Steel Dynasty - Chapter 839

[Chapter 838 The gateway of industry]

The palace maid in the royal study room shook the fan, blowing the slightest cool breeze onto Xiao Ming and Lin Wentao.

Under Xiao Ming’s explanation, one lathe structure and image after another appeared in Lin Wentao’s mind.

“The length measuring machine that the emperor mentioned is already being tested at Qingzhou College. It uses the measurement units established by the emperor. However, the most accurate length measuring machine that can be realized at present can only be one thousandth, and before we build the length measuring machine, we still have It is necessary to divide the millimeter level into equal parts, so that the scale of the length measuring machine can be set to one thousandth.”

Lin Wentao’s words made Xiao Ming nod. This was exactly what he wanted to say.

At present, the measurement accuracy of Dayu basically remains at one percent, which is millimeter level.

But if he wants to manufacture locking structures and other more precise machinery, he must increase the measurement accuracy to one thousandth, and in the future, even one ten thousandth.

“You are right, but the division of millimeters can only be done manually. I will provide you with a microscope, and you can try to divide millimeters into equal distances,” Xiao Ming said.

Lin Wentao nodded. The issue of accuracy has always been a headache for him.

In fact, in his opinion, whoever masters industrial precision will master mechanical manufacturing. After all, machine tools are also called industrial mother machines in Qingzhou University books. As the name suggests, these machine tools are the mother of machinery.

“It’s just that in this way, our scale will inevitably have some errors.” Lin Wentao was a little regretful.

Xiao Ming frowned. In fact, accuracy is only a relative issue, not an absolute issue. Even contemporary rulers produced in the same batch will have errors in their scales.

Therefore, whether it is the accuracy of the lathe itself or the accuracy of the manufactured parts, there are errors. The industry only needs to control the errors within a certain range.

Because of understanding this, Xiao Ming was not as confused as Lin Wentao.

This confusion is where the original scales came from, such as meters, centimeters, millimeters, etc. In contemporary times, people may not think about the issue of ruler scales because everything is ready-made.

But at this point, he had to explain that the original scales were actually drawn by hand, just like he drew the weights and measures of the Great Chongqing Kingdom with his own hands, and used this as a standard.

The craftsman then uses this scale to create measurement units, and then uses the lathe to produce parts with a certain degree of accuracy.

Because of this, in fact, the accuracy of spare parts manufactured in Dayu can only rely on manual polishing. There is no other way. After all, in theory, only human hands can achieve infinite accuracy. This is how the accuracy of lathes has evolved in history.

In the contemporary West, standards of weights and measures have been formulated, and other countries can only imitate each other’s measurement units. In this way, it is difficult to imitate to the nearest hundredth, and can only be approximate.

What Xiao Ming and Lin Wentao are doing now is actually establishing the industrial precision of Dayu and building the manufacturing tradition of Dayu, and the foundation of manufacturing tradition still lies in the rigor of the craftsmen.

“Errors are inevitable. There is no absolute equidistance. We can only reduce the error to the minimum. Once an accuracy standard of one thousandth is established, we can make one thousandth of the vernier caliper, and then we can make ten thousandths of it.” One-third length measuring machine,” Xiao Ming said loudly.

The mass production of breech gun spare parts is a node for Dayu’s industrial breakthrough. Once this node is broken through, Dayu will embark on the road of precision manufacturing.

In this process, he also needs to manufacture precision levels, dial indicators, right angle meters, flat rulers, high-precision spindle mandrels and dial indicator rods. But before that, he must have a precision level of one thousandth. original scale.

This was also one of the reasons why he asked Lin Wentao to come here this time. He wanted Lin Wentao to manually polish a vernier caliper with an accuracy of one thousandth.

“Yes, Your Majesty.” Lin Wentao nodded heavily. He was under great pressure.

After returning, he decided to mobilize all the craftsmen to engrave this vernier caliper with an accuracy of one thousandth, and selected a caliper whose error could not be distinguished by the naked eye as the original caliper.

After that, the machinery for manufacturing vernier calipers will be mass-produced, and then the vernier calipers will be used to manually manufacture other tools to ensure accuracy.

The teaching between the two lasted until about three o’clock in the afternoon. Through the explanation, Lin Wentao basically understood the issue of accuracy.

After leaving the palace, Lin Wentao went directly to Qingzhou University. Next, he will lead the students to establish the industrial precision standards of Dayu and formulate a set of parts size specifications. But first, he needs to manufacture an original vernier caliper with an accuracy of one thousandth.

While Lin Wentao was busy, Xiao Ming was not idle either. He summoned Li Chuyuan, the eldest son of King Chu.

It has been more than two years since this miserable prince of Chu was thrown to Qingzhou because of King Chu’s ambition, and his way back is still far away.

“The Crown Prince of Chu, Li Chuyuan, is here to see the Emperor.”

In the royal study, Li Chuyuan bowed ninety degrees and lowered his head deeply.

He has been living in Qingzhou for the past two years. Feeling the growing wealth and power of Qingzhou, he became more and more uneasy. Especially after the defeat of the Golden Horde, he did not sleep all night. He dreamed about one problem at midnight. Confrontation with Xiao Ming, Chu State What will happen?

At this time, Xiao Ming sat down on a chair in the imperial study and was drinking tea. He said to Qian Dafu, “Give me a seat.” Qian

Dafu responded and asked the eunuch to bring a chair to Li Chuyuan. Li Chuyuan hesitated and sat down. Go up.

The two sat opposite each other, and Xiao Ming was not in a hurry to speak. Instead, he handed the news about Cao Zhengyang’s interrogation to Li Chuyuan and let him read it first.

Li Chuyuan was a little confused at first, but after seeing it, his face became increasingly ugly.

“Wishful thinking, wishful thinking!” Li Chuyuan’s angry hands trembled slightly, “Where will the Cao family put my father? Where will they put me? Your Majesty, Chu State is my fiefdom and cannot fall into the Cao family’s group. In the hands of thieves.”

Li Chuyuan’s reaction made Xiao Ming very satisfied. According to his understanding, he was a little dissatisfied when the King of Chu sent Li Chuyuan to Qingzhou. Now that his kingdom was about to change, how could he not Worry.

“I’m afraid that both you and King Chu were kept in the dark by the Cao family. Since the Cao family wants to take power, how can there be anything going on between you and your son in the future?” Xiao Ming said.

Li Chuyuan nodded. He knew what was happening in Chu State, but he did not expect that the Cao family would have such evil intentions. They were waiting to have all the power to kick them away.

“Your Majesty, my father has been blinded by lard. Please allow me to write a letter to persuade my father.” Li Chuyuan said urgently.

Xiao Ming narrowed his eyes. He believed that the King of Chu would not pay attention to Li Chuyuan’s letter. After all, the current King of Chu was already a little crazy and had lost his mind, and he did not want the King of Chu to rein in the situation.

So he said, “Your father will not listen to you now. I only ask you, do you want to be a homeless dog, or do you want to be rich and powerful in the rest of your life!”
