Wang Zhen's words Zhang Tianming believed, because the other party graduated from a well-known foreign university, and worked in the field of foreign machining for 15 years, five years ago was hired by the board of directors to return to China with a high salary, and his technology can be ranked in Jiangcheng.

Everyone in the factory was very convinced and polite to Wang Zhen, and Zhang Tianming also respected Wang Zhen, so he usually called Mr. Wang.

But no matter how difficult Wang Zhen said, seeing that he couldn't eat the fat in his mouth, Zhang Tianming was still unwilling.

"Having said that, didn't the other party say that they would send technical guidance?"

"That one is called Lin Feng?" Wang Zhen's eyes showed a touch of disdain, "In the machining technology industry, I have never heard of this character." ”

"He's the boss of designing parts."

The disdain in Wang Zhen's eyes became even stronger, "Since he is playing with design, and he doesn't engage in machining, what processing technology does he know." Not to mention him, even those top experts in the industry can't solve the current problems of our factory. ”

"Unless the board of directors agrees to purchase laser CNC machines and superalloy pressure machines."

Hearing this answer, Zhang Tianming gasped.

Laser data machine tools and superalloy pressure machine tools, that are more than 500 million big guys.

For the sake of a 50 million order, go and buy two machine tools with more than 500 million, unless the board of directors has a collective convulsion.

After a long time, Zhang Tianming smiled awkwardly.

"Anyway, let's give it a try!"

At this time, the doorman called.

"Factory director, there is a Miss Zhao Feifei who brought a young man named Lin Feng to find you."

Said Cao Cao, Cao Cao arrived.

"Okay, I'll come down right away."

Hanging up the phone, Zhang Tianming glanced at Wang Zhen opposite.

"Why don't we go meet this person together?"

"Good!" Wang Zhen snorted, raised his head and left.

He also wanted to see what this Lin Feng was capable of.

......

"Miss Zhao, hello!"

"Hello, Director Zhang, this is my boss, Lin Feng."

"Hello Boss Lin!"

"You're welcome!"

After a brief introduction by both sides, Wang Zhen was even more disdainful of Lin Feng, because the machining industry relies on age to eat.

As I get older, I experience more incurable diseases in machinery, and my technology becomes more comprehensive.

And Lin Feng looks too young.

But Zhang Tianming is very enthusiastic.

"Two of you have come from afar, let's go to the office for a hot cup of tea first."

Lin Feng shook his head.

"You don't need to drink tea, Director Zhang, we are here this time to visit the plant of your factory, and by the way to solve some technical problems in our order."

"Okay, I'll take you there."

The four of them entered the gate of the factory a few minutes later, and when they looked around, they saw that the machines inside were all half-used and half-stopped. And the mood of the workers is not high, giving people a sense of twilight.

No way, there are too few orders, and it's good to have half of the machine tools started.

After all, he is the technical director and is most familiar with the machine tools in the factory.

Several people walked to a large machine tool that had started, and Wang Zhen introduced it with a proud face, and his tone was a little show-off.

"This is a S_125 alloy forging machine tool, our factory spent 300 million yuan to purchase five years ago, and it is also the largest and best machine tool in our factory, it uses ....."

At this time, Lin Feng interrupted the other party.

"Mr. Wang doesn't need to be introduced, this machine tool can't make the parts we require."

Hearing this, everyone else was stunned.

Wang Zhen sneered, "Boss Lin, are you too arbitrary?" This machine is mainly used for machining curved parts, and is the most suitable machine for forging the U-shaped parts you need. ”

"Arbitrary?" Lin Feng shook his head.

"S_125 alloy forging machine tool was developed fifteen years ago by David. Krell creative invention, manufactured by Zeus Machinery Production Company, specially used as a machine tool for the processing of curved parts, it adopts high-temperature quenching technology in three calciners, and the forging mouth is made of 9.86 hardness alloy customized model, using rapid air pressure technology, which can produce parts with a total area of no more than 0.43 square meters and a bending degree of no more than 10 mm per meter. ”

Zhang Tianming next to him was dumbfounded, he was only the factory director, and he knew a little bit about technical information, but he was not as comprehensive as Lin Feng.

And Wang Zhen's heart was slightly shocked, and he also knew what Lin Feng said, but he didn't expect that this young man was not in the machining industry, but he understood it so clearly.

But Zhao Feifei thinks it's normal, after all, her boss is a genius.

Lin Feng swallowed his saliva, cleared his throat, and continued:

"The standard error of the parts produced by this machine tool is one tenth of a millimeter, and the minimum error is one fiftieth of a millimeter, and because of the use of rapid air pressure technology, the hardness of the parts created is not enough, and it can be used as ordinary parts processing, but for important parts, especially those that require hardness, the processing effect of this machine tool is not ideal."

When Wang Zhen heard this, he was very surprised, what Lin Feng said just now, he can still find it on the Internet after taking some time, but it is impossible to expose the performance shortcomings of the machine tool on the Internet.

"Is he really an expert in the machining industry, and I was deceived by his age?" Wang Zhen couldn't help but doubt what he had just thought.

But that's not all.

"Moreover, the standard S_125 machine tool has a gear speed of 1034 revolutions per minute, while yours has only 856 revolutions per minute, and this slowing down has resulted in an increase in part error of three thousandths of a millimeter and a reduction in part hardness by 0.12 Rockwell hardness (HRC)."

This time Wang Zhen was really shocked, he knew that the speed of this machine tool had slowed down a little, but it did not have much impact on the processing of parts, so he didn't care.

But now Lin Feng can actually put forward the problem of slowing down the speed with data simply and intuitively.

Even if Wang Zhen tested it himself, he couldn't do it so accurately.

So Wang Zhen couldn't help asking, "How do you know this?" ”
