…………

This hydraulic milling machine is a very primitive hydraulic milling machine that Zhang Qingfeng has polished by hand in the past few months.

The main power of this milling machine is the shaft transmission of the water wheel.

The shaft transmits the power of water to the factory building. Using the combination of large and small gears and the operation of the belt, Zhang Qingfeng can make the shaft of the milling machine rotate at most [-] revolutions per minute. This speed is very low, but there is no problem in processing some simple parts.

Due to the simple mechanical structure, serious waste of power, and insufficient precision, the precision of parts that can be processed is limited.

But even so, it is much faster than manual sanding.

It took Zhang Qingfeng three or four months to make this milling machine, from August last year to February this year.

Fortunately, with this milling machine, Zhang Qingfeng can use it to manufacture more sophisticated machines.

The first milling machine was too primitive and the precision was too poor, but he was able to help Zhang Qingfeng process rough blanks, saving a lot of time.

If it took Zhang Qingfeng three or four months to manufacture the most primitive milling machine, it would take even less time to use this milling machine to manufacture a more precise milling machine.

Today, what Zhang Qingfeng wants to process is the last few parts of the new milling machine. After these parts are processed, he can assemble a milling machine with complex structure and relatively precision.

With a relatively precise milling machine, it is much easier to manufacture other machine tools.

Although Zhang Qingfeng has several machine rooms here, the most sophisticated one is the original milling machine. In the other machine rooms, there is a grinder, which is called a grinder, or rather the most primitive grinder, with only one set of shafts. Speed ​​change device and ball type grinder for sharpening with whetstone.

Due to the material problem of this grinder, Zhang Qingfeng did not dare to make the grindstone into a disc shape.

The main function of this machine is to help Zhang Qingfeng sharpen some parts, which is much faster than him using a file to grind a little bit.

Under Zhang Qingfeng's operation, several parts were gradually processed into rough blanks.

Next, Zhang Qingfeng started grinding again with a grinder, and finally used a file to slowly grind, and finally used a grindstone to slowly polish.

When Li Kui brought the middle-aged man to find Zhang Qingfeng, Zhang Qingfeng had just finished processing and polishing all the parts with a dozen students.

After Li Kui and the others arrived, Zhang Qingfeng received a group of people in a machine workshop.

"Teacher. Let me introduce you. This is Long Live Tinghou..." Li Kui introduced the middle-aged man to Zhang Qingfeng.

Then he introduced Zhang Qingfeng to the middle-aged man. "My lord, this is my teacher."

"I'm Xun Yu, with the word Wenruo, I've met Mr.

Before Zhang Qingfeng could speak, the middle-aged man saluted Zhang Qingfeng first.

It turned out that the middle-aged man who followed Li Kui into the mountains was Xun Yu, Cao Cao's first counselor.

Xun Yu is 42 years old this year, but Zhang Qingfeng is in his fifties this year, and looks much older than Xun Yu, so Xun Yu took the initiative to greet Zhang Qingfeng without any pretensions.

At this time, Zhang Qingfeng's clothes were dirty because he was processing and polishing the parts just now. Even so, Xun Yu didn't have any intention of belittling him.

"It's a pleasure to meet you. Zhao Wen, whose name is Ruixiang, met Tinghou." Seeing that Xun Yu was so polite, Zhang Qingfeng also bowed his hands to Xun Yu to salute.

"Mr. Ruixiang, you don't have to be so polite. I took the liberty to visit and didn't disturb you, did you?" Xun Yu asked Zhang Qingfeng.

"No, no, it's an honor for Mr. Wen Ruo to come to see me. This place is a bit shabby and the reception is not good. I hope you won't blame me." Zhang Qingfeng said to Xun Yu.

"Mr. Ruixiang, I came this time mainly to meet you and ask you some questions. Also, you have taught a group of good students." Xun Yu said to Zhang Qingfeng.

"Mr. Wen Ruo's love, they learned it by themselves." Zhang Qingfeng is modest.

The two talked to each other, and they were very polite in terms of address and tone.

"Mr. Ruixiang, what is this?" Xun Yu asked Zhang Qingfeng, pointing to the milling machine beside him.

When he came here, he saw this milling machine, but Zhang Qingfeng had already turned off the shaft connection device, so this machine was not working.

Even so, the milling machine just placed there is extremely eye-catching.

Xun Yu was able to bear it until this time before asking, which is considered very self-restraining.

"This is a hydraulic machine I made, mainly for processing steel parts." Zhang Qingfeng explained.

"Oh." Xun Yu nodded, but he didn't understand a word Zhang Qingfeng said.

What processing, what steel parts, made him a little confused.

Perhaps seeing Xun Yu's confusion, Zhang Qingfeng simply said to Xun Yu: "Let me show you my machinery."

After speaking, Zhang Qingfeng walked quickly to the shaft connector, and connected the shaft of the waterwheel to the transmission device of the milling machine.

With the connection of the two shafts, the next moment, the speed change device starts to work, and the big wheel leads to the small wheel, which instantly makes the transmission shaft of the speed change device rotate rapidly.

Next, Zhang Qingfeng connected the transmission device to the milling machine.

In an instant, the cutter head of the milling machine also rotated rapidly.

Seeing this scene, except for Zhang Qingfeng's students, everyone was very surprised.

Including Xun Yu, they were also extremely surprised.

"Mr. Ruixiang, what is this for?" Xun Yu asked Zhang Qingfeng.

"Let me demonstrate it to everyone, and everyone will understand after reading it."

Zhang Qingfeng found a piece of wrought iron, and then clamped it with a clamp. Then, under the gaze of everyone, he began to shake the handle, manipulating the workbench to rise upwards.

His milling machine has no way to press down the rotating milling head, so he can only raise the table to process parts.

Under everyone's gaze, the milling head gradually met the wrought iron on the workbench.

After hearing a rustling sound, the cutter on the milling head began to cut the piece of wrought iron, and a large amount of iron filings came out.

"My God, cut iron like mud..."

Seeing this scene, many people couldn't help exclaiming.

As the workbench continued to rise, soon a slot with thin chopsticks was milled out.

After milling, Zhang Qingfeng turned off the milling machine and took out the piece of wrought iron and handed it to Xun Yu who was beside him.

Xun Yu took the wrought iron and carefully looked at the groove that was milled out. He couldn't help but praise and said: "It's really like cutting iron like mud. It's really awesome to be able to cut out a groove in such a thick iron."

"However, Mr. Ruixiang, I want to know, although this machine can dig grooves in iron, what is the use?" Xun Yu asked Zhang Qingfeng.

"Of course it is useful, and it is beneficial to the country and the people." Zhang Qingfeng said in an affirmative tone.

"Oh? But I heard about it."

"Simple, because with this machine, more machines can be made."

Zhang Qingfeng gave an example: "In agriculture, I can use these machines to make a harvester. In the past, an ordinary farmer could only harvest a few acres of wheat a day. With the harvester, it is not a problem to harvest tens of acres or hundreds of acres."

"So powerful?" Xun Yu was surprised.

"More than that, in the military, we can also manufacture hydraulic stamping machines, and stamp arrows with stamping machines. One person can stamp tens of thousands of arrows in a day, and how many arrows can a blacksmith make in a day? Dozens of arrows are the sky. .”

Zhang Qingfeng said: "You can also use a stamping machine to mint coins. The imperial court needs to make a mold to cast five baht coins, and then pour the molten copper into the mold. Not to mention time-consuming and laborious, the cost is also high."

"If there is a stamping machine, one person can easily press tens of thousands of five baht coins a day."

"With advanced machines, all kinds of things can be mass-produced by machines, such as swords, guns, swords and halberds, armor and crossbow arrows, etc. Others need tens of thousands of craftsmen to build weapons for many years to supply the consumption of an army, but With the machine, maybe only a few hundred people are needed to achieve the effect of tens of thousands of people."

"Therefore, with machines, weapons can be produced continuously. When a war breaks out, others shoot [-] arrows at a time, but you can shoot hundreds of thousands of arrows. The outcome of the war will be different."
