Han Sanjiang and his family followed Saburo Sasaki to visit the industrial area of Wakadai for a week, and they saw some semi-automatic machine tools, which can bend a predetermined steel plate into the desired shape, and then go through various processes to become some kind of mechanical accessories, as well as advanced injection molding equipment, which can be injection molded into a car shell at one time.

I also saw the thread rolling machine, put a semi-finished product into the thread rolling machine, only a blink of an eye, rub out a screw, as well as screw production equipment, pour the screw embryo into the funnel, the funnel keeps rolling out the screws, one by one the self-tapping screws continue to jump out of the machine, and after a while, a large number of self-tapping nails appear in front of you, which makes people look shocked and drop their jaws.

In addition, there are CNC lathes for the production of locks, and the lock cylinders produced are made of copper, and some small holes and bolt eyes in the lock holes are produced by CNC. See the end, is a safety punch, but also with numerical control, the wool of the punch is sent to the punch die of the punch through the conveyor belt, one by one punched out of the product, automatically jump into the blank bag, and then moved by the person, so that the efficiency of the punch far exceeds the manual, the manual to feed the wool one by one to the mold, and so on, and then use the clamp to clip the product out, which in time and process, has been a big difference. It looks like the simplest punch is so advanced that it is eye-opening.

As soon as the time of the visit was over, Sasaki smiled and said, "Secretary Han, our technical exchange time is over! Tomorrow I will take you to the Tokyo Imperial Garden and Tokyo Tower to have fun! When it is over, I will take you to sit and slowly walk around the streets and alleys of Tokyo, and then go to other cities after playing Tokyo!"

Han Sanjiang replied with a smile: "Mr. Sasaki, we understand your kindness, we came this time for technical exchanges, but we didn't communicate anything, and we saw your advanced technology! I was thinking, Mr. Sasaki, can you sell us some CNC lathes, and we can also learn your advanced technology?"

Sasaki Saburo looked at Han Sanjiang, and then replied seriously word by word: "Secretary Han, we just asked you to come and visit, and we didn't mention to you about selling CNC lathes! Our Japanese technology is rarely passed out, I think you'd better not mention these requests, we are friends, fortunately there are no outsiders here, if it spreads, our cooperation will be interrupted by the Japanese government! Therefore, in the future, you had better avoid this topic in Japan!"

Jiang Yuanqiao said with a smile: "Mr. Sasaki, we just want to buy some numerical control, and we didn't bargain with you, so we won't be so sensitive, right? Why is it involved in politics again, isn't this commercialization?

"Hehe, Mayor Jiang, you are wrong again, we in Japan have always been very conservative in terms of technology, and no country can say it, you know it in your heart! I don't need to say more! I'll buy you a plane ticket to go back to China tomorrow! lest I leak my mouth, and I can't even be the chairman of my business association!" Saburo Sasaki replied with a helpless sigh.

Fang Xinyue deliberately said: "Mr. Sasaki, didn't you say that you would take us out to play? Why do you regret it now? We haven't seen the Royal Garden and Tokyo Tower yet? Also, what about the streets and alleys of Tokyo? We haven't eaten the best sushi in Japan? You just drive us away, Saburo Sasaki, you're too unauthentic, aren't you?"

Saburo Sasaki flicked the big sleeves of his kimono, snorted, and replied: "Who is to blame for this? Isn't it that you Secretary Han is insatiable? I asked you to come to visit, it is a good intention, not so much technical exchanges, but we in Japan like to communicate with people with advanced technology like ourselves, and we will never allow people and units worse than us to buy our advanced equipment. Not even a single screw will do! This is the current situation in Japan, you can do it yourself, don't say any more, buy a plane ticket tomorrow and go back, no, it's better to leave today! Lest there be any trouble, I made a big mistake by calling you here, and I can't continue to make mistakes!"

"Han Sanjiang, are you insane? This is good, what kind of lathe did you buy? I hurt the old lady to come for nothing! I was really angry with you!" Fang Xinyue glared at Han Sanjiang and scolded.

Saburo Sasaki didn't pay attention to what the three of them said, and called his driver to buy three tickets back to Xiaoshan International Airport. After giving the order, he said: "Secretary Han, I'm sorry, you must leave Japan tonight, the sooner the better! I have already asked Shimizu-kun to buy a plane ticket! Wait a while, I'll send you away!"

Han Sanjiang smiled helplessly and said, "Okay, I don't embarrass you, then you take us back to pack our luggage, and we will leave Japan immediately." "Originally, everyone was happy and happy, but as soon as Han Sanjiang mentioned buying a CNC lathe, this hateful Sasaki Saburo suddenly turned his face, which was faster than turning a book, which was really embarrassing!

Saburo Sasaki didn't feel embarrassed at all, but looked triumphant, and drove them back to the hotel to get their suitcases.

As soon as he packed up, Saburo Sasaki urged: "Everyone hurry up, the plane will take off in two hours, bring your passports and valuables, and let's rush to the airport immediately." ”

The three of them didn't bring much stuff with them, they packed it up in just a few minutes, and then got off the elevator and followed Saburo Sasaki into his car, Sasaki Saburo drove the car, speeding all the way, it was twelve o'clock in the evening, many shops were closed, there were no pedestrians on the road, the billboards on the roof, neon flashing, and the street lights on both sides of the highway were always on.

After more than an hour, Saburo Sasaki finally sent Han Sanjiang and them to the airport, took three tickets from Shimizu-kun's hand, and sent them to Han Sanjiang, his attitude changed greatly, and he said with a smile: "Secretary Han, don't blame me, we are very sensitive to these aspects in Japan, and my predecessor was accidentally fired, I hope you can forgive me!"

Han Sanjiang had no choice but to accompany the smiling face and replied: "Understand, long live understanding! Mr. Sasaki, you are good! Goodbye!" said and took the ticket handed over by Sasaki Saburo and waved away.

"Wait!" Before Han Sanjiang could enter the waiting room, Saburo Sasaki shouted loudly.

Han Sanjiang turned around and smiled, Saburo Sasaki caught up, hugged Han Sanjiang for a while, patted him on the shoulder and said, "I'm sorry, brother! I have wronged you!" let go of Han Sanjiang, watched the three of them leave, waving his hands as he walked, wiping tears inseparably.

Fang Xinyue saw Saburo Sasaki crying, so she whispered, "That guy Sasaki doesn't know what's going on?

The careful Jiang Yuanqiao also found out, sighed and said, "This Japanese is too sensitive, isn't it tiring to live like this?"

Han Sanjiang smiled weirdly and replied: "This guy is a psychopath, nervous, if he doesn't sell it, he won't sell it? Why do you want to drive people away? Isn't it just a few CNC machines, is it so sensitive?"

Jiang Yuanqiao said: "The Japanese have been conservative for a long time, and their country does not accept foreign students, and this sudden exchange with us can be regarded as the greatest openness! We can't completely blame Saburo Sasaki, he also did this out of helplessness!"

At about four o'clock in the morning, Han Sanjiang and the others flew from Tokyo to Xiaoshan International Airport, and it was five o'clock when they got off the plane, the sky was bright and drizzling.

Out of the airport, Han Sanjiang asked Fang Xinyue: "Yueyue, do you understand those computer languages?"

Fang Xinyue smiled heartily and replied: "In three years, your store will use a CNC lathe that is more advanced than their Japan! I promise you!" She said this very surely, otherwise she would not have said it.

Han Sanjiang replied with a smile: "It's really worth the trip! Hurry! Hurry! I have a question I want to ask you, why can the small sharp knife on the CNC with the same conical shape turn the thread, and the thread saturation is better than the thread made on my reducer? What is the principle?"

Fang Xinyue explained with a smile: "Secretary Han, first of all, I want to tell you, that is not a turning tool, it is a thread knife, the shape of the knife is made according to the equal distance between the thread gums, the thread turning tool is turned in three times, and the turning is successful after the distance from the tooth root!" This turning has thread programming, with the thread code writing method, all the products that have been turned by CNC turning, the precision is between the error value of 30 molecules and 1 millimeter, that is, the distance of 1 millimeter is divided into 30 parts, and its error value will not exceed one thirtieth of a millimeter, so it is the most ideal processing tool. The study of numerical control is to improve the quality of products, and what cannot be made manually can be produced through numerical control! This numerical control is not only used in hardware, but also electronic circuits, lattice circuits, and super-large integrated chips can be widely used, and this field will become the world's top technology in the future. ”
