An aircraft is mainly composed of 3-5 million parts, which require thousands of aircraft parts manufacturers to produce. aircraft parts mainly include the body, engine, airborne equipment (including avionics equipment and electromechanical equipment), interior decoration, and other five parts.
The aerospace industry requires high quality and industry standards. The special nature of aircraft applications also makes it need to produce high-quality parts. Aircraft parts manufacturers should focus on safety and risk management and be ready to meet aerospace customers' requirements. The aircraft parts and assembly are always manufactured by CNC machining. The advantages of CNC machining make it very important for the aerospace industry.
The types and characteristics of CNC machining aircraft parts
1. High performance: using new difficult-to-machine materials such as titanium.
2. Lightweight: extensive application of thin-walled structures.
3. Accuracy: Continuously improve processing accuracy
4. High efficiency: Need for higher speed and efficiency.
5. Reliability and economy: increasingly stringent quality and cost controls
aircraft parts manufacturing requires materials with exceptional strength, reliability, and wear resistance to ensure they are ready for changing conditions and demanding structural loads.
The materials usually supplied by aircraft parts manufacturers are as follows:
1. Stainless steel
Stainless steel is a suitable material for a variety of aerospace components and has been used in the aerospace industry for many years. Stainless steels with very good characteristics of resistance to corrosion and high-temperature oxidation. Common aerospace applications for stainless steel such as fuel tanks, gears, undercarriages, aircraft panels, high-temperature engine components, and components requiring welding.
2. Aluminum and Aluminum alloy
Aluminum has always been a staple material in the aerospace industry. The metal is almost one-third the weight of stainless steel, helping improve fuel efficiency and weight, and is generally cheaper and easier to operate. But it is also a more efficient heat conductor, so it is not suitable for parts that require higher heat resistance and are more difficult to weld.
3. Titanium and titanium alloys
Aerospace is the industry that uses the most titanium alloys in the world. Titanium alloy is lighter than aluminum but has good heat and corrosion resistance. Commercial and military aircraft require large amounts of this material for their different components, such as discs, blades, shafts, and casings.
4. High temperature superalloy
These superalloys, metal alloys, are characterized by heat resistance, corrosion resistance, lightweight structure, and high strength. Superalloys are often the best choice for the hottest parts of jet engines, the turbine and compressor stages. Some of the superalloys aircraft parts manufacturers use are nickel superalloys, cobalt superalloys, and iron superalloys.
5. Engineering plastics
Because of the characteristics of being extremely lightweight, excellent resistance to shock and vibration, sealing capabilities, and chemical resistance, some plastic materials may be an alternative to some metal materials used in the aerospace industry. PEEK, Polycarbonate, and Ultem are high-performance polymer materials used in aerospace processing. However, not all plastic materials are suitable for aircraft parts.
Due to the special requirements of the aerospace industry, most aerospace companies require aircraft parts manufacturers to have AS9100 certification. AS9100 is based on ISO 9001, the standard that regulates the industry's most important quality management systems and controls quality and safety. We( Shenzhen DMTC Intelligent Technology CO., Ltd.) obtained the certification of AS9100D many years ago, and we have suppliers a various of aircraft parts for global customer. DMTC can provide precision machining of many materials such as metals, plastics, and composites. Based on the high-level facilities and experienced engineers, we can produce high-quality parts with tight tolerances and intricate designs. Welcome to send inquiries to us!
