This steam drilling machine was designed by Zhang Feng himself, and even manufactured under Zhang Feng's technical guidance. Pen & Fun & Pavilion www.biquge.info

This drilling machine, not only can process a meter long gun barrel, but also can process a short gun barrel, now the machine tool has been assembled, but also after the preliminary commissioning, Zhang Feng is ready to process a few barrels to try.

Zhao Zuolin had been staying at the Shanghai Machinery Manufacturing Bureau a few days ago, and in the past few days, he has come to the Xiaoqingshan Arsenal to personally watch the installation of this first steam drilling machine.

Zhao Zuolin knew that the Shanghai Machinery Manufacturing Bureau was the baby pimple of the chief soldier, and this steam drilling machine was also the baby pimple in the eyes of the chief soldier.

"Lord Commander, everything is ready for trial processing."

Zhang Feng was ready to take a look at the processing situation in person, so he waved his hand, "Test processing immediately!" ”

The barrel blanks had been prepared for a long time, all made of steel produced by the Shanghai Iron and Steel Works, and this barrel was certainly better than the previous fine iron barrels.

In addition, the drill bit has long been prepared, and the Shanghai Iron and Steel Plant has made several furnaces of "alloy steel", which are mainly used to make various tools, knives and so on.

Zhang Feng also knows that this so-called "alloy steel" is far from reaching the standard of modern alloy steel, but in the Ming Dynasty, in this era, it is definitely a big lead, used to make all kinds of processing tools, such as turning tools, drills, etc.

Everything is ready, only the east wind is owed.

Now, Dongfeng also has it, and with an order, processing begins immediately, and the first thing to process is a short barrel.

The steam engine started, the drilling machine also began to work under the drive of the steam engine, the drill bit slowly drilled into the barrel blank, the iron filings were drilled out little by little, and the cooling water was even slightly steaming.

Minute by minute, only the sound of the steam engine and the drilling machine working, no one spoke, and all eyes were focused on the barrel being processed.

Rough machining, finishing, processing rifling, etc., one process at a time, the first barrel was finally processed, Zhao Zuolin personally removed the barrel and gave it to Zhang Feng in person.

"Lord Commander, take a look at the first barrel we made."

Zhang Feng took a closer look with his professional eyes, and then said with satisfaction: "Yes, very good, Lao Zhao, it seems that this steam drilling machine is very successful." ”

Zhao Zuolin also took the barrel and looked at it carefully, after looking at it like this, Zhao Zuolin also nodded and said: "Lord Commander, it is worthy of the barrel processed by the steam drilling machine, and the quality is much better than our handmade barrel." ”

The first barrel was processed, then the second and third barrels were processed, not only the short barrels were processed, but also the long barrels were processed, and the quality of each processed barrel was good, which fully met Zhang Feng's original expectations.

The performance of this steam drilling machine is also good, the processing is stable, the only drawback is that the noise is a little big, because it is steam driven, the sound of the steam engine and the sound of the machine tool together, there is a little deafening feeling.

However, it is okay to be a little louder, and in general, the design and manufacture of this steam drilling machine are relatively successful, and it is estimated that many units will be manufactured in the future.

A few days later, the shooting range of the Xiaoqingshan barracks.

Wang Chaoyong got a few new guns, which were a little different from the previous flintlock muskets, which were of course improved rifled flintlock muskets.

These guns are prototypes that have just been manufactured, and they are ready for test firing today.

The original test firing of the smoothbore flintlock musket was carried out by Wang Chaoyong, and this time, it was Wang Chaoyong himself who handled the knife, and when he heard that there was a new gun, Wang Chaoyong volunteered, and a major general and division commander did not hesitate to "deign" to do this kind of thing.

"Commander, this new gun looks good." Holding the new gun, Wang Chaoyong looked happy.

Zhang Feng said: "Give it a try and see the effect." ”

Wang Chaoyong nodded, while loading, he looked at the targets in the distance, and said worriedly: "Lord Commander, the gun target is placed so far, it's too far!" ”

There are three kinds of targets, the nearest is 50 meters, the farther is 100 meters, and the farthest is 200 meters, which really looks a little far.

If it is a smoothbore flintlock musket, it is almost impossible to hit a target 200 meters away, and a target of 100 meters also depends on a bit of luck, but this is a rifled gun, Zhang Feng wanted to try to see if he could hit a target 200 meters away.

Zhang Feng said: "It's not far away, just try it and you'll know, first hit the 50-meter target, then the 100-meter target, and finally the 200-meter target." ”

Wang Chaoyong's action of charging is very skillful, although it is a rifled gun, but because there is no smokeless gunpowder, the use is still black powder, or paper shell bullets, but the warhead has changed.

In the past, it was a lead-cast warhead, because the previous barrel was hand-made, and the diameter of the barrel was a little different, in order to prevent jamming, there was a relatively large gap between the lead-cast warhead and the barrel, which caused a loss of energy, and the power naturally decreased.

Now it is a pointed steel warhead, made of steel, processed with a lathe, and the size of each bullet is uniform, because the barrel is also machined, the diameter error of the barrel can be controlled in a relatively small range, and the gap between the bullet and the barrel can be relatively small.

In this way, the power of the warhead is greater, because there is rifling, the warhead rotates at high speed and flies out of the muzzle, the range is also longer, and the power is also greater.

When Wang Chaoyong saw these changes, his curiosity also rose, he quickly loaded the bullet, and then took the gun and aimed at a target fifty meters away.

Wang Chaoyong wanted to see what was different.

Three points and one line, aiming, and then, Wang Chaoyong pulled the trigger, and there was a "bang" of gunshot, and a thick smoke came out of the muzzle, which was the disadvantage of black powder, and the smoke was relatively large.

Wang Chaoyong has good eyesight, he has already seen that he is hitting the bull's-eye, and he can't help but feel proud for a while, and said to a guard next to him: "Xiao Li, go and carry the gun target." ”

"Yes!"

The guard Xiao Li trotted all the way and carried the gun target over, and everyone came up one after another, and everyone felt slightly shocked, because there was only a small hole on the gun target that was less than the thickness of a finger, and the small hole was smooth and flat around the hole, which was completely different from the hole made by the previous musket.

In the past, if the musket hit a 50-meter target, it would open a large hole the size of half a fist, and the area around the big hole was not even and smooth, but a little damaged.

"This hole is so small!"

"With such a small hole, is it not as powerful as a gun?"

“…….”

Everyone gossiped and argued for a while, Zhang Feng smiled and said: "The power is not good, just wait and try it." ”

The hole is so small, and the hole is so smooth and smooth, this is not a small power, on the contrary, it means that it is powerful and penetrating.

In the past, the lead bullet must not have such power, the last time in Tianjin Wei, the thick shield of the Manchu Qing Dynasty formed a wall, and the lead bullet penetrated such a thick shield relatively reluctantly, so that the Manchu Tartars rushed to the city, and thousands of Manchu archers threw at the city wall, causing a lot of casualties to themselves.

If it were the current rifled guns, the thick shields of the Manchu Qing would not be able to block it at all, the archers would not be able to get close at all, and there would not be so many casualties.

Although Wang Chaoyong is good, his understanding of modern firearms is naturally not as good as Zhang Feng's, so Wang Chaoyong couldn't help but be a little worried, and asked: "Chief soldier, is this not powerful, can such a small gun hole kill people." ”

Zhang Feng said: "How about the power, wait a minute, let's know, then hit a 100-meter target, try the shooting accuracy first." ”

The 100-meter target is already relatively far, and the previous smoothbore guns, because of the relatively poor shooting accuracy, had to hit a target 100 meters away.

This time it was another 100-meter target, and many people muttered in their hearts whether this could be hit or not.
