cq904传奇电子官网:Development History of Abrasive Tools in China(1)

December 18, 1978. Beijing.
The Third Plenary Session of the Eleventh Central Committee of the Communist Party of China, with great turning point, opened the curtain of the era of China’s reform and opening up.

Since then, China has embarked on a new journey.
All walks of life have undergone tremendous changes in the past 40 years.

We have been trying to describe the abrasive abrasive industry through different forms or data. It seems that neither the listing of existing data nor the dialysis of hot spots can vividly show the changing process of the abrasive industry.

Abrasive abrasive industry is an indispensable role in industrial production, but because it is relatively rare in everyday life, people are relatively “unfamiliar” with it. In order to make abrasive abrasive more “civilian” to present in front of you, we take “interesting” as a lead and introduce the development of abrasive abrasive industry.

This year is the 40th year of reform and opening up. Crossing the river by touching the stones, we have come to the fore. The rise of great powers has formed our impression of reform and opening up for 40 years. Over the past 40 years, China’s development has been tremendous. Many industries grow from scratch, from small to large, from big to strong, until they become the protagonists on the world stage. It is the leap-forward development of many industries that has painted a magnificent picture for China after its reform and opening up.

After the reform and opening up, a large number of private abrasive tool manufacturing enterprises emerged in China. There are many excellent enterprises that promote the development of the industry and technological progress. They make continuous efforts to develop and grow, but also contribute to the progress of the entire industry.

In this issue, we will take 1978 as the starting point and show the changes of abrasive industry in the 40 years of reform and opening up by combining several representative topics or things.

Talking about “the Second Donkey Killing Plant”

—— The Development Course of Abrasive Abrasives from “Unfamiliar” to “Familiar”

“How can I get to the Donkey Workshop of the Second Donkey Killing Factory?” This is what people in the western suburbs of Zhengzhou often heard in the late 1950s and early 1960s. You may be unaware that the slaughter industry in that era was so large-scale that it was divided into different factories and workshops. In fact, this is more like a joke, because the original content of the question is: How can I get to the alumina workshop of the second grinding wheel factory?

(Note: Grinding Wheel in chinese SHALUN砂轮,sounds like SHALV杀驴-Donkey Killing is free translation)

Yes, people in that era were unfamiliar with the grinding wheel. Even those who were assigned to the preparatory office around 1954 did not know what abrasives were made of before they worked.

China is one of the oldest countries to adopt grinding methods. In matriarchal society, people have begun to use the simplest stone tools, which are made by friction between stones. People use these simplest tools to hunt and cultivate. At that time, although people’s clothing was simple, they still had to be assisted by blades, which could not be separated from grinding. There are idioms of “cutting, negotiating, cutting and grinding” in the ancient science masterpiece “Tiangong Kaiwu”, among which “grinding” refers to grinding processing.

Since the reform and opening up, more new things and technologies have poured into China, and the abrasive industry has developed rapidly.
From the evolution of several types of abrasives, we can see the development track of abrasive industry after the reform and opening up.
