"Nine axis five linkage"? Isn''t this several levels higher than five axis linkage? " The old man''s eyes lit up immediately.
At first, Yun Fei was still modest!
For the old man who doesn''t know the CNC machining center, from the first two axis CNC lathe to the three axis two linkage CNC milling machine, then the three axis three linkage machining center and the four axis four linkage machining center... All rise level by level. The nine axis five linkage has four more motion axes than the five axis five linkage!
If this is not advanced enough, what can be regarded as advanced?
"Sir, this can''t be understood in this way. This is a nine axis five linkage. There''s nothing wrong with it, but it''s just a concept machine, and here it''s just for experiment. In fact, many of these movements are useless. There is no problem with the five axis linkage processing center for processing the aircraft wings. If conditions do not permit, the gantry type three-axis machining center and tooling can be processed in addition to more processes and poor position... "Sun Lin explained to the old man with a bitter smile.
"Can''t this be mass produced?" The old man was a little confused.
Isn''t this a joke on his old man?
"That''s not true. But the control inside is not a set of numerical control system, but three different systems control different parts, and then through the powerful supercomputer of our research institute for integrated control, that is, everything in this program is read through the supercomputer and then fed back to the control system... "Sun Lin''s explanation made everyone dizzy. This is too complicated.
"Can''t you control it with only one CNC system?" It''s still the old man who doesn''t know his name asking questions. Since the computer can be used for segmented control, it can be transferred to the CNC system.
"This is the biggest problem. Our own CNC system controls the five axis linkage reluctantly, and there are often delays, resulting in the decline of machining accuracy. To produce this kind of equipment, we must first have a numerical control system that can control nine motion axes. At present, only Germany has such a system in the whole world. The United States and Japan may have, but they haven''t heard of it. Five axis and five linkage equipment can fully realize the precision machining of most parts, and more axes are basically useless... "CNC machining center, five axis and five linkage is basically the top.
It is not that the more moving axes, the more advanced.
There are many motion axes, which is almost something researched to produce a specific product. For example, in Yunfei''s original world, Huaqing University developed a nine axis five linkage machining center for machining propellers. There are several spindle heads, and each spindle head processes a blade
That thing has no problem processing propellers, but it can''t be used to process anything else.
These are very important technical research directions.
Of course, it doesn''t mean that in the CNC machining center, the five axis five linkage is the top. There are more advanced things, that is, the ultimate direction of CNC machine tools - industrial robots! This industrial robot is not the kind of robot that can only make simple motion, which is the most common in those automobile production lines!
Due to the problem of time, people didn''t tangle too much.
The 91 Research Institute said that they have no way. Who can guarantee that they can provide supporting control systems? People have the top computer experts in China and the Soviet Union. They have no way. What can they do?
As for who is the top expert in the Soviet Union?
Aren''t you kidding? Tanalia and Vissarion lovic, experts from the former Soviet Union, if not the top, may be in charge of one aspect of research in the 91 Research Institute? They are not the top experts. How can the 91 Research Institute achieve such results?
Even if they are not, as long as they have these achievements, they will become the top experts. In China, such things are too normal.
"Such a small machine is worth more than ten million?" Obviously, the old man didn''t expect that the five axis linkage processing center provided by Jiuyi heavy industry to 132 factory and Northern heavy industry, although it looks very large outside, it is not as large as those gantry processing centers!
Yunfei is clearly the money of the country.
"Old man, this is the five axis machining center. The main shaft can swing back and forth, left and right. Next to it is the fourth axis, which is the moving axis responsible for rotating the workpiece. The circular public workbench below is responsible for moving back and forth... "Yun Fei can''t help the price of the five axis“ The of this equipment is not the high price of the equipment itself, but the high price of this series. Sir, if you look at the processing of this, you can understand why it sells at such a high price. If the three-axis machining center is so common that ordinary companies can produce it, it will not be worth money. Originally, when we couldn''t produce four axes in China, a German four-axis machining center dared to sell US $2 million! How much is it now? After we can produce it, the price will be 4 million yuan and less than 500000 US dollars... "
Yunfei obviously means that we don''t sell equipment, we sell technology, we sell production capacity and market opportunities. It can even rise to the survival opportunity of the country.
Who says that without this thing, there is no way to mass produce a lot of strategic equipment?
Before there is no four axis 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. With such a huge industrial foundation, the annual production capacity of poplar MD missiles will not exceed 20. This is because their country''s CNC machine tools are still backward in China
For many parts with super high precision requirements, if they are only produced manually, the efficiency can be considered. This is like comparing the transport capacity of a carriage with that of a train.
"This one processes the blades of xinkaixing impeller factory. The spindle speed is 24000 revolutions per minute and the moving speed is 85 meters per minute. It is regarded as a high-speed machining center. The machining efficiency is about 40% higher than that of four axes and the precision is 20%..." Sun Lin points to a five axis machining center 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 moves up and down in coordination with the turnover of the parts. It always keeps the distance between the top of the ball knife on the spindle and the parts, so as to avoid knife collision or over cutting imagination
"This seems to be no different from the four axes next to it?" The visitors pointed out that this is a four axis linkage machine tool. Although the rotating fourth axis can move up and down successively, and the rear hydraulic center can follow up synchronously, it is essentially a four axis machine.
"At present, this equipment is only testing the rotary positioning accuracy of the rotating shaft. It is enough to process the blade with a four-axis machine tool, because this is only the simplest three-dimensional distorted surface. This batch of blades were specially mobilized from xinkaixing impeller 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 function and work of the test workshop is to test these integrated machining centers. Not all equipment can use all functions to process any parts.
As like as two peas were being processed on the same machine as the machine tool that processes the impeller, three people were amazed.
These three machining centers are actually carving people''s heads! The soft display on the next modeling programming computer shows that this avatar is actually the avatar of the old man!
It''s against the sky.
"This is to test the processing ability of these machine tools. At the same time, our boss directly used our processing center to carve the master''s head in order to give him a gift..." Sun Lin''s explanation immediately shocked everyone.
I haven''t even heard of carving people''s heads with machine tools! And now they saw it with their own eyes.
The most difficult thing is not to carve the shape. But people''s facial expressions are very vivid!
"This is processed with the latest aviation hard aluminum jointly developed by the material factory subordinate to North heavy industry and the material factory subordinate to 132 factory. In order to obtain the test data, the three machining centers use different materials, including TC4 titanium alloy, which is difficult to machine, H62 brass with better processing performance, and aviation hard aluminum, which is already undergoing finishing processing... "This is the gift prepared by Yun Fei for the old man.
For the first time, when the old man visited Huadu, Yun Fei gave him an ordinary aluminum plate with very artistic words carved in the processing center. This time, Yun Fei simply carved the old man''s head in the processing center!
"The most difficult part is to process the face contour, 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 over cutting due to insufficient angle..." few visitors are professional, Sun Lin will naturally introduce the difficulty.
Then, according to his tips, we can see whether things are really so. It is easy to understand why the five axes are powerful.
The five axes are much stronger than most people think. This is used to carve human heads just to test functions, not for anything else. Only when the head has a very complex three-dimensional structure can the function of the equipment be tested in an all-round way!
