Yes, it's really beautiful.

I saw that on the working plate in the center of the machine tool, a rough part of the face gear with a diameter of about 400mm was fixed, and the worker pressed the start button as the worker entered the program on the PC control terminal next to it.

A probe-like thing pops out quickly, touches back and forth on the serration of the face gear a few times, and then retracts, and then the PC control terminal displays the basic parameters of the face gear, and quickly calculates the optimal contact angle and distance between the grinding wheel and the face gear.

After the worker clicks OK, the worm grinding wheel with concave and convex water chestnut in the machine tool will quickly paste the face gear that has adjusted the processing angle.

The next moment, the grinding head and the worktable rotate at the same time, accompanied by a waterfall-like coolant pouring down, the uneven edges and corners on the grinding head of the worm grinding wheel and the serrations on the face gear are well meshed, and the gears are repeatedly ground with the high-speed operation of the equipment.

However, just when everyone thought that this machine tool was like this, a magical scene appeared, between which the worm grinding wheel grinding head suddenly stopped working and detached from the processing interface, and at the same time another rotating grinding head was moved out of the machine with a cake-shaped grinding wheel on it.

At this time, the angle of the worktable is changed again, so that the round cake-shaped grinding wheel and the sawtooth of the gear are meshed, and when the grinding wheel rotates, the worktable does not rotate with it, but rhythmically makes a curve-shaped up and down rhythm with the gear, and begins a more detailed fine grinding.

At the same time, two high-speed tools around the removed worm grinding wheel begin to modify the worm grinding wheel to be closer to the fit of the surface gear after fine grinding.

After a period of fine grinding, the worm grinding wheel is also readjusted, and the two grinding heads are switched again.

After several times of repeated this, the originally dull face gear has already been shiny as new after several rounds of precise polishing, and the alluring metallic luster, which sets off the sawtooth like a work of art, makes people have a sense of déjà vu that they can't put it down.

At this time, a probe-like thing pops out again in the machine tool, close to the face gear that has just been processed, this time the probe does not move, but the face gear is undulating with the workbench, sometimes moving, sometimes rotating, sometimes oblique, so that after about ten minutes, the probe is retracted, and the whole processing process is officially over.

The leaders of the troops, including Meng Qingguo, were full of excitement and enthusiasm.

There is no way, this kind of industrial beauty with a sense of power, only when you are immersed in the scene can you feel the unique charm of the fusion of aesthetics and mechanics, especially the moment when the coolant pours down, the indescribable sense of pleasure is really fascinating.

Of course, what is more important is that the processing process of lucky flowing water is really comfortable, even if the person with severe obsessive-compulsive disorder can't find fault with it.

"Nice, nice......"

Seeing such a perfect process, the head of the headquarters nodded in admiration, and immediately turned his head to prepare a few words of encouragement to Zhuang Jianye, but when his eyes swept to Zhuang Jianye, he suddenly found that a workshop staff handed over a few pieces of paper, and the words of encouragement to his mouth were immediately replaced by a curious inquiry: "Xiaozhuang, what is in your hand?"

"Oh, it's the inspection report of the face gear that was just machined. ”

Zhuang Jianye's voice was not loud, but when he heard the ears of the leaders, he unintentionally exploded a thunderbolt, you must know that the surface gear parts that have just been processed are still lying on the workbench, why did the test report come out?

Could it be that the invisible man came to do the test?

How can it be!

"Old Meng, take a look. ”

The head of the headquarters took the test report handed over by Zhuang Jianye, glanced at it twice and handed it to Meng Qingguo, who was full of disbelief, Meng Qingguo took it in his hand, frowned and looked at it several times, and looked at the gear on the workbench several times with a hellish look.

It was repeated over and over again several times until the head of the headquarters became impatient and urged: "Old Meng, you are talking, whether it is a test report or not." ”

"Yes...... It's a test report, not only ......" Speaking of this, Meng Qingguo swallowed a mouthful of saliva, looked at the gear on the workbench again, and said with some difficulty: "And the data is very detailed, and the professional laboratory of the Advanced Research Institute is only at this level." ”

As soon as these words came out, the leaders of the surrounding troops gasped together, no one came to test it, and the accuracy of the measurement was comparable to that of the professional laboratories of advanced research institutions, how did Tengfei Group do it.

"Comrade Zhuang Jianye, I didn't see that you have a measuring room here, but your report ......"

The leaders of various units have doubts in their hearts, but they can bear it, Meng Qingguo doesn't have this qi cultivation kung fu, a bearing, a gear, those are the two most used components of helicopters.

Now Tengfei Group's Xiangzhou factory has mastered the production process of advanced gears, which is by no means good news for the porcelain capital and Binjiang, so Meng Qingguo has no care about picking what quantity is not mass-produced, and whether it is a cost, so he will figure out the current matter first.

So Meng Qingguo couldn't wait to ask the questions of everyone present, but before he finished speaking, he was interrupted by Zhuang Jianye with a smile: "Isn't this an obvious thing." ”

As he spoke, he pointed to the NB-404 CNC worm grinding wheel gear grinding machine in front of him: "Just let the machine detect it by itself." ”

"Let the machine detect it itself?"

Meng Qingguo was a little stunned when he heard this, but Zhuang Jianye pointed to the two retracted probes in the machine tool and said: "These two probes, the one on the left is the positioning probe, which is used for position measurement before the workpiece is processed, so as to determine the processing angle, the distance of fine grinding and the strength of grinding.

The one on the right is the measurement probe, with the surrounding laser locator, you can make accurate measurements of the accuracy of the workpiece, if it meets the standard, it will be sent back to the calculation and terminal through the communication line, and the test report will be issued, and the file will be archived for later use......

Taking this as an opportunity, Zhuang Jianye began to make a comprehensive introduction to the NB-404 CNC worm grinding wheel gear grinding machine, if the United States gear grinding equipment is unique in the world, a single one, then NB-404 CNC worm grinding wheel gear grinding machine although not as good as the products of American friends, but to say that the gap is not as big as imagined.

It is nothing more than that the American friend is a worm grinding wheel, and the tooth head of the round cake grinding wheel is all flat; NB-404 CNC worm grinding wheel grinding machine does not have this free and easy energy, and needs to be divided into two to achieve.

In addition, the NB-404 CNC worm grinding wheel gear grinding machine is not much worse than the products of friends in the United States in terms of accuracy, efficiency and even operating costs.

If not, how dare Tengfei Group apply face gear coaxial torsion technology on the straight-12Pro exported to Pakistan?

In the final analysis, Tengfei Group has the confidence to achieve real industrial mass production of this technology.

After listening to Zhuang Jianye's introduction, the leaders of the troops were all excited, although Meng Qingguo was not excited, but he was also happy for the achievements of the Xiangzhou factory, but he quickly thought of another question, so he frowned and asked: "Comrade Zhuang Jianye, you should invest a lot in the NB-404 CNC worm grinding wheel gear grinding machine you developed, right? When is it expected to recover the cost?"

Zhuang Jianye's smile was even brighter: "The cost has been recovered, and now the production is all pure profit!"
