Chapter 1133 Machine tools are the core technology and foundation (first update)
Chapter 1142

"Every part is the same size, and the biggest difference will not be two lines apart, which is what you call two-tenths of a millimeter." Zhao Ji picked up several parts and put them together. He casually took another vernier caliper made of steel from the side and handed it to Wang Yang.

Wang Yang took the vernier caliper, looked at the neatly etched centimeters and millimeters on it, and nodded in satisfaction. "It seems that your Highness has really done a lot of work in the past few years."

The so-called one line and two lines refer to [-] mm and [-] mm. Nowadays, the smallest unit of measurement is the cotton thread produced by Shaanxi North Road.

Ten cotton threads are juxtaposed into one millimeter, and ten millimeters are one centimeter. This is the length measurement unit used by craftsmen formulated by Wang Daguan.

The difference between these finger-thick parts is just as Zhao Ji said, the difference is only between one or two lines.

"Sir, you are joking. Most of what Xiao Wang did was because of your suggestions. For example, this vernier caliper was already available at the end of the Eastern Han Dynasty. This kind of measuring tool, but for some reason, it is not Lost for hundreds of years.”

"There is also the machine tool you designed, sir. If there is no such thing, if we polish these parts by hand, I am afraid that such a screw will require an experienced craftsman, and it will take several days."

"With the machine tool, the number of screws that can be produced by each machine tool every day is already counted in thousands." Zhao Ji raised his finger and pointed to the machine tool not far away and said with a smile.

Wang Yang paced over. These machine tools were not so much machine tools as improved versions of manual pedal sewing machines.

The sewing machine is used to sew clothes, but now, it is also suitable for making those small parts. As for the large parts, there are several hydraulic machine tools beside them, which specialize in cutting and making large metal parts.

In Wang Yang's eyes, whether it is Yuanyou crossbow or Yuanyou trebuchet, even if these things are in the hands of the enemy country and imitated, Wang Yang will not feel much distressed.

What he was most worried about was that these machine tools, machine tools, were the important structural part of the machinery industry in Wang Daguan's mind.This thing is a machine specially used to make machines.

That is to say, machine tools or machine tools, using manpower or hydraulic power, can not only be used to make screws, or to process gears, or to perform internal grinding... It can also process and cut various metals. Future artillery , also need the assistance of this kind of machinery.

Machine tool technology is the fundamental and core technology for Da Song to surpass the surrounding countries.

"Don't worry, sir, none of these things will be lost. Every tool has a code, and even the names of these users are engraved."

"In addition, outsiders are absolutely not allowed to enter or leave this weapons supervisory workshop. All living materials will be handed over to the imperial army and sent directly to the workshop fortress, and then distributed according to needs...

It took less than a year to complete the work, and the number of meticulous workers who died inside and outside the city has already exceeded a hundred..."

Following Zhao Ji's explanation, Wang Yang nodded frequently. This small fortress with a radius of less than two miles was actually guarded by [-] elite imperial troops. It was enough to prove the emperor's respect for these people. attention to things.

Every workshop in the city has a different division of labor. In this way, even if the craftsmen inside abscond, the loss to Da Song is at least only a point, not the whole noodle.

For example, these craftsmen who use machine tools are only responsible for using them, while other people make and maintain machine tools.The four sides of each machine tool are tightly sealed with iron plates. Only after the work of the craftsmen is finished, will the person in charge of maintaining the machine tools enter the site for maintenance and repairs.

Every step is as detailed as possible, making these craftsmen more and more precise about the work they are doing, but at the same time, it also prevents them from fully grasping the entire process and structure.

I wandered to another workshop, and it was so hot here, and the rumbling sound was deafening. With the greeting of a foreman, soon, a furnace of molten iron was slowly poured into the mold that had been prepared earlier. Then start the drawing process.

Watching the steel wires being squeezed out of the horizontal tool, they were rolled on a round iron casting, and then a second process was carried out, until finally, it became a piece of size and size. Finger-thin steel springs with very close diameters.

"This is the shock-absorbing spring currently used on bed crossbows. With this, our bed crossbows no longer use wooden crossbow arms. Instead, they are made directly of mild steel like Yuanyou's crossbow."

"It's just that the consumption of steel is too alarming, so it's mainly used for experiments at present, and only a small amount of steel bed crossbows have been made..." Zhao Ji picked up a heavy spring with some regret, After twisting it in his hand, he slowly put it back.

These prepared springs made Wang Yang's eyes light up, and he stepped forward to pick up a spring weighing several kilograms. It was amazing. Unexpectedly, these guys actually made it.

"Have you ever considered using it on other machines?" Wang Yang turned his head and asked the craftsman beside him. He learned that such a spring can bear up to three or four thousand catties.However, the durability of this spring is temporarily unclear.

However, the appearance of this thing made Wang Yang think of many uses, such as today's chime clocks, and carriages, and it can be used on various machinery and machine tools...

"Can this thing be used in other places?" Zhao Ji couldn't help but look at Wang Yang in shock.

"Of course, and the demand for this thing will be huge. It will be a huge business..." Wang Yang played with the spring with a smile, and the light in his eyes was hard to look at.

Seeing Wang Yang's appearance, Zhao Ji couldn't help but his eyes lit up. "real?"

"Of course it is true, and this business is many times bigger than that of the printing house..." Wang Yang lowered his voice and whispered in Zhao Ji's ear.

Hearing this, Zhao Ji couldn't help but take a deep breath, just relying on the printing house, even if he doesn't have many shares in it, a few percent of it has to be handed over to the current emperor.But relying on the profits there, in just a few years, he has already accumulated a huge sum of more than 100 million yuan.

Now hearing Wang Yang's words, Zhao Ji's restless heart was naturally itched to the point of being unbearable.But after seeing Wang Yang throwing the spring there and patting his butt to look at other things, he could only endure it.

But it doesn't matter, as long as the husband is back, with the clever mind of the husband, can I still worry about not making money?
