Chapter 6 Section 6

After finishing the day's work, the man finally appeared when he was about to turn off the main switch.I don't know where and when he came in, so when he said "excuse me", Maejima was so scared that his heart almost stopped beating. The man stands on the inside of the shutter.Tall and bespectacled, he resembled a spindly cartoon character.But after looking carefully, it can be found that his shoulders are actually quite broad and strong, and well-developed muscles are exposed from the sleeves of his jacket. Maejima didn't ask what's the matter, but looked him up and down with vigilant eyes, and then nodded as a signal.The man nodded upon seeing this.

This is the first time a stranger has come to this factory.This is a small street factory with only three people including the owner.Today, because the factory manager wanted to discuss business with an old customer, he went out early, and his only colleague also passed away due to a cold. I heard that you can process precision devices here, so I want to ask you to do a job. "The man's voice was cold and emotionless, which made people feel a little scared. How to do it?Maejima thought, how to deal with such customers who come directly to the door?He couldn't get a clue for a moment.

Since he didn't respond, the man also stood there staring at him.He felt that if he didn't answer anything, the man would not leave. Maejima had no choice but to take out his work diary, wrote "I am dumb and can't speak" on today's page and handed it to the man.However, the man did not comment on this, and said with his expression unchanged: "I plan to place an official order in a few days. But before I want to confirm whether you can do what I asked. In fact, the processed Is it you?" Maejima nodded and pointed at himself, then held up two fingers. "Ah, you mean there's one more person? As long as you're here, it's fine. Well, can I see your processing equipment here?"

Maejima nodded, because he had seen the factory manager and showed customers around these machines, and even if he saw them, there would be no trouble. The man walked slowly to the machine next to him. "Well, the two electrical discharge machines and the two wire cutting machines are all produced by M Company, and most of them still have national standard certificates." Hearing what he said, Maeshima hurriedly wrote something in his diary and got it in front of Nanyu. The man read it out: "Because the machine is very old, it cannot perform complex processing." - wrote in the diary.

The man smiled slightly, perhaps because he thought his modesty of deliberately refusing was ridiculous. But from Maejima's point of view, it's not a bad thing to settle these things in advance, and it's the actual processing workers like himself who are in trouble in the end.Tokita Processing Station is the name of this street factory, and it goes without saying that Tokita is the name of the factory manager.All the equipment in the factory is cheaply purchased by Factory Manager Tokita from the heavy machinery factory where he worked, and they have already exceeded their useful life. Everyone in the field processing station regards it as a treasure.

"Is the wire 0.4 mm?" the man asked while squinting at the working cable cutter. Maejima nodded, surprised that this man was so knowledgeable. A wire cutter is a bow saw that uses electrical energy.The wire cutting machine can fuse the workpiece by using the tiny discharge current generated in the circuit.Because the discharge current can be concentrated, the processing accuracy can be as accurate as microns. "Can it be processed like this? Can it be done?" The man pounded out a piece of paper from his jacket pocket.On that graph paper, the shape of the part was drawn with complex curves.Judging from the notes and instructions on machining precision, this man is definitely not an amateur.

Looking at the drawings, Maeshima thought, this is really a precise part, especially the processing of the corners and corners, the requirements are too strict.In order to express this meaning, he tilted his head and pointed to that part of the drawing with his finger. "It's indeed more complicated there. If you can't do it, you can reach as far as you can. Just do your best." The man looked around carefully along the wall, and suddenly found the parts on the shelf tray.He held a part in his hand and looked at it carefully.It was a sample of a custom auto part from a certain company.

Maeshima pointed at the shelf tray, made a gesture of touching it with his hands, and then put his hands in a fork shape in front of his chest.Seeing this, the man immediately understood what he wanted to say. "I'm sorry, I'm so rude. It's forbidden to touch metal products with your hands. The salt on your hands will cause the parts to rust, right?" The man hurriedly put the parts back in place. "How is it? Can I ask you to help with processing?" Maejima pointed to several parts on the drawing, and then used his thumb and index finger to draw a distance of about 3 cm in front of his eyes.

"Ah, that's really the case. Perhaps the relaxation of the requirements on these places can still be processed. Is that what you mean?" The man made an expected expression and nodded at the same time. "Okay, I'll take the blueprint back today, and I'll bring it to you when it's corrected tomorrow." Maejima nodded and handed the blueprint to the man. But the man did not leave immediately after receiving the blueprint, but kept staring at the gas cylinder standing by the wall.There are many kinds of gases stored there. "Actually, there is one more thing I want to ask you." Perhaps because he noticed Maeshima's gaze, the man raised his index finger and said.

Maeshima leaned forward and listened carefully. The man said, "My question may be a bit strange. Has there been any special phenomenon produced by using this electrical discharge machine or circuit cutter?" It was such a strange question that all Maeshima could do was shake his head blankly. "That is," the man said, waving his right hand, "will there be a plasma phenomenon or something?" Maejima's eyes widened in surprise. "There is a close connection between the discharge phenomenon and the plasma phenomenon, so I ask you such a question."

Maeshima wrote in the original diary again: "Is it about the accident on Flower Shop Road?" Then he showed it to the man. "Ah, that's right." The man smiled wryly, then put his hand into his jacket pocket, and took out a business card from it. "This is my business card. I discussed that case with Peng Fa." The business card showed that the man was an associate professor of physics at a prestigious university.Maejima felt a little nervous. "Therefore, when I asked someone to do the processing, I asked some questions by the way. I think this may be a little reference for us." Maeshima nodded, and wrote the following in his diary: "There has never been anything like that." "Does this mean that there has been no plasma phenomenon?" Maejima nodded vigorously. "That's it." The man's expression was slightly disappointed. Maejima wrote the following text again: "Is it really plasma?" "We think so, but conclusive evidence is lacking right now." Maejima shook his head and thought, what is going on? "Plasma has the property of being easy to reappear on the same occasion, so if the same phenomenon can still occur near there, then it must be it." The man said while knocking on the top of the gas storage room.After speaking, Maejima said, "I'm sorry to disturb your work. I'll come back after I re-study this issue of machining precision." "Waiting for your visit." Maeshima lowered his head with such a mood.It was nice for a man to be able to treat himself like a normal human being. The associate professor of physics at the university raised a hand, pushed open the door next to the shutter, and left.
