When he came to the industrial park, Saburo Sasaki asked the driver to stop the car, and then said to Han Sanjiang: "Secretary Han, we have arrived, this is the distribution center of our copper product processing factory, our factory was also very loose in the past, and then I felt that this is not only unsightly, but also affects the environment, so all the factories gathered together to form today's scale! Let's get off the car and take a look! Please get off the bus!" Saburo Sasaki speaks Chinese very well, and it seems that he is a Chinese expert.

Everyone got out of the car with Saburo Sasaki, the driver drove the car away, Han Sanjiang followed Saburo Sasaki into a factory that made air conditioning accessories, he said with a smile: "This is our largest air conditioning processing factory in Japan, you see that it is all digital, all CNC machining, basically no manual production!" He pointed to the rows of CNC inside and said with a smile.

Han Sanjiang, Jiang Yuanqiao, and Fang Xinyue looked at the processing workshop at the same time, the rows of lathes inside were neatly placed, even the aisles were in straight lines, neatly arranged, the workers inside were wearing uniform work clothes, the ground was clean and spotless, and there was not a drop of oil stains on the lathe, which was polished beautifully, and the workers' clothes were also very neat, all wearing workers' hats, and the female workers' hair was all ponytails, the braids were not long, and they stretched out from the Dharma protector holes behind the hats. The aisle is about three feet wide, the main road is about five meters long, and the floor is painted with green paint, which looks beautiful as new. There is a lamp on the steel frame in the tall factory building every other zhang, the whole workshop is bright and spacious, and the windows around are very large transparent glass windows, and the sunlight shines into the workshop, which has a warm feeling. There are also occasional large transparent tiles on the roof, reflecting the light.

When the workers saw Saburo Sasaki coming, they took the initiative to bow down and greet him with Japanese etiquette, and Saburo Sasaki also returned the salute with Japanese etiquette.

Han Sanjiang didn't know what to do, so he asked with a smile: "Mr. Sasaki, do we also have to salute?" Han Sanjiang felt that every time he saw someone, he had to bow down and bow down, and he had to bow down all the way, and he was a little worried.

Saburo Sasaki replied with a smile: "No, you are not Japanese, you can visit as you like, you can go wherever you want, without constraints! We just haven't seen each other for a long time, so we salute like this!"

I heard Saburo Sasaki say that you can visit casually, so Han Sanjiang, Jiang Yuanqiao, and Fang Xinyue each went to visit those CNC lathes.

Han Sanjiang came to the place where the stop valve was made on the left side of the front, and took a closer look, in front of the head of the CNC lathe, there was a panel on the upper inclined plane that was the same as the TV screen, and the screen of the panel flashed with numbers, and in the square screen more than a foot wide and more than a foot long, a string of numbers kept changing, and below the screen was a large board of electric key buttons, all of which were English letters, and some program codes.

Han Sanjiang stood next to him and looked at the turning tool in the transparent glass oblique cover, constantly turning, spraying copper chips like a shower, after a while, the boring knife retreated longitudinally, the lathe "buzzed", only to see the knife holder flicked, "click", another round knife outside the car, ready, less than two seconds, on the "beep" sound, issued the next command, the numbers on the screen followed the continuous beating, the turning knife "woo" After a while, after the turning is completed, the outer circle of the car retreats horizontally, making a "buzzing" sound, and returns to the return path of the tool holder, that is, the original coordinate position of the tool holder.

I saw that the knife holder was flicked, the outer circle knife changed a direction, and another pointed conical knife appeared in the turning position of the tool holder, and with a "click" sound, the sharp conical knife was fixed, and the numbers on the screen moved and jumped again.

Three seconds later, with a "tick" sound, the pointed conical knife was sent to the reference point of the product, and after only a second of pause, the computer screen kept changing, and a string of turning thread codes appeared on the screen, and then the cone-like knife went to the outer circle, unexpectedly, the turning was not an outer circle, but a thread, Han Sanjiang's eyes widened, how could this knife turn out the thread, and what is the principle!

He suddenly couldn't believe that this was true, this CNC and tricks, the thread three under five divided by two out of the change, seeing that it was the turning action that went in, what came out was the thread, after three turning, the thread has been turned, and the external thread process of the entire globe valve was completed.

The machine exited the operating program, and with a long beep of "woo~", the numbers on the computer screen stopped beating, and the upper right corner of the screen lit up with a red signal light.

The operator opened the glass shield, took out the product in the flange with a tool, and placed it in the plastic square shallow box where the product was placed. Then from the square plastic shallow box where the blanks are stacked in front, remove the blanks of a globe valve in order, put them in the flange, and lock them with tools.

Han Sanjiang didn't rush to see the product, he looked into the lathe, and saw that the whole lathe was empty, the track was the movable knife holder, the bottom was empty, the whole lathe was blocked by iron plates, and the things inside could not be seen, the copper chips had fallen into the copper chip box below, there was no copper dust attachment on the track, it looked clean, and after a closer look, it turned out that the back and front of the knife holder were equipped with automatic cleaning protective sponge body, and the lathe was always wiped beautiful by the sponge body.

The worker put the product, pull the glass shield, press the work button, the lathe will automatically operate, "hum" sound, work step by step, the whole process only takes five minutes, and the external thread processing process of the globe valve is completed.

Han Sanjiang came to the finished box, took out a finished valve body, looked at the full outer teeth, the smooth and bright inner hole, except for exclamation, he could not say any other words to describe Han Sanjiang's mood at this time. The product not only has a smoother finish than it is made manually, but also the thread is flawless, just like the natural formation, to the extent of flawlessness, and the product quality is simply impeccable.

Han Sanjiang thought that he was the smartest person in the world, but seeing that this thing could be made by himself without a human being, and the thing made was flawless, he knew at this moment that he was just a relatively intelligent person in a primitive society, and this Japanese technology has reached a world-famous level, which is simply a world of difference in comparison.

Jiang Yuanqiao was also shocked, what he saw was the process of molecular processing, this is a CNC drilling machine, there is a good molecular device on the drill platform, an umbrella-shaped cylinder with a 30-degree inclined plane on the top, wide at the top and narrow at the bottom, one-third of the inclined plane is larger than one-third of the cylinder below, the inclined plane is also one-third long, and the place where the lower cylinder is handed over is also a small inclined plane, and the middle of the cylinder below has been bored, which is a hollow material.

The molecular apparatus inserts several condensing capillaries into this inclined plane and separates the cold air through a link with the cylindrical hole below. Therefore, the small hole of the same size and evenly distributed is made on this inclined plane, the inner hole of the small hole is only 0.8 mm in diameter, and the outer hole is only 3 mm in diameter.

0.8 mm hole, through the drilling machine automatic punching, a needle-like drill bit, into the depth of 18 mm to 20 mm of oblique hole, 30 degrees of angle into it, first of all, copper chips are difficult to get through the 0 · 8 mm hole, the drill bit in the long time will be hot, heating is easy to cause the center distance deviation, and then the drill bit is broken in it, as long as the drill bit is broken, resulting in the whole product will be scrapped, this thing I have done, is a breath down, can not be ventilated halfway, a ventilation drill bit will be broken. I've been doing this for half a year, and there are not many people in the factory who can do it, so it's a technical job.

Jiang Yuanqiao watched the drilling machine slowly drill in, the drill bit kept rotating, a small pipe sprayed white mist on the tiny needle-like drill bit, it could be something like coolant, and a hole was planted in less than four seconds, and then the second one was played, and the drill bit kept playing, and no problem was found. Just such a shunt was completed in less than five minutes!

If you want to do it manually, it is difficult to do it without the best technician, and even if you do it, it will take 20 minutes to breathe and regulate his breath before you can do it one by one. Therefore, it is a big problem to make separators while making air conditioning products! I didn't expect it to be easily completed here in Japan. That guy did it effortlessly, and I have to admire the Japanese for opening their brains.

Fang Xinyue walked in the workshop, watching the digital transformation of each type of numerical control, silently noting down the computer program and code exchange, especially when turning threads, she remembered the set of codes firmly, and silently wrote down their data from the reference point and original coordinates of the x, y axis. It can be said that this trip to Japan fulfilled her wishes. It turns out that Japan's technology has long been at the forefront of the world in terms of computer code writing, which shows that the Japanese have become a world-class country in terms of computer language, and they have already popularized these things, and the technology is very mature.
