KTC-2000 is a large CNC grinding machine, large, and fully enclosed horizontal five-axis grinding machine.

The machine tool can not only process compressor blades and ultra-high temperature blades of aero engines, but also large fan blades in front of the engine, not to mention the blades of steam turbines. Originally, Ling Shizhe originally planned to bring the small exhibition string ratio sweep fan to the exhibition, but unfortunately, the processing technology of the small exhibition string ratio sweep fan was not mature, so he had to give up waiting for the next time.

James. Smith. MacDonald circled around KTC-2000 and said to Ling Shizhe: "Ling, can you start the machine tool?" ”

"Yes." Ling Shizhe nodded, because the exhibition has not yet started, so KTC-2000 did not start to do grinding demonstration, but James. Smith. MacDonald has this need, and Ling Shizhe will naturally be among them.

Ling Shizhe waved his hand, called Christopher, who was standing not far away and had been observing the situation here, pointed to the machine tool and said, "Smith take a look at the actual processing capacity of the machine tool. ”

"Okay boss, I see." Christopher replied. And then to James. Smith. MacDonald said, "Mr. James, do you have a sample of the processing?" ”

Smith is James. Smith. MacDonald's middle name, the Chinese name of Westerners is not something that anyone can call, Ling Shizhe and James. Smith. MacDonald has a good personal relationship and can call him by his first name, but Christopher can't and can only call him by his first name or last name.

"Okay." James. Smith. MacDonald took out a drawing from his assistant's hand, and because the drawing was too large, Ling Shizhe personally dragged over a table. Smith. MacDonald spread the drawings out on the table and said, "Can it be machined?" ”

Shown here is a faceted alien form. I don't know what it's for, just when Ling Shizhe was puzzled, a white engineer from Ambrera whispered to him: "Boss." This is one of the parts of a structural component on the new type of wing girder, which is an indispensable spare part of the wing. The best way to do this is by grinding. Before the birth of the grinding machining center, the processing of this part could only be done by hand, which was time-consuming and laborious, and the scrap rate was extremely high. An experienced grinder who wants to process such a part will not be able to complete it in less than a month, and he will face the risk of product scrap at any time. ”

Listening to him, Ling Shizhe knew that Christopher was facing a challenge this time. If you want to win McDonnell Douglas's order, you have to gnaw on this hard bone, otherwise KTC-2000 can only be a toy for your own play. For this reason, Ling Shizhe couldn't help but worry about Christopher, wondering if they could complete this challenge.

Looking at Christopher's tightly knit brow, James. Smith. The corners of MacDonald's mouth curled, and with a distinctly wicked smile, he said, "Mr. Engineer, can you do it?" ”

Christopher ignored his wicked smile and replied with a very serious expression: "Yes, give me 5 hours." ”

"Mr. Engineer, do you know what you mean? Don't brag. "James. Smith. MacDonald is well aware of how difficult it is to machine parts on a drawing paper. It is one of the most critical parts on the wing, which was said by aircraft designers back in the mid-50s. Wings made of these parts will not only be significantly lighter, more powerful, with minimal wing load, the aircraft will also gain maximum lift during flight (30% higher than the traditional structure of the wing), fuel consumption will be reduced by 20%, and the maintenance and maintenance costs of the wing will be reduced by 50%, but aviation materials and machining technology have always been not up to par. Therefore, most aircraft designers, when designing the structure of aircraft wings. They can avoid the use of such parts as much as possible, or simply redesign a wing structure. In this way, the cost of aircraft manufacturing is saved.

If Christopher can really solve this problem, then it is not an exaggeration to say that the fabrication of the wing will lead to a revolution. Smith. MacDonald began to look forward to it.

An hour later, Christopher and his team of engineers completed the machining plan of the part, then took out a piece of titanium alloy from the small warehouse in the display area, opened the safety door of the machine, put the material in and fixed it, and replaced several tools at the same time...... Adding a new program, when everything was ready, Christopher started the KTC-2000, and an exciting beep of the CNC machining center was heard, and the machining began!

The test began, with the start of formal processing, the milky white coolant stirred up bursts of water, a large amount of coolant from the coolant nozzle of the machine tool sprayed on the parts, the coolant can fully cool the parts, prevent the parts from heating up during the machining process. The spindle of the machine tool moves quickly and is positioned, and the first CNC knife begins to rotate rapidly, tangentially towards the part, and a large number of metal chips are cut down.

James. Smith. MacDonald stepped forward and peered through the closed security door glass, where water was spraying with milky white coolant at a certain pressure on the part being processed. After looking at it for a while, James. Smith. MacDonald said to Christopher: "Mr. Engineer, will there be a problem with this high speed?" ”

"My name is Christopher." Christopher corrects James. Smith. "I'm confident in KTC-2000 that in five hours, the results will be out," MacDonald said. ”

"I can wait five hours, I'll keep my eyes on it and wait for the results to come out." After all, James. Smith. MacDonald took a chair and sat next to Ling Shizhe.

Time passed minute by minute, the machine began to automatically change the tool, and continued to process at high speed after replacing a new tool, Christopher looked at the processing situation, and then looked at the metal chips discharged from the chip chute of the machine tool, and nodded with satisfaction.

The movement here alarmed the people in the exhibition area of other companies around, and the person in charge of some exhibition area sent his little brother to inquire about the situation here, and when he knew that Ambrera was showing a new machine tool to McDonnell Douglas, the person in charge of the company's exhibition area could not sit still and rushed to Ambrera company's exhibition area. At first, there were more and more people......

The situation here also alarmed the official organizing committee of the Frankfurt Air Show, which sent an official to investigate the situation. "Sir, no onlookers are allowed here."

"Fuck off, go aside." James. Smith. MacDonald waved his hand in annoyance. Tell the officer to fuck off.

The officer saw James. Smith. The great god MacDonald sat here, quickly closed his mouth, and then saw James . Smith. Next to MacDonald sat a young man under the age of 30, with a somewhat familiar face, and then remembered who this young man was, so he left the exhibition area of Ambrera in a frightened manner, and hurriedly asked the top official of the organizing committee, Wolfgang. Feng. Miller reported that it went.

The officer's actions. I reminded the heads of the exhibition areas of other companies around me, and like a chain reaction, they returned to their booths one after another and called their department heads.

"What, before the show even started, Ambrera started performing, who are they performing for? James. Smith. MacDonald, show him, what's the show...... What a five-axis machine! You're not mistaken, right? ”

"Yes, sir, I inquired clearly. At this exhibition, Ambrera company presented their newly developed machine tool, called KTC-2000 five-axis horizontal grinding machining center. Now it's working for James. Smith. Mr. MacDonald does a show. The chairman of Ambrera & Co., Jester. Ling is also there. ”

The news spread like the wind throughout the exhibition, and all the companies participating in the Frankfurt Air Show knew that Ambrera had developed a five-axis CNC machine. This is a five-axis CNC machine! At present, the five-axis machine tools of major machine tool companies are still on the drawings, but I didn't expect Ambrera to get it out in advance.

Then people asked, since Ambrera has made a five-axis CNC machine tool, why not go to the International Machine Tool Show, but show it at the Frankfurt International Air Show? Soon the executives of major companies reacted that this machine tool must be related to the aviation industry, so the top leaders of many aviation manufacturing companies could not sit still and flew to Frankfurt, West Germany. Clark, Airbus President von Clarke. Dai Bolong, President of Pratt & Whitney Company Qiao. Varney.

Five hours. It's getting completely dark, James. Smith. MacDonald and Ling Shizhe were already hungry. Ling Shizhe instructed the staff to buy some hamburgers and hot dogs from a nearby fast-food restaurant. "Come to Smith, let's have something to eat first."

"I'll eat later, I'll invite you." James. Smith. MacDonald refused, "How much time is left?" ”

Christopher walked to the front of the machine and saw through the glass safety door that the machining center was still processing parts according to the CNC program; At this point, the parts on the machine are basically formed, and "there are still 30 minutes left to complete the processing." ”

Ling Shizhe vs. James. Smith. MacDonald said, "We'll wait. ”

James. Smith. MacDonald nodded.

Time passed minute by minute, the processing gradually approached the end, thirty minutes passed quickly, the machine tool spindle began to retract, only to see the machine tool spindle quickly lifted, rapidly rotated away from the processed parts, the speed slowly decreased and soon stopped.

Soon, the safety door of the machine tool opened, and the parts that had been processed were lying quietly on the workbench of the machine tool, and the shiny parts were shining with metallic luster and looked very beautiful.

Christopher couldn't wait to blow the metal shavings near the parts clean with a high-pressure air gun, and then the soft brush cleaned the parts clean, looking at this beautiful part, Christopher's hands trembled slightly.

"How's it going?" Ling Shizhe couldn't wait to ask.

Christopher replied, "Boss, everything is going well, the parts have been machined and are being disassembled on the machine table." ”

Hearing that everything was going well, Ling Shizhe's high heart was invisibly put down, and he walked to the front of the CNC machine tool in a few steps, and saw the parts that had been processed on the machine tool workbench at a glance, and suddenly burst into a burst of joy and a happy mood.

"Take the parts apart and I'll measure them myself." James. Smith. MacDonald said calmly.

At this time, there were already many people around the machine tool, and most of them were from his company. Christopher expertly disassembled the part and gently placed it on the work table next to the machine.

After the parts are processed, they are very beautiful, with the unique metallic luster of titanium alloy, shiny, and immediately attracted everyone's attention.

It's beautiful!

This appearance alone is absolutely superb, James. Smith. MacDonald picked up the part, looked at it and looked at it, couldn't help but exclaim, "It's unbelievable." Then he put the part down, "Bring the tool, I'm going to measure it, and see how the part is dimensioned." ”

From just now, the appearance of this part is absolutely first-class, if the size is fully qualified, it is a qualified product, this part has been a roadblock in the aviation processing industry before, if the processing is successful, it is to gnaw off a hard bone.

Ling Shizhe's heart was also full of expectations, and he prayed in his heart that all sizes would be qualified at one time.

Soon the measuring tools arrived, James. Smith. MacDonald began to measure one size at a time against the drawings, and as the measurements followed, James. Smith. MacDonald let out a look of exclamation.

Medium!

Medium!

Medium!

……

Most of them are in the middle of the range.

The people around were also excited and shocked, watching the dimensions being measured one by one and recorded on the process flow card one by one. Then there is the three-coordinate measurement and strength test, and most of the measurement results are also moderately poor, but in the strength test, people find differences.

They found that the strength of the part was excessive, and a lot of the steel was still hard.

"Oh my God, how can it be so hard?" Many people at the scene invariably raised questions, some amazed and some questioned.

James. Smith. MacDonald was also confused, and said to Ling Shizhe: "Ling, you explain to me what is going on." ”

"Don't worry Smith," Ling Shizhe smiled, "Take a good look at the part in front of you, and take a closer look at what material it's made of." ”

"Oh, it's titanium......" James. Smith. MacDonald said directly, and then he was not calm, "Wait, isn't titanium alloy difficult to machine?" How did you see how easy this machine is to process just now? ”

"The difficulty in processing titanium alloy is caused by the immaturity of titanium alloy smelting technology." Ling Shizhe smiled: "Smith, our Ambrera company has developed a new type of titanium alloy material, this titanium alloy not only has good machinability, but also its structural strength is stronger than many steels on the market. ”

Rumble! The people around are not calm, looking at Ambrella's new processing machine tool, I didn't expect a new type of titanium alloy material to burst out in the end, it seems that this time it is simply worth the trip.

Looking at the envious eyes around him, Ling Shizhe said proudly: "Smith, in addition to the new titanium alloy material and the KTC-2000 five-axis horizontal grinding machining center, we have other new things, come with me, I believe you will be surprised." (To be continued)
