Chapter 128 Swiss Scrapers and Hydrostatic Pressure!

The translator, young Liu, froze for a moment, then braced himself and translated it.

"What?!" An old fitter flared up instantly, the veins in his neck bulging: "Foreign expert, you can't just say whatever you want!"

"We measured this flatness with a level; the error absolutely does not exceed 0.02 millimeters!"

"I don't look at data; I only look at the oil film." Klaus did not argue.

He turned to look at Li Jianguo and spat out two words: "Blue oil."

Li Jianguo glanced at Lin Xi and, seeing Lin Xi nod slightly, went to the tool cabinet with a grim face to retrieve a box of aerospace-grade special inspection blue oil.

This stuff was extremely precious and was usually used by the gram.

Klaus dipped a finger into the blue oil and applied a thin layer onto the cast iron lapping tool.

His movements were extremely gentle.

Afterward, he placed the lapping tool onto the granite guide rail and pushed and pulled it gently a few times.

He lifted the lapping tool.

On the black stone, a few blue spots were left scattered here and there.

"This is the evidence."

Klaus pointed at the abysmal contact points, his voice cold: "With this contact rate, as soon as that high-power motor starts, the oil film in the middle of the guide rail will rupture."

"By then, this won't be a machine tool; it will be a rock crusher."

The old fitter's face turned the color of pig liver, but he couldn't say a word.

Facts speak louder than words; the developer won't lie.

"Watch closely."

Klaus picked up the curved scraper, pressed the blade with his left hand, gripped the handle with his right, and pressed the edge against the hard granite.

"Switzerland royal craftsmanship, a closely guarded secret!"

Before he finished speaking, his wrist jerked violently.

"Zzz—" A sound of friction, extremely faint yet exceptionally grating, rang out.

That was the sound of the carbide blade forcing its way into billion-year-old gabbro.

The range of Klaus's movements was extremely small.

Each stroke was no more than a centimeter long, but the frequency was extremely fast.

His waist and abdomen swayed rhythmically with the movement of his arms, as if dancing a wild yet precise waltz on the hard stone.

Stone dust flew.

Every stroke left a tiny, fish-scale-like shallow pit on the black rock.

They were consistent in depth, exactly the same.

This was not just physical labor; it was delicate work that tested one's temperament.

Use a fraction too much force, and the stone would crack; use a fraction too little, and it wouldn't hold oil.

The surrounding workers, who had been unconvinced at the start, gradually shifted to holding their breath in concentration.

Experts look at the technique.

This terrifying ability to control the blade, this muscle memory etched into his bones... Without thirty years of hard work, he couldn't possibly pull this off.

The comments in the livestream exploded instantly:

【This fish-scale pattern is called 'contact points.' Being able to scrape more than 12 points makes one a master, but this foreigner has scraped at least 20 points! God-tier operation!】

【Fun fact: The highest-precision machine tools in the world all have guide rails scraped by hand! Salute to the craftsmen!】

【Carving flowers under a microscope, embroidering on stone—his hand is so steady it looks like he pressed the pause button!】

Ten minutes later.

Klaus let out a long breath and stopped, covered in sweat.

After just ten minutes of high-intensity work, his hands were trembling slightly.

"Blue oil."

He applied it again and lapped it again.

The moment the lapping tool was lifted again, Li Jianguo couldn't help but step forward.

Hiss— A synchronized gasp of air echoed through the Fifth Workshop.

On the originally smooth black guide rail surface, it was now densely covered with tiny blue spots.

They were distributed so evenly, like the brilliant starry sky on a summer night.

Li Jianguo knew without counting.

The density of these contact points definitely exceeded 12 per square inch!

This meant that the gap between the guide rails was physically locked within 0.5 microns!

"I'm convinced."

The old fitter who had wanted to argue earlier took off his hat.

He bowed deeply to Klaus: "This is real skill; I am no match for you."

In the workshops of this era, technique was one's face.

If your skills are inferior, you have to admit it.

Klaus wiped his sweat, the arrogance on his face fading.

He patted the "Stone King" beneath him, his eyes shining terrifyingly bright: "My God, the hardness and stability of this stone are simply perfect!"

"In Switzerland, even if I wanted to scrape, there wouldn't be such good material for me to scrape!"

"As long as I scrape the remaining guide rails, I am confident I can make the crawling error of this machine—zero!"

Applause.

It was unclear who started it, but the sparse applause gradually turned into a thunderous roar.

Lin Xi stood behind the crowd, a smile curling the corners of his lips.

At this moment, Klaus was no longer that "hostage" who had been brought here against his will.

Instead, he was the respected "Teacher Klaus" in the Fifth Workshop.

"Don't rush to applaud."

Klaus raised his hand to press down.

Although he couldn't understand Chinese, he understood the look in everyone's eyes.

He turned back to the table and carefully unfolded the yellowed blueprint.

"Scraping is just the foundation."

"What truly determines whether this machine tool can reach 1-micron precision is this."

The blueprint unfolded.

The complex cross-section looked like a maze, and the dense German annotations made one's eyes dizzy.

But Zhao Qiang only took one look, and his eyes nearly popped out.

"Hydrostatic spindle?!" Zhao Qiang exclaimed involuntarily.

He threw himself directly onto the blueprint, wishing he could press his face against it: "Is this that 'floating spindle' the West has been working on?"

"That's right." Klaus pointed to the cavity at the core of the spindle and explained: "Traditional ball bearings have wear, no matter how high the precision is."

"But this thing is different."

"It uses a high-pressure oil pump to inject a layer of high-pressure oil film between the spindle and the bearing bush."

"The spindle is completely suspended in oil, with zero contact between metals, zero wear!"

"And..." Klaus's eyes flashed with intensity, "The oil film has an averaging effect, which can automatically reduce the spindle's runout error by ten times!"

"Even if there are flaws in the spindle machining, as long as the oil film is stable, the precision can be locked at 1 micron!"

The livestream comments refreshed again:

【Holy crap? Oil film suspension? Isn't this just putting a 'liquid bulletproof vest' on the spindle?】

【Got it! As long as I don't make contact, you can't wear me down! This is the scumbag... oh no, it's the perpetual motion machine principle!】

【The averaging effect is too invincible! Reducing the error by ten times is equivalent to turning on a ten-times-precision beauty filter!】

Silence.

Deathly silence.

Everyone who understood the field was stunned.

This was the pearl on the crown of industry!

It was top-tier technology that the West strictly guarded against China!

Now, this blueprint was right in front of them, within reach.

Zhao Qiang's hands were trembling; he slapped his thigh hard: "As long as we build this, our machine tool can reach 1 micron? Let's do it!"

"But..." Klaus suddenly sighed, pouring a bucket of cold water on them.

"We can't build it."

"Why?" Li Jianguo was anxious, "We have the blueprints; even if we have to gnaw at it, we will gnaw it out!"

"It's not a processing issue; it's the components."
