West China Heavy Industry, located in Qingbaijiang, Rongcheng, is a medium-sized machinery manufacturing enterprise, producing automobile and ship transmission shafts, bearings, gears, brake pads...

Because of business needs, four DMG [five-axis machining centers] were imported from Germany in the past two years, and although the price of this machine is not cheap, it is also stable to use.

In two years, there have been almost no failures!

Just yesterday, the staff was ready to work overtime to produce a batch of parts, but suddenly found that the accuracy of one of them suddenly dropped, about 10%.

There is no trauma / normal operation / no fault, the accuracy can not be improved, it is useless to debug, I don't know what the specific reason is, and the technicians in the factory are also confused.

It's so weird, I've never encountered it at all! The number of [five-axis machining centers] imported from Germany is relatively rare in China, and it takes a week for the manufacturer to repair.

Are you kidding? Wait a week?

Lost profits, wages, productivity, at least 200,000 in total! Finally, there is an order, and the downtime is a pure waste of money and increases the burden on other equipment.

You have to find a way to fix it, hurry up!

Repair shops/dealers/technicians, who can solve the problem, have a reward; Some employees posted on the machinery forum for help, looking for help from the big guy.

Not to mention, there are a lot of people replying!

System/Fixture/Tool Magazine/Tool/Power Supply... All parts were examined, no abnormalities were found, and when they were not hopeful, they received a reminder --

"Please check the spindle grease."

In just eight words, it is bland, but it makes them feel that the mouth is suddenly open, and the spindle is grease! Immediately, someone guessed the cause of the anomaly - metal powder penetration.

Last month, this five-axis machining center produced a large number of hard and brittle lead-containing alloy carved workpieces, and the powder particles were very fine.

After cleaning up, turn it back on---

The accuracy is restored, everything is in normal condition, and the problem is solved without spending half a penny! The boss Long Yan Dayue, contacted [Lingfeng Technology] who helped remind him, and sent a red envelope to thank him.

No more, no less, Geely's 8888 yuan!

Compared with the loss of more than 200,000 yuan, a few thousand yuan seems a bit insignificant, let's talk about it~ Jiang Feng is already very satisfied in his heart! Lament that technology is king.

A total of 8 words, 1111 yuan per word, we can barely count a thousand words, right? I have to earn more than I used to work hard for two months.

"Hmm~~ Just buy a new motorcycle!"

In the middle of the night today, I earned more than 10,000 yuan, and I bought an ordinary Haojue/Qianjiang/Yamaha motorcycle, which was enough and more than enough, five or six thousand would do.

"Which brand do you think is the best?" Jiang Feng asked Wei Da Wei Er with a smile, he was in a good mood, and he was very happy that the balance of his WeChat wallet was 11,508 yuan!

Wei Er suggested: "Report to the boss, I think we should buy a pickup truck, motorcycles are not suitable, and we can't ride a bicycle when we go out to undertake maintenance business in the future, right?"

"Uh~ That's right~ Let me think again..."

Jiang Feng was stunned, this is a problem, he will definitely have to buy a pickup truck in the future, but the money is not enough now.

The deposit of more than 20,000 + the money earned today is less than 40,000 yuan! The cheapest Great Wall Fengjun costs at least 60,000 or 70,000 soft girl coins, which is still a big difference.

Besides, Jiang Feng can't buy Fengjun, that brand is too rubbish, and he has the money to buy a better one! It's just that there is not enough money at the moment, so I am waiting for a repair order.

Said Cao Cao Cao arrived, and the QQ prompt sounded--

[Your friend verification request approved]

[Changshan Salt Factory-Logistics Section Chief: OK, come to our salt factory before noon tomorrow, call us, and if it is repaired before the end of work, you can pay on the same day.] ]

Jiang Feng replied: "Hmm~ no problem!"

It turned out to be the logistics department of the Changshan Salt Factory, and I said that I had two relatives who worked there, and the salary was so low that people vomited blood, and the monthly salary was not even 1,500.

The reason is very simple, the efficiency of the salt plant is low, the mining cost of rock salt is very high, and the price of salt is cheap; Naturally, the economic benefits will not be too good, and the wages of employees will be poor.

The method of mining rock salt [well salt] is ---

1. Use a boiler to boil hot water and inject it into the salt mine

2. After fully dissolving, extract again

3. Add potassium iodate and sodium sorbate

4. Heat and evaporate to precipitate edible salt

5. Quality inspection, packaging and delivery

In this process, the boiler is very critical, the salt plant needs a huge amount of hot water, and its large boiler will work for five or six hours tomorrow, but fortunately there is not only one.

Moreover, the efficiency of the salt factory is not good, and the backlog of inventory can supply the whole province for two months! The Changshan Salt Factory is a very famous salt factory in the province, and the productivity is quite terrifying.

In the past, there were rumors that there was a shortage of edible salt, and the salt people could tell you responsibly--- pure nonsense! The large salt factory is running at full capacity, enough for you to eat...

Therefore, even if a boiler is broken, the salt factory is not in a hurry to repair it, and offers a reward of 15w soft sister coins to recruit a private team to see, why is the boiler leaking?

Several repair companies have already gone to see it.

Helpless! The boiler is very old, and many parts need to be repaired, and 15W is a bit of a loss; The salt plant is advised to replace the new gas boiler, the cost is cheaper~

The salt factory also wanted to replace it, but it didn't have the money to buy a new boiler, so it could only be repaired, and the highest bid for maintenance was only 150,000 yuan, and it was never discussed.

The other party kindly reminded Jiang Feng: [The electric boiler of our salt factory is from 2008, more than 9 years, and it has been repaired several times before, but I am afraid it will be overhauled this time!] ]

Jiang Feng agreed, overhaul afraid of an egg? Horizontal and vertical is the work of cutting and welding, and the material input is not large.

The remuneration is 150,000 yuan, and the profit is more than 95%!

The money for buying a car/motorcycle/equipment/things/decoration depends on this time; Let Wei Dawei 2, Wei 3, Wei 4, they pack up the equipment and materials, and set off early tomorrow morning.

The toolbox, welding machine, cutting machine, and materials have been sorted out and improved, and the performance has been strengthened a lot.

It was already early in the morning, Jiang Feng went back to his room to sleep.

Silicon-based mercenaries do not sleep, and are arranged to sit in the living room to keep on guard, part-time bodyguard work.

There is only one bedroom in the factory, and the toilet, kitchen, and bathroom are basically complete, although the conditions are simple, but the daily life can be completely solved, and the area is wide enough.

Maintenance soldiers can also recall the Recruiting Depot.

There were too many things to experience today, and Jiang Feng felt a sense of uneasiness in his heart, and it was a mess, so he ordered Wei Dawei to be on duty to have a sense of security.

Awesome [Recruiting Depot] mercenaries

Amazing [Super Encroachment System] glasses

I'm afraid it's a dream, and when I wake up, it's broken...

Fortunately, all this is true, Jiang Feng got up early the next morning, the system glasses were still there, and the mercenaries had already completed the modification work and packed up their things.

"Let's go! Changshan Salt Factory, repair boiler~"
