The aerospace field represents the highest quality and standard of the entire industrial system. The aerospace industry places extremely high demands on processing materials and machining accuracy. We are committed to providing aerospace manufacturers with precision and efficient cutting tool solutions.
The aerospace field has the following specific requirements for tool quality and performance:
1. High strength and hardness: able to withstand extreme mechanical environments such as aerodynamic pressure, vibration and shock in high-speed flight.
2. High-temperature resistance: maintain stable physical and chemical properties in high-temperature environments without deformation or performance degradation.
3. High precision: Machining precision is required to ensure that the dimensions and shapes of parts are accurate to the micron or even nanometer level.
4. Low weight: Reducing the overall weight of the vehicle contributes to improved fuel efficiency and flight performance.
5. Corrosion resistance: resistant to a wide range of chemicals, including fuels, lubricants and corrosive components of the atmosphere.
6. Good abrasion resistance: stays sharp and durable over long periods of use, reducing frequent replacement and maintenance.
7. Reliability and stability: Maintain stable performance under complex working conditions and avoid malfunction or failure.
8. Fatigue resistance: able to withstand many repetitions of loads and stresses, not easy to produce fatigue cracks.
9. Good cutting performance: capable of efficiently cutting and machining a variety of special materials, such as titanium alloys, high-temperature alloys and so on.
10. Good thermal conductivity: Helps dissipate heat and prevents localized overheating that can lead to damage to tools or parts.
Quality testing of tools in aerospace typically includes the following:
1. Material analysis: Through chemical analysis, spectral analysis and other methods, the composition and purity of tool materials are determined to ensure compliance with the high standard requirements of aerospace and aviation.
2. Dimensional and geometric accuracy testing: Use high-precision gauges, such as coordinate measuring machines and laser interferometers, to accurately measure the dimensions, shape and positional accuracy of the tools to ensure compliance with design specifications.
3. Hardness test: A hardness tester is used to test the hardness of the tool to assess its wear resistance and resistance to deformation.
4. Metallographic organization check: Observe the metallographic organization of the tool material through a microscope to check for the presence of defects, inclusions, grain size and distribution.
5. Fatigue test: Simulate the repetitive loading conditions of the tool in actual use and conduct fatigue test to check its fatigue resistance.
6. Corrosion resistance test: Place the tool in a specific corrosive environment and observe its ability to resist corrosion.
7. Non-destructive testing: such as ultrasonic testing, magnetic particle testing, penetration testing, etc., is used to detect the presence of cracks, pores and other defects within the tool without destroying the tool itself.
8. High-temperature performance testing: performance testing of tools in a high-temperature environment, including hardness, strength, coefficient of thermal expansion and other indicators of detection.
9. Cutting performance testing: Evaluate the cutting efficiency, surface quality and tool life of tools through actual cutting experiments.
10. Vibration and shock testing: Simulation of in-flight vibration and shock conditions to test the stability and reliability of tools in such environments. The combination of these quality inspection methods ensures that the tools used in aerospace are of high quality and performance, meeting the stringent requirements of extreme environments.
