In City H in December, winter came a little early.
At seven or eight o’clock in the evening, the temperature dropped and was already close to zero degrees. Especially in the past two days, it suddenly rained and the temperature was even lower, reaching zero degrees.
For the citizens of City H, this **** weather is really cold.
To the east of the West Lake, in the Jiuxi Rose Villa Garden, there is a special villa, which is also the villa king of the villa area. It is the home of Mu Yang, the richest man in the world.
At this time, the central air conditioner in the villa has been turned on, and the indoor temperature is controlled at about 22 degrees Celsius, which is separated from the outdoors into two different worlds.
“Husband, don’t continue to feed Xiaofan, maybe he is already full. ”
Song Xuelu, who was sitting on the sofa, hugged her daughter and reminded Mu Yang at the dining table.
“Hey, I really didn’t pay attention until you reminded me. I finished eating a small bowl of rice porridge.” Mu Yang looked at the muddy rice porridge in the bowl, and his son had already eaten it.
He fed his son spoonful by spoonful while thinking about things, but he really didn’t notice this.
Suddenly, Mu Yang forgot one thing, his son ate two small bowls, and looked at Xiaofan’s bulging belly, and said apologetically, “Honey, Xiaofan ate two bowls of rice porridge. .”
He was feeding the children in the restaurant, and his wife and family didn’t pay much attention to his situation. Remember the URL m.xbequige. com
Hearing Mu Yang’s words, Song Xuelu was speechless: “Ah, why are you feeding so much, one bowl is enough.”
After finishing speaking, he hurriedly put the daughter in the mother’s arms, came to check the son’s belly, and found that it was round, but luckily it was not serious, I was afraid it would be broken.
“I saw him eating and feeding, thinking he was still hungry. Seeing his wife’s worried look, Mu Yang knew his problem, “It should be fine, just two small bowls.”
“He’s only very young, so he needs to eat less and feed more. It’s really unreliable for a big man like you to take care of children.”
“Hey, yes, yes, pay more attention next time.” Now Mu Yang was really worried, pinching his son’s face and said, “Next time I’m really full, can you make a sound, and it’s fine if you don’t cry.”
“I guess it will be a few months. It’s too early to talk. The child is either hungry or wants to **** when he cries. Don’t keep stuffing him in his mouth. He probably doesn’t even know that he is full.”
“Full, full.”
A soft voice shouted from Mu Fan’s small mouth, Mu Yang heard it, and he was very pleasantly surprised: “Honey, Xiao Fan is full!”
“Isn’t it normal to be full after eating two bowls?”
After Song Xuelu finished speaking, she realized where the problem was, and was very pleasantly surprised.
“Eh, yes, I heard that too, but I didn’t speak very clearly.”
Mu Yang was also very excited: “Hey, my wife, my son can talk, my son, call me papa?”
“Ma, Ma Ma.”
Xiao Fan in Mu Yang’s arms stared at the two familiar adults with wide eyes, as if he was encouraged by something, he also became excited, and his little mouth moved.
“It’s Papa, not Mama.” Mu Yang corrected.
Xiao Fan still shouted: “Ma Ma, Ma Ma.”
When Song Xuelu heard her son shouting, she wept with joy, she really didn’t hurt him for nothing.
“Honey, this kid is not good, he must be playing tricks on me on purpose. ”
“What does a child know, it should be called Ma Ma, who told you that you don’t have much time with him.”
Song Xuelu snatched her son, and then coaxed him to continue shouting “Ma Ma”. After being hit, Mu Yang went to find her daughter, who said that she was closer to her father.
As a result, the girl still couldn’t speak, and still babbled, not knowing what the adult in front of her was playing.
Mu Yang’s parents and mother-in-law knew that Xiao Fan could call Ma Ma, so they also tried to teach him to say “Grandpa”, “Grandma” and “Grandma”, but in the end, he could only say “Ma Ma”, and occasionally “I’m full”.
Xiaofan can call Ma Ma, and the whole family is very happy, which means that the child has grown up a big step.
Some children can’t speak at the age of one or two, and parents are very worried. They are really afraid that their children are dumb or have mental problems.
so,
From a woman’s pregnancy to the birth of a child, she can talk, grow teeth, walk normally, go to school, and get married. In the past ten or twenty years, parents have poured in so much energy.
Raising a child is really hard.
There was a happy event at home, and Mu Yang continued to invest in the research of CNC machine tools in early December.
And it is the peak among CNC machine tools, that is:
Five-axis linkage CNC machine tool!
Some people may ask, what is the difference between CNC machine tools and CNC machining centers, and what is five-axis linkage?
CNC machine tools generally refer to processing properties such as turning, milling, boring, drilling, grinding, punching, and cutting.
The CNC machining center generally refers to more than two processing properties, generally including turning, milling, boring, drilling and other processing properties, with automatic tool change function.
Others, such as grinding centers and turning and milling centers, are also considered machining centers, but they are more inclined to CNC machine tools with turning, milling, boring and drilling functions.
What Mu Yang wants to research is the five-axis linkage CNC machining center, which has the processing functions of turning, milling, boring, and drilling at the same time.
So what is five-axis linkage?
Is a five-axis machine tool a five-axis linkage?
totally different!
The difference is huge.
Five-axis linkage means that there are at least five coordinate axes (that is, three linear coordinates and two rotational coordinates) on a machine tool, and they can be processed simultaneously under the control of a computer numerical control (CNC) system.
The linkage here refers to the coordinated movement of the five axes, which is very critical and the core.
Otherwise, it would be too easy to develop five-axis, seven-axis, and nine-axis. Isn’t it just adding guide rails and motors? Adding a guide rail means one more axis, which has no technical content.
Therefore, linkage is the key, and it is necessary to ensure accuracy and high speed.
Where is this five-axis linkage used?
What processing problems are mainly solved?
In a word, complex spatial surfaces!
Therefore, five-axis linkage CNC machine tools are the only means to solve the processing of impellers, blades, marine propellers, heavy-duty generator rotors, steam turbine rotors, large diesel engine crankshafts, etc.
It has a decisive influence on a country’s aviation, aerospace, military, scientific research, precision instruments, high-precision medical equipment and other industries.
Without it, it is difficult to machine curved surfaces.
A curved surface processing is difficult for all traditional processing methods.
At the same time, due to the reduced number of clamping, the machining accuracy is higher.
Why do you say less clamping times means higher precision?
This is because every time the workpiece is installed, the clamping reference may be different, or the position of the placement may be different. This is a bit like Mu Yang doing the eighteenth set of radio gymnastics. It is difficult to ensure that the depth and strength of each drilling are the same. , even if the pore size is the same.
Therefore, the importance of five-axis linkage CNC machine tools is presented.
In fact, Xinghai Group’s metal 3D additive processing is easier to realize if the precision requirements are not high and the batch size is not large.
If Xinghai Group’s metal 3D additive technology has higher precision, faster efficiency, and the material performance of surfacing welding is the same as that of high-quality forgings, then what kind of five-axis linkage machine tool is used, without secondary processing, and directly eliminates turning, milling, and drilling? , Boring and other processes, one-step processing in place.
Therefore, the importance of Xinghai Group’s metal 3D additive equipment can be imagined. As long as the accuracy requirements are not strict, it can be processed without five-axis machine tools, which is a blow to dimensionality reduction.
Recently, some international giants have offered 50 million yuan to buy Xinghai Group’s metal 3D additive equipment.
That’s right, 50 million, the unit is US dollars!
Just like when Huaguo wanted to spend 100 million US dollars to buy advanced five-axis linkage CNC machine tools for foreigners, they couldn’t buy them yet, and they were restricted by the beautiful country.
Capable of processing at the forging level, the roughness and efficiency are fast, and the metal 3D additive equipment of Xinghai Group is two grades more advanced than the international counterparts.
Mu Yang also knows the importance of his company’s metal 3D additive equipment. Since the start of the OEM business, the company has been very cautious in accepting orders from foreigners.
Any order will be accepted.
Moreover, recently, many high-level companies have been rejected to visit, such as the domestic Platinum Company, international giants Four Star, Caterpillar, Mitsubishi Heavy Industries, Alstom and other companies.
It also refused to visit the relevant departments of Shili, unless the leader of Shenghang came over.
As more and more people want to visit Xinghai Group’s metal 3D additive equipment, and even want to find a relationship with the leader of H City, Sheng Shi, Xinghai Group’s security team also arrested more than a dozen secret agents, and these leaders only knew about it. The importance has been equal to the industrial master machine.
The security team of the Xinghai Group is not those ten-year-old guards, but veterans. After wearing the luxurious equipment of the Xinghai Group, their combat effectiveness has risen to a higher level. Even if they can’t hold guns, their combat ability is very fierce.
In fact, the Xinghai Group’s protection system is not a human, but an intelligent security system. When outsiders enter the Xinghai Group, they have already been monitored.
Even if the security team misses it, they cannot enter the intelligent security system with layers of protection. The more important laboratories and workshops, the stricter the security.
Normally, employees can enter and leave the laboratory and workshop at will, but the situation is completely different when it comes to outsiders, and it is too difficult to get in.
Of course, in any case, metal 3D additive equipment still cannot replace the five-axis linkage CNC machining center in some fields. After all, metal 3D additive equipment still has many limitations, such as higher roughness and precision requirements, and higher requirements for forgings. More demanding workpieces still rely on five-axis linkage CNC machining centers.
Xinghai Group already has the ability to manufacture high-end CNC machine tools, which is not difficult for Xinghai Group, which has strong machining capabilities and top automation technology.
However, it is still quite difficult to build a five-axis linkage CNC machining center.
Mu Yang has bought the technology of CNC machine tools and has enough understanding of CNC machine tools. If he only manufactures ordinary five-axis linkage CNC machining centers, there must be no problem.
He doesn’t have to have a super-large processing range, and he will start a super awesome black-tech five-axis linkage CNC machining center when he comes up, but Xinghai Group has already laid a solid foundation to build a top-notch five-axis linkage CNC machining center.
If it is researched normally, Muyang can also make it, but it is too time-consuming, not a few months, but after it is manufactured, it will take a long time to verify optimization and improvement, not two or three years before and after.
Maybe for Shen Yang machine tool, not to mention two or three years, the top five-axis linkage CNC machining center will be produced in ten years.
Or, even for the island country MAZAK Yamazaki Mazak, an international leading enterprise of five-axis linkage CNC machining centers, it is quite remarkable to be able to produce a new top five-axis linkage CNC machining center in two or three years.
But two or three years is still too long for Mu Yang.
He doesn’t have so much time to spend on the five-axis linkage CNC machining center, and he still has more cutting-edge technology waiting for him to conquer.
Therefore, if you can open it, you can open it, and directly use achievement points to purchase mature technology from the reading system.
He now has more than 2,000 achievement points, so he doesn’t have to worry about achievement points.
Opening the achievement point store, I spent a lot of time browsing, and found a five-axis linkage CNC machining center technology that is more suitable for Xinghai Group, and it is also a general-purpose type.
If it is a special type, it will not be used after it is made, or the frequency of use is not high.
If it is a basic universal type, it can meet most of the company’s workpiece processing, and can meet most of the market demand at home and abroad.
After mastering the general-purpose equipment technology, it is easier to delve into other styles of five-axis linkage CNC machining centers on the basis of its technology.
The world’s top level, about 4-10 years ahead of the most advanced technology in the current laboratory, required achievement points: 150
A technique requires 150 achievement points, which can be said to be the most expensive technique since Muyang’s rebirth.
After a while, Mu Yang absorbed the new technology, and then remained silent for a long time to see if there were any different gains.
“If there is no metal 3D additive equipment, Xinghai Group really can’t manufacture this universal five-axis linkage CNC machining center!”
This equipment is different from the conventional five-axis linkage CNC machining center in structure.
For example, Muyang’s new technology workbench has an additional cooling system compared to conventional CNC machine tools.
We all know that precision machining of workpieces, due to the friction generated by the cutting tool, the temperature of the workpiece processing surface and the tool surface is very high. Generally, coolant is used for cooling, and part of the heat of the workpiece will be transferred to the worktable.
But even if there is coolant, the surface of the workpiece and the temperature of the workbench cannot be cooled down all at once.
Processing produces internal stress, and high temperature also produces internal stress, and thermal expansion and contraction, so the size of the workpiece requiring precision machining must be inaccurate.
Therefore, for workpieces that require finishing, the cutting amount is very small. One is afraid of the size being affected by excessive temperature, and the other is afraid of internal stress during processing.
Muyang’s new technology is not without a coolant system, but more subtle. At the same time, there are small winding holes inside the structure of the workbench. These small holes cannot be processed by conventional processing methods.
The small hole is the cooling system, which can cool the workbench through coolant.
The small holes are not large enough to seriously reduce the structural rigidity of the table.
Perhaps, this workbench cooling system looks rather weak, but it can reduce the weight of the workbench without reducing the rigidity much. At the same time, we try our best to reduce the processing temperature of the workpiece, thus affecting the deformation.
The table will also rotate at high speed. If the weight is too large, the inertia will be very large, which will affect the accuracy, and the reduction gear will be easy to wear.
In addition to the workbench, there are many parts that are very cleverly designed.
“Niubi! The design is so exquisite, I really want to design it, I really can’t think of it, the system is Niubi!”
Mu Yang couldn’t help but praise the system. At the same time, he was secretly fortunate that Xinghai Group had metal 3D additive equipment.
It seems that if there is no solid foundation, no qualified materials, and no advanced processing methods, even if you have advanced technology, you will not be able to make it!
In other words, if the hardware could not keep up a few years earlier, the CNC system might not meet the requirements.
In addition to the ingenious design ~ www.mtlnovel.com ~ the hardware requirements are also harsh.
Just like the workbench just now, his five-axis linkage CNC machining center can control the displacement within 1 micron (0.1 wire, 0.001 mm) when the workpiece is processed with a load of 100KG!
Compared with the world’s top products with similar processing ranges, such as the Mori Seiki NMV5000DCG, experimental concept products that cannot be mass-produced, carry the same force, and the displacement is estimated to be 2 microns to 5 microns. This difference level is large, not a grade.
“If my five-axis CNC machining center is manufactured, it will probably be the world’s number one.” Mu Yang was a little excited. He had never seen the world’s top five-axis CNC machining center, because he couldn’t buy it or touch it. arrive.
But Mu Yang believes that his five-axis linkage CNC machining center is faster, more stable, and smarter than any other manufacturer’s product with ultra-high rigidity, ultra-high precision, and ultra-high speed.
