First, the precision CNC system needs to help the development of aerospace
Aerospace industry product parts are characterized by high temperature resistance, high strength and difficult processing. At the same time, there are many alloy materials and composite materials, many complicated structural parts and high process requirements. This puts higher requirements on its processing equipment. In order to promote the development of aerospace industry, in recent years, powerful machine tool manufacturers have begun to develop and manufacture high-end CNC machine tools to replace imports and contribute to the national cause.
The demand for numerical control technology and equipment for aerospace product manufacturing presents the following six characteristics: high numerical control rate requirements for machining, almost all types of CNC machine tools are required; high requirements for CNC machine tool utilization and CNC machining efficiency; CNC machining It has become the CAD/CAPP/CAM integrated application and the basis of no drawing manufacturing; high-speed and high-precision CNC cutting has become an inevitable trend; it is required to optimize the CNC machining process and cutting parameters of different materials and structures; some CNC technology and Equipment is specific. There is a large demand for CNC vertical lathes and vertical turning centers, vertical milling machining centers, vertical and horizontal conversion machining centers, CNC boring and milling machines, high-efficiency special blade machining centers, dental profile grinding machines, and CNC EDM machines. It is used for the processing of structural parts such as integral casings with integral materials, integral impellers and leaf discs, and various complex profile blades. In the engine manufacturing of aerospace products, the processing of thrust indoor and outdoor wall structures, valves, valves, rotor blades, etc., has more demand for CNC milling machines/milling centers, precision CNC lathes, CNC boring and milling machines and other numerical control equipment.
Airborne equipment has many key components, small size, complex structure and high precision. For precision CNC boring and milling machines and machining centers, precision CNC lathes and turning centers, precision CNC universal cylindrical grinding machines, CNC EDM machines and wire cutting machines There are important requirements for CNC equipment to meet the precision and ultra-precision machining requirements of various housings, valve bodies, hydraulic couplers, hydraulic flat valves, light pipes, laser gyro mirrors, aspherical optical parts and other components. The projectile/arrow/starborne equipment of aerospace products mainly consists of high-precision precision instruments and machinery such as control, guidance and detection components. The requirements for numerical control technology and equipment are: precision CNC lathes and turning centers, high-precision universal CNC grinding machines. , CNC optical coordinate grinding machine and forming grinder, high-precision CNC EDM machine tools.
Aerospace industry product parts are characterized by high temperature resistance, high strength and difficult processing. At the same time, there are many alloy materials and composite materials, many complicated structural parts and high process requirements. Aircraft fuselage structural parts mainly include beams, frames, ribs, siding and other parts. Most of these parts are made of aluminum alloy or titanium alloy. The general outline size is large. It is a thin-walled multi-cavity integral frame structure, mechanical cutting. The amount of removal is large and the surface quality is high. The processing of such parts requires large and heavy-duty machine tools, and requires a high-rigidity machine with a load of more than 10 tons and an effective stroke of more than 15 meters. The aero engine is the heavy weapon of the country and is the cutting edge of the equipment manufacturing industry.
Due to its high development difficulty, high technical content and high industrial returns, the aero engine is known as the modern industry; the jewel in the crown. To achieve breakthroughs in this field as soon as possible is of great significance for strengthening China's economic and national defense capabilities and enhancing overall national strength. The country has proposed the goal of 80% localization of machine tools in the aerospace industry by 2020. This is not only a hope, but also a hope for the rise of big countries. It requires concerted efforts from the entire industry including CNC systems, functional components and mainframe enterprises. . In this regard, machine tool enterprises still need to work hard, and technological breakthroughs still need to be vigorous.
