Chapter 44
"You can make the decision?" Tian Ze had a look of disbelief.

Millions of dollars in outsourcing fees!How can Zhou Tong, a workshop director, be the master?Li Zexin, chairman of Hongxing Machinery Factory, is about the same.

"I can't make the decision, but my brother-in-law Li Zexin can make the decision! When I came, he had already delegated the power to me, and I have full authority to handle this matter. You can rest assured about this." Zhou Tong patted his chest Guaranteed.

Now, Tianze understood.

Zhou Tong is deceiving him!
Tianze didn't believe that Li Zexin would be so stupid as to give away millions of dollars in outsourcing fees.The reason why Tianze opened his mouth just now was just to tease Zhou Tong. Unexpectedly, Zhou Tong was not thinking of bargaining, but directly had bad intentions.

"Okay! I'll do this work."

Tian Ze smiled.

"Great, then let's go to the factory now." Zhou Tong said excitedly.

"Okay!" Tian Ze nodded.

When he went to pick up Lele from Grandma Sun, Tianze drove away in his own Daben.Zhou Tong looked at the back of Daben's car and was stunned for about ten seconds before he came to his senses. He opened the door of a BJ Hyundai and followed Daben and disappeared into the traffic.

An hour later, the two vehicles arrived at the advanced manufacturing base in the east.

This is a huge industrial cluster.

With the large industrial zone and Biling high-tech zone as the core, it gathers the Shapoo, Tiantou, Jinsha-Shatian industrial zones, and Shangpingshan Liulian industrial zone, and its development is oriented towards electronic equipment and chemical industry bases.

The equipment industry focuses on the development of CNC machine tools, transportation equipment, electrical machinery, new energy, power transmission and transformation, precision machinery manufacturing, etc.; also utilizes high-tech parks such as large industrial zones to vigorously develop high-tech industries such as digital audio-visual, IC manufacturing, biomedicine, and fine chemicals ; In terms of traditional industries, promoting the agglomeration and development of advantageous industries such as furniture and bicycles is a key project of the Shenzhen Municipal Government.

Hongxing Machinery Factory is built in it.

Specifically in large industrial areas.

……

With Zhou Tong's leadership, Tianze easily entered the Red Star Machinery Factory.Tianze didn't go to the factory right away, but came to the office area, and asked Zhou Tong to find a beautiful female clerk to play with Lele. Tianze spread out the blueprints that Zhou Tong took out and began to study.

The production of parts has never been a simple matter, and the more complex the structure, the more complicated the machining process of the parts.Specifically, the processing of a part can be subdivided into: preparation of raw materials, preparation process, blank manufacturing, machining and heat treatment of parts, and part inspection.

Among them, the preparation process is the most important.

To make a metaphor, if you want to calculate 1+1=? , then you must first know the law of addition, and the process is equivalent to the law of addition.

The parts processing process is rarely single, and it is composed of several processes arranged in a certain order, and the process can be subdivided into installation, station, work step, and cutting.As for what is the process?To put it vividly, a part has holes, bevels, grooves, etc. The process is to arrange which machine tool to use, and first complete the processing of the part.

Tianze looked at the part drawings provided by Bombardier.

A valve drawing.

Don't underestimate this valve drawing, this is not the valve of the faucet, but the valve of the aircraft cabin door.Not only is the structure more complicated, but also the material requirements are high. Forging of one-piece aluminum alloy requires a margin of 3mm on one side, a margin of 5mm on the height, and a zigzag surface roughness of Ra0.3. The difficulty lies in Ra0.3, which is almost It is close to the limit of special precision precision Ra0.2.

"Tianze, can you get it out?"

Zhou Tong said with a worried look.

"can."

Tianze believed in himself.

"Are you really sure?"

Zhou Tong said in surprise.

"It's fine if I say yes, don't bother me here." Tian Ze waved his hands impatiently, as if chasing away flies, and didn't pay attention to Zhou Tong, the master, at all.

"Okay, okay, I won't bother you." Zhou Tong didn't care at all, and said with a smile on his face.

After leaving Zhou Tong casually, Tian Ze picked up the banknotes next to him and began to calculate and write the valve process.Since it was a private job, Tianze didn't write it according to the standard format, but wrote it as convenient as possible. In many places, he used ghost symbols that Tianze himself could understand.

This busy work lasted two hours before Tianze compiled a simplified version of the process.

"Tianze, have you compiled the process?" Zhou Tong came up again.

"Okay!" Tian Ze stretched beautifully, and let Zhou Tong take the compiled process to check.

"Then let's just test one?" After looking at it for a long time, Zhou Tong didn't understand what was going on, so he could only return the process to Tianze.

Nonsense, Zhou Tong is a student of archaeology. Although he has been the workshop director for several years, he can only understand some simple mechanical diagrams, and he can't understand the complicated ones, let alone Tianze's process of adding materials. .

"Okay! Let's go then!"

Tianze walked away with the process in hand. It was already past five o'clock in the afternoon and the sky was getting dark. If he didn't hurry up, he might not be able to make a part today.

……

When Tian Ze and Zhou Tong came to workshop No. [-], most of the workers in the workshop had already left work, leaving only a few cleaning workers.

"Master, you are here!"

A young man greeted him.

Tian Ze didn't even look at the young man, and walked straight to a lathe.This is a CNC lathe made in Switzerland. After turning it on, Tianze started programming on the console and entered the program he had just written.

As for why Tianze ignored the youth?
There is a reason for this, of course.

The young man's name is Chen Xiaolong, and he is really Tianze's apprentice, but this guy has shamelessly betrayed Tianze and secretly helped Zhou Tonglai deal with Tianze.If it wasn't for an accidental discovery, Tianze might have been kept in the dark until now.With Tianze's violent temper, he didn't kick Chen Xiaolong directly, the sun was already coming out from the west, so how could he give Chen Xiaolong a good look?

Chen Xiaolong looked at Tianze's back, a trace of sadness flashed in his eyes.

Chen Xiaolong knew that the two of them were passers-by from now on.

Is it really worth it?
Zhou Tong didn't care about Chen Xiaolong's complicated heart, he secretly pushed Chen Xiaolong and gave him another wink.Chen Xiaolong quickly put away his complicated emotions, and nodded quietly.

A gleam of joy flashed in Zhou Tong's eyes, and he strode towards Tianze.

……

It took half an hour for Tianze to compile the program, place the blank provided by Bombardier on the CNC lathe, and then align the tool and start processing.

Amidst the low motor sound, the blank began to be cut rapidly.

Seeing Tianze staring closely at the blank, Chen Xiaolong couldn't help sneaking up to him.Tianze ignored him and let Chen Xiaolong investigate the processing of the workpiece.

After changing five knives, the blank is fully formed.

But the lathe did not retract.

Still turning.

"System, load the workpiece into the machine tool." Regardless of the confused Chen Xiaolong next to him, Tianze called directly in his heart.

"Drip! Start loading." In a burst of electronic sound, a holographic image appeared in the blue three-dimensional space of the ps system, which was the completed holographic image of the valve.

"Turn on the scan function."

Tian Ze ordered.

Almost immediately, the ps system completed the scan, and the electronic sound rang again, "Drip! The scan is complete, and the target is a mechanical part."

"Compare with the previously loaded part drawings." Tian Ze continued to order.

"Drip! Start comparing."

"Drip! The comparison is complete. After comparing with the part drawing, the dimensional accuracy of the workpiece is IT8-IT7, and the surface accuracy is Ra0.5, which does not meet the requirements of the drawing at all. Do you want to activate the system's removal function?" It takes only three seconds, ps The system completes the comparison.

"Turn on!"

Tian Ze immediately said.

"Drip! Turn on the removal function, the removal progress is 1%, 2%... 99%, 100%, drop! The removal is complete, and the workpiece has reached the requirements of the drawing." In the cold electronic notification sound, the holographic image of the workpiece began to change , the surface can be clearly seen to become smoother.

Of course, what changes at the same time is the workpiece in the machine tool.

It's just that it's impossible to see clearly because of the glass.

squeak!The lathe compartment opens...
