In this regard, Lin Chen said in the eyes of people's curiosity:

"Speaking of this thing, it is also a problem that has plagued me Daxia for many years, and my Daxia and my former big brother Xiong are also deeply troubled by this thing.

For this thing, the famous "Toshiba Incident" broke out that year, as for what this thing is, this thing is a five-axis machining center. ”

As Lin Chen spoke, a picture was projected on the projection screen behind him, and there was a huge machine half a room in the size of the picture.

At this time, one side of this huge machine is marked with the sign of "Shuguang Five-Axis Machining Center".

Obviously, this huge machine is the one made by the Dawning R&D Center.

"This is a five-axis machining center developed by our Dawning R&D Center and Xia Ke Institute, which has 24 tools that can be automatically switched, and the surface roughness can reach up to 0.01μm, that is, the tolerance can reach the T5 tolerance mirror level!

That is to say, with this machine, the processed parts are directly ultra-precision parts, and there is no need to further continue ultra-precision machining, which greatly saves the process and time!

As for the T4, T3, T2, and T1 tolerance levels above T5, according to known information, all machine tools in the world are currently unable to directly process ultra-precision parts with tolerances of T4 or even T3 or above.

If humans want to process ultra-precision parts that reach the T4 tolerance level or above T3, they can only be processed by grinding processing. ”

Hearing Lin Chen's words, many reporters and guests at the scene nodded lightly as if they didn't understand, but in fact, they didn't know what Lin Chen's T5 tolerance meant.

However, a small number of reporters who knew about parts processing showed shocked expressions, and they looked at Lin Chen as if they were looking at aliens, and their faces were full of disbelief.

Because the more they know, the more they know how amazing the machining tolerance of the Dawning 5-axis machining center is to reach T5.

This tolerance to the T5 level may not seem like much on the surface, and there are T4, T3, T2, and T1 tolerances on top of it.

However, if it can directly process ultra-precision parts with tolerances of T5, it means that it has reached the world-class level!

As for whether there are stronger machine tools in the world, there really is no stronger one in this era.

At present, if you want to process ultra-precision parts with tolerances above T4 all over the world, whether it is Daxia or other countries in the world, you can only achieve such tolerances through grinding!

Therefore, the Dawning five-axis machining center made by the Dawning R&D Center is not simple, and it has a far-reaching impact on a country.

After all, not all parts need to reach the T4 level, and the accuracy of most of the machines on the market is completely enough to reach T5 or T9.

The machining tolerance of the Dawning five-axis machining center can directly reach T5, which is actually far beyond the needs of most parts, and its birth is of great significance!

"It's not scientific, how can you achieve a machining tolerance of T5, which is world-class machining accuracy.

In such a backward country as Daxia, you have developed such a powerful five-axis machining center in less than a year......

This is absolutely unscientific, you must be faking! ”

There was a strong rebuttal at the scene, which was the words of a reporter from the island nation of Tokyo I Daily.

Looking at his appearance at this time, it seemed that he really thought that Lin Chen was faking, and he didn't want to believe that it was true.

Because if this is true, then it is definitely a disaster for the industry of their island nation!

What are the characteristics of their island country's industry that are most famous, and the most famous is not the same precision machining ability as Deyizhi?

And now the Dawning R&D Center has made a five-axis machining center with a processing tolerance of T5 level, if it is true, it will be a disaster for the precision parts industry in the island country!

"It can't be fake, it can't be fake, let time test what our processing tolerance is."

In the face of the incredulous reporter of the island country of Tokyo i Daily, Lin Chen's words were also quite cruel.

Seeing this, the reporter of the island country instantly lowered his head as if his spine had been removed.

Because through Lin Chen's words, he already knew that the Shuguang R&D Center might have really made such a super five-axis machining center.

After all, if Lin Chen used other words to refute him, then he might still not believe it, but when Lin Chen said the words "test it with time", he knew that it must be true.

It's catastrophic news that their island industry is really about to have a big shock, and they can no longer maintain their lead.

On the other side, Lin Chen didn't pay attention to the reporter of the Tokyo I Daily of the island country who seemed to have been pulled off his backbone, and saw Lin Chen continue to say under people's gaze:

"Speaking of which, we were able to develop and produce semiconductor chip production equipment at the 90nm process level in less than a year.

This really relies on the Dawning five-axis machining center with a processing tolerance of T5 and the nanotechnology of the surface of metal materials.

After all, there is no way for us to purchase many high-precision parts, and it is even difficult to find others to process them.

In this case, if we don't have our own 5-axis machining center, we end up with a machine tool that we don't have the production capacity to do......

Here, I would like to express my deep gratitude to several academicians such as Guo Ling and Lu Ke, as well as other professors and R&D personnel!

Without their hard work and overtime to build the Dawning five-axis machining center, the time for our 90-nanometer chips to really land may have to be postponed for a long, long time. ”

After speaking, Lin Chen also bowed deeply.

Of course, while he bowed, he was actually glad that he was fortunate to have a virtual laboratory and a multi-purpose machine that came with the king of copycat system, otherwise it would be really difficult to build a five-axis machining center at dawn.

After all, there is no processing capacity for ultra-high-precision parts, you just have qualified materials and designed drawings, but there is no production and processing capacity, just like there are chickens and eggs.

As for why the weak multi-purpose machine can solve the production problem of the Dawning five-axis machining center, the reason is that the multi-purpose machine has been upgraded.

In August last year, when the total number of users of Shuguang Technology, Rice Mobile Phone, and Shuguang Software Games reached 100 million, this multimeter was also upgraded to a higher level.

Not to mention that the mass of the multi-purpose machine has been increased from 50 kg to 500 kg, the direct processing accuracy has been directly increased from 2 μm to 0.01 μm, rather than the surface roughness has reached 0.01um level.

Although both are 0.01μm, the meaning and difficulty of the representation are different, because in this way can the Shuguang five-axis machining center be produced!

Of course, Lin Chen did not disclose the multipurpose machine to the outside world, and only claimed that he had processed more precise parts through special grinding methods.

As for if they continue to ask what the special grinding method is, a company secret can make them speechless and make them honestly shut up, after all, since it is a company secret, how can they tell you.

Therefore, this time I was able to build a five-axis machining center, and the upgraded multi-purpose machine and virtual laboratory really accounted for more than half of the credit. (End of chapter)
