Urban Black Technology Boss

No matter which field of the manufacturing industry is inseparable from high-precision machine tools, it can be as large as the key parts of national defense weapons, aerospace, and aircraft carrier ships, as small as watch gears, and various precision instruments.

Unfortunately, due to the relatively backward domestic technology and the blockade of the latest technology by European and American countries, the domestic high-precision machine tool production technology has not been able to keep up.

To give the most common example, the precision required for the refill of a ballpoint pen is very high, and its gap must be guaranteed to be within 5-7 microns, that is, an error of 3 microns.

Although the production technology is very simple, if the production equipment does not meet the requirements, there will be ink or no ink.

The tip of a small ballpoint pen was not localized until 2017.

Shangjingcheng Aerospace Research Base is a national key unit with the most advanced machine tool equipment in China.

Last year, in order to process the engine parts on Shenzhou NO.12, the Bureau of Science and Technology bought a second-hand ultra-precision five-axis machine tool from a German company at a high price.

Although it is only a second-hand product, the maximum processing accuracy can reach 0.005 microns (5 nanometers), which can be regarded as a high-precision machine tool that has entered the nanometer level.

Such equipment can be used to process the engine parts of Shenzhou No. 12 without any problems. How could it fail to meet the requirements of the so-called new NA engine parts.

Hearing Tang Long's words, Chief Engineer Yang of the scientific research base immediately straightened his neck and argued: "How is this possible! We use an ultra-precision five-axis machine tool imported from Germany's Hammer Company. The machining accuracy can reach 0.005 microns. There is no problem with making Shenzhou No.12 engine, how could it not meet the standard?!"

"The maximum accuracy requirement for the core components of the NA engine on the design drawings is 0.1 nanometers, and the parts you process are still fifty times worse than the design standard!" Tang Long sneered and replied unceremoniously.

"..." Several engineers in the scientific research base were suddenly speechless.

According to the design drawings they obtained, the maximum accuracy requirement of the core components is indeed 0.0001 microns (0.1 nanometers).

It's just that the most advanced ultra-high-precision machine tools in the world today can only achieve a machining accuracy of 0.001 microns, and it is impossible to reach the level of 0.1 nanometers.

Since the NA engine is a high-precision equipment, the scientific research base will naturally not take the risk of dismantling the prototype to measure the size of the core components.

So they can only regard the data on the design drawings as a clerical error, thinking that the correct number should be 0.001 microns.

Even so, there is no way to make parts accurate to 0.001 micron in China, so we can only settle for the next best thing and process them according to the standard of 0.005 micron.

But they never expected that the core components of the NA engine were really required to be 0.1 nanometers, and now they are blind.

However, they couldn't figure out why Tang Long could tell at a glance that the core components of the counterfeit engine were not accurate enough. Could it be that he had clairvoyance?
"Mr. Tang, we really can't meet the standard you mentioned. Do you think there is any way to solve it?" Chief Engineer Yang asked in a soliciting tone.

Since Longteng International can produce a prototype, it means that they must have a way to solve this problem, it just depends on whether they are willing to come up with such a high-precision machine tool.

Seeing that the other party was subdued, Tang Long didn't bother with him too much. Firstly, he didn't have so much free time, and secondly, he seemed immodest.

But the current problem still depends on him to solve it, and hope that others will have nothing to do.

"I'll solve this problem. Find me a quiet place. I want to make a phone call." Tang Long turned to look at Academician Wu Wei.

"No problem, this way please." An administrative staff next to him immediately greeted warmly.

Following the staff of the scientific research base to an unoccupied office, Tang Long closed the office door and looked up.

After checking with [Data Glasses] and confirming that there is no electronic monitoring equipment around, and no one else within 50 meters, Tang Long muttered silently in his mind and disappeared instantly.

Entering the world of "Mechanical Enemy", he didn't stop for a moment, letting the robot workers directly pack an ultra-high-precision machine tool in the robot factory into a box.

After shrinking the container into the dimensional space, Tang Long returned to the real world.

Then he teleported to Longteng International Xiangjiang factory, took out the container and restored it, and ordered two robot engineers to stand by on the spot.

After teleporting back to the Shanghai Aerospace Research Base, Tang Long took out his mobile phone, pretended to make two calls, and returned to the factory building.

"I have already called the headquarters, and the headquarters agreed to borrow the machine tool from the laboratory. I have arranged for someone to send it to the Xiangjiang factory." Tang Long said directly to Academician Wu Wei and others.

Hearing that Tang Long agreed to lend the machine tool, Academician Wu Wei's eyes lit up immediately, and he asked enthusiastically, "Mr. Tang, do you need our help to arrange the delivery?"

Such an ultra-high-precision machine tool with an accuracy of 0.1 nanometers has never been heard of on the market. No matter which country it is placed in, it will be treasured as a national treasure.

Longteng International has the right to lend it out. Could it be that they manufactured this machine tool?

Academician Wu Wei was overjoyed at the thought of being able to see such an advanced machine tool.

As long as he can borrow it for a few more days, he has the confidence to use such a machine tool as a master machine to process sub-machine tools with an accuracy of 0.001 micron.

After all, Huaguo's copycat ability is not something to brag about!

"Okay, you arrange the transport plane to Longteng International's factory, and I'll ask the person in charge to escort it here." Tang Long thought for a while, nodded and replied.

If he followed the normal process by land, it would take at least a dozen hours to travel from Xiangjiang to Shangjing, and he didn't have the patience to wait.

With Tang Long's consent, Academician Wu Wei immediately contacted the relevant departments and directly dispatched a military transport plane from the Xiangjiang Garrison Base to Longteng International Factory to perform the transportation task.

With so many people in the factory, naturally they wouldn't spend waiting here.

Tang Long brought an LT4 industrial robot this time, and it happened that Colonel Zhu Guanglong was there, so he simply showed it off.

After opening the one-meter-high special suitcase, a huddled humanoid robot appeared in front of everyone.

"[Alpha I] activated!"

Following Tang Long's order, a silver-white robot exuding metallic light slowly stood up.

Unlike the LT3 bionic robot, the LT4 industrial robot is made of titanium alloy and has no skin or hair outside the body.

It has a humanized face and a silver-white alloy body, limbs and heads, and black metal joints can be seen on the neck, shoulders and thighs.

At this time, [Alpha I] blue eyes were looking straight at everyone in the laboratory, arms were drooping, and the body was standing at attention.

"This...isn't this the NS5 robot in "Mechanical Enemy"?" A young engineer who had watched the movie "Mechanical Enemy" couldn't help but exclaim.

"Maybe the designer appreciates this shape more, so the shape looks similar." Tang Long explained with a smile.

"Simple anti-human design, is it easy to move?" Seeing that the robot's lower limbs are legs, the young engineer asked subconsciously.

Everyone present couldn't help but frown, all aware of this problem.

The reason why most industrial robots adopt the crawler wheel design is to adapt to the complex ground environment, maintain the balance of movement, and facilitate the movement of loads.

Can such a human-like design really adapt to the complex environment on the moon?
