CNC machine tool

  The individual business license issue can only be put aside for now. Lan Wufeng said that he could still secretly sell these small commodities in the market using the original method, as long as he carried a little less goods with him each time. If they really encountered industrial and commercial law enforcement, it would not be a big deal to hand over an electronic watch wrapped in a canvas bag, and the loss would be within an acceptable range.

  After Lan Wufeng left, Lin Zhenhua wrapped the money that Lan Wufeng had brought in newspaper and stuffed it into a box under the bed. With such a large sum of money, he couldn't take it to the bank for deposit, because those few savings clerks at the bank were very gossipy. If he took several thousand yuan to deposit, it's estimated that half of Fenghua County would know about it by the next day.

  To his sister Xiaofang, Lin Zhenhua did not reveal the situation of making money. He was afraid that Xiaofang would leak the news to her best friend, and secondly, he was worried that if Xiaofang knew about the large sum of money at home, she might not be able to sleep well at night. He took out a few hundred yuan from the pile of money and handed it over to Xiaofang, telling her that this was the household expenses. Xiaofang didn't have any special feelings about this, as she had just extorted more than ten different electronic watches from Lan Wufeng and was thinking about which watch to give to which good friend, and there was no room in her mind to think about money matters.

  "Brother, I took so many electronic watches from Lan Wufeng, you won't blame me, will you?" Lin Fanghua asked nervously.

  "It's okay, take it if you want."

  "I wanted to give it to my classmates. In the past, when you were away serving in the army and not at home, they all took good care of me, and I never had anything to repay them." Lin Fanghua explained.

  Lin Zhenhua ruffled his sister's hair with his hand and said with a smile: "You just gave it away, I didn't blame you. These watches add up to only a few dozen yuan, as long as you're happy."

  "Brother, isn't our family very rich now?"

  "From the perspective of personal family life, it is indeed quite wealthy."

  "What other angle is there?" Lin Fanghua asked.

  "A person lives a lifetime, can't just think about eating and sleeping, must have some career. If you want to do business, this money is far from enough." Lin Zhenhua said.

  "Brother, what kind of career do you want to pursue?"

  "It's still hard to say," said Lin Zhenhua, actually he himself hadn't thought too much about it, just vaguely feeling that as a traverser, he should have some achievements, but as for what these achievements were, he hadn't thought clearly.

  The next day, Lin Zhenhua still walked into the workshop with the sound of the bell. As soon as he entered the workshop, he was startled to see that a glass house had been set up in one corner of the workshop, and a small piece of carpet had been laid at the door. Through the glass wall, Lin Zhenhua could see that it was the MK800 donated by Spiesheer Company inside.

  "Kobayashi, how's this? Do you think it's suitable for us to arrange the CNC machine tools like this?" Lu Xiansheng walked up to Lin Zhenhua and asked with a pleased expression.

  "Director Lu, where did this glass house come from?"

  "Of course, we built it." Kong Qingsheng said in a matter-of-fact tone, "When we were on the train, Old Fan taught us about it. He said that CNC machine tools are just machines with a computer installed inside, and the computer controls the operation of the machine..."

  "That's right." Lin Zhenhua said.

  "Exactly!" said Lü Qingsheng, "I saw it at the provincial computer center. Their computer room is like this, with a glass house and a carpet inside. So when we got back, we started working on this thing. With Director Zhu sitting here in charge, it was done in two days."

  Lin Zhenhua scratched his head: "Uh, actually, let's not be so nervous. The CNC machine is just a circuit board, and it's no different from the ordinary electrical appliances in our home. As long as the machine is grounded properly and avoids static electricity, it's fine."

  "Never mind, anyway the glass house has already been built, now it's just waiting for you to start." said Lu Xiansheng.

  "Has it been decided who will operate the CNC machine now?" asked Lin Zhenhua.

  "It's settled then, Peng Gang, the leader of the milling class, will operate it, and Yang Xin will be his apprentice." Luo Qingsheng said, "Right, Xiao Lin, I heard that Yang Xin was recommended by you."

  Lin Zhenhua hastily explained: "Director Luo, I just said that Yang Xin is relatively young and may accept new things faster. I didn't mean to say that I must have Yang Xin do it."

  "Never mind, Xiaolin. I'm familiar with your little tricks," Lu Xiansheng said disdainfully. "Go to the container workshop and ask around. Who doesn't know that Old Yang plans to recruit you as his son-in-law?"

  "Ah...I'm dizzy..." Lin Zhenhua said tearfully.

  The MK800 was just pulled back from the train station yesterday, and under the command of Fan Shibin, several workers carefully removed its packaging and placed it in a small glass house. Luo Chen gave orders that no one except Lin Zhenhua, Peng Gang, and Yang Xin were allowed to touch this sacred machine.

  Although touching is not allowed, looking is still permitted. Throughout the day, workers in the metalworking shop took turns peeking at this machine from outside the small glass house, all of them marveling at it. This was a device that was completely different from all the machines in the workshop, with a layer of spray-painted casing covering the entire exterior, on which were written foreign characters that no one could recognize. On the left side of the machine, there was a small display screen, below which were dozens of buttons, none of which anyone knew what they were for, but just looking at them made you feel mysterious and high-end.

  "Xiaolin, what do we need to prepare?" asked Peng Gang, the head of the machining class, as he walked over to Lin Zhenhua. Behind him followed Yang Xin, who was trying to suppress her excitement but couldn't help looking a bit timid. Lin Zhenhua clearly saw that on Yang Xin's right wrist, she was wearing an electronic watch with a red strap, which was obviously given to her by Lin Fanghua overnight. Just then, Yang Xin looked up at Lin Zhenhua and found him staring at her wrist, so she quickly hid her hand behind her back and gave Lin Zhenhua a mischievous smile.

  Lin Zhenhua saw the girl's radiant smile and suddenly felt refreshed. He said with a smile, "No need to prepare anything, we can start work now."

  Peng Gang took out the key, opened the door of the glass house, and then made a gesture to Lin Zhenhua, indicating that he should go in first. Peng Gang was the best milling worker at Hanhua Machinery Factory, 30 years older than Lin Zhenhua, but at this moment, he had a kind of respectful feeling towards Lin Zhenhua like an apprentice seeing his master. He knew that the 19-year-old young man in front of him was the only one in the factory who could operate this mysterious machine bed, and with his own intelligence, he had convinced the Americans to give this machine bed to Hanhua Factory.

  Lin Zhenhua didn't show excessive modesty and was the first to walk into the small house. Luo Qingsheng, Peng Gang, Yang Xin and others followed in a line, standing on both sides of the CNC machine, waiting for Lin Zhenhua's demonstration. Outside the glass house, a group of workers gathered around, all waiting to see how the CNC machine worked.

  Lin Zhenhua smiled slightly at Luo Chen and others, saying: "Everyone doesn't have to be nervous. In fact, the operation of CNC machine tools is much simpler than traditional machine tools. It controls many operations with programs. We only need to set a specific program, and those complex operations such as tool alignment and feed can be automatically completed by the machine. Let's take a look, I'll demonstrate how to mill a keyway first."

  As he spoke, he clamped a workpiece onto the chuck and began pressing keys to select operating instructions. He pressed one key after another while explaining, with Peng Gang and Yang Xin leaning forward, listening intently and taking notes on their notebooks, their faces radiating excitement.

  Lin Zhenhua set the relevant parameters, pressed the start button, and the machine whirred to life. The milling cutter spun rapidly, the workpiece moved back and forth smoothly, and the iron shavings cut out automatically fell into the scrap slot. The entire processing process was as smooth as a flowing cloud.

  "Too good!" Peng Gang exclaimed, "This is even more delicate than a human hand."

  "That's for sure, it's computer-controlled, much stronger than human hands." Lu Xiansheng chuckled and said to Peng Gang.

  Lin Zhenhua shook his head and said, "Actually, it's not like that. At least so far, computers can't replace humans. In mechanical processing, even the best CNC machine tools can't match the precision of an excellent craftsman."

  "This is indeed the case," said Lao Gan, "Take our workshop's Zhou Houcheng Master, for example. When he processes a plane surface, as long as he touches it with his hand, he knows which part is flat and which part is not, more accurate than using calipers to measure it. This skill, I think computers can't learn."

  "Come on, Master Peng, you try too." Lin Zhenhua gave up his position to Peng Gang.

  Peng Gang walked forward and stood in front of the MK800. The old machinist, with 30 years of work experience, had sweat all over his palms and a mixture of excitement and nervousness on his face.

  "Master Peng, let me explain it to you. Look here, this is the control panel. First, you need to..." Lin Zhenhua began explaining the various settings on the panel one by one to Peng Gang. The buttons were all labeled with English words, which Peng Gang couldn't recognize many of, but as soon as Lin Zhenhua explained the setting methods to him, he understood immediately.

  The CNC milling machine is still a milling machine, and the operations that need to be done are still those operations, it's just that the human operation process has been turned into a computer program. Lin Zhenhua was speaking while Peng Gang was trying it out himself, after several twists and turns, a qualified keyway was finally machined.

  "Ah, I'm so tired." Peng Gang wiped the sweat from his forehead, a happy expression on his face, and said, "I didn't feel this tired even when I was milling 20 keyways on the universal milling machine."

  "You just pressed a few buttons and you're already tired?" Rong Qisheng asked with a smile.

  "This thing is really too good, as long as you learn how to press these buttons, even the most difficult workpieces can be processed." Peng Gang said with emotion.

  "Alright, Master Peng and Yang Xin, from today onwards, the two of you will follow Xiao Lin as apprentices. You must quickly grasp the use of CNC machines. In the future, when our country becomes rich, our workshop will replace all machines with CNC ones. At that time, the two of you will take over Xiao Lin's role and become everyone's masters."

  Peng Gang smiled and said: "I have no hope, I am 49 years old, in another 10 years I will retire. Yang Xin still has a chance, at that time, this world will be yours and Xiao Lin's."

  "Master Peng, what nonsense are you talking about?" Yang Xin rebuked, turning her head to glare at Lin Zhenhua, as if complaining that he had affected her reputation.
