful? "

After the introduction, Zhou Tian asked back.

"Good fellow, I'm not saying anything bad, Xiaotian, but can your rocket launcher really have such a strong firepower coverage?"

After listening to Zhou Tian's introduction, Song Lian couldn't close his mouth for a long time. After a long time, he came to his senses and asked excitedly.

Obviously, whether the rocket launcher is easy to move or carry is not within his consideration. Instead, he is excited about the 12 launch tubes.
