The students talk about party history
Member of class 1 of the institute of smart manufacturing, 19 number control technology (academies)
I am a student in 19-digit-controlled apprenticeships, and today i tell you about our professional history, our first digital-controlled bed。
In 1959, the first digitally controlled bed in the new china was born at the first machine-bed factory in beijing. The machine-bed industry is not large compared to other industries. From nothing, however, from the “sniffing” to autonomous research and development, the new chinese machine industry has witnessed the growth and growth of our country for decades as a “mother machine” for the manufacturing of equipment and, indeed, industrial development in general.

In 1958, the centre introduced the slogan “behind america and england”. It was in that year that the state handed over the project for the development of digitally controlled beds to the university of tsinghua and beijing's first machine-bed plant, with the mission code-named “task 102”。
The development of numerically controlled bed development is in four parts: the hydraulic system of the machine bed is under the responsibility of the precision system; the digital control component is under the responsibility of the automated control system; the step-in motor and its driver are under the responsibility of the electrical system; and the beijing machine-bed plant, which acts as the unit of foreign cooperation and the unit of delivery, is responsible for the provision of the bed and maintenance.

There's no one who knows what to do with the control bed. At this point, a professor from qinghua brought back from the soviet union an advertisement with a photo of the machine bed, with a large 1-metre-high cabinet next to the machine bed, the digital control system, and several performance indicators, which became the only information available to the design group. But at that time, because of the scarcity of the original device, it was necessary to think of ways to solve the problem, and in their constant innovation, they had been struggling with the difficulties, the critical equipment of the control machine, and the walk-in machines were designed by the comrades themselves.

On the night of the summer and autumn of 1959, our first digitally controlled bed was finally developed, marking the digitalization of china's garment industry. At the time, developers had developed two little programs: one with a pentacle shape and the other with the word "welcome" and when a piece of iron turned into pentagrams and "welcome" the visitors found it very new, but since then, due to the foreign technology blockade and the domestic infrastructure constraints, our digital-control technology has not been well developed (li hua-ryung)
This situation continued until the late 1970s. Since then, china has embarked on a spring of reform and openness, and digitally controlled machines have been incorporated into national development priorities. At the same time, a period of rapid development has been ushered in through international cooperation and exchange of digital machines. In august 1979, the jenan first machine plant signed a high-speed precision machine-bed-processing agreement with the world-renowned machine-bed manufacturing firm mazak, the japanese mountain chair, which pioneered international technical cooperation in this field.

The data show that from 1980 to 1995, nearly 150 machine-bed technologies were introduced in the country, and that almost 1,000 types of digitally controlled machine-beds were developed in aggregate. Annual production of digitally controlled machine-beds rose from 692 in 1980 to 7291 in 1995. After entering the new century, the development of the machine-bed industry in our country was described as “high sesame flowering”. The inclusion of high-quality digitally controlled machines and basic manufacturing technologies in the country's major scientific and technological specialization is a sign that the country is moving forward in the direction of the country, with the joint efforts of its people, towards the country with the most powerful machines.

Thank you for watching. Bye。
