The more he came into contact with Seiko, the more Chongzhen Emperor Zhu Youzhen was in awe of the machinery industry!

It's an industry that looks simple, but never bounds to do!

In the world of science, no one can be proud!

Every part of the lathe is processed with great precision, and the masters are unemployed.

But in practice, it doesn't. For example, the spindle should be fitted with two bearings and installed in the head of the lathe. If the shaft and bearing are machined more precisely and the fit is smaller, the more difficult it is to install the bearing on the shaft, and even reduce the machining accuracy of the lathe due to misalignment. The same is true when the spindle system is installed in the head of the lathe. The reason for this problem is that this structural form theoretically determines that there will be these difficulties, and the more sophisticated they are, the greater the difficulties.

How the level 0 plane came out was to take two pieces of metal and grind them against each other. It looks very simple, but it can be ground a little badly, that is, one side is convex and the other side is concave. Of course, the actual situation is much more complicated, and there is more than one pair of people involved in the grinding, the convex one is convex, the concave one is concave, and finally a pair of 0-level planes are obtained after many times of grinding. You know, in the early 90s, level 8 fitters worked outside, and there was no less than 30 yuan for 1 hour, and it was very high for college students to get 300 yuan / month at that time.

Some people will ask, even if the hands of the masters are extremely skillful, but with such high precision, how do the masters know which side is in place and which side is not in place in the processing? I can't answer this question in detail, because for different manual processing situations, the masters will design different methods to detect in the processing process, and the more commonly used means are hand touching, eye seeing, optical shadow magnification, etc. Among them, the feeling of the masters is extremely important. Like what. Ordinary people have no problem looking at the same processed surface, they can know what is wrong at a glance.

Chongzhen Emperor Zhu Youzhen in modern times, originally had the experience of working in the factory, manual not only refers to fitters, turning, milling, planing, grinding and other types of work, there are 8 level workers, everyone's machine tools are the same. The accuracy and efficiency of the master machining are much higher than the average person, when the lathe is clamped for the second time, the error of the 8-level tooling can be smaller than the machining error of the lathe, and the 8-level workers often process the parts that are much higher than the machining accuracy of the machine tool. Even in the current era of CNC, a good mechanic is irreplaceable, don't think that it is advanced CNC equipment anyway, as long as the operator can program, of course, level 8 technicians must also keep pace with the times, learn programming and other new knowledge.

Someone will say. Manual work is entirely talented, and experience cannot be passed on. So you can't expect good mechanics. This statement is very wrong, the craft can be inherited, but also can bring forth the new, the technicians themselves must master considerable theoretical knowledge, and those who have seen the previous examination of the technician level will know this. Good craftsmanship requires talent, but it does not depend entirely on talent, and the acquired factor accounts for a considerable proportion. The craftsmanship of the technicians can be summarized on a large scale, and the level of technicians can be greatly improved on the whole. In the past, large state-owned enterprises all had technical schools, and the level of people who came out was quite good.

The more advanced the technician, the lower the ratio of finished products, the cost is also very high, the time required is more, and the people are greatly affected by the outside world, so for the manufacturing industry, it is of great significance to reduce the requirements for operators.

Chongzhen Emperor Zhu Youzhen thought that more Ming craftsmen from the Ming Ordnance Manufacturing Bureau should become senior technicians, and he believed that this goal was not difficult to achieve. He just wants them to be able to read drawings, draw drawings, calculate the operation formula of specific equipment, and practice for a long time!

Chongzhen Emperor Zhu Youzhen decided to expand the scale of the Ming Ordnance Manufacturing Bureau again, anyway, the Beijing division is still in the post-war reconstruction, and there are places! Chongzhen Emperor Zhu Youzhen, who felt that the progress was too slow, still decided to temporarily move the Jingshi of the Ming Dynasty to Tianjin, where he could start developing ironclad ships more quickly! Otherwise, trade with Japan was not only interrupted, but these Japanese dogs also colluded with Xu Xinsu and the Dutch to cause disaster to the Ming coastal defense, and it would not work without ironclad ships! He must move the capital to the port of Tianjin!

Chongzhen Emperor Zhu Youzhen didn't understand why the ancestor Zhu Di's grandfather wanted to set the capital of Beijing, in terms of geographical location, Tianjin Port is easy to defend and easy to escape! More appropriate, right?

Of course, Emperor Chongzhen Zhu Youzhen will not be called Qiandu so much, he gave a nice name, inspection!

Anyway, when the imperial palace in Tianjin was built, a secret passage was also arranged to facilitate him to leave the palace!

Chongzhen Emperor Zhu Youzhen took great difficulty to lift a hemp cloth bag he had prepared! This is the last big bag of parts he needs to get Da Ming! With these, all the equipment he needs in the near future, as well as the techniques that his abilities can reach, are available!

Fire scooping technology is actually not difficult, Chongzhen Emperor Zhu Youzhen in modern times, checked on the Internet, and found it, and with the chemical technology he learned in pharmacy, it is possible to make fire scooping, this kind of smokeless fire scooping is much more awesome than the black fire scooping of the Ming Dynasty! What he has to do now is to produce bullets, on a large scale, at least enough for the more than eighty armed eunuchs in the West Factory to practice marksmanship and fight Jiannu!

Then it's time to build ships, build large ironclad ships! He prepared the drawings and models, it is a model of a decommissioned torpedo destroyer after World War II, and it did not cost money, these are on the Internet, on the gathering websites of those military fans, they can be downloaded very simply, in modern times, in fact, there are not many secrets, but the civilian does not have the technology and the venue, if the civilian warship is early, eighty percent of the shelves have not been set up and run inside to lie down.

As soon as he was ready, Chongzhen Emperor Zhu Youzhen was about to go to find Wen Chengtai to cross, and now he is also proficient, and he points Wen Chengtai's sleeping hole before each crossing, so as not to make people suspicious, anyway, after he leaves, it turns out that the space is not gone, no matter how long he walks, it is the same as staying in that second!

"Are you really obsessed? You don't sleep all day long, you've been working on these things, are you really going to be a scientist? Lan Qiwei suddenly came in.

Chongzhen Emperor Zhu Youzhen hurriedly withdrew his hand, and just wanted to attack Wen Chengtai, who was playing with the computer next to him.

Chongzhen Emperor Zhu Youzhen smiled slightly, "What are you doing?" Looking for me or looking for him? ”

Lan Qiwei glanced at Xun Lou, "Who is looking for him as a child?" (To be continued......)
