When NC apprentices have a task system

Chapter 19 Prickly Race Steel (POM)

"Okay, just to check what Xiao Xu has learned just now?"

Deng Shan on the side agreed.

"Ding! Trigger the task of the special NPC Xu Hui: Clamp and fix Sai Gang, and complete the prelude trilogy: watch, score, and knife setting! It is required to show perfect technical level and shock Xu Hui. Reward for completing the task: money +400! Experience +400! Machine operation experience +400! A copy of Xu Hui’s CNC machining center experience! There is a chance to steal Xu Hui’s skills once!”

"Ding! Are you? Yes? No?"

"Ding! The task of triggering the dungeon NPC Deng Shan: Demonstrate the trilogy of clamping and processing prelude. Task completion reward: money + 400! Experience + 400! Operating experience + 400! Experience of Deng Shan's CNC machining center! There is a certain Chance to drop special rewards! Reminder: The stronger the effect displayed, the greater the probability of special rewards falling!"

"Ding! Do you accept? Yes? No?"

Xu Yang looked at Deng Shan and Xu Hui, who were collaborating together, and felt happy:
"Hey! How can Zhengchou verify the effect of the title [handy]?"

Now it's all right, Deng and Xu will come to your door...haha!
This is really, sleepy send pillows, whatever you think!
What's more, the tasks of the two are repeated, which is a double reward!

A beautiful event that can't be seen once in 100 years!

Seeing this scene, Xu Yang pretended to be embarrassed and said:
"I come?"

"That's right, Xiao Xu has to believe in himself."

"That's right, don't feel burdened, we are afraid of the ball!"

Deng and Xu looked at each other with treacherous smiles.

I saw Xu Hui thinking like this in his heart:

"Haha! Xiao Mian... I told you to take advantage of my clan's seniority just now... You must suppress it."

Hey!

But Deng Shan on the side made up this scene in his mind: under the black wood cliff, Yue Buqun (Xu Hui) fought against Linghu Chong (Xu Yang), staged a master-student killing each other, and he himself was injured and let me walk aside Watching the show in silence.

quack!

……

"Yes!"

"Yes!"

Xu Yang took over the task in one go.

How to clamp Saigang?

Xu Yang decided to ask for help from the system: "System, I need Saigang's popular science knowledge."

"Ding! The Saigang science knowledge you need has been transmitted!"

"acceptance!"

As soon as the words fell, a large amount of information poured into Xu Yang's brain, digested and assimilated...

After a while, Xu Yang had a general understanding of Sai Gang.

Having said that, I have to mention the material Saigang.

Saigang, also known as polyoxymethylene, English name: POM, belongs to the plastic category.

Saigang has a very low coefficient of friction and good stability, especially suitable for making gears, bearings, fixture pressure heads, etc.

However, Saigang has a big flaw, and it is a problem that has caused headaches for countless mold masters.

Transform!

The deformation of Saigang has the following factors:

First, clamping deformation. Unlike 45# steel, Saigang will deform when clamping. After rough machining, the product will return to its original state, so the tolerance cannot be controlled.

Second, thermal deformation, a large amount of heat is generated during processing, and Saigang is sensitive to heat, which can easily lead to deformation.

Third, elastic deformation. Saigang has good toughness. When cutting, the product will undergo elastic deformation. After the tool leaves, the product will recover a certain amount of deformation, resulting in uncontrollable tolerances.

The following steps can be taken to address these factors:
First, standardize the blank material before rough machining, then open the back plate, and process as much as possible to reduce deformation.Therefore, when clamping Saigang, it is best to fix it with AB glue to minimize the deformation caused by clamping.

Second, use a white steel knife instead of an alloy knife to process Saigang, because the white steel knife is very sharp, and the heat generated during the cutting process is relatively small.

Third, when processing, don't cut too much.

"Is that so?"

After knowing the characteristics of Saigang, the traditional clamping and fixing mode of the horse is definitely not feasible.

"How to clamp?"

"Deformation?"

These two factors have been echoing in the mind, causing desire to fall into contemplation.

Seeing this, Deng and Xu couldn't help frowning. They seemed to be expecting Xu Yang's performance.

As Xu Yang's leading master, Xu Hui first put forward his own ideas:

"Old Deng, how do you think Xu Yang has learned?"

"This is a test question. It depends on whether he listened carefully just now?"

Deng Shan shook his head and said.

To be honest, Deng Shan didn't think that Xu Yang could quickly complete the machining prelude trilogy for the first time, because there is still a difference between the CNC machining center and the engraving machine.

To put it bluntly, in the eyes of the master of the CNC machining center, the engraving machine is just a toy.

Got it!

At this time, Xu Yang suddenly had a bright light in his mind, and he thought of a way.

That's right!

The artifact for repairing the test frame - AB glue.

"Mr. Deng, XCMG, shall I start?"

"Ok!"

After finishing speaking, Xu Yang used an air gun to blow off the surface of the machine table, and then put Sai Gang into it.

Gently press it down with a ponytail, and the next step is to play the watch.

"Handy, it's up to you!"

Xu Yang took a deep breath, then attached the dial indicator to the protective cover of the spindle and started dialing.

"what!"

At this moment, Xu Yang saw an infrared ray, a feeling of deja vu, yes, it was the automatic aiming mode when drilling the hole last time.

Xu Yang was overjoyed, he put Sai Gang on the infrared line without hesitation, and then moved the X axis, an incredible scene happened.

"This……?"

Xu Yang was dumbfounded. According to the placement of Saigang according to the infrared rays, the horizontal and vertical deviation of the workpiece is only 20 wires, which is incredible.

This is simply a humanoid dial indicator.

After being shocked, Xu Yang quickly calmed down, and on the surface he was still serious about schooling.

With 20 wires, according to the method of which head hits which side, Xu Yang controlled the horizontal and vertical swings within 1 wire in less than five seconds.

Perfect calibration!

At this moment, two exclamations sounded again and again.

"Enough?"

"1 silk?"

I saw Deng and Xu's eyes widened at this moment, showing the feeling of extreme shock on their expressions.

Originally, the two were not optimistic about Xu Yang's prelude trilogy first kill, but Xu Yang slapped them in the face with practical actions, proving that geniuses are not the same... People can understand it after watching it once.

After the watch was finished, Xu Yang clamped Sai Gang a little bit, then turned around and asked:

"Mr. Deng, then I started to set up?"

"Oh!"

"Oh!"

As soon as Xu Yang finished speaking, Deng and Xu nodded repeatedly like chickens pecking at rice.

"Hey!"

Xu Yang secretly glanced at the numb expressions of Deng and Xu, and couldn't help but sigh in his heart:
"Don't worry, what's more surprising is still behind?"

Thinking of this, the haze in Xu Yang's heart was swept away, replaced by confidence.

What follows is the biggest surprise of the whole session.

Clamping!

　Rejuvenating the country through industry, CNC technology!
