Smith was looking at the blade seriously, even holding a magnifying glass, very attentive, Giovanni and Martinez walked over, Smith didn't notice until he heard Martinez's voice.

Reluctantly putting down the blade in his hand, Smith said: "Mr. Giovanni, Mr. Martinez, are you asking about the processing quality of this blade?" ”

Martinez said: "Mr. Smith, I asked about the processing quality of this batch of parts processed by Tianfeng Technology Company. ”

"Oh, you're asking about this batch of parts." Smith was stunned, then spread his hands and said with a smile: "I only looked at two parts in this batch, and after I found these leaves, I was attracted by these leaves." ”

Martinez was most concerned about the machining quality of these parts, not these blades, and at this time, Martinez did not realize the extraordinary features of these blades.

Martinez said: "Mr. Smith, you are our senior engineer, according to your professional level, what is the quality of the two parts you checked?" ”

Smith said: "As far as the two parts I have just looked at are concerned, the machining quality is very good, first-class and fully meets our quality requirements. ”

Excellent! Superb at the top!

Martinez was overjoyed and couldn't help but glance at Giovanni, who asked, "Mr. Smith, is the processing quality really first-class?" ”

"Absolutely first-class, I vouch for my professionalism, there will be nothing wrong with that." Smith affirmed.

Hearing this, Giovanni personally leaned down, picked up a part, unpacked it, and took out the part, the moment the part was unpacked and unpackaged, Giovanni's eyes lit up, when he was young, Giovanni was also an engineer, and he worked step by step from a technical job in the early days.

"The parts are beautifully machined." Giovanni sighed with emotion in his heart, and at the same time, Giovanni also knew that the report he had just received must be wrong, and the subordinate who reported to him must have done oolong.

However, at this time, Giovanni did not have the slightest intention to pursue the subordinate who came with a big oolong, and at this time, Giovanni was completely immersed in joy.

Martinez is not like this, seeing such a beautifully machined part, his heart is also a burst of joy, a burst of excitement.

"It's so beautiful!"

Martinez even waved his fist excitedly, the little depression caused by Giovanni's criticism just now had long disappeared, and his heart was full of joy and joy, such a high-quality quality, he could completely raise his eyebrows.

After looking at it for a long time, Giovanni put down the part in his hand and said apologetically: "Mr. Martinez, I almost blamed you just now, I apologize to you." ”

Martinez was happy and happy, where would he care about this, and hurriedly said: "BOSS, it doesn't matter, compared to this high-quality, shocking part, a little misunderstanding is nothing." ”

Giovanni glanced at Martinez, nodded, and then picked up another part with great interest and looked at several parts in a row, and Martinez was the same, very happy to see several parts in person.

These parts, without exception, are all very beautifully processed, and each part also has a certificate, which has the bright red seal of the quality department of Tianfeng Technology Company. In addition, each part has a record of the measured value of the dimensions.

On this record sheet, each size is recorded neatly and clearly, and each size is all qualified, and none of them are out of tolerance.

Tianfeng Technology has also done a very good job of these details, which made Giovanni and Martinez very satisfied, and the two looked at each other and nodded to each other.

And Smith seemed to be very fascinated by these leaves, as if he had met two rare treasures, and he couldn't put them down, and now, holding a leaf and a magnifying glass, he looked at it seriously, and even looked at it in amazement.

After Giovanni and Martinez looked at these parts of Tianfeng Technology, they inadvertently saw Smith's expression, and the two looked at each other again, and the two looked puzzled.

Giovanni even thought in his heart, what kind of treasure is this leaf, it is so focused, so fascinated, and looking at Smith's expression, there is even a little surprise, a little excitement, this, what is going on?

Martinez was also puzzled for a while, couldn't help but put down the parts in his hand, and asked puzzledly: "Mr. Smith, what is the name of this blade?" You are so interested. ”

Smith said: "This blade is not simple, very not simple, representing a new process of blade processing, this new process, we have been researching, but far from success, did not think, Tianfeng Technology Company mastered this new technology, and also processed samples to send us over." ”

The layman looks at the bustle, and the insider looks at the doorway.

As a senior engineer of Pratt & Whitney, of course, Smith saw the extraordinaryness of these blades, and it was precisely because he saw the extraordinary, so Smith was so focused, and the more he looked, the more surprised and excited he was.

Hearing this, Giovanni and Martinez glanced at each other, both of them were a little unconvinced, how could Tianfeng Technology Company master such a new process, you know, the new process of blade processing, that is very remarkable.

Although Martinez spoke highly of Tianfeng Technology, he didn't believe that Tianfeng Technology had such technical strength, so he couldn't help but shake his head in disbelief.

Seeing that the two didn't believe it, Smith was a little anxious, and immediately said, "You take this magnifying glass and take a closer look at the processing lines on the blade." ”

The two took a magnifying glass and took a serious look at it one after another, Giovanni was born in technology, and he also saw the extraordinary, Martinez has been mixed in the aviation industry for so many years, and he also knows a little bit, and he also sees the extraordinaryness of the blade.

Giovanni said: "The blade is not milled, nor is it like the traces of manual grinding, but like grinding, but can the blade be grinded?" ”

Martinez also said: "It's really strange, I don't understand a little, the various blade shapes of aero engines are generally very complex, how can they be grinded?" ”

Smith nodded, "I'm 100 percent sure that a few blades are made of a grinding process, and it's a very advanced grinding process. ”

"It's really a grinding process." Giovanni was a little surprised, and even knew the advantages of the grinding process, that is, the machining accuracy is high, the surface roughness of the parts is excellent, and some high-quality, high-demand places, many of which are grinding.

For example, the shaft parts of aero engines, the journal part of the bearing is generally very high, not only the outer circle tolerance is very small, and the cylindricity of the journal outer circle is generally only a few thousandths, and there are strict journal runout requirements.

Such a demanding part is generally grinding, and only grinding can achieve such precision requirements.

If you want to turn, mill, planing, grinding these kinds of machining methods, in terms of machining accuracy in an order, undoubtedly, grinding processing to rank first, in high-precision machining, grinding processing has irreplaceable advantages.

Of course, grinding also has its shortcomings, and its processing efficiency is often very low while high-precision machining.

Giovanni is a technical background, well aware of the advantages and disadvantages of grinding, so, Giovanni said: "The grinding of blades, if it can really be realized, the machining accuracy must be top-notch, but the processing efficiency is too low, such a blade processing, I am afraid that it will take a lot of time." ”

Who knows, Smith shook his head again and again, "No, no, Mr. Giovanni, I think you are mistaken, there is a new process of five-axis linkage high-speed and high-precision grinding, and the processing speed of grinding blades is very fast, which is much higher than the traditional five-axis linkage CNC milling processing efficiency." ”

"Is there such a process?"

Smith said confidently: "Of course, I believe that Tianfeng Technology has thoroughly mastered this new process, which can be seen from these blades." ”

Listening to Smith, Giovanni and Martinez also realized the extraordinary features of this new process, especially for the processing of various high-precision blades of aero engines.

Martinez said: "Mr. Smith, such a blade processing technology, we have not mastered Pratt & Whitney? ”

Smith shook his head regretfully and said: "We are far from mastering such a new technology, the five-axis linkage high-speed and high-precision grinding process on the blade surface is a cutting-edge technology, we have just begun to study, without a few years of effort, it is absolutely impossible to master such a technology." ”

"That's right."

Giovanni and Martinez glanced at each other, and their hearts were solemn, such a technique, he actually didn't master it, and the problem was a bit strict.

Giovanni said, "Mr. Smith, you should study these leaves carefully, and then write a detailed report to me, and I will submit it to the board of directors for discussion." ”

Mr. Smith naturally hoped that Pratt & Whitney would master this new technology, so he nodded happily and vigorously, "Mr. Giovanni, I will definitely write this report with my heart." ”

Martinez said: "BOSS, are you going to propose it in the board of directors to introduce this technology from Tianfeng Technology?" ”

Giovanni nodded: "That's what I mean, Mr. Martinez, you see that Tianfeng Technology has given us a sample of the blade, and their intention to sell this technology is very obvious." ”

Martinez felt that something was wrong, but he was not sure, so he just nodded and did not say anything.

In fact, Giovanni really misunderstood, Li Tianfeng sent these blades, naturally not to sell the technology in his hands, but to get a large amount of blade processing business from Pratt & Whitney.

And Giovanni didn't think so, Giovanni planned to spend a little money to buy this technology and turn it into a new technology from Pratt & Whitney.
