I, the patron saint of the frontier of the Tang Dynasty, was forced to rebel

Chapter 113 Gun Processing
As long as you have enough points, you can even directly purchase advanced weapons and equipment, and it will not be a problem to dominate the current world.

It's a pity that I took a look at the tank, and it was from World War II, and the price was as high as 666666666!

The numbers seem to be endless and impossible to count.

"Is it not intended for me to buy it at all?"

Qin Mu was speechless. This was obviously just for show, and he didn't even think about selling it.

With the speed of the current task and the analysis of rewards, it will take several lifetimes to afford it!

In the search box in the upper right corner, "gunsmithing" was entered.

The mall opened quickly, and there were a large number of new firearms, ranging from 10,000 points to [-]+ points.

Qin Mu pondered for a moment, and the current technology of the Academy of Sciences is capable of producing rifled guns.

Rear-loading guns appeared in the [-]th century, and fixed ammunition appeared in the [-]th century.

Rifled firearms became mainstream, and rifles with buttstocks and long barrels were usually used by infantry as rifled rifles.

Therefore, he needs to increase the firing speed and shooting distance as much as possible while the progress of gunpowder improvement is slow.

Then there is only one way, to strengthen the barrel and describe the rifling!

Even in the twentieth century, there were only four methods of rifling, not to say that there were no other technologies, but the four most widely used in mass production.

Wire drawing method, wire extrusion method, electrolysis method and precision forging method.

The first wire drawing method is to use a special broach, but the efficiency is low, and it is only suitable for small batch production and rest for rifling defects.

The second line extrusion method uses the extrusion head to forcibly pass through the smooth bore to cause plastic deformation of the metal to form rifling. This method is easy to operate and has high efficiency.

Moreover, this method can also improve the life of the barrel as much as possible.

It is not the precision parts that wear out the most in firearms, but the barrel!

Unfortunately, this requires strong basic material research and development capabilities, as well as sophisticated processing equipment.

The third electrolysis method uses the gun barrel as the anode and the mandrel with convex and concave as the cathode. In the sodium chloride solution, the metal on the negative line of the surface of the smooth bore is analyzed by electrolysis to form rifling. Generally, large and medium-caliber gun barrels Rifling is processed by this method.

Don't think about it, there is no electricity, and the electrolysis method is still used.
The fourth precision forging method, which is quite special, is carried out on a special gun barrel precision forging machine.

It is also a more advanced method in the [-]th century, but it requires a higher technical level!
There is no need to think about this, or it is completely impossible to dream of!

Qin Mu laughed at himself, the only one most likely to be realized by the four technologies is the first one.

Therefore, I purchased the technical data of the wire drawing method, and also purchased the precision manufacturing technology.

A total of [-] points were spent, and the remaining [-] points
Empty at once!
"Oh, the points come and go in a hurry."

After a while, the technical information was extracted from the system warehouse.

After opening the first page and not reading much, he was stunned.
As a military staff officer, he definitely knows war, firearms, and combat equipment very well.

However, the production process and equipment are not understood at all.

According to the information, the broach needs to be made of "high-speed steel"!
Not to mention the processing equipment, the high-speed steel, commonly known as "white steel", is currently impossible to realize.

High-speed steel is a tool steel with high hardness, high wear resistance and high heat resistance, also known as high-speed tool steel or front steel, commonly known as white steel.

Moreover, high-speed steel was created in 1898 by FW Taylor and M. White of the United States.

It is mainly used to manufacture complex thin blades and impact-resistant metal cutting tools, as well as high-temperature bearings and cold extrusion dies.

Hardness and sharpness are extremely high!

"Since hardness and sharpness are required, why not try it with diamonds?"

He somehow thought of diamonds. Before rebirth, man-made diamonds were mostly used in industrial manufacturing, and they could also be used as various cutting heads.

Thinking of this, I couldn't help being happy for a while.

Opened the mall again and searched for diamonds.

Not to mention, there is everything in the mall, and I immediately found all kinds of diamonds, all of which are very expensive!
The cheapest one is more than [-] points, and it is calculated per carat
He is not in a hurry to buy it, mainly to see if it can be used.

In the end, I closed the system interface in disappointment.

Diamond turning tools are only suitable for processing aluminum, aluminum alloys, etc. Steel cannot be cut at all.

"King Xian, Dean Chai wants to see you, do you want to see me?"

"Chai Xinghuai!"

He remembered very clearly that this person was the person in charge of the research and development of ordnance equipment and one of the most important people in the Academy of Sciences.

"See, bring him here immediately."

The servant stood at the door in surprise, hearing King Xian's tone as if he was in a hurry?
He walked to the outer hall, "Master Chai, the King Xian promised, let me take you there."

"accepted?"

Chai Xinghuai was stunned for a while, and he came to the palace several times by himself, but he hardly saw anyone.

The reason was not that Qin Mu was really busy, but that he found various excuses to deliberately avoid it.

Because, every time he comes, it is for scientific research funds.
No way, there are more than [-] affiliated research institutes, and money is needed everywhere, and experiments are the most expensive place.

"Really see me?"

"Really, Lord Chai comes with me."

The servant couldn't help feeling amused, and walked side by side with Chai Xinghuai to the door of King Xian's study.

Bang bang bang!
Hearing the knock on the door, Qin Mu raised his head: "Don't be too polite, just come in."

Chai Xinghuai became more and more suspicious, not knowing what the King Xian was up to.

"Your Majesty, Your Majesty."

"You don't need to be too polite, I happen to have something urgent with you, so you should take a look at this first."

Qin Mu explained all the information about broaching and rifling processing.

Chai Xinghuai frowned, as if not surprised.

"Actually, the three encircling lines, oh, are the rifling lines that King Xian said. We have been studying them for a long time, but we haven't completed the theoretical knowledge. I didn't expect King Xian to have made a detailed plan."

"You've been working on this for a long time?"

"That's right, the rifling is finished inside the barrel, which can increase the bullet's firing speed and shooting distance. According to our research, it is the 'rotational force' that increases kinetic energy!"

Speaking of this, Chai Xinghuai looked extremely serious, and he has always been cautious about scientific research.

"Also, if the rifling can be realized, it can also increase the accuracy of the gun!"

Needless to say, Qin Mu naturally understood.

It can be said that the rifling is the soul of the gun
"Then, how do you plan to describe it?"

"The original plan was to use casting technology to divide the gun barrel into two halves and complete the carvings separately, and then use high-temperature welding technology to complete it, and it is being carefully crafted."

"No, this method can be said to be a waste product. Not to mention that it will cause the barrel to blow up seriously, and the rifling is not accurate enough to be used at all."

Hearing this, Chai Xinghuai nodded.

"This is the reason why our theory is terminated, but now that we have the technical information of King Xian, it shouldn't be too difficult."
