When it comes to aerospace industry, most people may think that it is such a great tasks for human beings to finish. However, have you ever thought the reason that why those airplanes or aircrafts could be safe in the universe? In this article, we will let you know the answer. That is, the CNC machining.
1. Why we use CNC technology in aerospace industry?
2. What is Aerospace CNC Machining?
3. Aerospace CNC machining materials
4. Ways of aerospace machining
The aerospace industry includes various types of air traffic, from large Boeing 747 jets carrying hundreds of passengers to spacecraft rockets designed to explore the International Space Station, the Moon and even Mars. The spacecraft is designed to stay in outer space for months or even years. Given this long-term maintenance, they must be developed with incredible accuracy and accuracy. In this case, computer numerical control (CNC) is more and more suitable for this field.
Aerospace NC machining is used to manufacture parts for assembly and maintenance of aircraft and space shuttle. In aerospace industry, aircraft usually needs NC processing parts, sets and components. Aerospace equipment and aircraft components require the best components to make hinges, bushings, valves, fixtures or other customized components of the highest quality metal. Titanium and Kovar alloys are most commonly used in aerospace components, but other components include stainless steel, chromium-nickel-iron alloys, aluminum, brass, bronze, ceramics, copper and other specific types of plastics.
A key part of aerospace engineering is material choice. Aerospace manufacturing requires materials of superior strength, reliability, and resistance to wear to ensure they are ready for changing conditions and demanding structural loads. Here are some materials that needed in aerospace machining:
Stainless steel is a viable alloy material for multiple aerospace components and has been used in aerospace applications for decades.Stainless steel
Stainless steels are resistant to corrosion and high temperature oxidation, due to their chromium content, which produces a rich oxide film. Common aerospace applications for stainless steel include fuel tanks, exhaust components, aircraft panels, high temperature engine parts, and parts requiring welding.
Aluminum has always been the main material in aerospace industry. This metal is almost a third of the weight of stainless steel, helps improve fuel efficiency and weight margin, and is usually cheaper and easier to operate. However, it is also a more efficient thermal conductor, so it is not suitable for parts requiring higher heat resistance and more difficult to weld. With the development of technology, other alloys (and composites) may replace aluminium as the main aerospace materials, but it still has applications in today's industry.
Now the aerospace industry is the leader in the use of titanium alloys, because the ratio of strength to weight of titanium is amazing. This metal is an attractive choice for aerospace engineering because it is lighter than aluminium but has impressive heat and corrosion resistance. When treated with carbon fiber reinforced polymer (CFRPS), its excellent resistance will appear. From frameworks to engines, manufacturers see titanium as an ideal solution for complex aerospace processes.
The characteristics of those super alloys, metal alloys are high heat and corrosion resistance, lightweight structure and superior strength. A super alloy is often the best choice for a jet engine’s hottest sections, the turbine and compressor stages. Some of the super alloys we have worked with are nickel super alloys, cobalt super alloys and iron super alloys.
Through three-dimensional numerical control processing, almost any model or technical drawings can form strict specifications. 3D machining is especially suitable for large aerospace components. 3D technology and technology can handle complex operations easily, accurately and cheaply.
Five-axis CNC processing uses high precision CNC to operate a machine tool, which can move cutters or parts on five axes at the same time. This extremely precise method is the ideal choice for aerospace engineering, which involves the use of specialized materials to make particularly complex parts.
Capability Maturity Model (CMM) inspection service ensures that your aerospace component CAD model and two-dimensional drawings are fully realizable in terms of quality, reliability and security. CMM inspection is an important step in all Aerospace Engineering projects, in which safety is very important.
By converting component geometry into CMM programmable data, each complete component will be examined by detailed reports.
CNC turning enables the manufacturing of multiple parts to interact perfectly. Computer Aided Drawing (CAD) software controls a CNC lathe, which can cut redundant materials and rotate materials at high speed. The accuracy of this machine is less than 10 microns. According to the design drawings, ensure that the CNC lathe works in accordance with accurate specifications, so that aerospace components have the highest quality and reliability.
In this article, we brief introduce the application of CNC machining in the area of aerospace industry from some aspects: why we use CNC technology in aerospace industry, what is Aerospace CNC Machining, aerospace CNC machining materials and ways of aerospace machining. Although the content we include may not be sufficient enough, we still hope that you can learn something from our effort. If you have any technical inquiries, please contact us directly.
