Courtyard House: A Major Power's Heavy Industry, Hand-Crafted Nuclear Fusion

"Load the workpiece."

At Su Zheng's command, Zhao Ming, who had been waiting on the sidelines, acted swiftly.

He carefully installed a finely ground bearing sleeve onto the chuck, his movements skillful and steady.

At this moment, the third workshop was completely silent.

Hundreds of eyes were fixed on the grinding machine that was spinning "silently".

Although the "coin pillar" test just now proved the machine's stability, it was just spinning without load.

Only under cutting load can the true quality of a machine tool be tested.

"Invite the knife."

Su Zheng stood beside the control panel, not personally handling the tasks, but issuing orders like a commander.

Zhao Ming took a deep breath and turned the feed handwheel.

The grinding wheel slowly approaches the workpiece.

"Sizzle—"

As the first spark flew out, an extremely delicate cutting sound, like a silkworm spinning silk, echoed in the workshop.

The experienced craftsmen immediately perked up their ears.

This sound...something's not right!

Previously, when this machine was working, it made a "sizzling" sound, with a rough, metallic tearing sound.

But the sound now is a continuous, gentle, and even melodious "buzzing" sound.

This means that the contact between the grinding wheel and the workpiece is extremely uniform, and the cutting process is extremely stable!

"Depth of cut 0.05, feed rate 200," Su Zheng ordered again.

"yes!"

As the cutting process continues, long, silvery-white shavings fly out from the blade, tracing graceful arcs in the air before falling into the waste bin.

"Look at those shavings!"

In the crowd, a veteran level-7 craftsman couldn't help but exclaim, "Uninterrupted! All long scrolls! This means the main shaft isn't vibrating at all! It's incredibly stable!"

One cut and it's over.

Zhao Ming withdrew his sword and stopped the machine.

Before the machine had come to a complete stop, Chief Engineer Li rushed forward impatiently, holding a surface roughness sample and a micrometer in his hand.

He lightly ran his fingernail across the surface of the workpiece, and his face instantly showed an expression as if he had seen a ghost.

"This...this was ground out?"

Chief Engineer Li stared incredulously at the gleaming surface. "This smoothness is at least Ra0.04! That's mirror-finish grinding! The highest precision listed in the original manual is only Ra0.08!"

"What? It's two levels higher than the original factory version?"

Factory Director Yang was so excited that his hands were shaking.

He didn't understand what Ra was, but he knew what "higher than the original" meant.

This means it's not just fixed, it's upgraded!

"Wait, it's not over yet."

Su Zheng remained calm, as if all of this was expected.

He glanced at the oil pressure gauge, then at the coin that was still standing steadily on the spindle box.

"Increase the RPM to 3000."

"what?"

Zhao Ming was taken aback. "Master, the factory maximum RPM is only 2500! Won't 3000...?"

"Tick it up." Su Zheng only uttered one word.

"yes!"

Zhao Ming gritted his teeth and turned the speed control knob.

The motor emitted a slight whistling sound, and the tachometer needle soared, instantly breaking through the redline and settling at 3000.

Everyone in the audience was on tenterhooks.

Liu Haizhong gripped the railing tightly, cursing inwardly: Explode! Explode already!

However, the machine remained as stable as a mountain.

The coin remained completely still.

"Double the feed rate to 0.1 mm. Double the feed rate to 400."

Su Zheng's voice rang out again, carrying a kind of calm that could drive anyone mad.

"this……"

Zhao Ming's hands were trembling.

These parameters were something I never dared to even imagine before!

This is playing with fire!

But under his master's piercing gaze, he did as he was told.

"Sizzle—!"

The cutting sound grew louder, and sparks gushed out like a waterfall, instantly illuminating Zhao Ming's face.

rough!

Wild!

But it's still... terrifyingly stable!

The second cut was completed in only half the usual time.

Chief Engineer Li took measurements again.

"Ra 0.05! Roundness error... still can't be measured!"

Chief Engineer Li's voice cracked with excitement, "Not only has efficiency doubled, but accuracy hasn't decreased at all! This...this is simply a miracle!"

"Double the efficiency?"

Factory Director Yang astutely grasped this word.

"right!"

Chief Engineer Li quickly calculated with a slide rule, "With the current cutting parameters, we can process 120 pieces per hour, compared to only 80 before! Efficiency has increased by... 50%! No, considering the scrap rate is zero, the overall efficiency has increased by at least 60%!"

60%!

This number was like a bombshell, exploding in the crowd.

In this era where "production is combat," what does a 60% increase in efficiency mean?

This means production capacity will double!

This means that the military production task can be completed ahead of schedule!

This means that Hongxing Steel Rolling Mill will become the benchmark for the entire system!

"Good! Good! Good!"

Factory Director Yang said "good" three times in a row, his eyes welling up with tears.

He grabbed Deputy Factory Director Li and patted him hard on the back. "Old Li! Did you hear that? 60%! This time, we not only avoided a disaster, we're going to make a huge contribution!"

Deputy Factory Director Li was also stunned by this sudden happiness, and couldn't stop smiling:

"Yes! Yes! It's all thanks to Su Zheng! It's all thanks to your decisive action in going to invite him!"

"continue."

Su Zheng did not stop despite the cheers around him.

"3500 RPM. I need to test its limits."

crazy!

Everyone thought Su Zheng was crazy.

3500 RPM, that's already 40% overclocked!

But at this moment, no one dared to object.

Because in this workshop, Su Zheng is like a god.

……

Half an hour later.

When the final extreme test ended, the heavily modified M1320 grinding machine delivered a result that left everyone breathless:

Maximum speed is 3800 rpm (factory speed is 2500 rpm).

Machining accuracy Ra0.02 (original factory Ra0.08).

Overall processing efficiency improved by 35% (conservative estimate).

Spindle temperature rise is less than 5 degrees Celsius (factory standard 20 degrees Celsius).

This is a data set that completely crushes and overwhelms the competition.

Su Zheng took off his gloves and threw them on the control panel.

He turned around, looked at the data record sheet posted on the blackboard, and finally a satisfied smile appeared on his lips.

"This is a real industrial machine."

He said it calmly.

"Whoosh—!"

The next second, the workers, who had been unable to contain themselves any longer, surged forward like a tide.

"Long live Master Su!"

"The technical consultant is awesome!"

It's unclear who started it, but several strong young men lifted Su Zheng up and tossed him high into the air.

"oh--!"

Cheers, whistles, and applause merged into a huge wave of sound that almost lifted the roof off the workshop.

Factory Director Yang and Deputy Factory Director Li stood aside, watching Su Zheng being tossed into the air, their faces full of satisfaction.

They knew that the Red Star Steel Rolling Mill had struck gold.

In this moment of revelry, no one noticed that Yi Zhonghai and Liu Haizhong, hiding in the corner, were slinking away along the wall.

Yi Zhonghai's back was hunched over, as if he had aged ten years in an instant.

He listened to the cheers behind him, each word seeming to mock his incompetence and shortsightedness.

He knew that his era had truly come to an end.

……

at the same time.

The main gate of the factory area.

A black Hongqi sedan with a special license plate was driving in silently.

Just as the gatekeeper was about to stop them, he saw the car window roll down, revealing a dignified face that was often seen in newspapers, as well as a special pass from a ministry stamped with a bright red seal.

"Quick! Open the door! Salute!"

The gatekeeper was so startled that his hat tilted to one side, and he quickly stood at attention and saluted.

The car slowly drove in, but instead of going to the office building, it headed straight for the noisy third workshop.

Inside the car, the dignified old man listened to the cheers in the distance, a curious smile appearing on his face.

"Looks like we're a step too late. The show's already begun?"

The secretary, sitting in the passenger seat, turned around and whispered, "Minister, according to the information we just received, the 'Su Zheng' we're looking for has just... drastically modified that broken German grinding machine."

"Oh? A major modification?"

A glint flashed in the old man's eyes. "Interesting. Let's go see what kind of person this 'Little Zhuge Liang' is, the one that our Factory Director Yang went to invite so late at night."

The black sedan, like a silent shark, slid into the boiling ocean.
