At first he thought this was just a simple gantry, but Bolu, who still hadn't learned his lesson, confidently boasted about it.
"I don't believe it! When did you finish the work on time? See you next month!" Leah glanced at him and walked away in the direction of the military camp.
Bolu also shouted behind her: "Hey! I'm serious, this is not difficult!"
One day later, all he wanted to do was slap himself in the face: "Let you nurse yourself without any problems, let you milk yourself without problems."
It seems like a simple thing, but it almost makes your liver burst when you make it.
The main structure of this cutting machine is a rectangular pool with longitudinal rails supporting a cutting head module that can swing laterally. The structure is not too complicated.
The water tank welded by steel plates was originally thought to be the simplest part. However, the steel plate cutting itself is currently limited by the cutting capacity. Only a few people can lift the steel plates to the bare head. Cutting the thick steel plates used in the pool is already laborious enough.
The key is that after cutting, you still have to weld it, and you need a few people to support it.
In the end, Case, his welding tools, and the welding team were transferred over. As a result, this seemingly simple pool drained every ounce of energy from more than a dozen big men.
What's worse is the stepper rack. In order to ensure the accuracy of the rack, Bolu had to take out his hand to strengthen the existing vernier caliper and measure it one by one with an accuracy of 0.1 mm. Bolu did it in half a day.
When one came out, I felt like my eyes were going to go blind. I spent the whole day grinding gears and did nothing else.
During the installation, I found that the rack and the water tank could not be adjusted to be fully level and relatively parallel. Finally, I found that the ground was uneven... I had to dig a hole on the ground on site, and then filled a piece of ground with cement.
After the level is scraped flat, leave it there to dry.
At this time, a group of people were too tired to hold on any longer. Seeing that Bolu had taken the lead and sat down on the ground, they all slumped on the ground, looking at the starry night sky, chatting one after another.
"Little manager, why are you so tired to make your things? I have been working as a blacksmith for so many years, and I have never stayed up so late this year. It's just this thing. It seems so simple, why do you put so much effort into it?
." Smith was lying on the ground and just raised his head and made some noise.
Polu also lay on a pile of steel plates and showed the word "Tai": "I didn't expect it to be so difficult. I stayed up a lot of nights this year."
"The foundation is still too poor, and none of us have much experience in engineering installation. We have done a lot of useless work. It seems that there are many processes and sequences that can be optimized. When this is completed, everyone can summarize it."
Bolu managed to get up.
"Worry, everyone has seen those monsters last time, and time is tight. If we don't work hard now, if we try again, we still won't have the ability to resist. No matter which way we die, we will be eaten by those monsters.
So strong."
"That's true."
"Okay! We don't have much to do at this point today. We need to surround this place and go back to rest quickly. We don't have to work tomorrow. Smith, please arrange a shift for them and have a good rest until the cement is dry. These are the same people.
, we will install it the morning after tomorrow!”
The workers went home to rest and did not have to work the next day, but Polu had to continue working the next day. Now a problem that had been deliberately avoided by using tricks began to show its huge impact on the machining accuracy.
For things made in the past, such as armor, if the rough processing accuracy can be about 1 mm, it is considered a good craftsmanship. The remaining problems mainly depend on the skilled craftsmen's manual assembly. Therefore, when a very small amount is produced, the craftsmanship is superb.
The old masters are still good enough to make armor after all. A little more is a little more. As long as it can fit together without leaking, you won't feel it.
Nowadays, the things we need to do are becoming more and more precise, and the impact of precision is becoming more and more serious. It’s not that craftsmen are unwilling to make things more precise. Some objective factors will obviously affect this, such as measuring tools. Polu believes that as long as it can be done correctly,
With precise measurements, their accuracy will definitely increase dramatically.
Blacksmiths have always been in the habit of using homemade rulers and calipers, but without anyone's help and relying entirely on hand tools, they worked hard to achieve about 0.7 mm, which is almost the limit under their current conditions. Nowadays, wave
Lu decided to take them directly into the 0.1 era.
He thought back to the mechanical precision measuring tools he knew. Nowadays, micrometers using precision screws are probably impossible to make. Although he knows the principle of this thing, he has never seen its internal structure a few times.
However, vernier calipers accurate to 0.1 mm are very commonly used, and measurement does not rely much on machining accuracy, but more on precise scales, so it is not particularly difficult to make. At this time, you need to ignore the slightly larger frame size between the caliper components.
After a little effort to select some finished products with relatively accurate scales, 0.05 mm is not a dream. It is basically enough at the current stage. No matter how high the precision is, Bolu cannot control it with his current ability.
After working hard, Bolu felt that he had reached his current limit: "Okay, the decision is yours!"
Using this vernier caliper as a benchmark, he sat in the studio where the apprentices were still producing crystal plates. He made several vernier calipers with a precision of 0.1. Some of them were handed over to Candice and asked her to
Teach her young apprentices how to use it. The other part is going to be handed over to the current factory. Although the knife forging is not so precise, sooner or later they will have to do other work.
"When the engineering team finishes building the roadbed, let them go to a short-term technical school when they come back! This situation cannot continue!" Polu was furious in his heart. He would rather temporarily reduce the labor force to let them all master basic common sense.
Otherwise, you will have to work as a mentor in the factory, and you will have to worry about it for the rest of your life! When the time comes, there will be a graded examination, and those with higher grades will get more wages, so that they will not be afraid of not studying seriously.
The next morning after the cutting machine was installed, Polu came to the construction site holding the caliper box he had made yesterday and a two-meter-long level.
The workers were already waiting here. He put down the box and waved his hand: "Everyone is here? Okay, let's get started!"
After confirming the flatness of the ground again with a level, the water tank placed aside was lifted in by a dozen people.
"! The two ends of this water tank are not level!"
Polu took his huge level ruler and got stuck. The wall of the water tank, which had been perfectly aligned by visual inspection before, was no longer level. He suddenly felt a splitting headache. He had to start correcting it again.
Unfortunately, after working hard for a long time, in the end, the edge accuracy of the pool could not be solved. Because the board wall was not hard enough, it would never be straight. The idea of using it as a base was shattered.
"Let it go, let it go! Bring me some long angle steel! I'm going to take a curve. I'm going to save the country by taking a curve, isn't it?" Polu's nose was so angry that he still couldn't succeed after trying for an hour.
Finally, the appropriated angle steel and brackets were erected on the two long sides, and the racks and tracks were welded. The transverse track trolley and the cutting machine module that had been installed together were placed on the track. A machine that looks and remembers
A very similar gantry cutting machine finally appeared in the open space in front of the nearby stockyard.
After another painful debugging, I encountered the next problem:
He forgot that the crystal hard wire tube used to transmit magic power cannot move freely with the mechanism. There is no problem when it is fixed, and he doesn't care if it is cut into small sizes by hand, but now he needs to cut large-sized steel plates, and he cannot use large-sized ones.
Should the workpiece chase the cutter head?
"Ah!" The angry Bolu almost broke the steel casing in his hand. "I thought it would be finished soon! But it turned out that this is just the beginning of the next problem!"
But there was no other way, work still had to be done, and after venting his anger, he obediently returned to the workroom.
"Such a familiar feeling! Why do I feel like I was just a social beast before and after I traveled through time?"
At this time he saw the copper wire in the hands of his little apprentices.
"There is something different. At least I have strong men at my disposal!" He comforted himself.
"Everyone, I have a glorious and arduous task to give you today! You need to use the fastest and best work attitude to complete it. Then, let me explain to you the specific work steps."
That night, Polu looked at the young apprentices staggering around in the studio with numb eyes. He felt sincerely happy. He walked out the door with a copper cable as thick as the mouth of a cup on his shoulders.
By the time everything was installed and running normally, it was already the morning of the next day.
In front of the onlookers, Polu personally shook the stepping wheel, cut a circle and a square from the steel plate with painted lines, and then cut a hand-width part from a two-meter-long steel plate.
When the water vapor in front of them dissipated and the water surface calmed down, several workers touched the water tank: "Little manager, it's not bad. It's a little warm, not hot." A bold worker touched the water surface and then put his hand on it.
When he reached the workpiece in the water, he paused for a moment and directly grabbed one end of the steel plate.
"Don't use your hands!!"
"It's done!"
"It's done? Let me measure it! Wait, don't use your hands when picking up the workpiece. What if the handle is burnt?"
Bolu walked up, took out a caliper, and measured the results back and forth. They were not very consistent, but the difference was about 1 millimeter. He then looked at the quality of the cut edges. Compared with the dog-gnawing precision of the steel plate that was dug out with a chisel.
, it can be said to be a huge span from the primitive people who just learned to use fire to the industrial revolution.
It had been several days since he had gone back, and Polu, who was so exhausted, almost couldn't hold back the tears in his eyes.
"It's so hard for me!"
"How's it going? How's it going, little manager?" The equally exhausted workers looked at Bolu with expectation, and Bolu nodded. He said in an almost choked tone: "Success!"
There was a burst of cheers at the scene! There were people from Boru, some manufacturing workers, and those who came to watch. They had already suffered enough. The worker who was responsible for digging out steel bars from the hot red steel plate with a chisel shouted
