Chapter 48 The advent of CNC machine tools

This morning, as soon as he arrived at the steel rolling mill, Yu Wei was called to Director Yang's office on the third floor.

"Yu Gong, sit down, sit down, sit down." Director Yang stood up and asked Yu Wei to sit down. Then Secretary Li brought a cup of tea, put it down, closed the door and went out.

"Yu Gong, you may have to work harder in the next period of time! The CNC machine tools developed by several departments last time are already in sight!" Director Yang continued.

"Every aspect is almost ready. Mechanical, hydraulic, circuits, etc. are all manufactured according to the design you provided last time. Another department has also developed the control part. Now we are waiting for the final assembly and debugging!"

"Yesterday afternoon I went to the ministry for a meeting. When I was leaving, the senior leader grabbed me and asked me to arrange this matter. Let you go directly to the CNC machine tool R&D team in the next period of time to participate in the final assembly and debugging of the CNC machine tool."

"You can leave it here at the steel rolling mill first. Before this project is completed, you don't need to come over to the steel rolling mill to order. I will inform the personnel department in the factory. Just go directly to the CNC machine tool project team every day!" Yang

The factory director said again.

Then he handed a note to Yu Wei and said: "This is the address of the R&D team that the leader asked me to forward to you. Also, remember the confidentiality regulations. Before the CNC machine tool is successfully developed, absolute confidentiality is required."

After that, he found a document bag from the drawer and gave it to Yu Wei: "Here are your ID and access certificate for the R&D team. You should carry it with you so that you can review and enter and leave the R&D team at any time." Director Yang

Said again.

Yu Wei took the document bag, opened it and looked at it. There were some certification documents inside. One of them said the entry and exit voucher for a certain department. There was a small photo that Yu Wei had submitted before, which said Yu Wei, a certain department, and his professional title.

Level 5 Engineer! Hey, when did you get promoted to a level again?

Yu Wei pointed to his professional title and said to Director Yang: "Is this written wrong? When did I become a fifth-level engineer?"

"That's right, the ministry has directly rated you a fifth-level engineer this time. The monthly salary is 178 yuan, and the factory will give you a monthly subsidy of 22 yuan. From now on, you will receive exactly 200 yuan per month. The factory will inform you in the afternoon.

"Director Yang said.

"Starting tomorrow, go to the CNC machine tool R&D team. Take a good rest today!" Director Yang said again.

In the evening, the family sat together and chatted while eating. Yu Wei told everyone that he had been rated as a fifth-level engineer. He immediately received the adoring eyes of Yu Haitang and the stars in Yu Li's eyes.

Father Yu and Mother Yu are also very happy! These days, level five engineers are the upper limit for technical engineers in steel rolling mills.

The next day, Yu Wei rode the tricycle directly to the R&D team. Speaking of tricycles, the machinery branch is really standing on its butt like a heifer now, it’s getting awesome!

Due to the practicality and flexibility of small three-wheelers, through certain aspects of regulation, priority is given to rural production teams, brigades, communes, townships, and towns. In big cities, like Sijiucheng, it is difficult to get a ticket.

Hard to find.

Now the machinery branch is expanding again and again, but it can only meet a small part of the demand. Especially after the external sales through Xiangjiang China Resources Company, orders from third world countries are coming in a steady stream!

In this case, foreign exchange creation is a priority, and if you are in the city, you have to be put in the back queue. Let’s not mention this matter for now.

It is only said that Yu Wei left Sijiu City based on the address provided by Director Yang and found a factory called Xiangyang Machinery Factory in the northern suburbs. After the factory guard checked Yu Wei's ID, he asked Yu Wei to wait for a while.

.

Then the guard entered the guard room, shook the phone, said a few words, and when he came out, he told Yu Wei that someone would come out and take him in later, and asked him to wait a little longer.

After a while, Yu Wei saw a certain expert who he had seen in the big leader's conference room last time and had dinner with the big leader. Yu Wei remembered that this expert's surname was Hu.

When Expert Hu saw Yu Wei from a distance, he happily walked two steps faster and rushed over. When he came to Yu Wei, he happily said to Wei: "Yu Gong, I've finally waited for you! I'm waiting for you!"

After that, he shook Yu Wei’s hand hard again!

"Follow me. I will come to pick you up today. From now on, you can come and go freely with the certificate issued to you!" Expert Hu said.

"Okay, thank you Hu Gong!" Yu Wei thanked him quickly.

Expert Hu took Yu Wei through the corridor on the right side of the first floor of the office building. At the innermost part of the corridor, there was an iron door. Expert Hu took out the key and opened it directly. While opening the door, he said to Wei, "Someone will find this key later."

Give one to Yu Wei and then use the key to unlock it directly.

After Expert Hu opened the door, he took Yu Wei down another section of the corridor. At the innermost part of the corridor, there was another iron door, which should be opened with another key. Expert Hu said to Wei that the key here would be issued to him later.

he.

After the door opened, Expert Hu led Yu Wei into a fully enclosed workshop of about 600 square meters.

There were quite a few people inside, and Yu Wei saw at a glance that there were seven or eight people who would become academicians in later generations, and he had read their biographies.

There is even one of them who is an absolute master of computers in later generations!

Here, Secretary Lin, the secretary of the big leader, served as the logistics coordinator. The R&D team leader was Expert Xu from the mechanical department, and there were two deputy team leaders, one of whom was the later computer giant and Expert Hu.

Yu Wei was assigned the task of being the general commander of the final assembly and the leader of the debugging team. In other words, Yu Wei came to assemble the CNC machine tools and was responsible for debugging after final assembly.

After everyone gathered, everyone stopped talking and carefully checked the assembly parts of the CNC machine tool and the parts waiting for final assembly!

Then Yu Wei checked the design drawings again! After confirming that they were correct, the final assembly began.

During the final assembly process, Yu Wei constantly checked whether the tolerances of each component were within the allowable design range. For components whose tolerances exceeded the design range of the drawing, they were immediately stopped and re-processed and produced according to the tolerance requirements on the drawing.

In this way, the speed of final assembly will definitely not be fast, but if the requirements are stricter, the success rate will be higher later.

Of course, this cannot be achieved overnight. Before leaving get off work in the afternoon, Secretary Lin handed out keys and other items to Yu Wei. Today was just the beginning, and things had to be done step by step.

Yu Wei spent the next half month or so every day like this. Early this morning, the members of the R&D team gathered in the workshop.

According to the progress made in this half month, the CNC machine tool will be completely assembled today!

Yu Wei was also very excited!

Keeping his mind steady, Yu Wei loudly issued various instructions for the final assembly, and the personnel at each station in the workshop also carried out their work in an orderly manner.

Finally, Yu Wei shouted to check whether the final assembly was completed. After waiting for a while, everything was reported to be completed normally.

Yu Wei checked again and found no problems, then shouted: "Power on!"

Then the switch was turned on and the CNC machine tool was connected to the power supply. Then Yu Wei pressed the start button of the CNC machine tool!

Suddenly, the sound of the engine and oil pump rotating came from the CNC machine tool. Then Yu Wei began to test the various movements of the CNC machine tool with the machine empty.

After all the tests were completed, Yu Wei was extremely excited. All aspects of the CNC machine tool had met the design requirements. Now all that was left was trial production to see how the control part performed.

The test results of the mechanical part and hydraulic oil circuit designed by Yu Wei are very satisfactory. Now only the machine tool control part is left to see if it can meet the design requirements! This part is the top priority of the CNC machine tool!

Yu Wei has completed his task and is now gathered with everyone, watching the workers load the workpieces and clamp them with clamps!

Then the computer guru was inputting various data and instructions into the CNC machine tool. After completion, Yu Wei saw that he checked it several times and then pressed the start button.

Next, it’s time to wait. Everyone stares at the CNC machine tool processing the workpiece without blinking.

Later, after the workpiece was processed, the R&D team leader and others hurriedly conducted various tests on the workpiece!

After the test results came out, everyone tested again, and the results were still the same. The R&D team leader announced that the machining accuracy met the design requirements of CNC machine tools!

Everyone hugged each other happily! Then, they repeated the CNC machine tool several times and conducted various tests. By the time they got off work in the afternoon, the R&D team leader finally announced that the CNC machine tool had been successfully developed and its performance was the same as similar international products!

Secretary Lin immediately organized everyone and held a simple celebration first. The details will be decided after all the situation is reported to the superior.

Yu Wei also completed his mission. After everyone briefly celebrated, Yu Wei handed back various keys, passes, etc., and said goodbye to go home.

After returning home, Yu Li had gone to bed and went to sleep first. Yu Wei quickly washed up and went to bed and fell asleep.

CNC machine tools were developed, and Yu Wei also breathed a sigh of relief. There are still a few years to reach the ten-year period. As long as CNC machine tools are developed well in the past few years, even if CNC machine tool technology stagnates in those ten years, then CNC machine tool technology will stagnate.

It’s much better than the previous life!

Yu Wei breathed a sigh of relief and slept until dawn. After getting up, Yu Li saw that he looked relaxed and knew that Yu Wei had been busy recently and should have completed the things that he had not mentioned at home.

Then he stepped forward and hugged Yu Wei and said: "I have been busy for so long and I am finally done? Is it going well?"

Yu Wei took the opportunity to take a bite of Yu Li and said: "Well, it went very smoothly and successfully, but I can only tell you when I have the opportunity in the future."

Yu Li knew that some things about Yu Wei's work were required to be kept confidential, but she didn't care. She just said: "If you can't say anything, you'd better not say it!"

Then I talked with Yu Wei about Yu Haitang's decision not to enter college. Yu Haitang's grades were not comparable to those of Yu Wei and Yu Li. Two college students at home took turns tutoring her, but they still couldn't get into college.

Yu Wei couldn't help it, so he said to Li: "We are both college students, and the jobs assigned after graduation will not occupy the jobs left by my parents. I will talk to Factory Manager Yang and Director Gong of the Human Resources Department then.

Just give one of the jobs to Haitang. This is the only way to do it first!"

Yu Li listened and nodded without saying anything. If she couldn't read, she could only decide on the job first.
Chapter completed!
