The so-called secondary processing, to put it simply, is to carry out more precise processing on the surface of the parts that have been processed once, so as to achieve higher precision of the parts. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

Compared with the primary processing, the secondary processing is naturally more difficult.

First of all, knife alignment is a problem.

After the parts have been processed once, they will definitely produce dimensional accuracy, shape accuracy, position accuracy, and interrelationship, which virtually adds a lot of difficulty to the secondary processing of parts. If the knife is not aligned correctly, it may cause irreparable damage to the entire part.

The so-called difference is a thousand miles.

That's what it means.

Next, the level of the operator is very high.

Because, the parts that generally need secondary processing will have high requirements for accuracy, and novices will not be able to complete the operation, and they must be senior fitters or above.

Of course, compared with secondary processing, the advantages of one-time molding of parts processing are more, one is the overall rigidity of the parts, long service life, and high precision; Second, it is stable. Therefore, as long as the parts can be formed in one time, no one will choose secondary processing.

The reason why Tianze chooses secondary processing is based on two reasons.

The first reason is that the machine tools of Hongxing Machinery Factory are not good enough, although they are already top in China, and they can also process qualified valves, but they cannot guarantee the pass rate. I'm not afraid of wasting time, I'm afraid that there are not enough materials! It may be that all the blanks provided by Bombardier have been tossed up, and the quantity specified in the contract cannot be processed.

The second reason is to save time.

This time is not someone else's, but Tianze's own. Think about it! Tianze can completely hand over the first processing to Hongxing Machinery Factory to complete, Tianze only needs to complete the secondary processing, how much time can this save Tianze?

"Team leader, are you sure?" Ma Dalong said worriedly.

It's not one, it's not two parts.

It's thousands!

"It's okay, since I dare to do this, I naturally have a lot of certainty. You arrange for someone to put the finished valves together, and I will find time to do it, and now I have something to do and leave first. Tian Ze patted Ma Dalong on the shoulder and said confidently.

"Alright then!"

Ma Dalong could only say helplessly.

……

Ignoring Ma Dalong, who was still worried, Tianze left the No. 1 workshop directly, went to the office area to pick up Lele, and then drove back to the universal repair shop.

"Mom!"

Lele suddenly shouted.

Tianze looked up, isn't it! Qiu Xuejiao was standing in front of the repair shop and watching, holding a thermos cup in her hand, which was obviously much haggard compared to the previous few days.

"Lele, have you been obedient these days?" Qiu Xuejiao hugged Lele and asked excitedly.

"Lele is good, I don't believe you ask my brother." Lele said proudly.

"Hmm!" Qiu Xuejiao touched Lele's little head, stood up and said gratefully to Tianze, "Xiaotian, these two days have really troubled you, if you didn't help take care of Lele, I really don't know what to do, how can I thank you?" ”

"Sister Qiu, don't mention this, Lele is my sister." Tian Ze waved his hand, hesitated and asked, "By the way, how is he?" ”

Tianze didn't mention his name, but Qiu Xuejiao understood.

Tian Ze refers to Zhang Jun.

"He didn't have any big deals, the doctor said it was because of too much mood swings, and he would be fine as long as he recuperated for a few days, but he still needed to be hospitalized for another two days of observation." Qiu Xuejiao also did not mention Zhang Jun's name, but replaced it with 'he', obviously not wanting to mention Zhang Jun more in front of Tianze.

"By the way, I'm here to pick up Lele this time, and I'm going to send Lele to my mother." Qiu Xuejiao took Lele's right hand and said to Tianze again.

"That'...... Isn't Lele going to be able to see his brother? ”

Lele said anxiously.

"Just stay for a few days, and when Dad is discharged from the hospital, Mom will pick Lele back, and Lele can see his brother!" Qiu Xuejiao hurriedly comforted her.

"Okay!"

Le Le nodded sullenly.

"Lele, when you come back, my brother will take you to the zoo." Tian Ze also comforted.

"Really?" Lele said happily.

"Of course it's true." Tian Ze affirmed.

"Alright, goodbye brother, we still have to hurry." Qiu Xuejiao looked at the watch on the bowl in her left hand and urged.

"Goodbye, brother!" Lele shook his hand.

"Goodbye, Lele!"

Seeing Qiu Xuejiao disappear into the crowd with Lele, Tianze turned around and prepared to open the store. Sou! At this time, a figure suddenly rushed to Tianze's body, and Tianze, who was taken aback, kicked out his right foot without thinking about it, and kicked the opponent's belly fiercely with lightning speed.

Yes! With a cry of pain, the other party was kicked and sat on the ground.

"Hey, why are you?"

Looking at Zeng Tianming, who was sitting on the ground, Tianze looked surprised.

"Big ...... Teacher, you are really ruthless! Zeng Tianming rubbed his stomach and stood up, with a wry smile on his face.

"Who made you haunted?" Tian Ze was not embarrassed at all, but blamed.

When encountering such an unreasonable Tianze, what can Zeng Tianming say? I could only look at Tianze with a resentful face.

"Where's the thing? Didn't you say there was something good to show me? ”

Tianze hurriedly changed the topic.

As soon as he mentioned the matter, Zeng Tianming immediately put away his aggrieved expression, first looked around as if he was a thief, and then whispered in Tianze's ear, "Master, I really have something good to show you." ”

"That's it?" Seeing Zeng Tianming like this, Tianze suddenly became interested, and pointed to a long wooden box in Zeng Tianming's arms and asked.

"Master, don't underestimate it, it's a priceless treasure in it!" Zeng Tianming patted the wooden box again, and said mysteriously.

"Hang people's appetite, take it in three days." Tian Ze snatched the wooden box and waved his hand at Zeng Tianming.

"Master, be careful!" Zeng Tianming reminded nervously.

"Got it, got it." Tian Ze's face was full of disapproval.

It wasn't until Tianze entered the store that Zeng Tianming reluctantly withdrew his gaze, and then disappeared into the flow of people step by step.

……

It's also strange to say, since the door of the store was opened, there has been an endless stream of customers who have come to repair items, and Tianze actually didn't have time to open the wooden box to take a look.

The so-called the more you can't get something, the more you want it, Tianze is in this mood now. I feel as uncomfortable as a kitten in my heart, anxious to know what is in the wooden box?

In the end, Tian Ze simply closed the store early, took the wooden box and drove back to the rented apartment. After buying a roast duck at the roast duck shop outside the apartment, Tianze hurried back to the apartment.

"Let me see what kind of baby you are?" Throwing aside the paper bag containing the roast duck, Tianze couldn't wait to open the wooden box.

"A painting? Or a pair of words? What appeared in front of Tian Ze was a yellowish scroll.

Tianze didn't hesitate, and took it out.

rudely spread it on the table.

"Hey, it's a painting."

Tian Ze was surprised.

It's not that I'm surprised that the scroll is a painting, after all, the scroll is a cultural relic, except for the painting is the word, there is nothing to be surprised about. What really surprised Tianze was that this painting was simply 'miserable', and he didn't know that it was the loser's gadget, and a good painting was actually splashed with black ink.

The proportion of ink has reached at least 60% of the canvas.

As you can imagine, the painting was damaged.

It's almost unrecognizable.

Tianze only saw a mountain in the upper right corner, and a little sea water on the left, which was covered with red sunlight. The mountain was not high, but it stood still, and the sun in the sea was as red as if it were going to set the whole surface of the sea on fire, and the rest of the sea was inky black.

"Then let me restore your true face!" A glint flashed in Tian Ze's eyes.

Without any hesitation, Tianze summoned the PS system.
