Mecha and Knife

Ji Xinghe is actually not as confident as he said. After reading the list of maintenance requirements in the 109 operating area again, he found that there are not many things he can repair. As Master Liu said, he should study for at least one year in mecha maintenance, to be really familiar with mecha maintenance operations, and to understand all the standard mechas of the Federation. After all, mecha maintenance and car maintenance are completely two concepts.

Or as Shen Mu said, join an operation section, use every opportunity and time to eagerly learn from others when repairing parts that you can repair, even if others have no time to guide him, with his forty years He can learn a lot from the experience and various professional skills in auto repair and maintenance, just by watching others repair.

But it's like Master Liu didn't hire him to join the No. 109 operation section in the first place when he knew he was an eighth-level fitter. Like everyone else, he knew that he was old and he didn't have so many It's time to study normally.

"Ji Xinghe, you have to do everything you can do, do these well and then talk about other things."

Ji Xinghe said this to himself in his heart, and then he started to repair the energy transmission board. He was not confident in mecha maintenance, but he was confident in his physical fitness and energy, as well as the ability of an eighth-level fitter and more than forty years of work. The experience he brought, as well as the physical fitness, stability and precision of eyes and hands brought by practicing martial arts since the fifth grade of elementary school.

The energy transmission board is a product of the new era. A concise summary is wires. There are very few lines similar to wires in the federal restraining mechs of the new era. Whether it is the transfer of energy or the transmission of information and data, they use An energy transmission plate made of exotic metals.

You only need to carve lines on it, and energy or data will pass through the lines. The transmission efficiency and stability are higher than traditional lines, and there will be no conflict with the connected metal parts. If there is damage, replacing the energy transmission board is much faster than replacing the wiring system, and it is easier to find the specific damaged part, just observe the lines on the energy transmission board.

Before coming to Alien Star, Ji Xinghe knew the energy transmission board, but he didn't know the inscription route of those lines, but he still chose to repair the energy transmission board, because he has the corresponding authority and can see all the federal system machines A 'circuit diagram'.

The next thing is very difficult for others, but it is relatively much easier for him. In his words to Master Liu, it is like drawing a scoop from a gourd.

When a slender energy transmission plate was picked up by Ji Xinghe, it was directly deformed by some soft steps. It was not secondary damage but its own flexibility was very good, just like a soft sword. Putting it flat on the workbench, Ji Xinghe took a special magnifying glass and began to observe the lines on it, and looked at the screen on his bracelet from time to time.

Comparing the two, it is easy to find the damaged place, and then it is necessary to determine whether the damaged lines can be re-engraved. If it is possible, then start directly and repair within the maximum error of 0.05. If it cannot be re-engraved, then all the lines on the energy transmission board need to be polished off, and then re-engraved within a maximum error of 0.02 or even 0.01.

The allowable error becomes smaller, and the difficulty becomes much larger. The maximum error of 0.01 mm is a maintenance item that many people in the mecha area are unwilling to get started. If they are not careful, damage will occur, and then they can only Throwing it to the robotic arm that needs to be queued is better than throwing it directly to the robotic arm from the beginning.

It cannot be returned to the furnace for remanufacturing. There is only one chance to smelt this special metal from mineral to metal form. Artificial intelligence program computing resources, robotic arms, etc. have all been used on it.

Ji Xinghe was under a lot of pressure, but when he started maintenance, his breathing, hands, and eyes were very stable. The carving knife in his hand seemed to be motionless along the lines projected by the laser caliper under the fixed special magnifying glass. But it is actually moving all the time, so new, effective textures are generated.

After a board was repaired, Ji Xinghe did not stop to rest. His energy and physical fitness are really good, otherwise it would be impossible to run 10 kilometers in 35 minutes. For other old men of the same age, even those about fifteen years younger than him, let alone thirty-five minutes, they may not be able to run ten kilometers in an hour, and they will need a stretcher to serve them even if they are struggling to finish the run.

There was a problem with the maintenance of the second board, not Ji Xinghe's problem, but the re-engraved lines did not pass the inspection, which means that all the lines on the board need to be ground, and then a full set is engraved on a thinner board. texture.

So Ji Xinghe began to grind. He also has confidence in this aspect. One of the test items for the eighth-level fitter is to grind a ball. Use tools to grind an irregularly shaped metal ingot into a sphere as round as possible. The tolerance is only 0.01 mm.

It is not difficult to replace it with the technological tools in the mechanical arm and machine tool, but when it is replaced with human hands as the main body, automatic tools cannot be used in the later stage of polishing the ball, and only files, knives, etc. Tools such as carving knives are polished bit by bit.

Ji Xinghe seems to have returned to the time of the exam, but Master Liu's grandfather is no longer in the exam room, and he is not 45 years old back then, but 65 years old now. But his hands are as steady as before, his vision is as precise as before, his experience is richer than before, and his inner drive is stronger than before.

Grinding and then re-engraving all the lines, the difficulty is not only that the maximum allowable error is only 0.02 mm, and some parts are even only 0.01 mm, but that there are more lines on this board. The more the number that needs to be inscribed, the greater the possibility of making a mistake. Half a hundred miles away?

No, 90% of the inscription is not half completed, but a complete failure, a bigger failure than starting from scratch, because after the failure, if you want to polish and inscribe again, the maximum error that can be allowed is 0.005 to The degree of 0.001 mm, in Shen Mu's mouth, this is a manual precision that surpasses the limit of human beings. Even the unit of millimeter is no longer usable, and it has reached the nanometer level that only robotic arms and machine tools can achieve.

The 65-year-old Ji Xinghe is actually very suitable for such a job because he is very old. This was originally his disadvantage, but now it has become his advantage, because he will have more patience when he is older.

Just like many old men and women, they can sit in one place from dawn until dark, without playing with mobile phones, reading books or watching TV, and the scenery in their sight can even remain unchanged. But this is not because they don't need to feel external objects, nor because they have lost the ability to feel external objects, but because they can clearly feel the passage of time.

So, the repair of the second board was completed, but this time Ji Xinghe did not inspect it, just like he did not inspect the first board when the repair was completed. His inspection on the second board when the first repair was completed was simply because of his lack of experience, and now his experience and intuition tell him that he has already repaired it, so there is no need to inspect it.

The experience brought by the two boards is still too little, but it doesn't matter, there are 39 boards in the 109th operation area that need to be repaired, and there are 149 operation areas in the mech area of ​​this base, and they all have board maintenance needs.

"Ji Xinghe, do what you can do first. Mechas and cars are actually the same. It doesn't matter if it's a little more complicated. Come one by one, sooner or later you will be able to repair the mecha like a car. You can repair it like a car. It’s like making a car by yourself.”

Ji Xinghe said this to himself in his heart, and started the maintenance of the third board. What he and everyone in the mecha area did not realize was that his maintenance speed was getting faster and faster.
