It's really unpredictable, Gu Fei just wanted to get a good knife, but he dug out a batch of rotten knives.

Private companies will naturally prefer to kill mistakes and not let go of this kind of thing. The logistics department did not dare to hide it, so they hurriedly sealed the knives and began to report layer by layer. However, how to deal with this is not something that Gu Fei, a temporary worker, needs to worry about.

Gu Fei was a little depressed.

Those new knives are hard to use, but that doesn't mean they can't be used.

For example, if a 125-piece knife can be used for 100 hours, then a 30-piece knife can be used for at least 10 hours.

It's just that the knife has been sealed, and Gu Fei doesn't even have this kind of knife that can be used for ten hours now. He had no choice but to return to the manufacturing workshop in despair.

However, there is no new knife to make a smooth knife, so you can find a relatively good old knife to replace, but you have to sacrifice the surface roughness or finish.

Of course, you can also sharpen knives, and some gods can sharpen old knives as sharp as new knives, or even surpass new knives.

But sharpening knives is a real kung fu. Many masters who have played lathes or milling machines for N years are helpless against this.

Many people sharpen their knives either miserably or the machines will protest when they are used, so for the time being, it is not something that Gu Fei, a newcomer, can eat in one bite. Even if he had such a magical laboratory as No. 1.

Having said that, there are good knives in the No. 1 material vault that can be taken, but Gu Fei will not take those things that belong to him and put them here to trample on.

He had to go to the master of an ordinary lathe.

There are a lot of ordinary lathes and general milling in the manufacturing workshop on the first floor, which is located not far from the number of lathes, and of course there are many general lathes and general milling masters working.

This may be the difference between CNC and ordinary machine tools.

As long as one or two masters adjust the machine tool, the CNC machine can bring up a whole piece of machine, which is extremely efficient and of better quality. The ordinary machine tool can only be opened by one person, not to mention the low efficiency, the labor is heavy, and the quality is difficult to control. So now in the manufacturing industry, more and more CNC machine tools have replaced ordinary machine tools.

Sharpening a knife is difficult for some people, but it is easy for others, so Gu Fei finally got one from a certain master.

The word "begging" was not an exaggeration at all, Gu Fei's mouth was about to smoke, and someone reluctantly squinted his eyes and gave him a handful.

He asked No. 1 to look at it, and No. 1 directly replied with three words: "Yes." ”

Gu Fei held his breath and had to leave thankfully.

When you work hard, time flies. Check the machine, enter the program, load the knife, set the knife, write the parameters, and finally finish it, and get off work.

A bunch of men who were lazy and carrying things came over and asked him with a grin: "College student, I see that you have been busy all day, are you adjusting the machine, when can you get a machine right?"

They said depressedly, "If this continues, we will all be put on vacation." ”

"Tomorrow. Gu Fei replied calmly, and he added again: "You don't have to worry about not working, go back and have a good rest." Isn't there a whole bunch of molds and scrap to move over there?"

A bunch of men have crooked mouths.

Not having a job at work may sound comfortable, but it's actually quite painful to stay up for eight or ten hours. But comparatively speaking, it is more painful to move those dead molds.

Although he is a temporary worker, the company also has a meal that belongs to Gu Fei. It is said that the collective meal of the school or company is unpalatable, and the premise is that there is food to eat, so Gu Fei eats deliciously, and feels that the world is only delicious.

He went back to school and looked around. Because of the summer vacation, the whole school was dead and empty. He ignored the door of the dormitory and went straight to Lab 1.

"One, I'm going to learn how to sharpen knives. Gu Fei shouted towards the ceiling.

It's just a car knife, but he's fed up with the bird's anger of the bunch of ordinary car masters today. It's better to ask for someone than to ask for it, anyway, sooner or later you have to learn, just hurry up and start immediately.

“OK。 No. 1 responded coolly, and a grinder and a universal sharpener instantly appeared not far away.

"Do you want to learn simple sharpening, or do you want to learn complicated?" said One.

Gu Fei was stunned and asked, "This also depends on the situation, what is simple, and what is complicated?"

"It's as simple as giving you a lightly worn knife and getting it sharpened again. The complicated ones are quite perverted. For example, you are directly given a steel rod with a diameter of 30, and you are first asked to sharpen it into a blade with a diameter of 15, then groove it, and then cut the blade...... All the way to sharpening into a good knife. ”

"That kind of power?" Gu Fei asked curiously.

"There's nothing that doesn't give up. The tool is ground out for processing, and it is good to grind it until it can be used. However, the grinding method behind can be installed with X in front of outsiders, ensuring that anyone will be stunned when they see it. ”

"Then I'll learn the next one. Gu Fei smiled. He seemed to have seen himself take out an iron rod and sharpen it with a brush.

No. 1 was silent for a while and said, "I haven't finished speaking, others will not only be stunned when they see the knife sharpening method behind them, but they will also secretly scold you SB." ”

It explains: "This method of sharpening knives is basically of no practical significance. Usually one is that companies don't like a certain candidate and can't say it directly, so they use it to embarrass him. ”

Gu Fei couldn't help but lean in, he thought about it for a while, and asked: "Although it has no practical significance, but after learning the knife sharpening method in the back, there must be no problem if you want to sharpen the small residual knives in front." ”

"This is natural. No. 1 replied lightly: "If you grind a knife stick directly into a tool, then he is a five-axis machining center, you can grind it, you should understand what this means?"

Gu Fei's eyes lit up, and he couldn't help but be moved, and he replied directly: "Then I'll learn the sharpening knife in front first, deal with the future work, and then slowly learn the methods in the back." ”

No. 1 didn't say anything more, a knife sharpening video popped up directly, and Gu Fei quickly learned seriously.

After reading it again, Gu Fei asked some things he didn't understand, looked at it again, asked some questions, and after repeating it a few times, Gu Fei began to sharpen his knife.

From time to time he would stop, watch the video for a while, think about it, and grind it again.

A few hours later, Gu Fei, who was standing on the edge of the knife sharpener, was full of exhaustion. At this time, his whole body was covered with a thick layer of ash, and he didn't know how many knives he had changed on his hands, which had completely lost his skin. Even the grinding wheel was worn out and directly replaced with one one.

"If you're tired, take a break. Gu Fei found a place to sit down.

A gust of wind blew, and Gu Fei, who had just sat down, immediately became clean and clean, which made him sigh with amazement.

"Don't rush, take your time. Every time you grind a few times, you have to think clearly in your mind about what you should do, and you have to count what you should grind into in your heart. ”

Gu Fei nodded, rested for a while, and immediately got up and walked towards the knife sharpener.

Number One watched silently, not making a sound.

Only those who have tasted the pressure of survival can understand and understand why Gu Fei persists, even if he grits his teeth and does not give up no matter how hard and tired he is.

After a few more hours, Number One said, "This knife can be used for rough cutting, but it won't take long for it to collapse, the tip of the knife is too sharp." ”

Gu Fei nodded, stared at the tip of the knife fixedly for a long time, and then continued.

"This time it's good, but it can only be used to open rough, and the blade is not sharpened. ”

The so-called rough opening is the process of processing the blank for the first time and gnawing off the remaining material as directly as possible with a rough knife. These knives are naturally not too good, and if they are too good, they are wasted. But it can't be too bad, otherwise the tool will break directly.

After a few more hours, No. 1 said, "Yes, it can be used on the medium-light." Fix the front blade again. ”

After a few more hours, Number One sighed with emotion: "Very good, in the absence of a new knife, this knife can barely be used as a bare knife." ”

Gu Fei finally let out a sigh when he heard this, he struggled to crawl out of the laboratory, took a shower, and fell asleep directly with his head upside down.
