The next morning, Zhao Zhenzhong and the other two came to Antai Machinery Company, about 10 kilometers away from the manor. Although Antai Machinery Company has been established for more than a year and a half, the factory buildings in the huge factory area in front of me, and the roar of machinery from time to time, the entire company should have a certain degree of strength.

"The entire factory was also built in about a year and a half?" Zhao Zhenzhong was a little surprised at the construction speed of Antai Machinery Company.

"How can it be that fast?" Zhou Hao explained with a smile, "This place was bought by my sister when she founded Huamei Investment Company in 26. Since then, the site has been leveled, water, electricity and other infrastructure has been built, and the entire factory has been built at the end of 27. Antai Company has just entered here after its establishment in 28 years."

"So that's it." Zhao Zhenzhong was relieved and asked again: "Listen to the sound of the machines over there, can the machinery company produce them now?"

"It's not that fast. It should be Li Yunshan leading a group of people to do the experiment." Then, Zhou Hao introduced to Zhao Zhenzhong: "In addition to the machining factory, Antai Machinery Company also has several institutions such as Vehicle Power Research Center, Metallurgical Materials Laboratory, and Chemical Materials Laboratory. It can also be said that although the sparrow is small, it has all the internal organs. Although the equipment introduced by various institutions is not at the top level in the United States today, it is also first-class."

Looking at the factory in front of you and listening to the roar of machines coming from time to time, Zhao Zhenzhong sighed: "Look at this huge factory and listen to the institutions you mentioned, you will know that you have been working hard in the United States in the past few years. This is much better than the best result I expected before I arrived in the United States."

"Haha, then Lao Zhao, you must thank my sister very well. Without the gold mountains she has found, it would be impossible for these achievements in front of her to achieve."

"I can't achieve these achievements alone, and every overseas student has put in a lot of effort." After correcting it, Zhou Tian continued to propose: "Let's go over and see what Li Yunshan and the others are busy with now."

"That's right. Just let Lao Zhao guide them." Zhou Hao nodded in agreement.

"Let's take a look at the mechanical processing equipment of this era first. Before I understand the situation clearly, I should not command it blindly. After all, there are many differences between what I have mastered in the past and this era." Zhao Zhenzhong said with a self-awareness.

In a factory in the Power Research Center, Zhao Zhenzhong and the other two saw Li Yunshan who was covered in oil and was directing everyone to debug an engine. Seeing Zhao Zhenzhong and the other two, Li Yunshan hurriedly said to everyone: "Everyone have a rest first and sort out the relevant records of this experiment so that we can improve next time."

"Did you make this engine yourself?" Zhao Zhenzhong stepped forward and looked carefully, and asked Li Yunshan.

"We tried it ourselves." Li Yunshan explained, "Our company has just been established for more than a year and a half. It is basically composed of our overseas students. It is difficult for us to develop new products by ourselves for a while. Uncle Zhou asked us to follow up on the mature products of some large companies in the United States, first copy and then innovate."

Zhao Zhenzhong nodded and said, "This idea is correct. What companies are you following up and studying now?"

"It is mainly products from several different auto brands of General Motors. From the first V-type water-cooled eight-cylinder engine developed by Cadillac in 1914 to the six-cylinder truck engine that Chevrolet has just launched this year, we have all collected it. What is being experimented with is to imitate the six-cylinder truck engine that Chevrolet has recently launched this year."

"How is the progress? When will the copy be successful?"

"What is currently conducting experiments is the first experimental product we have tried to produce after surveying and mapping the Chevrolet engine. Judging from the current experimental results, in addition to some places that need to be readjusted and improved processing accuracy, the expected goals have basically been achieved. It is estimated that by next summer, we will be able to produce small batches." Li Yunshan said proudly.

"It's not bad, but we can't just copy it. In addition to patent issues, this is also because copying is not conducive to our own research and development and innovation. We can completely create better products of our own based on reference to American products. For example, the engine of this truck is six-cylinder. Can we transform the six-cylinder engine of this Chevrolet into eight-cylinder? or even ten-cylinder or twelve-cylinder?" Zhao Zhenzhong reminded.

Li Yunshan's eyes lit up and he thought, "Although I haven't tried this, it should be okay to add two cylinders based on the six-cylinder engine layout based on the layout of other brands. However, if you increase the number of cylinders, it will probably be difficult. Even if you do it, the overall volume and weight of the engine will increase greatly and cannot be installed on existing trucks."

"Haha, the existing truck cannot be installed, so let's develop a truck that can accommodate this new engine. But the premise is that this new engine is strong enough and durable." Zhao Zhenzhong smiled.

"Apart from the engine being tested, are there any other achievements in your Vehicle Power Research Center?"

"Other things we have mastered are the four-wheel brake technology launched by Buick in 1923, but this technology was used in cars at that time, and after improvement, we can use it on trucks. In addition, it was successfully copied. Last year, Cadillac launched a synchronous transmission, which has also conducted some research on tracked tractors, etc.."

"The company has only been established for more than a year and a half, and it is already very good that you can master these things." Zhao Zhenzhong nodded with satisfaction and said, "However, don't ignore the new achievements that have emerged in the development of safety glass and other automobiles. Okay, you can arrange this first, and then take us a few of us in the machinery company."

Under the leadership of Li Yunshan, Zhao Zhenzhong and the other two came to the machining factory again. After seeing the lathes, milling machines, planers, grinders, punches and other mechanical equipment of this era, Zhao Zhenzhong breathed a sigh of relief. Although these equipment in front of him were very different in performance from the CNC machine tools in later generations, their basic functions were still the same.

Looking at the equipment in front of you and the busy employees who are processing some experimental components, Zhao Zhenzhong asked: "Li Yunshan, how much do you know about the combination machine tools?"

Li Yunshan thought for a while and replied: "When I was studying in college, a teacher said it and learned some from books and from school laboratories. However, I think that although that thing can increase product output a lot after the product is finalized, it is not applicable to our current machinery companies."

Zhao Zhenzhong nodded and said, "As for our current machinery companies, everything is still in the experimental stage, and combined machine tools are indeed somewhat inapplicable. However, in the future, we will very much need the automated production technology developed from combined machine tools in China. I will give you 8 years. Can you lead overseas students to fully master the design, manufacturing and improvement capabilities of the machine tool industry? Can you master the automated production technology developed from combined machine tools?"

After thinking for a while, Li Yunshan said: "If it is a general-purpose machine tool such as turning, milling, planing, grinding, and punching, we have now mastered the relevant design, manufacturing and improvement capabilities. This can be seen by improving existing equipment and processing various experimental components. But if we have various professional machine tools, I think it will take about two years to learn and improve. For combined machine tools and the automated production technology developed from this, I think it will take longer, but it should not take eight years. Of course, this is estimated to be when all aspects are fully met."

"As for the conditions you need, as long as it can be solved through funds, it will not become a problem." Zhou Tian promised on the side.

"Haha, with the words of my master, I promise to complete the task assigned by my master in advance." Li Yunshan also promised with a smile.

"In addition to engines and vehicles, as well as the machine tool industry, you also need to organize personnel to master hydraulic transmission technology and seamless steel pipe production and processing technology. These are technologies that we need very much in the future in China." Zhao Zhenzhong reminded, "These technologies are related to vehicle production, but not only to vehicle production. For example, in addition to being closely related to vehicle brake control and stamping processing, hydraulic transmission technology is also closely related to engineering machinery. You can study bulldozers that use hydraulic transmission control, and control bulldozers with hydraulic transmission to bulldozers bulldozing, dumping, and backing shovels. Of course, hydraulic transmission control technology and seamless steel pipe technology can also be applied to the production of cranes, excavators and other engineering machinery and military production fields."

"In addition, I would like to remind you that when using various mechanical equipment for processing and production, you must follow the equipment operating specifications and produce safely. For example, if the punch press does not strictly follow the equipment operating specifications, it is easy to hurt your hands and cause accidents of broken fingers or palms."

When Li Yunshan heard what Zhao Zhenzhong said, he said, "Uncle Master, please speak slowly, I'll find paper and note it."

Zhao Zhenzhong waved his hand and said, "No need to remember. I will sort out a complete written request for you after I go back."

Then, Zhao Zhenzhong and the other two came to the metallurgical laboratory under the leadership of Li Yunshan. Here, Zhao Zhenzhong asked Jiang Fengxue, Tian Wentao and Zhu Hanwen, who were responsible for metallurgical materials research, and said: "If you are in charge of a steel plant now, what kind of steel can you produce?"

"Overall construction and daily common steel should be able to be produced. But other special steels are still not produced." Jiang Fengxue, the leader, said with some embarrassment: "We have also asked Yunshan to buy several artillery barrels through some methods, and have carefully studied the metal components in them, and even made one by one by the same metal ratio. However, the barrel we made ourselves, even if the ingredients are the same as those made by Americans, has a big gap in toughness and strength."

"Oh? You have been able to analyze the metal components in it through the finished product? This is very good!" Zhao Zhenzhong asked excitedly, "How did you do it?"

"We conducted the analysis through metallographic experiments," Jiang Fengxue explained. "In 1863, the British Sobi transplanted petrophysics methods, including sample cutting, sample grinding and polishing, polishing and shaving, to steel research, and developed metallographic technology. Now, with the improvement of optical metallographic microscopy technology, it has been widely promoted for microscopic analysis of metallographic and alloys, and is a basic technology in metallographic materials."

"So that's the case." Zhao Zhenzhong understood and analyzed: "The components are consistent and the performance difference is too large. That can only be said that our processing process is wrong. It should be because there are shortcomings in the heat treatment process."

"That's right." Jiang Fengxue and the other two nodded in agreement.

"Since you have the ability to analyze the composition of special steel, try more processing techniques based on these composition ratios, and compare them to see which method is more conducive to improving the performance of the product." Zhao Zhenzhong suggested, "In addition, when studying special steel, you must also study related technologies at the same time. For example, the welding technology of special steel. Many times, some metal components that have undergone special processes cannot be welded using daily welding rods, but special welding rods need to be used. The most obvious of this is the high yield steel used for submarine shells and warship armor. Welding cannot be achieved using normal welding rods. This is also a problem that you need to solve in your metal material research. As for the experimental conditions, tell Yunshan and let him coordinate and solve them. Metal materials are crucial to our future development and must not be ignored."

After listening to Zhao Zhenzhong's words, Jiang Fengxue and Li Yunshan hurriedly agreed.

Tian Wentao, who was standing beside him, asked in surprise: "Sir, how do you know so much? We have been studying in the United States for 4 years and were quite confident, but Mr. He has not learned these things in China, so how can he know the professional knowledge of metal materials?"

"Haha, I know more about mechanical processing. After all, I founded the bicycle factory in Nanyao. As for the knowledge about metal materials I know, it is just some of the fur I learned during the mechanical production process. If I ask me to do metallographic analysis, I know nothing." Zhao Zhenzhong explained with a smile.
