Seeing Bai Shan's red eyes, Bai Hao walked over.

"White ...... Auntie and grandfather? What's wrong with you. Bai Hao didn't know that the person in front of him was his own grandfather, but he felt that this old man was very kind, and he couldn't help but get a lot closer.

Bai Shan wiped away a handful of tears: "My son was also studying machine tools back then, and later died of illness. ”

"Yes." Bai Hao bit his lower lip and thought about it: "Well, I don't study machine tools, I just like to study things that foreigners hide so that we can't use them." At the moment, there are just no good machine tools, and many things can't be made if you want to. So, let's fix the machine first. ”

Bai Shan was amused by Bai Hao's words.

"Very good."

Bai Shan liked his grandson more and more, although it was a pity that he couldn't say it, but it didn't affect him to look at Bai Hao from a close distance.

Bai Shan suddenly asked, "How much money do you have?" ”

"Sort of."

"You seem to like that three-entry yard very much, I'll ask the old guy to help you, I estimate why it will cost 100,000 yuan."

That yard.

Bai Hao's eyes lit up, it was the courtyard three hundred years ago, and the cypress trees in it were three hundred years ago. In the imperial capital, in his own time, a few tons of money could not buy a set of courtyards.

The courtyard of the three entrances, 100,000.

It's not the same as giving it away for free, so why not.

"Yes, yes, but I don't have Xia Guoyuan, I only have a beautiful knife."

"30,000 US dollars, I'll help you say it." Bai Shan had already inquired about it, and suddenly wanted to buy it, not only because the yard was good, but because he found that Bai Hao was digging a hole in the fifty-first workshop to put a safe to hide materials. So it's better to buy that courtyard, because that courtyard was inhabited by a knight hundreds of years ago, and there must be a secret room in the courtyard.

The secret room can be renovated, so that Bai Hao can hide materials, drawings and other objects.

No matter how good the Ninth Branch Factory is, no matter how good the newly expanded new plant is with a few acres of new plants, Bai Hao is also contracted, not his own.

Although Bai Shan is selfless, in the matter of his grandson, he favors his grandson and wants to leave some for his grandson.

Bai Hao was a little moved, but he still wanted to ask Zhang Jianguo's opinion on this matter, as well as the opinion of his new mother Bai Yuan. changed the topic: "Master Bai, there is a big event today, in case my master doesn't hold it up, you can support it." ”

"What's the matter?"

Bai Hao glanced at Catherine, Bai Shan nodded, he understood.

Left behind to receive the people of Fengxi Machine Tool Factory, Bai Hao and others returned to the Ninth Branch.

Seal the door.

A group of people entered the workshop.

Everyone in the workshop, including Guo Fengxian, changed their work clothes as required.

One is running, and a middle-aged lathe worker who Bai Hao doesn't know is operating the machine. Feng Yuchun stood aside with his eyes on, and several people were holding books and pens and constantly recording something.

Bai Hao was about to step forward but was pulled by Catherine, who stepped forward to observe and then stepped aside.

A set of workpieces was taken off the machine, and then Li Dong, who was sitting on the side, got started and began to assemble on the table, and then someone stepped forward to measure.

"The ninety-sixth test machine, the accuracy of the workpiece ......" is a long series of report numbers.

Catherine noticed that there were a foot-tall notebook neatly lined up on the workstation over there.

Catherine said to Bai Hao: "They are making a circular curve reducer, this one is indeed a four-axis, although it is very small, it is indeed a four-axis, and the operation is quite stable." However, your control procedures are too poor, and you need a good craftsman to cooperate to complete the difficult and complex parts. ”

Catherine's yes is true.

The one who came to the stage to operate was a sixth-level worker, not Li Sanpao's apprentice, but Guo Fengxian's own person.

Because ministries also need real first-hand data.

Only then did Feng Yuchun notice that there were people, and they were foreigners.

Walked up to Bai Hao and asked, "Bai Hao, who are these two?" ”

Catherine demanded, "I'm going to take a look at the control system you've prepared." ”

Bai Hao nodded beside him. Feng Yuchun asked the doctoral student to step aside.

Catherine looked at it carefully for half an hour, and then said, "Some of the ideas are very advanced, much better than I expected, but they are not finished. I don't have full-fledged 4-axis control at hand, but I have a 4-axis test system for testing, which I added to the program, so that this hard non-synchronous rotary table 4-axis machine can be used right away, but it can't make difficult parts, it just works. ”

After speaking, Catherine took out a box of three-and-a-half-inch floppy disks from her briefcase, took out four of them and handed them to Feng Yuchun: "This was originally a kind of horizontal four-axis machining center control system that has been eliminated, and I modified some of them for my graduation project after graduating from college." ”

Change, change immediately.

First of all, it doesn't matter who comes, if there is a source code for this kind of thing, it can speed up the research progress of Jingzhao Jiaotong University.

Starting from scratch, with only a bunch of theories and concepts, it has exhausted five doctors to barely come up with a working operation and control system in such a short period of time.

Immediately switch to a new control system and input the machining program of the parts that have been calculated countless times a long time ago.

This time, the biggest advantage is that there is no need for the master to confirm the positioning and accuracy three times in the process of processing, only need to determine the positioning point for the first time, and form it once, and the accuracy is better than just now.

Seeing that the doctoral students were a little uncomfortable, Catherine personally got started.

Li Sanpao beckoned Bai Hao to come out with him at this time.

Out of the door, Li Sanpao said: "Baby, the loss is that you let Lao Wang cast the base, this kind of machine can't be changed to another person, almost a little bit of the machine will get worse and worse, and the guide rail of this bed is really not good, and it will deviate in a year at most." By the way, what does the golden retriever girl do, she is not very old, but she understands it very well. ”

Bai Hao said: "When she came yesterday, no one told your grandfather? ”

Li Sanpao shook his head: "No." ”

Bai Hao said at this time: "The daughter of the beautiful country Haas Company. ”

Li Sanpao's eyes lit up: "You said that Haas who is engaged in machine tools?" ”

"Yes."

"No wonder, true insider."

Guo Fengxian and others just guessed, because Catherine didn't sign up, and Bai Hao asked Lu Qiao to say who it was.

As for Bai Hao's running there overnight, no one asked.

Not many people know about this, and no one has spread it. It's normal for Li Sanpao not to know.

Li Sanpao sighed and told Bai Hao: "Baby, our machine can be used, but things are really not good, many key parts seem to be usable now, and it will be bad after a long time." I'll tell you, the guide rail in Taishan Prefecture is good, let's change it to a better one, I'll tell you about this guide rail, just heard that the big leader wants to help you, we want the best guide rail, and the lead screw. ”
