When people flocked to various garment shops to buy affordable garments, Li Kuan came to the production workshop of the sewing machine "the culprit" that caused this change - Guanshishan Academy Machinery Workshop.

As the first workshop to be built in the academy, the machinery workshop now has more than 300 R&D personnel, and the craftsmen responsible for testing and sample production. Even if they are not considered helpers in the production workshop, the machinery workshop has a scale of more than 800 people.

Such an institution with quite modern characteristics is more like a large research institute or a large company driven by R&D.

"Your Majesty, this is a hydraulic lathe processed according to the drawings you gave. Many parts on the sewing machine can be processed because of this hydraulic lathe."

As the person in charge of Guanshishan Academy, Liu Jie personally accompanied Li Kuan to inspect the mechanical workshop.

It has been more than ten years since the establishment of Guanshishan Academy workshop. The Tang Dynasty's economy has also developed rapidly for more than ten years, and the technology in all walks of life has been greatly improved.

Li Kuan felt it was time to consider improving the technological level of Datang.

As the mother of industry, machine tools are naturally the equipment that Li Kuan needs to consider first.

Although there is no electricity to drive it, the use of water trucks in Datang is relatively mature.

As the most primitive machine tool, it is barely enough to use hydraulic power to drive it.

The most important thing is that with the machine tool, the processing of various metal parts will become much easier.

In addition to casting and forging, machining will become a new skill that the craftsmen of the Tang Dynasty need to master.

"What is the difference between the bolts processed using this lathe and those processed at level 8?"

Li Kuan attaches great importance to the production and production of industrial standard parts such as bolts and screws. In his opinion, no matter what mechanical equipment it is or new technological products, if the basic parts such as bolts, nuts and bearings are not well made, it is impossible to have good products.

"Prince, I'll answer this question."

Dai Quan, who was standing behind Liu Jie, stood up.

As the first craftsman to win the title of eight-level worker since the Chu King’s Mansion introduced the craftsman assessment system, Dai Quan has a very high authority in various workshops.

Seeing that Liu Jie seemed a little hesitant, obviously not very sure about Li Kuan's question, he immediately stood up.

"Master Dai, then let's talk about it."

Li Kuan still respects his craftsmen.

He can get angry with people like Wang Fugui, but he rarely loses his temper with craftsmen like Dai Quan.

"In terms of production efficiency, the number of bolts that a water lathe can process in a day is hundreds or even thousands of times that of manual labor."

Dai Quan said a very sensational number from the beginning.

Sales volume increased by hundreds of times...

When Liu Jie heard this number, he thought the other party had drunk too much.

But who is Li Kuan?

Population processing bolts, the thread alone can make you collapse.

Even if you are busy from morning to night, you can't process extra-collection and bolts.

However, if you use a lathe, as long as you are more skilled in your hands and feet, you can process hundreds of bolts a day, which is a breeze.

Li Kuan was prepared for this, so he calmly signaled Dai Quan to continue.

"Although the production efficiency of lathes is very high, we can only produce some relatively large bolts and parts, and the processing accuracy is not particularly high. When encountering some small parts with very high accuracy requirements, we still need to rely on craftsmen to make them.

So if you only have a bolt, it is definitely better to be processed by eight-level processing; but considering large-scale production, lathes have incomparable advantages. For example, some bolts with low precision requirements used on Mercedes-Benz four-wheeled carriages can be processed using lathes, and there is no problem to directly reduce the cost by half."

"Oh? The machining accuracy of hydraulic lathes is not high. Do you have any good solutions?"

The accuracy issue may not be a particularly big problem now.

But with the development of industry, this issue will become more and more important.

If you don’t meet the accuracy of things like internal combustion engines, you will not be able to produce qualified products at all.

Even in later generations, China's machine tools were generally not as accurate as those used by Germany, which led to China being the largest machine tool producer and consumer in the world, but also the largest machine tool importer in the world.

Because high-end machine tools basically need to be imported.

There are also various laboratory instruments and equipment, which generally have very high requirements for accuracy.

Because they are originally used to measure the accuracy of parts or parameters of various substances. If their own accuracy is not good, then there is no meaning of existence at all.

But China has always been a weakness in this regard.

So you will find that almost all the instruments used in various laboratories are imported if they are related to high-quality and high-tech.

"Prince, our current solution is to use a hydraulic machine tool for rough processing first, and then use a human machine tool for fine processing, which can not only exert the high efficiency of the hydraulic machine tool, but also improve the accuracy."

Li Kuan originally thought Dai Quanhui had no choice.

Unexpectedly, I could hear a rather surprising answer.

“Human machine tools?”

Li Kuan has never heard of this word.

Even in my previous life, when I was in a metalworking internship, the lathes that I used in the Soviet era were all powered.

"Yes, hydraulic machine tools, as the name suggests, use hydraulic power as the main driving force for rotation in the spindle box, so that parts can rotate quickly; while human machine tools use manual shaking of the handle to rotate the workpiece, so as to facilitate the tool to process it.

If the processing volume is very large, it is difficult for human-powered machine tools to handle it, but if it is just a subtle progress adjustment, it can reflect its advantages. We are planning to promote lathes first in the Mercedes-Benz four-wheeled carriage workshop, Langqing watch workshop and permanent bicycle workshop."

Dai Quan’s words are easy to understand, and Li Kuan can understand them as soon as he hears them.

"Liu Jie, the academy should increase its support for the research of various new technologies, and do not be afraid of spending money. If you spend money today, you can earn tens of them in the future. All the workshops under the academy do not need to be paid for the money earned every year. Except for the operation and use of Guanshishan Academy, everything else is devoted to the research work of various research institutes."

Li Kuan himself doesn’t have so much time to stay in the laboratory, nor does he want to stay in the laboratory every day, so it is necessary to encourage others to stay in the laboratory.

Otherwise, how could Datang's industrial technology improve?

"Your Majesty, don't worry, Guanshishan Academy's support for the research of various new technologies is beyond the reach of any place; like the Steam Engine Research Institute, it has spent more than 10,000 dan in recent years, but the Academy has never restricted it. As long as there is a funding application, I will directly approve it.

There are also the Shipbuilding Institute and the Electrical Energy Institute, both large funds consumed, and the academy did not impose any restrictions on their funds. Except for some really strange things, we all meet the requirements of the teachers in various institutes at any time."

When Liu Jie was talking, he felt relieved.

Fortunately, after hearing Xu Jingzong's words, I never discounted my support for various research institutes.

Because many research institutes were established by Li Kuan.

"What's weird? For example?"

Li Kuan suddenly became a little curious about what the strange things Liu Jie mentioned were raised by the various research institutes.

"Let me give an example. Just a few days ago, a student named Wang Zhongqi from the Shipbuilding Research Institute proposed to use steel to make a ship, saying that such a ship is more durable and can be built larger; but this proposal is too strange, right? Using steel to make a ship will sink into the water as soon as it reaches the water? Wang Zhongqi even asked for a fund of 10,000 jin as soon as he opened his mouth, so I rejected it without thinking.

For example, there was a student from a mechanical workshop who proposed to make a four-wheeled carriage that could walk by himself. No, it could not be called a four-wheeled carriage, it should be called a four-wheeled carriage that could walk by himself. He proposed to apply for fifty craftsmen and three thousand stanchions of funds to support his project, and I also denied it without even reading it."

Liu Jie cited two cases that he thought were strange one after another, and he also saw that Li Kuan was indeed shocked by what he said, and he was quite proud of it.

I am the person in charge of Guanshishan Academy, and I am still very responsible.

"You just said that there are students in the Shipbuilding Institute studying the production of iron ships?"

Li Kuan was surprised to find that the "strange thing" Liu Jie said was actually like this.

This is not a strange thing, it is obviously a surprise thing.

Although Datang did not have the ability to make iron ships in a short period of time, nor did it have a supporting steam engine to cooperate with the iron ships, this is only temporary.

In a few years, the Tang Dynasty may have demands in this regard.

If I only started researching at that time, I would definitely waste a lot of time.

As a result, there were students in the Shipbuilding Research Institute with such a unique vision, which was early on locking in this research direction that most people could not understand.

"Yes, he is a student named Wang Zhongqi. He just studied in our academy for two years. He didn't know that he had made such an incredible proposal and asked for 10,000 jin of funds. I really doubt his motive."

"You arrange someone to call him over!"

Li Kuan glanced at Liu Jie and asked him to call him someone!

At this time, Liu Jie also discovered that Li Kuan's expression seemed to be a little different from what he imagined.

Did you not do anything well today?

Liu Jie couldn't help but recall today's scene from beginning to end, but didn't expect anything that was not done well.

However, Li Kuan had instructions, so he immediately went to correspond.

Soon, a slightly fat student came to Li Kuan.

"Student Wang Zhongqi, I have met His Highness the King of Chu!"

Wang Zhongqi looked at Li Kuan with great anxiety.

Some time ago, he proposed a scary proposal during his 18-year funding application in Zhenguan, which has become a joke among many people.

He thought that Liu Jie had said something in front of the King of Chu's Palace that he would have to be laughed at again today.

"You proposed the idea of ​​an iron ship?"

Li Kuan looked at Wang Zhongqi and didn't think there was anything special about him. His bones were not strange at all.

"Your Highness, King Chu, I came up with it alone!"

Wang Zhongqi's face became dimmed, and sure enough, it was still for this matter.
