Chapter 136 Industrial Machine Tool, Sword Drawn!

"Bang!" He Zhenhua stepped forward abruptly.

The floor mat under his feet let out a dull thud:

"Environmental monitoring complete, temperature difference locked! Foundation settlement... is zero!"

"Reporter, He Zhenhua!"

Next was Liu Xiaodong. He bit his lip tightly and roared in a slightly youthful voice:

"CNC system underlying logic self-check passed! Command response latency... is less than 1 millisecond!"

"Reporter, Liu Xiaodong!"

Jiang Jun used all his strength and shouted loudly:

"Closed-loop feedback system normal! Grating ruler data locked!"

"Reporter, Jiang Jun!"

Finally, there was Zhao Qiang.

This "Zhao Two Thousandths" who was once humiliated for having "clumsy hands."

At this moment, he straightened his back, the veins on his neck bulging, and roared with all his might:

"Mechanical structure assembly complete!"

"Hydrostatic oil film rigidity peak confirmed!"

"Spindle runout... 0.3 microns!"

"Ultra-precision CNC machine tool, full machine commissioning, all complete!!"

"Reporter, Zhao Qiang!"

This shout reverberated through the enclosed workshop, making people's eardrums ache.

It shattered the silence of the Gobi Desert.

It shattered the "backward" label that had weighed on China's industry for decades.

In Lin Xi's mind, the originally noisy cross-temporal live broadcast room froze eerily for a full three seconds at this moment.

Immediately after, the barrage exploded like an avalanche, directly obscuring his entire field of vision!

【I'm broken, brothers... This is our industrial machine tool!】

【Looking at that military green, I'm crying like an idiot.】

【That's quancheng green! That's our own stone!】

【If we had this thing back then, we...】

【This is 1981! In that era where we were blockaded to the point of needing to import even screws, they made it!】

【Salute! Everyone stand up!】

The screen full of "Salute" and red national flag emojis obscured Lin Xi's vision.

That resonance across time and space flowed through his entire body like an electric current.

Lin Xi closed his eyes, forcibly suppressing the stormy waves surging in his chest.

He did not order to start the machine.

Instead, he turned and strode toward the red secure telephone in the corner.

That was the direct line to the General Command Headquarters of the base.

Lin Xi picked up the receiver. His fingers were slightly white from excessive force.

"I am Lin Xi."

His voice was surprisingly calm, "Please connect me to General Commander Zhang."

The short three-second wait felt as long as a century.

A slightly weary but dignified voice came from the other end of the phone.

"I am Zhang Zhengguo."

Lin Xi looked up, his gaze passing through the anti-static glass. Once again, he looked at the black behemoth standing quietly.

"Please tell Elder Qian, tell the country."

"We have sharpened the 'sword'."

The other end of the phone fell into a deathly silence. It lasted for ten seconds. There was only the static of the current.

Subsequently, Zhang Zhengguo's voice, usually dignified and steady, now carried a hint of uncontrollable trembling:

"Lin Xi... are you sure?!" "This is not just a machine tool!"

"Sure!" Lin Xi replied decisively.

"Good! Good!! Good!!!"

"Stay exactly where you are!! No one is allowed in or out!"

"The guard company will immediately seal off the constant-temperature workshop! Not even a fly is allowed to fly out!!"

"Elder Qian and I... will be there immediately!"

...

Constant-temperature workshop. Elder Qian, Zhang Zhengguo, and several base experts walked in wearing silver-gray anti-static suits.

There were no flowers, no applause, not even a word of unnecessary pleasantries.

This was an exam. In the center of the exam room was that precision CNC machine tool.

Lin Xi stepped forward, his body standing straight: "Report!"

"High-precision CNC machine tool is now complete!"

"Positioning accuracy: 1 micron, repeated positioning accuracy: 0.3 microns."

"Spindle speed: maximum 3000 rpm, spindle runout 0.3 microns."

"Machining accuracy: 1 micron, 300 mm lead error: 2.8 microns!"

"It has reached the 'Industrial Machine Tool' standard." "Please instruct!"

Elder Qian's gaze lingered on the machine tool for a long time. It was the look of a parent watching their own child, filled with both expectation and stern scrutiny. After all, whether this child could succeed had a bearing on the fate of the country.

"Lin Xi." Zhang Zhengguo broke the silence. He turned around. He took a heavy bar stock from the metal box behind him and handed it to Li Jianguo.

"Straight to the final exam." "C0 grade... ball screw."

As soon as these words were spoken, the experts who understood the industry gasped.

This was not a normal test piece. This was to directly machine the core component of the "machine that makes machines"!

In the industrial field, for every level the precision grade is raised, the difficulty increases exponentially.

C0 grade means that within a total length of 300 millimeters, the lead error cannot exceed 3 microns. This is also the area where the West has had the tightest stranglehold on us. This is hell-level difficulty.

Lin Xi calmly adjusted his anti-static gloves and nodded at Li Jianguo. "Master, load the material."

Li Jianguo took a deep breath, his chest heaving. At this moment, he was no longer that grumpy old man who loved to have a couple of drinks of strong liquor. He was a top-tier Eighth-Grade Worker. He was also the "hands" of this machine.

His hands, wearing white gloves, steadily took the bearing steel bar stock, clamped it, and calibrated it. Every movement seemed to have been practiced thousands of times, without a trace of unnecessary trembling.

"Close the safety door." "Start the hydrostatic pump." Following Lin Xi's command, a very faint "rustling" sound, which one would almost have to prick up their ears to hear, arose. That was the sound of high-pressure oil being injected into the spindle gap.

There was no shrill sound of metal friction. The heavy spindle, supported by the oil film, began to rotate silently. The rotational speed climbed to 1500 rpm.

Some experts subconsciously took half a step back, seemingly waiting for that familiar roar of a machine tool. But, there was none. The entire workshop was exceptionally quiet. The eight-ton gabbro base greedily swallowed all the vibrations. If they hadn't seen the chuck spinning at high speed, people would have even thought the machine was stationary.

"Start rough machining." The command was entered. The cutting tool slowly cut in. Hiss—!

A wisp of gray-white iron filings slid gracefully along the tip of the tool. They did not turn blue or black due to overheating, but maintained the original cold, bright luster of the metal. Perfect cold cutting.

Elder Qian's hands, which were originally behind his back, had been placed in front of him at some unknown point, tightly clasped together. Rough machining ended, which was just a matter of a few minutes. But the real test was only just beginning.

"Enter precision turning program." Lin Xi's voice remained steady, "Target accuracy, micron level."
