In recent years, with the rapid development of the equipment manufacturing industry, China's heavy-duty machine tools have achieved fruitful results. Many world-class CNC machine tools have been successfully developed. One by one, the "made in China" which can be rated as a national treasure is well known all over the world.

World large die forging hydraulic press

China Erzhong 80000 ton hydraulic press

China Second Heavy Machinery Group successfully built the world's large die forging hydraulic press. This 80000 ton die forging hydraulic press is 27 meters above the ground, 15 meters underground, 42 meters high, and the total equipment weight is 22000 tons. It is one of the important contributors to the successful flight test of China's domestic large aircraft C919.

Giant die forging hydraulic press is a national treasure level strategic equipment that symbolizes the strength of heavy industry. It is an important symbol to measure a country's industrial strength and military capability. It is one of the few countries in the world that can develop it. At present, only China, the United States, Russia and France have more than 40000 ton die forging presses in the world.

This 80000 ton die forging hydraulic press in China broke the world record maintained by the former Soviet Union for 51 years, which also marked the end of the era when China's key large forgings were subject to foreign countries.

What is even more shocking is that Tsinghua University has developed 160000 tons of die forging hydraulic press. Only because China's manufacturing industry does not need such a large die forging hydraulic press at present, once the country needs it, it can be produced. 160000 tons is more than twice that of the 75000 tons press in Russia and 3.5 times that of the 45000 tons press in the United States.

With such amazing figures, I believe that China will become the new overlord in the world's forging industry in the future

World large and Super Heavy CNC horizontal machine tool

Wuhan Heavy Machine Tool Group

World large diameter propeller machining machine

Medium transmission heavy seven axis six linkage machine tool

Zhongchuan Heavy Machine Tool Co., Ltd. has independently developed the world's large-diameter seven axis six linkage propeller processing machine, which can process 11 meter diameter propellers.

The quiet performance of naval submarines is the core indicator to measure the combat effectiveness of submarines. For a long time, the noise of Chinese submarines has been widely criticized by the outside world. The US military even threatened that Chinese submarines can be detected as soon as they leave the port. The core component that restricts the noise of submarines is the propeller at the tail of submarines. The commissioning of the seven axis six linkage propeller processing machine tool will greatly help the qualitative change of the noise performance of submarines of the Chinese navy.

Seven axis six linkage machine tool is a large and complex machine tool in the world. The successful development of this machine tool indicates that China's machine tool enterprises have the strength to compete with the world's top machine tool enterprises in the international market

In addition, the CNC heavy-duty crankshaft compound processing machine tool with Chinese independent intellectual property rights, full functions and high precision has also been successfully developed in CITIC Heavy Industry, which has enabled China to master the manufacturing technology of heavy-duty marine crankshaft processing machine tool, and has freed itself from the situation that large-scale marine crankshaft was heavily dependent on imports. China has also become the third country in the world that can independently design and manufacture crankshaft processing equipment after Germany and Japan

World's largest vertical turning and milling machine

CNC heavy duty machine tool with a diameter of 25 meters

Qizhong CNC Equipment Co., Ltd. successfully trial produced the world's large vertical turning and milling machine.

In addition, Qizhong has successfully independently developed China's first CNC heavy-duty crankshaft milling machine tool (also known as "whirlwind machine") and successfully processed China's first large-scale ship crankshaft.

China has become the third country in the world to independently design and manufacture crankshaft processing equipment after Germany and Japan, which marks that the independent innovation ability of large-scale CNC machine tools in China has reached the high-quality level and paves the way for the development of large-scale ships in China.

The world's first new five axis hybrid machine tool

Qiqihar second machine tool group

Qiqihar No. 2 machine tool group successfully developed the world's first new five axis hybrid machine tool - xnz2430 new large gantry five axis hybrid machine tool and Asia's largest skcr165 / 1200 CNC fiber winding machine.

At present, foreign countries have imposed a technical blockade on China on large-scale five axis CNC machine tools. China needs to spend a large amount of foreign exchange to import such equipment from abroad every year. The successful development of this machine tool has broken the technological blockade of the West and provided strong technical and equipment support for the development of China's national defense industry

Domestic CNC machine tools are exported to developed countries

Dalian Guangyang pioneers

In July 2013, the high-precision five axis vertical machine tool with independent intellectual property rights of Dalian Guangyang Technology Engineering Co., Ltd. was exported to Germany for the first time. Since then, the German company has purchased three high-end CNC machine tools from Dalian Guangyang again.

This is the first time that Chinese enterprises sell CNC machine tools to western developed countries, which marks that China's high-end five axis CNC machine tools have broken foreign monopoly and technical barriers.

At present, the localization of China's medium and high-end machine tools has reached more than 70%, and even the five axis CNC machine tools have been successfully exported to Germany, which indicates that we will no longer be subject to other countries in the field of precision machining.

Today, China has not only become the world's largest machine tool producer and consumer, but also the world's largest machine tool exporter.

In the early days after the founding of the people's Republic of China, China's heavy industry was still blank, not to mention the ability to independently produce machine tools, which led to the long-term dependence on the purchase and imitation of weapons. In order to reverse this passive situation, China has listed the development of machine tool industry as a key project since the founding of the people's Republic of China.

However, the multi axis linkage machine tool technology has been kept secret by western countries. Therefore, for many years, we have been stuck in the neck of developed countries. Not only is the procurement channel blocked, but also we must accept the harsh conditions of "end-user access" by foreign manufacturers. Foreign parties can obtain information on the end use and use of CNC machine tools, which is very easy to cause leakage.

With the rapid development of China's machine tools in recent years, China has become the bulldozer of the original pattern of the world's machine tool industry, pushing Germany, Japan and other traditional machine tool powers into the top corner of the high-end and specialized direction.

Of course, there is still a big gap between China and foreign countries in the field of machine tools. Most of the functional components depend on foreign countries, which is mainly related to our late start in related technologies. However, even so, the gap between us is narrowing.

I believe that China's machine tool industry will one day stand on the top of the world like aerospace engineering and infrastructure engineering, and rise to a high level in the world!
