"Don't think about mirror turning, even if we can get such a precision equipment lathe from Switzerland or Germany, we can't get it without millions of dollars. (Please search, or enter directly to see the latest chapter) I think that such a device can only be processed by using a grinding machine for the final fine grinding......"

For large pure tungsten parts, except for those companies that specialize in production, the general processing plant rarely comes into contact with such materials.

This is a hard and difficult material, not because this material is too hard, but because the main component of most of the world's metal cutting tool materials is tungsten, which is like using a knife to cut against a knife, even if the best forging process is used, the knife produced even if it cuts other components are similar, and the knife with different production processes will roll or break the edge.

The tool is not wear-resistant, and it is a very painful thing to process any material.

Fortunately, in the general cutting tools, not only tungsten element, but also a small amount of cobalt used as a binder and other titanium carbide to improve the toughness of cemented carbide, tantalum carbide to improve hardness, wear resistance, heat resistance, etc., which causes the tool used for processing to have better wear resistance, hardness and impact resistance than pure tungsten products sintered at high temperature and high pressure, so that the processing can be realized.

"Grinder? Master, where can you find such a heavy grinder? That's just a difficult thing to do! "It may be possible to find a cylindrical grinder that is so large, but it is too difficult to find a large and heavy-duty grinder that can clamp a total weight of more than 600 kilograms with workpiece and tooling......

"It's not to find a grinding machine, but to design a grinding device mounted on the top of the tool holder, and finally grind the outer circle and inner hole repeatedly with the rotating grinding wheel of the tooling......" The master's words suddenly made Yun Kai's eyes light up.

This is indeed a proven approach.

I still see too little.

"The grinder installed on the top of the tool holder adopts the flexible connection of the belt, and directly connects the grinding wheel with the motor with a belt, so that the grinding wheel will not be broken because the load is too large, and the diamond grinding wheel must be used, otherwise the ordinary corundum or silicon carbide grinding wheel is not very effective for such a hard material, and the grinding wheel will wear very quickly, and the quality ......cannot be controlled."

Listening to the master's analysis, Yun Kai kept nodding.

There is an old man in the family, if there is a treasure, the ancients will not deceive me!

"Master, you're not busy this time, are you? Why don't you help me get this out? "Yun Kai immediately hit the snake with the stick, the master and their more than ten masters in the internship factory, six or seven of them are special technicians!

It must be much stronger than the level of his own half-ass.

"It's such a simple thing, you can do it yourself, and it won't take much time......" The master's small eyes widened, this kid is too good at beating snakes with sticks, right?

Why didn't it happen before?

"Master, this is really not complicated, the time for this batch of work is very tight, only three months......" Yun Kai squeezed out a sad look on his face, and sighed at the master.

"Isn't it, boy? With such a difficult job, how can you give it half a year, right? Guo Guichuan was shocked.

This kid can't have a burning head, right?

Yun Kai was speechless, could it be that he told Master Sù that the construction period was indeed half a year, but he drilled out an intelligent assistance system from the next 20,000 years in his head, and asked himself to complete this task in three months, otherwise he would wipe himself out!

"When I took the job at that time, I only saw that the profit was high, so I didn't think much about it......," Yun Kai scratched his head and explained.

"Okay, I'll discuss it with Lao Xiao, there are general materials in the workshop, and after we choose the model, we will tell you, you can go to Wanguan or Jinfu to buy it yourself, and strive to do this well in half a month......" Guo Guichuan could only scratch his head helplessly.

From the late nineties of the twentieth century, after being transferred to the internship factory as a practical teacher, he himself does not remember how many students he brought out, and even more students who won big prizes in the national skills competition, but few people still remember to call him as a master after going to work to say hello or something, and there are even fewer who often come to see him.

There are not many students and apprentices in Rongcheng, and even many of them have entered the subordinate factories of the Aerospace Group, and when they meet them halfway, some of them will say hello, and some will even pretend not to see them. Of course, if there is anything that needs to be found by Guo Guichuan, not only will he call, but he will also have to come to the door.

Respect for teachers, that has become a legend.

Yunkai is an exception.

Even if I work far away, I will make a phone call to chat with the master every once in a while. Usually, from time to time, I shout at a few masters and go to the farmhouse outside to have fun or something.

Therefore, Guo Guichuan still attaches great importance to Yunkai.

Yun Kai's request was not excessive, and he would not refuse.

It's just a matter of taking some time anyway.

As a training teacher, the most important thing is time. And such tooling, the difficulty of processing itself is not too high, most of the parts can be processed by those apprentices, except for the last one used to install the rotating shaft, the two bearing holes that require high coaxiality, there is no other problem.

"Okay, master, why don't we invite Master Xiao and them out for two drinks at noon?" Although it is the master who asks for help, he should not show it less.

"Let's go and get busy with you first, you can eat and drink, you can do it at any time, there is a national skill competition within the system in August, and the training will start today, I can't leave with you Master Xiao......" The master shook his head at Yun Kai.

"Alright then, master, I'm sorry for you!" Yun Kai didn't force it anymore, from the beginning to the present, he never mentioned money.

He knew that if he offered money in front of the master, the relationship between the master and apprentice would suddenly change.

In these days, there are many things that cannot be measured by money.

In particular, Yun Kai also knows that he is a master and is not short of money. Not to mention that his salary and bonus are not low, just the monthly rent of the three houses they rented out is enough for their old couple to live. Moreover, the daughter of the master's family has also become a family, and she has set up a small advertising company in Dudu, so she doesn't need subsidies from the old couple at all.

The problem of processing technology has also been solved, and whether it can be processed can be clearly understood only after trial processing.

When I left the internship factory of the Aviation Academy, it was already half past ten, and even if I went to the rented plant, I couldn't do anything, the office there had to be cleaned up, and the placement of the equipment had to be planned, otherwise all the equipment had to be reinstalled when the equipment was to be added in the future......

In addition, on the floor of the factory with a hardened thickness of more than 20 cm, in order to maintain the stability of the equipment when running, it is necessary to drill the installation holes of the anchor bolts......

These things have to be done before the equipment is shipped back.

However, you have to find a professional person outside to do this, which is not to say that you can't do it yourself, but without professional tools, not only the effect is not good, but also the entire hardened ground will be damaged.

Called Li Lu, she was running the company registration, and she didn't even go to Longguang to handle the resignation, Yunkai sued her yesterday, and her company name is Xingmeng Precision Machinery Co., Ltd.

The business scope is equipment design and manufacturing, mechanical parts processing, equipment maintenance, tooling and fixture design and manufacturing, etc.

I'm worried that the second sister and a few children are not suitable for life here, and I'm also busy with things in the past two days, so I just go to the second sister's side first, and I have to find a way to help the three children contact the school, and I will definitely find Zhao Ling to help with it later.

Although Yun Kai has been here for a long time and knows a lot of people, he has no relationship with the education system. The only thing that can have a relationship is the aerospace school, which is not easy to get into. Other schools that are easy to get into are too rubbish, many of them are schools for the children of migrant workers, and the quality of education cannot be compared with these schools at all.

For city life, Yun Su really didn't show any inadaptability, perhaps, in a person like her, what kind of life is the same.

"Stand up for me, see what you look like? Good introspection! When Yun Kai arrived at the Starlight Garden, Yun Su was letting the three children stand in a row in the living room.

"Second sister, what's wrong with them?" How Yun Su educated three children, Yun Kai really didn't know, anyway, when it came to educating children, he knew nine out of ten - he didn't know anything.

"I grabbed the TV last night, and I grabbed the computer this morning, and I broke the keyboard...... Yun Su was angry.

"What?" How could these bear children do such a thing?

"You guys, what's going on? Why grab something? If you don't go to school for these two days, you can't read a good book? "Today's children's bear children are no strangers to computer gods.

In my hometown's school, computer courses began to be offered in the fourth grade of primary school, although the level of those teachers is not as good as that of children, but it is no problem to teach them some basic power to turn on and off the computer or surf the Internet.

"Kaiwa'er, why don't you move here too, here, I can't control them......" Yun Su was not polite to Yun Kai at all.

Women always need a man to rely on.

If her husband can't be trusted, she can only rely on her younger brother.

Yun Kai, but the man of the Yun family!

"I can't live here at all......" Yun Kai shook his head depressedly.

Even if you move here, you will be in the workshop most of the time......

"Why can't you live? Let Xiaoying and Xiaozhen share a room with me, wouldn't it be fine? Doesn't the child have to live in school after he goes to school? Besides, if you live outside by yourself, it's not okay to be full or hungry......" Yun Su had already thought about it.
