When the three of them finally understood this, they all showed shock.

No wonder Uncle Sam found it incredible, it turned out that the requirements for precision were too high. For CNC machine tools, such machining accuracy is naturally not a problem, but Niu Xiaoqiang just now is a pure manual operation, if the test results are accurate, it is indeed incredible.

Sam continued to check the instrument, and after a while, he didn't notice any problems. Faced with such a result, he froze for a moment, and then changed to another testing instrument.

As a result, the second testing instrument still gave the same result: the machining accuracy did meet the requirements of 20 microns, and there was no error.

Sam was completely dumbfounded, and he looked at the blank of the part that had only been machined with one arc with a shocked expression, and didn't say a word for a long time.

Niu Xiaoqiang knew what was going on at a glance, and he walked over with a smile: "Mr. Sam, you must have gotten accurate test results, right?

Sam nodded mechanically, then asked in disbelief, "Tell me, how the hell did you do that?"

Niu Xiaoqiang smiled naturally: "Practice makes perfect, you should have heard of the phrase, right?"

Sam nodded and then shook his head, "Of course I know practice makes perfect, but ...... But no matter how skilled you are, there should be a limit, right? What is the concept of 20 microns? Can this really be done by hand?"

Niu Xiaoqiang nodded firmly: "In China, there are many people who can rely on manual processing to achieve this kind of accuracy, and I am not a special case." ”

Sam still couldn't believe it: "But this is 20 microns, not 2 millimeters, manual processing can achieve such accuracy, this, this ......"

Sam said this and asked as if he remembered something: "You didn't use a professional instrument to test after the processing was completed, but just touched your fingers a few times to make sure that the accuracy met the requirements, isn't this too exaggerated?" Could it be that the Chinese really have magical spells?"

Niu Xiaoqiang saw that his performance completely calmed Sam, and he was naturally in a very good mood, and he patiently explained: " Mr. Sam, don't underestimate human perception, the smallest scale that human fingers can perceive is 13 nanometers, if you look at human fingers as big as the earth, then fingers can perceive the difference between houses and cars by touch, of course, ordinary people can't do this, it takes years of training, I learned the relevant skills with my master when I was a few years old, and over time I honed this kind of ability that seems unbelievable to you, which is not surprising at all. ”

Niu Xiaoqiang's explanation through scientific methods finally made Sam accept reality. He couldn't help but praise: "The Chinese are really amazing, if I hadn't seen it with my own eyes, I would never have believed that there was such a thing in the world." ”

Faced with Sam's admiration, Niu Xiaoqiang couldn't be happy. He sighed, showing helplessness: "This is all forced out, our country is implemented by Western countries to implement a technical blockade, domestic enterprises can not buy high precision machine tools, so can only make up for the defects of equipment through manual technology, if you can buy high-precision machine tools, who is willing to spend so much time and energy to learn manual technology?"

Sam nodded slightly: "That's right, people are forced out, boy, you have conquered me in terms of processing, I don't know how much you know in terms of automobile manufacturing?"

Niu Xiaoqiang said with a smile: "I learned the relevant technology of automobile engines from my master, and later I started a business in China, and through hard work, I owned a small car factory that belonged to me, and I personally designed its first heavy-duty truck." ”

Niu Xiaoqiang was just stating a fact, and he didn't brag about how powerful he was. Even so, Sam didn't dare to underestimate him. The reason is simple: if someone can design a completely new truck, doesn't that prove his technical prowess?

Sam asked curiously, "What kind of heavy truck?"

Niu Xiaoqiang smiled bitterly and shook his head: "This type of truck is only exported to Africa, and has not yet entered the American market, and your Excellency will not see it for the time being, of course, if you are willing, you can go to China with me after the New Year, and I can take you to visit my automobile factory in China." ”

Sam has thoroughly recognized Niu Xiaoqiang's status as the company's largest shareholder, and he smiled: "You are the boss, if you arrange for me to go on a business trip to China, of course I will be happy to go." ”

When he said this, he stretched out his right hand and said very sincerely: " My previous attitude was not very friendly, I hope Mr. Niu doesn't mind, in fact, I am not a very difficult person to get along with, the reason why I treated you like that just now, mainly because I want to have a deeper understanding of your personal situation, to be honest, I hate those laymen to blindly command, because this is how Packard Motor Company was destroyed, you are different, you are a very knowledgeable person, I am happy to accept your leadership, I hope we can work together to make Packard Automobile Company reborn. ”

These words are heartfelt, and they are completely in line with Niu Xiaoqiang's prediction of Sam's character. Seeing that Sam fully accepted himself, Niu Xiaoqiang no longer had any worries. He shook Sam's right hand and said with high spirits: "Thank you Mr. Sam for your recognition and support for me, I am not a superficial person, and in the days to come, I will use practical actions to prove that Your Excellency's support for me is absolutely correct." ”

Sam smiled and beckoned to the four researchers not far away, "Everyone hurry up and get to know the new boss." ”

The four of them all walked up to them with a face full of surprise, although they muttered a little to the young Niu Xiaoqiang, but when they saw that Sam was convinced, they naturally wouldn't be bored with themselves, and questioned Niu Xiaoqiang in person.

After the two sides exchanged pleasantries, Sam took Niu Xiaoqiang into the data room. The size of the reference room is not large, only about 10 square meters. Sam came in and took out the key to open the filing cabinet, "This is where Packard's greatest wealth is at present, there are a total of thirteen patented technologies, all of which were developed under my leadership, and I invite the boss to look at them." ”

On the upper level of the filing cabinet are numbered file bags, a total of thirteen, and below are stacked the research and development materials of these patented technologies.

Niu Xiaoqiang picked up the file bag very seriously and checked them one by one, and the others did not disturb him when they saw this, standing aside and waiting quietly.
