Chapter 248： Machining center completed (below)

How to verify that the system as a whole is normal? Do you know if you are working on a workpiece?

Guo Tailai saw a very interesting process in the dream of the future. He used a five-axis machining center to process a whole piece of metal into a metal basketball frame. There were baskets and baskets. The finished products looked quite realistic. . Do not

However, the most cattle is the processing process, the machining center has a variety of tool change angles, and even the connection part of the net is very fine. Guo Tailai put this idea and Professor Wang before the start of assembly. It seems that Professor Wang is also very interested. He directly arranged a task for the second brother to let him make the processing procedure of this basketball net ahead of time.

Now there is a whole piece of metal in the five-axis machining center. For the sake of safety, instead of using titanium alloy directly, ordinary steel is used, and the machining process can be started only after the console starts the machining process. king

The professor rushed to nod and the second brother took a deep breath and introduced the metal basketball net processing program from the floppy disk. The 3D image of the basketball net is immediately displayed on the work interface. Rear

A few well-known academicians and professors who saw this process showed their interest in the process. Such a complicated product, the processing must be considered in many aspects, only one workpiece, basically can see the performance of this machining center. With

When the start of the machining button is pressed, the machining axis of the machining center starts to move quickly, and then the table starts to rotate into position. A milling cutter is automatically selected from the cutter head and fixed to the front of the machined shaft for a quick start. eye

Looked at the outside of the metal block is milled into a cylinder, then change the knife and continue processing. A series of movements are very smooth, and the machining positioning is also extremely accurate. What others have seen is the precise cutting of the cutter head. In Guo Tailai's eyes, the error of repositioning after changing the knife is not more than 0.1 micron. This

What does it mean? Guo Tailai is very clear that as long as the positioning accuracy is maintained throughout the machining process, the final machining accuracy of the finished product can reach 0.1 micron. This precision, even at the international level, is also the highest level of machining accuracy. on

The high-precision lathe that Guo Guotai came to do, a wire car with eight knives, and a knife with iron filings. Now this ultra-precision machining center can process at least 80 knives or even 90 knives, and the processed iron filings are thinner than the flaps.

Guo Tailai has no worries about the processing accuracy of a single cutter head. After seeing the positioning after this tool change, Guo Tailai completely let go of his heart. As long as there is no problem with the processing program written by the second brother, then everything is fine.

The second brother did not disappoint the trust of Guo Tailai and Professor Wang. This processing program was written in great detail. Because it is written as a test program, some can do a lot of work, and sometimes even deliberately divide into several different tools to process different angles.

After seeing a few repeated actions, two academicians couldn't help but frown and asked. After Professor Wang whispered, the brows of the two men re-stretched. Indeed, it is for testing, deliberately complicating simple machining procedures. If you can do it with a complicated number of cutter heads, then you can do it without changing the cutter head.

It was just a metal basketball net that looked very simple, but the processing took a whole half of an hour. However, none of the people watching it felt annoyed. They watched the metal basketball net constantly changing their angles in the machining center. They turned into what they expected, and everyone’s hearts were all incomprehensible. Happy. end

After all the machining procedures are completed, the machining axis has been returned, and the cutter head has re-entered the standby state. The red light indicating that it is being processed has turned into a green light at that moment, and the processing is completed. "

Take it out and have a look. "A leader of the Ministry of Information Industry has been unable to hold back and quickly ordered.

The honor of the first piece of work was handed over to the designer of the machining center, Professor Wang. In this regard, no one has any objections and is expected to return.

"Don't wear gloves, Teacher Wang." Guo Tailai reminded Professor Wang that ultra-high-precision machining parts, if taken by hand, temperature changes will also affect the accuracy measurement.

Professor Wang used two hands and carefully took out the finished metal basketball frame. The CCTV photojournalist recorded this scene in a clear and clear way. Today, the leaders of the Ministry of Information Industry attended the event, and it was of great significance. CCTV also sent reporters to record the whole process. Next to

A dust-free high-precision inspection room on the side is equipped with a series of inspection tools. Careful measurements of various roundness, length, and diameter records that even CCTV photojournalists can only record the measurement process outside through a window.

"The overall processing error is less than 0.2 microns." The two students who operated the laser than the long instrument were the masters. When the result was announced, everyone outside cheered.

With a processing error of less than 0.2 microns, this is already a cutting-edge precision machining center at the international level. The first time you tried to get the car, you got such a result. Why not be excited?

Including Professor Wang, several academicians and professors involved in the study all have a feeling of tears. Huaxia also has an ultra-high-precision five-axis CNC machining center independently designed and produced by itself. Even the leaders of the Ministry of Information Industry are a bit of excitement. From now on, they will no longer have to look at other people's faces.

"However, there is a strange phenomenon." Just when everyone was excited, one of the master students responsible for the measurement forced his own excitement, and his face showed a strange expression, and said to everyone.

Strange phenomenon? Is there a problem with accuracy and instability? Everyone in the heart was screaming, and then I saw the expression of the master student, and I was shocked. "

Not a bad thing. "Master students see everyone's face, and immediately know that everyone misunderstood, and quickly explained: "All the dimensions we measured are accurate 0.2 micron readings. However, the measurement accuracy of this laser is only so high. So we doubt..."

"What do you suspect?" A leader of the Ministry of Information Industry asked anxiously, not a bad thing, but not so good! The heart can't stand it! "

In this case, there is a possibility. Professor Wang took over the words and looked at Guo Tailai, who couldn’t see the distance with a kind of verification. Until he saw Guo Tailai’s nod, this was a loose heart, and the smile on his face could no longer be concealed: “In fact, the processing precision ratio This is even higher, but at the moment our measurement tools are not able to measure more accurately. The school has no more accurate measuring instruments for the time being. ""

What equipment is missing, make a report, I will approve it immediately! "The mood of the leader is like a roller coaster. At this moment, it has risen to the peak again. Then there is a sudden laugh that can't be suppressed.

"Ha ha ha ha ha ha..."
