This also involves whether the stress on other parts is uniform. If it is not uniform, it will cause some parts to age first, and then there will naturally be oil leakage.

And in these details, the Japanese have almost done the best.

This is what others' assembly masters, who explore, pass on, help, lead the next generation of technical masters, accumulate and pass on them.

On the other hand, we...

It can only be described in ellipsis. They are not worthy of the word "hehe".

For the same example, there is Zeiss from Germany.

You must know that the worker of Zeiss sunglasses in Germany can no longer be called a worker, and you must become a master.

Especially for the highest-level lens polishing, almost all the craftsmen from the same family are used.

And the craftsmen in this family have to work hard to polish the lens industry for three generations...

This is really not an exaggeration...

There are also watchmaking companies in Switzerland, especially those famous watch companies, and watchmakers used.

Those precision gears are processed, polished, and then assembled together.

That really requires the experience of a family, generations of accumulation, and then inheritance.

Otherwise, if you change someone, you will give you the same parts and let you install them, and you will not be able to install them.

If you walk for a long time, errors will occur, which is most obvious in the watch industry.

The more famous the brand is, the more accurate the watch is prepared by the master.

Even for decades, there will be no error.

But if it is a watch prepared by an ordinary master, it may take a year, and there will be an error of more than ten seconds or one minute.

For ordinary people, this may not be much.

But for industries that require extremely strict accuracy, that is not possible.

For example, this precision instrument manufacturing industry...

For example, you can use various pressure gauges and depth detection gauges on submarines. If you are not accurate, then it won’t work.
