Daming: The system rejected my request for salted fish

While Wei Wu was delighted, Sun Chang continued to speak.

"According to the method you told us earlier, our blacksmith team used the blast furnace to smelt a harder steel."

"It's probably the high-carbon steel you mentioned. We also tempered it and then quenched it in salt water."

"Although its hardness cannot be compared with the tool heads used on machine tools, it still meets the requirements and can be used as a tool head."

Wei Wu didn't expect that in addition to the blast furnace, there would be an unexpected surprise, even high-carbon steel was produced.

Just as Sun Chang said, although the hardness of high carbon steel is not good enough, it can still be used to make knife heads.

The most common problem is that it is easy to wear out under continuous use, and the cutter head must be replaced with a new one after a period of time.

However, high-carbon steel can be produced continuously, so is frequent replacement of blade heads still a problem?

Wei Wu was already very happy about the success of the power station, and now he was even more delighted after hearing these two pieces of good news.

“Although the tool heads on machine tools are hard, they will eventually wear out over time.”

"Now with high-carbon steel, both the current machine tools and the machine tools we manufacture in the future are more advanced."

"No need to worry about blade wear. The worst that can happen is we just need to replace it a few more times. We can definitely afford it!"

Wei Wu immediately gave a positive response to Sun Chang's remarks.

"That's right, the problem with the blade has been solved, so the next thing is the oil. The oil you're talking about should be engine oil, right?"

"Motor oil?"

After Wei Wu finished speaking, Sun Chang immediately frowned, lowered his head, and muttered to himself while thinking:

"Engine oil? It's actually engine oil. No wonder it only seeps out a little bit when the machine tool is running."

"So its function is actually the same as the grease used in steam engine transmissions, which is to reduce friction."

"Yes! Although machine tools are processing tools, they are also machines, and machines cannot do without lubricants."

"It's a pity that I can't see the internal structure, otherwise I should have thought of this earlier. I'm so stupid!"

Sun Chang seemed to be talking, but in fact he was sorting out the thoughts in his mind bit by bit.

So when he was speaking, Wei Wu did not interrupt him, but just listened quietly beside him.

Afterwards, Sun Chang muttered to himself for a while, then suddenly raised his head and looked at Wei Wu.

"Mr. Vice President, can the grease we use on steam engines also be used on machine tools?"

"Of course, although those greases are not as effective as motor oil, they can indeed be used as substitutes."

Hearing this, Sun Chang was so surprised that he almost jumped up.

"The cutter head and the oil are both fine. As long as we build the motor, we can start making machine tools!"

After Sun Chang finished speaking, Wei Wu pondered for a moment, then slowly said:

"We'll try to manufacture the motor first. We can use high-carbon steel for the cutter head, but we can't always use substitutes for engine oil."

"It's made from animal fat. It's fine for a short time, but it will go bad if used for a long time."

"If sediment forms, it will not only emit a foul odor but also be difficult to clean up. More importantly, it will cause damage to machinery."

After hearing Wei Wu's answer, Sun Chang wanted to start manufacturing machine tools immediately.

It is true that the problem of mechanical lubricants does need to be solved, but that is not the most important issue.

Anyway, there are alternatives available now, so let's use them first, at least try to build the machine tool first.

As for the problem of mechanical lubricant, I will try to find a better one in the future.

However, just when Sun Chang was excited, he found Wei Wu frowning and nodding in deep thought.

In fact, what Sun Chang didn’t know was that as early as the emergence of the steam engine, lubricating oil was the problem that Wei Wu wanted to solve.
