The Red Era, the Opening University Speech

Chapter 53 Design completed!

After receiving Li Mu's new plan, Huang Xinhua, Liu Ze and Wang Yang continued to work overtime in the laboratory to catch up with the progress.

Liu Ze and Wang Yang, both young men in their twenties, were yawning constantly due to staying up all night, and Huang Xinhua's eyes were even red.

Li Mu wanted to persuade them to take a rest, but it was no use.

Huang Xinhua worked until late at night and finally completed the theoretical design of the diamond grinding wheel.

"Success!" Huang Xinhua checked the derivation several times and after confirming that there was no problem, he couldn't help but wave his fist.

Hearing the noise, Liu Ze and Wang Yang came over at the same time.

"Teacher, is it solved?"

"Great, it's finally solved."

Li Mu didn't feel comfortable leaving early this time, so he stayed until now.

"Li Mu, come here and take a look." Huang Xinhua first nodded to the two students, then called out to Li Mu.

Huang Xinhua waited for Li Mu to come over before continuing, "There is no problem with the theory of diamond grinding wheels. Take a look and see if there is anything missing."

Of course, Li Mu didn't think he could see any problem with Huang Xinhua.

However, after comparing the theory with the data, he had no problem with this.

After checking everything, Li Mu quickly said, "Professor Huang, I can't see any problems. I think we can start trial production."

Huang Xinhua seemed to be slightly relieved, and then said: "Don't worry, although the most difficult problem has been solved, there are still many small problems to deal with."

"For example, the issues you mentioned in your manuscript just now, such as the cutting coolant and spindle coolant, as well as the workpiece fixing method and so on."

Li Mu pondered for a moment and said, "In fact, it is mainly a problem of the coolant. When the diamond wheel rotates at high speed for cutting, electrodes and arcs will be generated."

"And during the dicing process, the crushed particles can also be cleaned to reduce silicon powder contamination on the wafer surface."

"If nothing better is done, I suggest using alcohol and liquid carbon dioxide as coolants."

Alcohol has a good cooling effect, and liquid carbon dioxide is a high-pressure, low-temperature medium that can control the temperature within a very low range. Both are good choices.

However, Huang Xinhua considered other factors: "The cost is too high and it is not suitable for industrial production."

Li Mu was actually aware of this and raised the suggestion in order to confuse the public.

"Well, it's over for today. You guys go back first. I'll discuss it with several professors from other majors to see if we can come up with a feasible plan." Huang Xinhua pondered for a long time, but had no idea for the time being, so he had to give up for the time being.

……

The next day, Li Mu went to class as usual.

However, after class, he would occasionally go to the laboratory to help Liu Ze and Wang Yang solve problems with the design drawings.

Everything is progressing in an orderly manner.

On the third day, cheers were heard in the laboratory.

Huang Xinhua waved his hands excitedly: "It's done, it's done!"

After discussing with several professors at school, he finally solved the coolant problem.

Other problems were also basically resolved during these three days.

Next, it’s trial production.

As long as it succeeds, the country's semiconductor level will take a big step forward.

"Finally succeeded!" Liu Ze and Wang Yang, whose eyes turned red from staying up all night, were also excited.

After so much hard work, it finally paid off!

"Where is Li Mu? Call him over quickly and report this good news to the dean!" After Huang Xinhua was excited, he quickly asked Liu Ze to find Li Mu.

"Teacher, you forgot that Li Mu told us today that he was going home." Liu Ze replied. "Why go back now? Forget it, let's go and inform the dean first."

The three of them hurried to Qian Shuyan's office.

When Qian Shuyan saw Huang Xinhua coming in with a rosy face, he knew there was good news.

"Dean, we have completed the design of the cutting equipment. As long as there are no problems with the trial production of the machine, we can achieve industrial production!" Huang Xinhua said in a low voice as soon as he came in.

This matter is a top secret project.

Qian Shuyan was also a little dumbfounded. He knew it was good news, but he didn't expect it to be such good news.

He thought it would be at most a breakthrough, but he didn't expect that he could already produce it on a trial basis!

"Tell me quickly." Qian Shuyan hurriedly pulled Huang Xinhua to sit down.

Huang Xinhua briefly explained the entire process of developing the ultra-thin diamond wheel cutting machine. After confirming the news, Qian Shuyan could no longer sit still.

"Good news! Good news! Let's go, let's go directly to the First Ministry of Machine Building and tell Leader Qiu the news." Qian Shuyan stood up and walked out.

After getting in the car, the four of them rushed to the First Ministry of Machine Building.

……

One machine department.

Lu Weimin, director of the wafer factory, is discussing with Leader Qiu about seconding Huang Xinhua's research group to join the research base to overcome the problem of cutting equipment.

After listening to Lu Weimin's request, Leader Qiu pondered for a while and said, "I will discuss this matter with the leaders of the Ministry of Culture and Education. You just go back and wait for the news."

Secondment is not difficult, but the system is different, so you have to inform the Ministry of Culture and Education in advance anyway.

Lu Weimin was delighted and was about to leave when the secretary outside the door suddenly walked in: "Leader, Dean Qian and Professor Huang from Beijing Institute of Technology are here with two students."

The secretary whispered in the leader's ear.

"Old Lu, wait a minute, the person you want is here! It's a good opportunity to meet him together." Leader Qiu called Lu Weimin.

Not long afterward, Qian Shuyan and Huang Xinhua brought Liu Ze and Wang Yang into the office.

"Leader Qiu, the design plan for the cutting equipment has been completed!" Qian Shuyan spoke directly as soon as he entered the door.

This time, not only Leader Qiu was surprised, but even Lu Weimin on the side widened his eyes in shock.

He was still considering a secondment, so this worked out?

"Sit down quickly and tell me how you succeeded." Although Leader Qiu was surprised, he did not believe that Qian Shuyan would joke about such a thing, so he quickly asked his secretary to make tea.

Huang Xinhua then took out the drawings of the ultra-thin diamond wheel cutting machine and explained the entire research process again.

Leader Qiu couldn't understand the drawings, but Lu Weimin did.

"Did you, Professor Huang, draw this blueprint?" Lu Weimin couldn't help but exclaim as he looked at the blueprint.

There are inevitably errors between theoretical research and actual production.

He has been immersed in mechanical manufacturing for decades, and he can tell at a glance what drawings can be made and what cannot be made.

This design drawing can be said to be fully in line with the current processing conditions. At least there is no flaw at first glance.

"I don't have that ability." Huang Xinhua smiled and continued, "Most of the design drawings were completed by Li Mu, and during the research process, he also gave me a lot of inspiration, such as the diamond grinding wheel..."

Huang Xinhua talked about Li Mu's merits and contributions.

But as he was talking, Huang Xinhua suddenly felt something was wrong.

Put aside your doubts for now and continue reporting.
