Chapter 1142

"Each part is the same size, and the biggest difference will not be worse than two lines, which is two-tenths of what you call a millimeter." Zhao Ji picked up a few parts, put them together, and casually brought a 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 couldn't help but nod with satisfaction. "It seems that Your Highness, you have really done a lot of work in the past few years."

The so-called one line and two lines refer to 0.1 millimeter and 0.2 millimeters, and now, the smallest unit of measurement is the cotton thread produced by North Shaanxi Road.

Ten cotton threads are listed side by side as one millimeter, and ten millimeters are one centimeter, which is the unit of measurement for length used by craftsmen formulated by Wang Daguanren.

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

"Mr. said with a smile, Xiao Wang did a lot of this, but it was because of your suggestions. For example, this vernier caliper, I didn't expect it to be in the late Eastern Han Dynasty, and such a measuring weapon, but for some reason, it disappeared for hundreds of years. ”

"And this kind of machine tool you designed, sir, if we don't have this thing, if we polish these parts by hand, I'm afraid that such a screw will require an experienced craftsman and take several days."

"And it is precisely with machine tools that each machine can produce thousands of screws per day." Zhao Ji raised his hand and pointed to the machine tool not far away, and said with a smile.

Wang Yang paced over, these machine tools, not so much machine tools, but more like an improved version of the manual pedal sewing machine.

Sewing machines are used to sew clothes, but nowadays they are used to make small parts, and for large parts, there are several hydraulic machines next to them that specialize in cutting and making large metal parts.

In Wang Yang's eyes, whether it is the Yuanyou crossbow or the Yuanyou stone throwing machine, even if these things are taken into the hands of the enemy country and imitated, Wang Yang will not feel very distressed.

What he is most worried about is these machine tools, machine tools, which are an important part of the machinery industry in Wang Daguan's mind. This thing is machinery that is specifically used to make machines.

That is to say, the machine tool or the machine tool, the use of manpower or water power can not only be used to make screws, or gear processing, or internal grinding...... It can also be used to process and cut various metals, and the artillery of the future will also need the help of this kind of machinery.

Machine tool technology is the fundamental and core technology of the Song Dynasty to surpass the surrounding countries.

"Sir, don't worry, none of these things will ever go out, every tool has a code, and even the names of these users are engraved."

"In addition, this armory supervision workshop is absolutely not allowed to outsiders to enter or leave, and all the daily necessities will be handed over to the forbidden army to be sent directly into the workshop fortress, and then distributed according to needs......

It has only been completed for less than a year, and the number of meticulous works that have died inside and outside the city has exceeded a hundred......"

With Zhao Ji's explanation, Wang Yang frequently bowed his head, this small city fortress less than two miles in a radius actually used 5,000 elite forbidden troops to guard it, and it was able to do such a careful arrangement and strict guarding, which is enough to prove that the Son of Heaven attaches great importance to these things.

Each workshop in the city fortress has a different division of labor, so that even if the craftsmen inside abscond out, the loss to the Great Song Dynasty can be eliminated to the greatest extent, at least it is only a point, not the whole surface.

For example, the craftsmen who use the machine tools are only responsible for the use, and the people who make and repair the machines are others. The four sides of each machine are tightly sealed with iron plates, and only after the work of the craftsmen is finished will the person in charge of maintaining the machine enter for maintenance and repair.

Each step is as detailed as possible, which makes the craftsmen more and more precise in their work, but at the same time, it also prevents them from fully grasping the entire process and structure.

Walking to another workshop, which was hot and rumbling, with the greeting of a foreman, a furnace of molten iron was slowly poured into the mold that had been prepared long ago, and then the wire drawing process began.

Watch as the steel wires are squeezed out of the crossgear, rolled around a round iron casting, and then carried out a secondary process, until finally, it becomes a steel spring of finger thickness that is very close in size and diameter.

"This is the shock-absorbing spring currently used on the bed crossbow, and after this thing, our bed crossbow no longer uses a wooden crossbow arm, but is made directly of mild steel like the Yuanyou crossbow."

"It's just that in this way, the consumption of steel is really amazing, so at present, it is mainly used for experiments, and only a small amount of steel bed crossbows are made......" Zhao Ji picked up a heavy spring with some regret, and slowly put it back after squeezing it in his hand.

These made springs made Wang Yang's eyes light up, and he also stepped forward to pick up a spring weighing several catties, it was really reliable, but I didn't expect these guys to really make it.

"Have you ever considered using it on other machines?" Wang Yang turned his head and asked the craftsman on the side, and learned that the load-bearing limit of such a spring could reach three or four thousand catties. However, the durability of this spring is not clear for the time being.

However, the appearance of this thing made Wang Yang think of many uses, such as today's self-striking clocks, horse-drawn carriages, and the use of various machinery and machine tools......

"Can this thing be used elsewhere?" Zhao Ji couldn't help but look at Wang Yang with some astonishment.

"Of course you can, and the demand for this thing will be huge. It's going to be a big business......" Wang Yang smiled and played with the spring, the light in his eyes was unbelievable.

Seeing Wang Yang's appearance, Zhao Ji's eyes couldn't help but light up. "Really?"

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

Hearing this, Zhao Ji couldn't help but gasp, just by virtue of the printing house, even if he didn't have a lot of shares in it, a few percent of it had to be handed over to today's son. But with the profits there, in just a few years, he has accumulated a huge amount of more than one million yuan.

Now hearing Wang Yang's words, it naturally tickled Zhao Ji's turbulent heart so much that it was unbearable. But after seeing Wang Yang throw the spring to that side and pat his ass to look at other things, he could only endure it.

But it doesn't matter, as long as Mr. comes back, with Mr.'s smart mind, do you still have to worry about not making money?
