Wuzhong 4 Machine Tools: World's "First Set"

Recently, the national independent research and development of major equipment and extreme manufacturing products - Wuzhong 4 overweight limit machine tools delivered in Tianjin, China's heavy machine tool development history ushered in a new milestone.

These 4 machine tools are all domestic "first sets", of which two are major national special projects. They break the limit to create foreign technology blockades and create many of China and even the world.

The country's major special 28-meter CNC vertical milling lathe, the largest processing diameter of 28 meters, processing height of 13 meters, the processing error of 0.02 mm, thinner than the hair, are the world's best, to fill the gap between the domestic machine tool processing large nuclear power key parts. National key special project DL250 type NC super-heavy sleeper, bearing 500 tons, is the highest in the world, providing key processing technology guarantee for the development of China's strategic equipment.

The ground-level milling and boring machine with a boring axis of 320 mm in diameter is the world's largest product specification. The CNC gantry boring and milling machine with a 10 meter long gantry spacing is the first in China and rare in the world.

Heavy-duty machine tools are the hallmark of the country's industrial base. In 2009, in a confrontation with a strong opponent, Wuzhong won a bid of nearly 200 million yuan in a single order contract for Tianjin Cerui Co., Ltd., manufacturing 4 sets of domestic "first sets" of machine tools. Every machine tool has to sprint to the top of the world. It is unprecedented that multiple limit devices are manufactured at one time.

Huang Zhao, chairman of Wuzhong, said that in the global machine tool industry, Wuzhong is the only company that can manufacture the world's largest four different types of machine tools. “Hubei made” represents China's first priority in creating world-renowned heavy machine tools. Machine tool countries Russia, Germany.

Wu Bulin, executive vice president of the China Machine Tool Industry Association, said that the delivery of Wuzhong's four heavy machine tools could shorten the world gap in China's nuclear power, shipping, space, and military industries.
