Sure enough, there were only 82 students, and there were 7 professors/lecturers/vice deans in mechanical and electrical engineering, who were on site to observe Chief Engineer Wei's lectures and help the town.

Fortunately, these students who came to the class were all mechanical and electrical technology enthusiasts who were very interested/admired/had a good impression of Lingfeng Technology Company.

After the roll call, Wei Da opened his mouth and said: "Thank you again for your love, my name is Wei Da, you can call me Professor Wei or Chief Engineer Wei, hello students!"

The students replied neatly: "Hello Professor Wei!"

There is not much time, four times a week, two classes each time, the arrangement of about time, what to teach is arbitrary; Wei University is purely an elective course, and many people are not interested in coming.

Of course, Wei Da didn't care, he accepted the order to come to give a lecture, and there were only a few people, and he just came to give a half-day lecture every week, and it was easy to get it done.

What exactly is it about... Read aloud?

No, no, no, that's meaningless, Wei Da feels that he can't fool these people, it must be valuable;

Wei Da explained: "Time is limited, and I am not good at theoretical teaching, so let's talk about my experience and popularize the skills/technologies/trends of industry to you..."

[Operation of Nine-Axis Industrial Machine Tool]

[CAD Software Drawing Skills]

[Accuracy Improvement of CNC Machine Tools]

[5-Axis Machining Center Operation]

[Global Latest Technology Summary]

All of them were very practical techniques, and the students immediately became interested and listened carefully; Wei Da's attitude was also very serious, without perfunctory meaning.

Let's start talking about [machine operation] skills----

"If you want to do a good job, you must first sharpen your tools, machine tools as the main production tools, a wide range of uses, precision is a very important performance! ”

"Ordinary machine tool 0.02mm"

"CNC machine tool 0.005mm or more"

"Five-axis machining center around 0.001mm"

"Nine-axis industrial machine tool approx. 0.00005mm"

"The island nation technology reaches 30 nanometers!"

"The five-axis 0.001mm is already the highest-end equipment that Chinese private enterprises can buy!

Wei Da's tone was disdainful, and he kept shaking his head, if it weren't for the super machining center, he could only polish by hand, and he had the world's top fitter technology, which was more awesome than a machine tool.

"For example, the machine tool in front of you has an accuracy of only a ridiculous 0.05 mm, hehe, I can surpass it even by hand, believe it or not?"

Students: "......" is so good!

The students were speechless, but the professors were a little moved, knowing that this was not the case.

It's really possible to be a top fitter!

But Chief Engineer Wei... Will it be a top fitter?

"It doesn't matter if you don't believe it, wait a minute, let's talk about the problem of machine tools, the accuracy of machine tools, depends on their own extreme accuracy, maintenance, operation technology. ”

"The lack of maintenance on the lathes here has led to a 15 percent reduction in ultimate accuracy, as evidenced by the fact that we cut two steel columns and drilled and turned the internal and external threads. ”

If you don't agree with each other, you will start work, turn the steel column, the students of the two classes are grouped, and they are full of interest and start drilling and turning the steel column, which is very simple.

Requirements: Outer diameter 8cm/inner diameter 7cm

Thread: Tight triangular thread / size arbitrary

The 10CM diameter steel column is clamped on the machine, the alloy tool rotates at high speed, and the sharp drill bit "呩la" slowly cuts into the steel column, making a very harsh sound.

The frequency of "Zizizi~~~" varies

Wei Da wandered around the groups, pointed out the technology, showed the technical know-how, what process to do first, and then what process to do have requirements, choose where to go under the knife...

The bargain machine tool here is far inferior to the DMG machining center imported from Germany, there are too many problems, and the accuracy has been seriously reduced, barely 0.05mm!

The best is only 0.02mm...

Moreover, students are not good at technology, and they don't know much about the operation of machinery, after all, they are mainly liberal arts, and their main work in the future is design/research/testing/drawing.

However, in Wei Da's view, qualified designers must understand the performance of machine tools, otherwise it will be difficult to become a famous designer, let alone an expert!

Those who don't understand the machine tool are purely laymen, how can the laymen give full play to the technology? Design your uncle? The technology can't meet the design expectations at all, and everything is meaningless.

Soon, the processing is over, and it is basically qualified!

Barely in line with the quality of 0.08mm.

To tell the truth, in terms of operational ability, the technology of these elite college students is not as good as that of secondary school students who graduated from mechanical and electrical technical schools, and they are all supported by theory.

Group 1: 80.06mm/70.02mm

Group 2: 80.04mm/70.05mm

Group 3: 80.03mm/70.07mm

Group 4: 80.06mm/70.08mm

Grades are mainly determined by luck and probability...

Wei Da's tone of calm admonition ---

"I want you to remember that in order to become a professional researcher/designer/mechanical expert, you must be familiar with all kinds of industrial equipment and be able to use it yourself!"

"Don't focus on theory/practice, otherwise when you deal with equipment in the future, you will find... I don't know anything, college is a pure waste of time. ”

Some students are not convinced, in the future, they will do their own design and drawing work, proficient in machine tools, why do they do? Some students feel that they have benefited a lot, who knows what to do in the future?

The current form of employment is not optimistic!

A large number of factories have closed/stopped/reduced production, but the number of graduates is increasing, and there are a large number of engineers, and now they are gradually becoming worthless, but there is a shortage of people on the front line.

The question is... They can't do it in practice...

In the competition between the first-line and technical school students, it is obvious that there is no advantage, unless you do management;

So there's nothing wrong with what Professor Wei said~

Wei Da has just taken a look around, and has found some key training objects with high potential, serious attitude, and ingenuity, and they will be divided together in the future!

"The first time we meet, the first time we go to class, I'll show you a hand!" Wei Da smiled indifferently, and walked into front of the machine tool with the tools in his toolbox.

Crackling, three times five divided by two, the machine tool is dismantled piecemeal, cleaned, repaired, welded, polished and reassembled completely, and processed by yourself.

It is also an 8CM/7CM threaded pipe.

After repair, the accuracy of the machine tool has increased, Wei University also has a BUG against the sky, it is purely open, and the students next to him have long been shocked, this Professor Wei is awesome!

The machine was dismantled in minutes...

It shows that they are very familiar with the equipment, just like a certain part of their body, which is not good for ordinary people; Wu Guozhen and they also went to the front to watch and check Wei Da processing.

There is a feeling... This man is made of machines!

Born with the talent of dry machinery, the temperament is completely integrated into the machine tool, forcing the extraordinary, and soon cut this rebar column and handed it to everyone for testing.

Outer diameter 80.00mm/inner diameter 70.00mm

Accuracy beyond the micrometer detection range!
