Following.

Fang Bai woke up early in the morning, first recalled the knowledge points he memorized last night to strengthen his memory, and then got up to rinse his mouth and brush his teeth, went out to buy breakfast, and began to review his homework.

I went out at nine o'clock in the morning and rode around the rental house for a long time before I found a mechanical equipment repair shop.

The boss is a maintenance master, named Chen Fumin, about 40 years old, and has bearing disassembly tools in his shop.

Fang Bai described the problem clearly, and Master Chen said that he would know whether it was good to repair it or not by looking at things first.

A few minutes later, Fang Bai took Master Chen to the door, and after opening the door of the store, he pointed to the Mohs No. 5 spindle on the ground: "Master Chen, can this bearing be disassembled?"

You can't hurt the main shaft, there will be a lot of this kind of work in the future, and I'll look for you if you do it well. ”

Master Chen glanced at the spindle and was full of confidence: "Boss, there is no problem, I often disassemble and assemble the bearing to ensure that the spindle is not damaged." ”

"It's good to be able to repair it, plus replace it with a new bearing, how much does it cost to repair it?"

"The bearings are not easy to disassemble, and the installation is very troublesome, I have to boil the blister bearings, including not including the spindle to install back?"

Fang Bai thought for a while, he didn't need to do it again, it would be better, so as not to get dirty, and said, "Let's go together." ”

"That's estimated to be tossed for most of the day, fifteen yuan."

"Yes."

Fang Bai took out another cigarette and handed it to him, opening his own store to make money must be much higher than a part-time job.

Seeing that the business was done, Master Chen took the cigarette and said with a smile: "Then I'll go back and get some tools, and boil the oil by the way, a little longer." ”

After more than 20 minutes, Master Chen turned back again, and the tricycle had some more tools and half a barrel of hot oil.

Fang Bai didn't have anything to do, he didn't need to take a stool and sit next to him, he didn't need to hold his hands, watch how he changed, occasionally flip down the English book, and memorize the words.

Master Chan first soaked the new bearings in hot oil and then removed the homemade bearing extractor from the car.

Three levers are inserted in the inner ring of the bearing, 180 degrees of rotation is stuck, the tool has a bolt connected with the spindle threaded hole, after fixing the shelf, the next operating principle is somewhat similar to a wine corkscrew, little by little the bearing is pulled out from the spindle.

After about twenty minutes, several bearings were pulled off.

Next, after cleaning the spindle, the bearing changes begin.

The bearing is mounted on the spindle by the hot assembly method, that is, the principle of thermal expansion and cold contraction.

There is no clearance between the bearing and the spindle, and after the bearing is heated, the bearing ring expands, and it is easy to set it on the spindle.

The hot oil brought by Master Chen is used to soak the bearing, and when he removes the old bearing, the heating of the new bearing is enough.

The temperature should not be too high, otherwise the inside of the bearing will be deformed and cannot be used.

Hot-fitting bearings are much more convenient than dismantling bearings, and 5 bearings can be replaced in more than ten minutes.

Fang Bai saw Master Chen's familiar operation and logical process, and knew that he often did this work.

The next assembly is much simpler, it will be repaired in ten minutes, Fang Bai used the gold finger to detect, showing that the spindle bearing is already green, indicating that there is no problem.

Power on, turn it on, and there's no problem.

"Master Chen, it's been a hard work, I'll look for you again when I have a job in the future."

Fang Bai took out two bills and stuffed him with a pack of cigarettes, which made him a little embarrassed.

Master Chen said politely: "The boss is polite, as long as there is work, it will be a matter of one word." ”

"Alright, maybe I'll be looking for you in a few days." Fang Bai had an idea, so he should deal with the equipment in front of him first and then talk to him in detail.

Master Chen maintains a lot of equipment, and there should be a lot of contact with the boss, and there must be a lot of information in this regard.

"Well said, well said."

"Master Chen, do you know anything about second-hand machine tools? What is the price of a machine like mine if it is not faulty? ”

"I have some understanding, I have to check it first."

Master Chen first looked at the equipment situation, and then roughly operated it, and had an understanding of the performance of the equipment.

After a few minutes, after the inspection, he said: "Between 10,000 and 13,000, it depends on whether the other party is in a hurry to buy it." ”

For the sake of a pack of cigarettes, Master Chen also told the truth, and he didn't have the capital to collect it.

Fang Bai nodded: "Well, that's the truth." ”

"Boss, are you going to change hands?"

"Have this idea, look at the transaction price, if you have the channel, if you sell, I can give you one percent of the introduction fee, the time is limited to these two days."

Master Chen was silent, feeling that there was money to be made, and at the same time, he felt that Fang Bai, the young man, was also happy to give money, and said, "Okay, I'll bring the boss over in the afternoon to have a look." ”

"Yes, my name is Fang Bai, and I will stay in the store in the afternoon." Fang Bai said.

……

Half past two in the afternoon,

Master Chen really brought a middle-aged man over to see the equipment, and after seeing the equipment, he only offered 10,000 yuan, and Fang Bai didn't sell it, saying that he would think about it.

At five o'clock in the afternoon, Master Chen brought another boss over and quoted 11,000 yuan.

This price is a little far from Fang Bai's target price, but it is also acceptable, shaking hands with customers to probe the other party's information, detecting that the highest accepted price is 12,000, but I want to take a look at it more, and the advance payment is only six thousand, I want to use it for a period of time without a problem and then pay the final payment, of course Fang Bai does not accept this payment method.

The bosses that Master Chen is looking for are all the owners of small workshops, with limited funds, and the price is more ruthless.

Fang Bai quoted 12,000 and asked for a one-time payment.

Time is also money, and only when funds flow can you earn more, of course Fang Bai understands this truth, he plans to go to Wang Hengli tomorrow to see if he has ordered new equipment, if not, there is still a chance.

Of course, it depends on how much he bids, and if it is less, of course it will not be sold to him.

The next day, at nine o'clock in the morning.

Fang Bai came to Hengli Company, found Wang Hengli again, shook his gloves with him first, sat opposite him, and asked directly:

"Mr. Wang, you haven't bought a new drilling machine yet, have you?"

"Not yet, it's going to take a month, it's really a headache." Wang Hengli's chubby body sat on the sofa, like a Maitreya Buddha squatting and worried.

"Did you pay the deposit?"

"In two days."

Fang Bai clapped his hands in surprise: "Oh, then it's time for me to come!"

The equipment I bought from you two days ago had the main parts replaced, and it was finally repaired, almost like new.

I was planning to sell it to others, but I just thought that Mr. Wang, your recent production capacity here can't keep up, that is, there is a lack of drilling machines. ”

"Did you fix that drill machine? So fast? ”

"Yes, there is no problem at all, you see if there is any intention, or I will sell it to someone else."

Wang Hengli's brain didn't turn around all of a sudden, he sold the equipment the day before yesterday, and he repaired it and then sold it to him, what kind of operation is this?

sat up seriously, looked at Fang Bai who was smiling and drinking tea again, how did he feel that he had been pitted.

Of course, in other words, he is not unacceptable, it costs 20,000 or 30,000 yuan to buy new equipment, mainly waiting for time, so he also went to the second-hand market to see it in the past two days, and it is really difficult to find a suitable one.

After hesitating, he said to Fang Bai: "Let's take a look first, where is the equipment?" ”

Fang Bai said: "It's next to Oubei No. 1 Middle School. ”

"You said two days ago it was nearby."

Wang Hengli suddenly remembered Fang Bai's words the day before yesterday, and asked the forklift master to help him deliver the equipment, saying that it was not far, it was nearby, and he thought it was within three or four hundred meters of his company.

This special place is nearby, there are two or three kilometers of road.

Thinking of this, his brow furrowed.

Fang Bai knew that Wang Hengli was complaining about him, so he smiled cheekily: "That's right, it's nearby, I'll ride for a while, and it's not dozens of kilometers away." ”

When Wang Hengli heard this, he glanced at the ceiling and was a little speechless.

After a little silence, feeling a little helpless, he patted his thigh and stood up: "Then let's go." ”

The two left the office, and Wang Hengli went to the workshop to call Ma Jingsen and a driller, and asked them to bring a few iron plates and calipers to test the equipment by the way.

When Ma Jingsen and the driller saw that it was Fang Bai, they knew that the equipment to be tested was the drilling machine sold by the company two days ago, saying that it had been repaired.

This stunned the two of them.

But it's hard to say anything, put the board in the trunk of the boss's car, and then get into the boss's Poussin car and set off together.

Fang Bai rode in front to lead the way, pedaling hard.

Ma Jingsen sat in the co-pilot, looking at Fang Bai, who was kicking happily, and felt that the feeling in his heart was quite complicated: What kind of play is this?

What's the operation?

Taking the equipment back to repair it and selling it to the original boss, this kind of operation, Ma Jingsen feels that he is not so thick-skinned.

On the one hand, he hoped that Fang Bai would not make any money, and on the other hand, he hoped that the equipment would be repaired and the production problem would be solved as soon as possible, which would have made him worry recently.
