1. Precision CNC systems need to help the development of aerospace
The parts of aerospace industry products are characterized by high temperature resistance, high strength, and difficult to process. At the same time, there are many alloy materials and composite materials, many complex structural parts, and high process requirements.This puts forward higher requirements for its processing equipment. In order to promote the development of the 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 CNC technology and equipment in the manufacture of aerospace products presents the following six characteristics: the CNC rate of machining is high, and there is a demand for almost all kinds of CNC machine tools; the utilization rate of CNC machine tools and the efficiency of CNC processing are high; CNC machining has become the basis for CAD/CAPP/CAM integrated application and non-drawing manufacturing; high-speed and high-precision CNC machining has become an inevitable trend; it is required to optimize the CNC machining technology and cutting parameters of parts of different materials and structures; some CNC technologies and equipment are specialized.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, tenon and tooth forming grinding machines, CNC electric discharge machining machine tools, etc., mainly used for the use of difficult-to-process materials, complex structure of the overall chassis, the overall impeller and blade plate and other structural parts and various complex profile blade processing.In the engine manufacturing of aerospace products, there is more demand for CNC milling machines/milling centers, precision CNC lathes, CNC boring and milling machines and other CNC equipment for the processing of thrust indoor and outdoor wall structures, valves, valves, rotor blades, etc.
There are many types of key components, small sizes, complex structures and high precision of aviation airborne equipment. There are important requirements for CNC equipment such as precision CNC boring and milling machines and machining centers, precision CNC lathes and turning centers, precision CNC universal cylindrical grinders, CNC electric spark machine tools and wire cutting machine tools to meet the precision and ultra-precision machining requirements of various housings, valve bodies, hydraulic couplings, hydraulic flat valves, optical tubes, laser gyroscope mirrors, aspheric optical parts and other parts.The bullet/arrow/on-board equipment of aerospace products is mainly high-precision precision instruments and machinery such as control, guidance, and detection components. The requirements for CNC technology and equipment are mainly: precision CNC lathes and turning centers, high-precision universal CNC grinding machines, CNC optical coordinate grinding machines and forming grinding machines, high-precision CNC EDM machine tools, etc.
The parts of aerospace industry products are characterized by high temperature resistance, high strength, and difficult to process. At the same time, there are many alloy materials and composite materials, many complex structural parts, and high process requirements.The structural parts of the aircraft fuselage mainly include beams, frames, ribs, siding and other parts. Most of these parts are made of aluminum alloy or titanium alloy. The general outline and dimensions are very large. It is a thin-walled and multi-cavity overall frame structure with a large amount of mechanical cutting and removal, and high surface quality requirements.Processing such parts requires large-scale and heavy-duty machine tool equipment, which requires a high-rigidity machine tool with a workbench bearing more than 10 tons and an effective stroke of more than 15 meters.Aviation engines are the heavy weapons of the country and the cutting-edge of equipment manufacturing.
Due to the high difficulty of development, high technical content and high industrial return, aero engines are known as the jewel in the crown of modern industrial engines.Achieving breakthroughs in this field as soon as possible is of great significance for enhancing our country's economic and national defense strength and enhancing its comprehensive national strength.The country has put forward the goal of reaching 80% of the localization rate of machine tools in the aerospace field by 2020. This has not only become an expectation, but also a hope for the rise of a large country. It requires the concerted efforts of the entire industry, including CNC systems, functional components, and host companies.In this regard, machine tool companies still need to work hard, and technological breakthroughs still need to work hard.
