Professor Gu Luotu nodded, seemingly satisfied with Jian Xunlou's answer. Yan Ting was a little strange, "Daddy, why did the guests come to the house?" You've been here all day long, do you even have to be here? ”

Professor Gu Luotu laughed and patted Yan Ting's hand, "Didn't you always want me to teach you the art of watchmaking?" I'll teach you now, you and the two of you will learn together, okay? ”

Emperor Chongzhen Zhu Youzhen was overjoyed, he was already able to make simple hammers, drills and other tools with some tools such as lathes! But mechanical manufacturing, is not as simple as he imagined, in this half a year, he has actually been back and forth between the modern and Ming more than ten times, almost all the modern tools in his warehouse have been moved to the Ming, however, he found that even if these things are moved to the past, in fact, for him, the role is not huge, not what can be done with tools, industrial hens are definitely not so simple!

The industrial machine is the machine used to make the machine. Such as: lathes, planers, milling machines, drilling machines, grinding machines, boring machines, etc......

No matter how good a technician is, it is impossible to process parts that exceed the accuracy of the machine tool in batches with a single machine tool - high-precision parts are obtained by relying on fitter adjustment and batch picking.

Industrial hens are stored in zài, and they refer to different things in different eras. In the 18th century, large-diameter high-precision lathes and boring machines (basically one thing) were industrial hens, after the mid-19th century, high-grade milling machines were industrial hens, and after the mid-20th century, high-precision multi-axis CNC machining centers were industrial hens. The so-called industrial hens. It is the equipment that determines the highest processing capacity of your machine. With this device. You'll be able to manufacture (of this era) ordinary machines in batches at a relatively low cost.

For example, high-precision planes are not inspected by touch. It is made up of specialized detection equipment, the most commonly used is the grating. Chongzhen Emperor Zhu Youzhen was alone in Daming, even if he had a complete set of tools, he found that he had no way to produce a machine tool that was exactly the same as the CNC machine he brought over! His skills are still very lacking!

There is no shortage of skilled craftsmen in the Ming Dynasty, in fact, the elites of the ancients in handmade zuò are quite outstanding! He has already changed Wang Chengen's mansion into the Daming Ordnance Manufacturing Bureau! And recruited a large number of master blacksmiths, but even so, he was not able to bring these modern tools. Copy it, if you can't do this, he won't master the industrial machine tool!

Yan Ting was very happy when she heard that her father was finally going to teach her how to make watches, and clocks and watches were precision instruments for measuring and indicating time. Clocks and watches are usually distinguished by the size of the internal machine. According to international practice, a clock with a diameter of more than 80 mm and a thickness of more than 30 mm is a clock; Those with a diameter of 37~50 mm and a thickness of 4~6 mm are called pocket watches; watches with a diameter of less than 37 mm; If the diameter is not more than 20 mm or the movement area is not more than 314 square mm, it is called a female watch. Watches are one of the smallest, most robust, and most sophisticated pieces of machinery ever invented.

When Yan Ting and Jian Xunlou were in school, they had already learned how to make tsuò clocks, but they did not reach the art of watchmaking. "Daddy, you're really eccentric. I can only learn it with this inspection building? You should have taught me a long time ago, don't you always say that if a person can make a perpetual pocket watch from nothing, then he can make parts of any machine in the world? ”

Professor Gu Luo Tu smiled slightly, "Yes, that's what I mean, you and Jian Xun Lou have not reached this level, especially you, you are slightly worse than the level of Jian Xun Lou, I am looking at Lan's face, teach him in advance, you are stained with his light, follow him to learn, you know, a music master, if you are willing to teach a person who has just learned stave to play the piano, this is a very tiring thing." ”

Yan Ting knocked on her mouth, but Lan Boxiong was very moved, "Professor Gu Luotu, my father and I know this, you are one of the top mechanical manufacturing experts in the world today, if you want, even a senior expert of the US Department of Defense, but you are willing to be a professor in a university, this kind of kindness of teaching Xunlou, my father and I have it in mind." ”

Chongzhen Emperor Zhu Youzhen was secretly surprised, he only knew that Professor Gu Luotu was very powerful, but he didn't expect that he had reached such a strength? Even more secretly ecstatic! Hurriedly follow and thank you!

In the pre-industrial period, there was no concept of industrial hens. Because at that time, everyone's equipment could be made by themselves, because the industrial development process at that time was low, the technology content was not high, and the engineers were basically generalists (not the guys who can only talk on paper now, but they can really do anything), and they can design and manufacture them themselves.

With the development of science and technology in the process of industrialization, there are more and more disciplines, engineers have begun to specialize, generalists are becoming more and more scarce, Chongzhen Emperor Zhu Youzhen just wants to be such a generalist, just like the Olympics, it is said that someone used to be able to win gold medals in more than 10 different events, and now one can be won is the ancestral tomb smoke. As a result, the industrial hen industry, represented by machine tool factories, appeared. Without them, other industrial plants may not be able to sustain production and development.

What exactly is an industrial hen? In layman's terms, it is to be able to use the machine qì to make the machine qì, which is the machine qì used to make the machine qì. Unfortunately, this statement is wrong.

A hen, as the name suggests, is a hen that lays eggs. However, the eggs laid by industrial hens are not for eating, they are used to hatch chicks, and the eggs laid by hatched chickens are for eating. This is the first level of concept, and that's how many people recognize it. The hatched hens can also replace the original hens as industrial hens. This is the second level of the concept, and people with higher levels know it this way. Some people also believe that with a bed with a precision of 0.1mm, and then use a bed with a precision of 0.1mm to make a bed with an accuracy of 0.01mm, which is called industrial hen capacity. This is the third level of concept. However, in fact, there is no industrial machine tool, there was no in the past, there is no now, and there will be no in the future. It's just a figurative concept.

I have to say that Emperor Chongzhen Zhu Youzhen worked very hard! I worked hard to the point that I didn't want to sleep, and the whole person was a little crazy, but technology is a long-term accumulation, and he still has a long way to go to achieve the level of independent production of guns and cannons!
