"Root, take a break." At two o'clock in the morning, Foreman Qi couldn't sleep, patrolled the lathe department, and found Liu Gen, who was still inspecting the machine tool.

Liu Gen raised his head, and after seeing that it was Foreman Qi, he shook his head and said, "Qi Gong, I'm not tired yet, when I'm tired, I'll go to rest." ”

While speaking, Liu Gen continued to check the machine tool in front of him, and there were no big problems with the machine tool, but there were some minor problems. Most of the machine tools in the lathe department are relatively old, which is considered to be old, but they are prone to various problems. What's more, in order to ensure work efficiency, the machine tools in the lathe department have almost never stopped, unless there is no way, otherwise the lathe department will not let the machine tool stop at all.

Checking the machine tool in front of him, Liu Gen's was not wrinkled, and he successfully solved some small problems found. But Liu Gen listened to the sound of the machine tool working, but he felt that something was wrong, and there was a certain abnormality in it.

The slightly dim light of the electric lamp sprinkled in the lathe department, with the light brought by the electric lamp, Liu Gen lay on the machine tool, and the light brought by the electric lamp was somewhat insufficient. Lying on the machine tool, Liu Gen carefully observed the machine tool, searching for possible problems in the machine tool inch by inch. Soon, Liu Gen discovered that there was a problem with the screw rod of a fixed part on the machine tool and needed to be replaced.

Foreman Qi looked at Liu Gen, who was carefully inspecting the machine tool, and asked, "How is it?" Found the problem? ”

Unlike Liu Gen, Foreman Qi has a lot of work experience, and after listening carefully to the sound of the machine tool working, he knows that there are certain problems with this machine tool. It's just that in the eyes of Foreman Qi, it is just a small problem, and if Liu Gen can solve it, he will naturally not need to make a move.

"It's a problem with the screw rod that needs to be replaced." Liu Gen replied.

After coming into contact with the machine tool, Liu Gen found that his previous understanding of the machine tool was nothing at all, such as simple screws. The screws used in the machine tool are screw rods, that is, mechanical screws, which are flat at the front end, with a small pitch and uniform pitch. Most of the screws on weekdays are screws, and screws are also called wooden screws, with a pointed end in the front section and a large pitch.

If it weren't for the contact with the machine tool, Liu Gen's impression of the screw would probably stay on the screw forever.

Most of the machine screws are used to fasten metal subs, machine parts, and in arsenals, there are not many machine screws. There is no way, who left the arsenal without a machine specifically capable of producing machine screws? Except for some mechanical screws obtained from the Kuomintang region, most of the rest of the screws were polished by the skilled workers of the arsenal themselves.

The screws polished by the workers could not meet the standard produced by the machine, but for the arsenal that lacked screws, the screws polished by the workers by hand were sufficient. At least with these screws, it can somewhat relieve the pressure on some arsenals.

"There are not many mechanical screws in our arsenal, to see if this problematic screw can continue to be used, if it can be used, it is better not to replace it for the time being." Foreman Qi looked at Liu Gen and said helplessly.

When he knew that there was a problem with a mechanical screw, Foreman Qi was a little helpless, the mechanical screw was nothing in the national control area, but in the Huangyadong Arsenal, it was a rare item. Unless there are enough machine screws, the machine screws on the machine tool will not be easily replaced, in order to save as many machine screws as possible.

"It should be able to be used for a while, but it can't last too long, at most for a week, and if it is more, there will be a risk of breaking," Liu Gen said after carefully observing the mechanical screw.

Foreman Qi nodded, and if he was able to hold on for a week, then it would be enough. Wait until a week later, and then replace the machine screw, not to mention, the problem of the machine screw, did not have much impact on the work efficiency of the machine tool.

Of course, if you can directly replace it with a new machine screw, it will definitely improve the efficiency of the machine tool to a certain extent, even if it is very small, but it is still an improvement.

"Okay, Genzi, you can go and rest too, and you have to continue working during the day." Foreman Qi patted Liu Gen's shoulder and spoke.

Liu Gen nodded, at this time, it is indeed necessary to rest. Back at his place in the lathe department, it was a little shabby, with only a pair of quilts and toiletries. After a simple wash, Liu Gen lay on the bed.

There was a problem with the mechanical screws on the machine tool, but there was no way to solve it, and Liu Gen felt that there were still many things he needed to do. There is no equipment for manufacturing screws in the arsenal, and when screws are needed, they can only be purchased from the National Control Area, and it is impossible to buy mechanical screws in the Japanese Control Area, and the devils are very strict with the management of this kind of thing.

Even simple machine screws need to be polished by hand, and it is conceivable that the industrial base of the Eighth Route Army is poor.

However, Liu Gen also knew that the headquarters of the Eighth Route Army was also well aware of its own situation and focused part of its energy on the development of industry. The front line needs to fight with the devils, and there are many areas that need to be developed in the rear, and the Eighth Route Army is under great pressure.

But everyone knows that such pressure is inevitable, even if the pressure is great, it cannot stop its own industrial development.

Open the prestige mall, after Liu Gen thought about it carefully, he chose to exchange the drawings of the two machine tools, because the drawings he exchanged belonged to the relatively backward kind, the prestige consumed was not much, and it only added up to ten points.

The physique of the two machine tools is only ten prestige points in total, Liu Gen is a little dissatisfied, can it be said that the drawings of these two machine tools can only be compared with the big steamed bread manufacturing technology? Even if these two machine tools are much behind the outside world, they are not so cheap, right?

Liu Gen was not stupid enough to protest against the system, it was good to be cheap, so that he could exchange some more drawings. If you are a little behind, you will be behind, and in the case of the arsenal, too advanced machine tools cannot be manufactured.

Besides, most of the machine tools in the arsenal are powered by steam, if Liu Gen gets an electric machine tool, then it will not be of any use at all, and the arsenal can't afford such a big guy.

Finding some paper, Liu Gen drew the drawings of the two machine tools he had exchanged, which were a little behind, but they were enough for the arsenal. Liu Gen's speed of drawing drawings was not very fast, and by the time he fell asleep, the drawings were only half completed.

Put the drawings at the head of his bed, this is where Liu Gen rests, few people come here, and even if they come, they will not easily touch Liu Gen's things. The drawings of the two machine tools have not been drawn, and the relevant data have not been marked, so if they are really taken away by others, Liu Gen will not feel distressed.

Without relevant data, even if Liu Gen drew all the drawings, it would not have much effect.
