Return to the exciting era of 1999

Chapter 50 Mastering the core is mastering the initiative
"It's enough, the bigger the brain, the dirtier the brain! A blank sheet of paper is the best, come over here, I'll teach you how to write materials!"

Looking at a group of students with childish faces, Ji Donglai waved, and everyone hurriedly gathered around.

Ji Donglai began to explain from the handling of materials, how to operate the hoist crane, how to operate the equipment, and how to cooperate with colleagues.

"Have you seen it? Don't be too troublesome to set the knife! This is a CNC bed, what we need to do is to be meticulous and clear? I also set up incremental operation at the beginning of the program. Once you find out the operation and drawings different profile, let me know as soon as possible!"

"I can't rule out the possibility that my programming is wrong. Of course, it is also possible that you may have made a mistake. After all, you have to remember that no problem is the key point! The three months you come here is considered an internship period. Even if we don't give you I can accept the company making a little profit, but don't make losses!"

"Of course, what should we do if there is a loss... Our company will bear it within three months! After three months, everyone will bear it together. In short, we can do it with confidence and boldness. Those who can do it will stay, and those who can't do it will leave early! Machinery It is difficult to make a lot of money in this business, but once you learn the CNC equipment, it is not difficult to make a lot of money!"

"Now you are learning short-answer numerical control. The equipment over there is a machining center, and the processing fee is 60 yuan an hour! You can calculate how much it costs per day! So, work hard, young people!"

Ji Donglai didn't stop talking for a whole day, his voice was a little hoarse, he explained everything to this group of rookies, and he didn't forget to give them a bloodbath.

Facts have proved that it is more useful to fight chicken blood in many cases. Hearing that the processing fee is 60 yuan an hour, a bunch of rookies' eyes are shining.

The next thing is that this group of people started to practice, and Ji Donglai and Lu Shipeng went back to the waiting room.

"I didn't see it, brother, you really don't leak anything! Our factory masters are not as capable as you. My brother is really lucky to be able to cooperate with you! Drink some water..."

For a day, Lu Shipeng was inseparable, and his heart went from worrying at the beginning to admiring Ji Donglai later, and now he finally felt relieved.

According to Lu Shipeng's expectation, it would take at least half a month for these rookies to start working on the machine tool, but what Lu Shipeng didn't expect was that Ji Donglai asked these people to start working the next day.

"Donglai, can it work? This bed is expensive, it really hit..."

Looking at the clumsy operation of the machine tools by these rookies, Lu Shipeng's heart skipped a beat, especially when he saw that some rookies' knife-setting movements were like children learning to walk, Lu Shipeng felt his heart beating.

"Practice and you'll be fine. Novices will definitely have problems. It's much better to show up early than late! I saw your factory. It's too old. After a few years, many people will have difficulty adapting to the new equipment. New people have to come in. , if I’m here watching, it’s not a big problem!”

After taking a sip of soda, Ji Donglai stared at a group of rookies with good eyesight.

"You're right, brother! I'm relieved to have you here. Cheng, I'll leave it all to you. I'll send a teacher down there the day after tomorrow to keep an eye on it!"

After thinking about it, Lu Shipeng knew that what Ji Dong said was fine, and finally decided to believe Ji Donglai.

Facts have proved that what Ji Dong said is correct, young people are the strongest in accepting new things. That night, a group of students began to formally process and manufacture.

In fact, Ji Donglai has compiled the NC program, printed it out, and the students can just input it into the equipment.

The machining center can be equipped with an interface, but here it is all manual.Every time the input program is finished, Ji Donglai will check it again to confirm that there is no problem, and then Ji Donglai allows the other party to run.

"Buzz..."

"Boy, where did you work before?"

The next day, Ji Donglai's first batch of semi-finished products started to roll off the assembly line. Ji Donglai directly sent the first batch of students to the processing center, and a group of students from Kaimeng also began to process the products.

Li Chunhe entered Ji Donglai's workshop with leaf cigarettes in his mouth, seeing Ji Donglai's appearance as a master, and then came over.

"I did it in Hebei... you guys, pay attention to safety, the suction cup is clamped, wipe the surface of the workpiece clean and then clamp it, don't worry about it, understand?"

Seeing the students trying to pick up the wet semi-finished products, Ji Donglai yelled loudly, and the students hurriedly made an apologetic gesture to Ji Donglai.

In the eyes of this group of people, Ji Donglai was about the same age as himself, and it was very easy to communicate with him, but his heart was just awe-induced fear.

"Guys, can you let this group of students program? People who study these days are nerds, and there are not many who can write useful programs. Besides, people who study have a lot of eyes..."

Li Chunhe put his hands in his pockets, looking at the young faces in front of him, his eyes were full of disapproval.

Ji Donglai didn't answer, but went to a machine to check briefly, and directly pressed the emergency stop button.

"Check it, the workpiece is not clamped, and the surface of the workpiece is not clean, it is very dangerous, the monitor will come over and check it!"

Ji Donglai pointed to the clamping part of the workpiece and said loudly to the students. The other party looked carefully at the part but did not see it. Ji Donglai directly greeted the other party's team leader who came to practice.

"boom!"

"Look at the second claw, I told you to wipe it clean several times, have you wiped it?"

The team leader saw the iron filings on the workpiece at once, and hurriedly helped unload the workpiece. The faces of the students who were operating turned pale with fright.

"It's okay, be more careful next time! Remember to align the knife again. Remember, the machine is a dead thing! He can only work according to the instructions you gave him, and we must follow the rules! We must strictly follow the rules. Follow the dead rules! Otherwise, the things we process will be crooked, and the equipment will have traces on the surface of the equipment in the future!"

"Everything is difficult at the beginning, it doesn't matter if you slow down, you must understand the principle thoroughly?"

Ji Donglai pressed an iron plate and sandwiched another iron column in the middle, explained carefully to the student who made a mistake why he did this, and made the other party pay attention.

Knowing the principle, the other party will naturally know the key points of the work when they work.

"Thank you, teacher, I understand! Four claws, this point clamps less, the workpiece is off-center, the concentricity of the processed is not good, and the misalignment of two parts will cause big problems!"

The principle was thoroughly explained by Ji Donglai, and the students kept nodding their heads.

"It's not just like this, do you understand? There is a center inside the CNC machine tool, and the center inside the cutter head is coincident by default. You cheated by clamping. Once the tool setting is not accurate, the default of the machine tool is still the original center point. Up is useless!"
