"Come with me!"

The huge sea beckoned and took the lead to the corner of the factory. Pen & Fun & Pavilion www.biquge.info

Grinding area, in front of two grinding platforms.

Hand grinding is generally carried out on the grinding plate, which is square, the size is 300×300mm, the material is forged from cast iron, and the accuracy level is not less than △9, that is, Ra<0.2μm.

Plates are made in groups of three.

"There's not much time, let's grind the cylinder more simply than a little." At the signal of the huge sea, a man brought up two bead-shaped workpieces.

"No problem!"

Tian Ze nodded quietly.

In fact, Tian Ze had already scolded in his heart, don't look at the bead workpiece is only 20cm high, and the diameter is only 10cm, and the simple structure can't be simpler. But if you think that the cylinder is easy to grind, then it is very wrong, the upper and lower bottom surfaces are really not difficult, and the difficulty is difficult on the curved surface.

Because of this kind of arc grinding, it often adopts the form of movement with manual and motorized movements.

When grinding, the workpiece is clamped on the head of the bed by means of circlip and center hole jacking at both ends, and the rotary motion is driven by the spindle of the machine tool, and the axial reciprocating and forward and backward swing movement is carried out by manual operation.

Now it's completely manual, and this difficulty is not ordinary!

"Let's get started! The abrasives are right next to them. ”

A hint of battle flashed in the eyes of the huge sea, and he pointed to the cabinet next to the grinding platform and said. Not really! Various types of abrasives are placed in the cabinet one by one.

"Good!"

A glint flashed in Tianze's eyes.

moved, Dang Hai took the lead in walking to the cabinet, opened the cabinet and took out a bottle of abrasive, and evenly applied the abrasive to the bottom of one side of the cylinder. Then I saw Da Da Hai holding the cylinder and gently pressing the bottom surface coated with abrasive against the plate......

And what about Tianze?

Everyone turned their heads and looked, good guy, are you still in a daze?

Stunned, he looked at the cylindrical workpiece on the platform.

Is this to give up?

A trace of disappointment flashed in everyone's eyes, and many people shook their heads. Among them, Zhuo Yan was the most disappointed, not only because Tianze was found by him, but also disappointed by Peng Ai's party, thinking that Peng Ai's party had seen the wrong person and mistakenly regarded the stubborn stone as Puyu.

The real Puyu will not be timid because of the name of the huge sea, and he doesn't even have the courage to draw his sword, what kind of life can such a person have?

Tianze is really as everyone guessed.

Timid?

……

Naturally, not.

Tianze is not in a daze, but in starting the PS system.

"System, loading a cylindrical workpiece on a platform."

"Drop! Start onboarding. In a burst of electronic sound, there was an additional hologram in the blue stereoscopic space of the PS system, which was the hologram of the cylindrical workpiece on the platform.

"Turn on scanning."

Tian Ze then ordered.

Almost immediately, the PS system finished scanning, and the electronic sound sounded again, "Drop!" The scan was completed with a mechanical workpiece with a surface accuracy of Ra25μm and a rough finish. ”

"Immediately turn on the system removal function, the mode is manual mode, and the accuracy requires Ra0.08μm." Tian Ze continued to order.

Generally, after grinding, the dimensional accuracy of the workpiece can reach IT5-IT2, and the surface accuracy can reach below Ra0.2. Considering that Da Da Hai is not an ordinary person, and his level is not comparable to that of ordinary technicians at all, Tian Ze naturally has to raise his requirements, otherwise there is no possibility of winning at all.

"Drop! Manual mode is on. ”

In a burst of electronic sounds, Tianze finally moved.

Walked to the cabinet.

"Great!" Zhuo Yan almost couldn't help cheering, happy that he didn't look at the wrong person, happy for Tianze's courage, and even more happy that Peng Ai's trust in the party was not in vain.

The others nodded their heads as well.

Whether it is a win or a loss, Tianze at least dares to fight.

Not a coward.

Under everyone's gaze, Tianze took out the abrasive numbered W20, which is a white jade powder, W20 indicates that the particle diameter is between 20~28μm. It is generally used for rough grinding, grinding to remove pre-machined cut marks, and achieve the machining accuracy required for rough grinding.

Apply abrasive, grind.

Almost in one go.

Twenty minutes later, Tianze completed the preliminary grinding of the upper and lower bottom surfaces of the cylinder.

Then, Tianze took out the abrasive numbered W3.5.

Flat finishing is performed again to further improve the surface finish and geometry accuracy in preparation for the final fine grinding.

Ten minutes later, Tianze completed the grinding of the upper and lower bottom surfaces of the cylinder.

Then, Tianze took out the abrasive numbered WL again.

Begin the final finishing of the upper and lower undersides.

Tian Ze didn't notice that Da Da Hai had already put down the cylindrical workpiece in his hand, and gently came behind him, looking at the movements in his hand with an obsessive expression. It's so smooth, it's so perfect, it's as precise as if it's being controlled by a computer, it's not like a human being can do it at all!

Five minutes later, Tianze finished grinding.

At this point, the grinding of the upper and lower bottom surfaces of the cylindrical workpiece is completed.

Tian Ze was about to continue grinding the arc surface of the cylinder when the huge sea suddenly rushed up and snatched the cylinder body from his hand.

"Old Pang, what do you mean by that?" The grinding was interrupted, and Tian Ze couldn't help but ask with a dark face.

Da Dahai didn't answer, as if he hadn't heard Tianze's questioning. Instead, the residual abrasive on the upper and lower surfaces of the cylinder is quickly washed away with a cleaning solution.

As the residual abrasive is washed away.

The upper and lower bottom surfaces of the cylindrical workpiece, like a dusty orb, finally reveal its own brilliance, which can be used to illuminate people, and there is no trace of it anymore.

As a master fitter, Panghai sees more.

Even if it has not been tested, Panghai can be sure that the roughness accuracy Ra of the upper and lower bottom surfaces of the cylindrical workpiece is absolutely less than 0.09 μm and more than 0.07 μm.

So, Ra is around 0.08 μm.

"The old man is convinced."

Da Da Hai looked at the cylinder in his hand and whispered in his mouth.

"Don't continue to compare?"

Tian Ze was stunned for a moment and did not react.

Only then did the grinding of the upper and lower bottom surfaces of the cylindrical workpiece be completed, and the most difficult cylindrical arc surface had not yet begun to grind, so why did the huge sea admit defeat? The contrast between this and the strong self-confidence that Dang Hai just showed is a little too great, right?

"If you don't accept it, you can't do it! The best level of the old man is only 0.09μm, is there any need to compare it? Huge Hai sighed, a little lonely, and a little excited.

I am lonely because my skills are not as good as others.

He is the chief technician of the country and one of the top 100 technicians in the country! Now he actually lost to an unknown senior technician, what is even more surprising is that this person is still so young, he must be less than half his age, right? How can the huge sea not be lonely?

I was also excited to see such a superb skill with my own eyes.

This is purely for the fitter industry to be happy to have such an excellent talent.

"Pang Lao, admit it."

Seeing that the huge sea was so bright, Tian Ze couldn't help but feel a sense of admiration in his heart, this is the real master! Not only is the craftsmanship superb, but also the morality!

"Well, the young man didn't disappoint us." The old man of the major general said appreciatively.

"Xiaotian, it's good."

Zhuo Yan couldn't help but praise.

"Uncle Zhuo, can you say it now, what is the purpose of calling me over?" Tian Ze couldn't help but ask at Zhuo Yan.

This is another helicopter, another competition, Tianze still doesn't know what parts to process, this heart is naturally a little anxious.

Zhuo Yan didn't reply directly, but looked at the old man of the major general, and the old man thought for a while and said, "I think so!" Lad, you go to the reception area for one night, and we'll talk about that tomorrow. ”

"Xiaotian, you can stay for one night first! It's almost ten o'clock now. Seeing what Tianze wanted to say, Zhuo Yan preemptively reminded him.

Ten o'clock?

Tian Ze was shocked, the mobile phone was confiscated, and Tian Ze really didn't realize that it was ten o'clock in the evening. After Zhuo Yan's reminder, Tianze realized that he was indeed a little sleepy, so he didn't insist anymore.

It's so late after all.

After saying goodbye to Zhuo Yan and the others, under the leadership of a soldier, Tian Ze returned to the suite just now. After taking a hot bath and eating the dinner brought by the soldiers, Tianze got into the bed.
