Application Prospect of Abrasives in Military Industry

Characteristics of China's Military Industry In 2013, China’s defense budget increased by 10.7% over the previous year, and maintained a rate of more than 10% year-on-year for three consecutive years. The defense budget for the first time clearly stated: “Promoting the scientific development of national defense and army building and accelerating the transformation of the combat force generation model. Needs, and appropriate increase in the use of high-tech weaponry and its supporting facilities, the use of the direction, since 2011, a number of batches of advanced weapons and equipment have been continuously exposed, highlighting the confidence of China's defense industry construction. The successful test flights of 歼20 and 歼31, the successful launch of the manned spacecraft and the Chang’e-1, and the successful navigation of China’s first aircraft carrier all showed that China’s defense industry will no longer be obsessed with advancing. Instead, it will show its muscles to the world with great strides.

Although, as early as in 2008, China’s national defense white paper, it clearly stated that it supports the overall listing of military-industrial enterprises and promotes the rapid development of military enterprises. However, in fact, until 2012, China’s Interim Measures for Implementation of Joint-stock System Reform of Military Enterprises was announced. After the measures were announced, the restructuring and restructuring of military-industrial enterprises was rapidly put on the agenda. More and more capital entered the military-industrial enterprise and was used by military-industrial enterprises. Development has brought about a period of rapid development.

At the same time, the development of the military industry is not always positively related to the macro economy. The political and military pattern is the main factor that affects the development of the military industry. Since 2011, with the increasingly tense international situation, the problems in the East China Sea and the South China Sea have become increasingly prominent. As a result, the military sector has maintained an upward stance when the overall economy continues to slump. However, the country’s defense budget has doubled, and it has surpassed. GDP growth over the same period.

National defense building direction <br> <br> April 16 this year, the State Council Information Office published a report entitled "China to diversify the use of armed forces" of the "2013 Defense White Paper", the second part of "the armed forces building and "Development" has pointed out to us the direction of development of China's military industry in the coming period:

The Air Force clearly required that: "Develop advanced combat equipment such as new-generation combat aircraft, new surface-to-air missiles, and new types of radar, improve the early warning, command, and communications networks, improve strategic warning, deterrence, and long-range air strike capabilities." It highlights the key points of China’s aircraft carrier construction and also shows that China’s determination to improve the capabilities of offshore long-range maneuvering operations, cooperation in the offshore area, and responding to non-traditional security threats, and enhancing strategic deterrence and counterattack capabilities. The Army’s emphasis on information-based operations and long-range assault capabilities. The first disclosure of the Second Artillery Corps not only clarified its mission of “containing the use of nuclear weapons against other countries and carrying out nuclear counterattacks” but also indicated that China will have further actions in the nuclear industry.

The white paper clearly stated that the Chinese armed forces "resolutely safeguard the country's core interests." Historical experience tells us that there is no strong military force and the maintenance of national core interests is nothing more than empty talk. When the international situation becomes increasingly tense, when small countries around the country continue to provoke, only the display of one's own muscles can ensure the country’s core interests. Stealth fighters, aircraft carrier fighter aircraft, heavy military transport aircraft, aircraft carriers show that the development of China's military equipment from land to sea and air development trend, and the application of the "Beidou" navigation system, it shows that China's military industry is gradually dual-use military and civilian The direction of development.

Military-industrial complex requires high abrasive grinding tools, precision, sharp <br> <br> extensive use of abrasives in the military industry, focused on all aspects of shipbuilding, aerospace, military equipment manufacturing, equipment manufacturing and manufacturing of weapons, the The scope of application is not only broad, but also has a high technological content and high precision requirements. This determines the use of abrasives in the military industry and must be elevated, refined, and sharp.

Abrasives <br> <br> in the use of aerospace equipment is following the United States, Britain, Russia, France, the fifth country capable of independently developed aircraft engines. The engine is undoubtedly the source of the "heart" and power of aerospace equipment. Aero-engine manufacturing is inseparable from abrasives and grinding. For example, in grinding, the matching surfaces, sealing surfaces, and nozzle working surfaces of various aeroengine valves require high luminosity, shape, and dimensional accuracy, and all require grinding to meet the requirements.

Aeroengines require good thermal and thermal stability and excellent high temperature mechanical properties. The continuous upgrading of aviation products, especially with the widespread use of various composite materials and difficult-to-machine materials, is gradually improving its processing technology. Currently, more and more advanced grinding tools and technologies such as PCD and PCBN tools and strong grinding are used in the aviation field. In particular, PCD tools have been consistently approved and widely used with superior cutting performance, durability, and high toughness. For example, the PCD tool for machining engine pistons, the PCD file for machining the piston pin hole of the engine, and the electroplated CBN grinding wheel for machining narrow and deep grooves at the root of the aeroengine turbine blade. The ceramic binder CBN grinding wheel is also used in processing aero engines.

Abrasive Abrasives in Satellite and Its Application Industries <br><br><br><br> Electroplated Abrasive Abrasive Wheels in Grinding Radomes in Complex Surfaces Have a Good Effect. Ball screws are used in satellites, missile guidance systems, and space capsule space transmissions. Ball screw manufacturing requires a CNC screw grinder. High-speed grinding is an effective way to improve grinding accuracy and grinding surface quality, while significantly improving production efficiency. NSK displayed ball screws and rolling guides at speeds up to 240m/min at the Hanover EMO in 2005. Domestic ball screw speeds up to 100m/minLR, there is still a big gap. CNC screw grinders are now using CBN grinding wheels. Enterprises that manufacture these two kinds of super-hard material products should be pioneering and improve the level of research and development, and make due contributions to “proactively promote the construction of space infrastructure and promote the development of satellites and their application industries.”

At present, the speed of replacement of military equipment in China is accelerating. In the next few years, high-end CNC machine tools and basic manufacturing equipment will play an increasingly important role in military-industrial enterprises.

Although China's abrasive abrasive industry has a history of several decades, most of China's abrasive abrasive products are dominated by medium and low-end products. However, the military industry has very strict requirements on abrasives. If abrasives companies want to occupy a place in the military industry, they must change their production methods, increase their investment in science and technology, increase the technological content of their products, and adhere to the high-end development direction of their products. Only in this way can we seize a new round of high grounds for economic and technological development and provide more effective services and guarantees for the development of military-industrial enterprises, thus stimulating the development of enterprises and the revitalization of the entire abrasives industry.
