1144 Heavy Weapons of Great Power (4) (6th Update)
"Nine axes and five linkages? Isn't this several levels higher than five-axis linkage? The old man's eyes suddenly lit up.
At first, Yun Fei was still modest!
For the old man who does not know how to CNC machining center, Jiuyi Heavy Industry has changed from the beginning of the two-axis CNC lathe to the three-axis two-linkage CNC milling machine, and then the three-axis three-linkage machining center, and the four-axis four-link machining center...... They are all rising level by level, and the nine-axis five-linkage is four more movement axes than the five-axis five-linkage!
If this is not advanced enough, what can be considered advanced?
"Old man, this can't be understood in this way. There is nothing wrong with this is a nine-axis five-linkage machine, but this is just a concept machine, and it is only used here for experiments. In fact, a lot of the movement in this is done useless work, processing this aircraft wings, five-axis linkage machining center has no problem. If the conditions do not allow, the use of gantry three-axis machining center and tooling, in addition to more processes, the position is poorer, it can also be processed......" Sun Lin explained to the old man with a wry smile.
"Isn't this possible for mass production?" The old man was a little puzzled.
Isn't this a joke on his old man?
"Not really. It's just that the control system in this is not a set of numerical control systems, but three different sets of systems to control different parts, and then integrated control through the powerful supercomputer of our research institute, that is to say, this program is read by the supercomputer, and then fed back to the control system......" Sun Lin's explanation made everyone dizzy. This one is too complicated.
"Isn't there a way for you to control with just one CNC system?" It was still the old man who didn't know his name asking. Since the computer can be used to carry out segmented control, it can be completely transferred to the numerical control system.
"That's the biggest problem. Our own CNC system control the five-axis linkage is relatively reluctant, and there is often a delay, resulting in the problem of reduced machining accuracy. In order to produce such a device, it is necessary to have a numerical control system that can control nine axes of motion. At present, Germany is the only country in the whole world that has such a system, and the United States and Japan may have it, but they have not heard of it. The five-axis and five-linkage equipment can fully realize the precision machining of most parts. More axes are basically useless......" CNC machining center, five axes and five linkages are basically the top.
It's not that the more axes of motion there are, the more advanced they are.
There are many axes of motion, and it is almost something that is researched to produce a specific product. For example, in Yunfei's original world, Huaqing University has developed a nine-axis and five-linkage machining center for processing propellers, with a total of several spindle heads, each of which processes a blade......
It's fine with propellers, but it's not okay with anything else.
These are all very frustrating technical research directions.
Of course, it does not mean that the five-axis and five-linkage in the CNC machining center are the top, and there are more advanced things, that is, the ultimate direction of CNC machine tools - industrial machines! This industrial machine is not the kind of machine that can only make simple movements that are most common in those automobile production lines!
Due to time issues. The crowd didn't dwell too much on it.
The Jiuyi Research Institute said that they have no way, who can guarantee that they can provide a supporting control system? There is no way for people to have the top computer experts in China and the Soviet Union, what can they do?
As for who were the top experts in the Soviet Union?
Isn't that a joke? Tanalia, Vissarionlovich, these experts from the former Soviet Union, if not the top, might be in charge of one aspect of research in the Jiuyi Research Institute? None of them are the top experts, how can the Jiuyi Research Institute obtain such results?
Even if they don't, as long as they have these results, they will become the top experts. In China. This kind of thing is too normal, too normal.
"Such a small machine is worth more than 10 million?" The old man obviously didn't expect that the five-axis linkage machining center provided by Jiuyi Heavy Industry to Factory 132 and North Heavy Industry to these units looked very large from the outside. But not as big as those gantry machining centers!
Yun Fei is clearly the money of the country.
"Old man, this is a five-axis machining center. The spindle can swing forward, backward, left, right, and next to it is the fourth axis, which is responsible for rotating the workpiece. The circular workbench below is responsible for moving back and forth...... "For the price of this thing with five axes, Yun Fei has no choice. "It's not that the price of this device itself is high, it's that the price of this series is high. Old man. If you look at this process, you can see why it sells for such a high price. If a three-axis machining center is as common as it is and can be produced by ordinary companies, it won't be worth much. Originally, when we could not produce four-axis in China, the Germans dared to sell us a four-axis linkage machining center for two million dollars! How much is it now? After we can produce it, the price will be 4 million yuan, and the US dollar will be less than 500,000 yuan......"
Yun Fei's meaning is obvious, what we sell is not equipment, what we sell is technology, what we sell is production capacity, and market opportunities. It can even rise to the top of the country's chances of survival.
Who said that if there is no such thing, there is no way to mass-produce a lot of strategic equipment?
Before there is no four-axis linkage machining center, the annual production capacity of Dongfeng 31 in China is estimated to be no more than five! Lao Maozi is the most obvious, such a huge industrial base, the ability to produce Topol-MD missiles per year will not exceed twenty, this is because their country's CNC machine tools China is still lagging behind......
A lot of parts require super high precision, and if it is only produced by hand, that efficiency can be imagined. It's like a horse-drawn carriage compared to a train.
"This one, the processing is the blade of Xinkaixing Impeller Factory, the spindle speed is 24,000 revolutions per minute, the moving speed is 85 meters per minute, it is a high-speed machining center, the processing efficiency is about 40 percent higher than the four-axis, and the accuracy is 20 percent higher...... "Sun Lin pointed to a five-axis machining center that is processing gas engine blades, this thing is processed with five axes, compared with the four-axis machining center, the efficiency is much higher.
This machining center is different from the large gantry machining center next to it, the processed parts rotate faster, the spindle does not swing left and right, but keeps moving up and down with the flip of the parts, and always keeps the distance between the apex of the ball cutter on the spindle and the parts, so as to avoid the phenomenon of hitting the knife or over-cutting imagination or something......
"This doesn't seem to be any different from those quadaxes next to it, right?" The entourage of the visitor pointed out that this is a four-axis linkage machine tool. Although the rotating fourth axis can be moved successively or even up and down, and the hydraulic center behind it can also follow up synchronously, it is essentially a four-axis.
"At present, this equipment is only testing the rotary positioning accuracy of the rotating shaft. It is perfectly sufficient for the blades to be machined with a four-axis machine, as this is only the simplest three-dimensional twisting surface. This batch of blades was specially mobilized from Xinkaixing Turbo Factory to test the reliability and machining accuracy of our five-axis machining center...... "Sun Lin directly filtered out any bad intentions in these words.
The main role and main work of the test workshop is to implement these integrated machining centers, not all equipment can use all the functions of any part of the machine.
"Wow......" When they saw the things being processed on three consecutive machines that were exactly the same as this impeller machine, many people exclaimed!
These three machining centers are actually carving human heads! And the soft display on the modeling programming computer next to it, this avatar is actually the old man's avatar!
It's just against the sky.
"This is to test the processing ability of these machine tools, and at the same time, our boss wants to give the old man a gift, so he directly uses our machining center to carve the old man's head......" Sun Lin's explanation immediately shocked everyone.
I have never heard of such a thing as carving a human head with a machine tool! And now, they actually saw it with their own eyes.
The most difficult part of this is not to carve out the shape. It's that people's facial expressions are very vivid!
"This is the use of the latest aviation duralumin jointly developed by the material factory under the North Heavy Industry and the material factory under the 132 factory. In order to obtain the test number, the three machining centers used different materials, namely TC4 titanium alloy, which is a difficult-to-machine material, H62 brass with good processing performance, and this aviation duralumin ...... that has been being finished.
The first time the old man inspected Huadu, Yun Fei gave the old man an ordinary aluminum plate carved with very artistic characters in the processing center, and this time, Yun Fei simply used the processing center to carve the old man's head!
"The most difficult part of this is to process the facial contour part, because this part of the tool must constantly use the swing angle, so as to meet the requirements of the model, and there will be no place to process because the angle is not enough, and it will not produce the same overcut phenomenon because the angle is not enough...... "Few people who visit are professional, Sun Lin will naturally introduce the difficulty.
Then everyone follows his tips to see if things are really like this, and it is easy to understand why the five axes are so powerful.
The five axes are far more powerful than most people think, a lot. (To be continued......)
