Siheyuan: Qin Huairu refused to recognize me in order to enter the Jia family

Slowly remove the remaining screws.

Turned on the machine.

Qin Weidong took a closer look and found that it was just as he had expected.

Remove the tapered screw.

The people around quickly gathered around.

Everyone present had a certain understanding of mechanics, and a closer look revealed visible wear marks on the edges of the screw threads.

"A hero emerges from youth. He can actually find the problem so accurately!" The mechanical expert couldn't help but admire.

Everyone else nodded, except Yi Zhonghai.

Seeing Qin Weidong's skilled techniques, he felt a deep sense of crisis.

Qin Weidong took out a piece of paper and drew a picture on it.

"Can our factory make this picture?"

Qin Weidong looked around and saw that everyone looked embarrassed.

At this time, Yi Zhonghai volunteered and said, "I'll do it!"

Qin Weidong curled his lips and said, "Are you okay?"

Yi Zhonghai snatched the blueprint and said coldly, "Just wait."

After saying that, he turned around and started grinding the mold on the low-speed machine tool.

More than an hour later, Yi Zhonghai came to Qin Weidong with a polished tapered screw and said proudly, "How is it? Who said I can't do it?"

Qin Weidong looked at the parts in Yi Zhonghai's hand and couldn't help shaking his head.

It is impossible to manufacture a tapered screw in such a short time. Yi Zhonghai must have taken some shortcuts.

"Did you measure the size?" Qin Weidong asked back.

Yi Zhonghai was stunned when he heard this. He had indeed forgotten about this during the manufacturing process and had just made a casual gesture with his hand.

Based on my many years of experience, the error should not be too big.

"There's definitely no problem with the size. Are you nitpicking?" Yi Zhonghai asked, somewhat unconvinced.

Qin Weidong did not explain much after hearing this. He turned around, took out the measuring device and handed it to Director Li.

"Director Li, please measure it yourself, or someone will accuse me of cheating!"

Director Li took the measuring device, and soon his face turned cold and he threw the screw made by Yi Zhonghai to the ground.

"Yi Zhonghai! You are a veteran in our factory, but the error is more than one centimeter. How dare you show off?" Director Li said angrily.

Yi Zhonghai couldn't believe his ears and said tremblingly: "How...how is it possible?"

"It's such a waste of everyone's time, Xiao Qin, you should come instead!" Director Li turned and looked at Qin Weidong.

"Okay! Then I'll do it myself." Qin Weidong nodded.

Although he had received a technical reward, Qin Weidong was still a little nervous as it was his first time to do it.

After all, this is a real technical job!

If you are not careful, you will fail miserably, just like Yi Zhonghai, who was completely useless.

Processing tapered screws requires great patience and time, and an afternoon passed in a flash.

Qin Weidong worked non-stop for more than three hours. If he hadn't received the reward from the Bajiquan master and strengthened his body, he wouldn't have been able to persist so easily.

Amid everyone's increasingly shocked gaze, the tapered screw was completed.

Everyone around was stunned, especially Director Li, who looked at Qin Weidong as if he had seen a treasure, with greed in his eyes.

The leaders of other factories were rolling their eyes around, as if they were planning something.

Only the mechanical experts who have been working nearby know how difficult the whole process is.

The lathe was adjusted to the lowest speed, and the blade in Qin Weidong's hand did not shake for three hours, and the processed size was exactly the same.

Mechanical experts all suspected that he had been practicing with the sword since he was in the womb. How could anyone be so steady?

It's simply a humanoid machine!

However, he was also grateful in his heart that being able to observe and learn would be of great help in improving his skills.

"Okay, take it and harden it with quenching."

Qin Weidong could finally take a break.

The mechanical expert took the initiative to help, carefully took the piece of cloth and wrapped it, then trotted towards the heat treatment workshop.

Qin Weidong, who was standing next to him, sat down on the machine tool, not caring about his image at all.

No one else thought there was anything wrong with Qin Weidong's behavior.

Anyone would be tired after three hours of intensive work.

If you’re not tired, you’re not a human being!

Soon, the mechanical expert came back with the repaired part and replaced the original worn part.

Qin Weidong stood up and restored the machine using the previous method.

Before long, the machine was exactly the same as before.

The next step is the test drive phase.

No matter how well you have done before, everything still depends on the results. Without results, it is all empty talk!

"Director Li, come here!" Qin Weidong said.

Director Li nodded and then came to the machine.

"I opened it!" Director Li looked at everyone, his voice trembling slightly.

Actually, it’s not his fault.

This is not an ordinary machine tool. If it can be repaired, it will be a milestone breakthrough.

Boom!

With a low roar, the machine started.

The big guys seemed to be surrounding them.

"Deliver the materials! Why are you still standing there?" Director Li urged.

Everyone also reacted.

“Feeding”

"Connecting materials"

"Measurement accuracy"

……

The mechanical expert took the material and began measuring.

Everyone looked tense and didn't dare to breathe, for fear of affecting the measurement results.

In order to prepare the data, the mechanical expert measured several more sets of data to find the average value.

Seeing the final result, the mechanical expert couldn't help but said excitedly:

"The error is within a reasonable range, only 0.5 mm. We succeeded!"

popping.

clap clap...

Everyone's eyes were filled with tears, and they finally got rid of the anger. From now on, they no longer have to worry about the foreigners' faces when repairing gantry milling machines.

If we can take this small step today, there will definitely be a big step forward in the future!

Director Li and others showed a sense of pride.

People from the department had come before, but they were all helpless.

Now it has been fixed by our own people.

This is definitely a landmark event!

The steel mill broadcast a piece of news that shocked the entire factory:

"Comrade Qin Weidong of our factory was awarded the first-class merit of our factory for overcoming technical difficulties. He also serves as the director of the technical department and enjoys special allowances. Let us congratulate Comrade Qin Weidong together!"

wow...

This is a large factory with more than 10,000 employees.

Only a small number of people knew what had happened before, but now the announcement has been broadcasted throughout the factory.

Everyone in the factory knew it at the same time.

Qin Weidong had no idea what was going on in the factory at this time, because he had left work early with the tacit consent of Director Li.

When he arrived at the parking lot, Qin Weidong suddenly discovered that his car was locked!

"Could it be that someone made a mistake?" Qin Weidong thought to himself.

At this moment, a voice coming from a distance broke Qin Weidong's thoughts.

"Is this car yours?"
