On that day, King Yong came to see Chongzhen excitedly and reported that the lathe was successfully trial-making, and he pestered Chongzhen to see the first lathe he led to trial-making.

Since King Yong and King Ding personally participated in the production of the dual-stage blower, especially after witnessing the hot air balloon rising into the sky, young people have become interested in various technologies driven by curiosity. Since then, the princes have firmly believed in Chongzhen's description of "flying in the sky and swimming under the sea".

After arriving in Nanjing, Chongzhen issued an edict, arranging the two princes to be responsible for a military project, Yong Wang served as the "Ming Ming Machine Tool Manufacturing Commander" and Ding Wang served as the "Ming Ming Steelmaking Commander". Of course, this is exactly the same as the commander-in-chief of the later leaders. In fact, Wang Chengen was responsible, but with the sign of the prince, the green light was given in all aspects, which made him much more efficient.

Chongzhen first selected some smart students from the sons of Nanjing, and followed the two princes and started learning while learning. Fang Yizhi selected craftsmen who were skilled in the machinery group and selected those who were skilled in smelting into the steelmaking group. Of course, all the plans and designs were still from Wang Chengen, and the craftsmen were naturally the implementers. The princes were the participants, supervisors, learners and recorders. What Chongzhen values ​​was that these young people would be the new force in future technology promotion.

The first step is to make lathes and boring machines. With lathes and boring machines, gun making and cannon making are not only efficient, but also have good accuracy. It can be said that lathes and boring machines are the cornerstones of the military industry.

Yongwang gathered a member of the machine tool group together, and then Wang Chengen began to tell everyone how to make a lathe. Wang Chengen first praised China's suspected machine tools and introduced the original grinding machine used in the gem industry. China's gem industry had already used the original version of the grinding machine, using the foot-pedal method to rotate the iron plate, and sand and water were used to cut jade. The so-called sand is abrasive particles, such as silica, silicon carbide, etc., and the silicon dioxide silicon carbide craftsmen don't understand, but the young people in charge of the recording should understand that the hardness of the gem is hard enough, but the harder silicon carbide can be used to cut gems.

The foundation of machine tools is the lathe, which is the source of thousands of sources. The first generation of lathes is the simplest, which is a rotating iron plate and a moving knife holder, plus a tail holder. Under the guidance of Wang Chengen, the first lathe was finally out of the cage. King Yong came to report to Chongzhen happily that the lathe team he led had achieved major results. He was just like offering treasures and asked the emperor to go to inspect in person.

Chongzhen was also very curious about what the lathe made by Wang Chengen looked like, and excitedly ran to observe the creation and invention.

I came to the machine tool set with a close look. When I looked closer, I saw that the so-called lathe was extremely simple. I saw a wooden table, a copper seat was installed on the left side of the table, a shaft was installed on the left side of the shaft, a wheel with a suspected pulley with a bull tendon strip, an iron plate with a drilled hole was installed on the right side of the shaft, and a thing that looked like a tail frame was installed on the right side of the table. Two iron rods were installed on the front of the table, and a rack with a suspected knife frame was installed on these two iron rods. The rack could slide left and right on the two iron rods. There was a foot pedal under the table, which was obviously used to drive the spindle of the lathe at first glance.

After the emperor arrived, two craftsmen began to demonstrate the processing process of the lathe. One craftsman installed an iron rod blank on the iron plate and pressed the other end with a tail frame. The other began to step on his feet. The main shaft of the simple lathe began to rotate, driving the iron rod workpiece to rotate. The craftsman in charge of the operation approached the iron rod, and then made a squeak. The cookie was under the cart with a layer of iron filings. The operation craftsman carefully pushed the knife holder to the right, so he cut a circle of iron filings on the right side of the circle that the iron rod had just cut. He carefully pushed the right slowly and drove it down one by one, which was the first time he entered the drill.

Although the wooden platform was very strong, it still creaked and shook when turning. Chongzhen's throat was hanging, afraid that the platform would fall apart. After half an hour, he finally finished his first drill. An iron rod about 400 mm long and the thickness of a small arm was only a little bit. It took him half an hour to get a round of the car. The stepping made Chongzhen sweat in his heart. When the second lap of the car changed to another person, he stepped on the pedal, and this time he was faster. After all, the iron rod was turned into a first lap and the roundness increased. After about twenty minutes, the second lap was finished, and then the rough car was fine. When the car finished, it took more than two hours.

After removing the processed iron rod, Yongwang did not wait for the iron rod to cool completely, and wrapped the shiny iron rod with cloth and handed it to Chongzhen for inspection. Chongzhen looked at the rough iron rod from a distance, looking at the rough iron rod from a distance, and compared it with beautiful metal parts from later generations, which was really disappointing. However, when he thought that it was rare that King Yong was so concerned, he praised a few good words. After hearing the encouragement, he was very encouraged, and the children of the honor and relatives next to him were also honored.

When he returned to the palace, Chongzhen quickly called Wang Chengen and said:

"I said this lathe is too primitive. Just because of this thing, I will fall apart after a few strokes of the car, let alone build guns and cannons. Do you think so?"

When Wang Chengen saw Chongzhen's urgent appearance, he laughed and said:

"My Master, you don't have to worry! This is the first generation of lathes. With the first generation, there can be the second generation, the third generation, and even the n generation. The first generation of lathes is the second generation of lathe spindle, and the second generation of lathes is the third generation of lathe spindle. The accuracy of lathes is little by little. Then, put on a full metal lathe, then put on the spindle box, and match the gears. After fitting the gears, you can put on the ball screw. Then you can make threads and the like. In short, don't worry, your elders! I think Yongwang and these young people are very energetic. In the future, they have experience, whether it is a lathe or a boring machine, they will get faster and faster."

Chongzhen was skeptical and said, "Is that true? Of course it would be great if this is the case!"

Wang Chengen smiled and said, "There is a long way to go in terms of machine tools and machine tools! Just to make standard flat panels, you need to use manual grinding to make three flat panels at the same time. The three pieces are grinding and grinding together. First, you carefully scrape the protruding parts with a steel scraper, then grinding them with grinding, and finally make a very accurate plane. The purpose of making three standard flat panels is to use three plates to grind and inspect each other, find out the unevenness of one convex and one concave, and then grinding the protruding parts. Then grinding and grinding them again... This cycle is repeated n times until the surfaces of these three plates are infinitely close to the plane."

The father of Chongzhen's later generations was a Class 6 fitter with good skills. He knew that this grinding plane was a technical job that really tests the grinder's ability, and asked now:

"In this era, where can I find a level 8 fitter to polish standard flat panels for you?"

Wang Chengen said: "Your Majesty, you don't know the truth about this. The craftsmen of the Ming Dynasty relied on hand to make their meals, and they were all skilled craftsmen. Why? There is no such machine or machine. So it's easy to find a few craftsmen who are equivalent to the eighth-level fitters in the future. Wu Qingfeng brought from Beijing from Beijing is a natural good craftsmanship, and the craftsmen in Nanjing are also good. I'm arranging Wu Qingfeng to bring three craftsmen to grind the standard board. With this standard board as a testing benchmark table, you can use this standard plane to check the processing parts of the car at any time, which improves the processing accuracy of the car processing. In addition, there are vernier calipers, micrometers, plug gauges, measuring blocks, etc. These measuring tools must be made one by one. It takes time to achieve standardization and interchangeability, but this time will not be long. Let's fight for a year! Let's see if the group of Tong Sheng and Juren who served in the military can be in place as soon as possible, and you must also see

How long after the position is to be able to get started? With talent, the whole process is much faster. In history, it was not until 1794 that Mozley invented the automatic lathe box, and it was not until 1797 that Mozley's first all-metal lathe was produced. It was not until the beginning of the 19th century that the lathe was still driven by foot, and it was not until 1810 that Mozley's steam-driven lathe was launched. It took 20 years for the development of the lathe before and after the lathe to evolve into the basic style of later lathes. My Emperor, my plan was to complete the thread lathe within one year and try to produce a steam-powered lathe within two years. This was the speed of the Great Leap Forward. Rome was not built in one day, and later generations always said that leap forward. We have developed over 150 years, and the emperor should be satisfied!”

Chongzhen nodded and said, "Time doesn't wait for anyone. According to the information, the Qing soldiers have also developed a fire-pulling grenade. The Qing soldiers and Li Zicheng may soon start war. Li Zicheng's combat power is still not as good as that of the Tartars."

"Didn't Li Zicheng gather 200,000 troops in Shanhaiguan and the Great Wall? The Qing soldiers had to prepare for at least half a year. After half a year, our infantry artillery and mortars should have been offline. The eliminated crossbow-type thunderbolt thrower can be sold to Li Zicheng."

When Chongzhen heard that mortars and infantry cannons could be installed, he breathed a sigh of relief. He thought that as long as the time for peaceful construction was guaranteed, infantry cannons and mortars were equipped, there were guns and cannons at that time, and the new army had almost finished training. At that time, even if the Tatars invaded the south, they would definitely not be able to go.

Chongzhen was getting more and more arrogant and asked immediately:

"When can those big caliber howitzers and the like be tested?"

When Wang Chengen saw Chongzhen eating in the bowl and the pot, he couldn't help but smile:

"Your Majesty, our plan is to focus on improving the field capabilities of infantry in the first year, especially improving the field capabilities of infantry against cavalry, so we did not consider developing heavy artillery in the first year. Besides, have we discussed Yuan Chonghuan's "Based on the city and used cannons" tactics before! Not to mention that Yuan Chonghuan's tactics can only be used as fortress defense and has no offensive ability. It is pure bragging to rely on this tactics for five years to pacify Liao. In fact, heavy and stupid cannons like the red-clothed cannons, which are heavy and stupid without shooting accuracy, are only useful when siegeing cities, and their functions in field battles are far less than those of mortars and infantry cannons."

Chongzhen's complex of heavy artillery may be thanks to Yuan Chonghuan. In later generations, Chongzhen was also a military fan, so he naturally knew that before the cannon barrels were bored, the cannon body was cast, heavy and stupid, and there was no retracting device. The maneuver was extremely inconvenient, and the speed of the cannon was also very slow, which means it was suitable to be installed in a fortress. To use heavy artillery to follow the army, it would greatly reduce the maneuver power of the army, which was really not worth the loss.

Chongzhen still didn't give up and asked:

"How about the machine gun if you can't make a heavy artillery?"

"It should be possible to make a Gatling machine gun within three months, but if steelmaking cannot keep up, it will be useless to make such a machine gun. High-fire rate will cause the barrel to overheat quickly. Without good steel, the barrel of the high-fire rate will be scrapped in a few minutes. It's better to wait until the open furnace steelmaking of Dingwang is successful!"
