CNC parts are used in the aerospace industry
In the field of aerospace of nowadays society, the manufacture of precision parts is very important. CNC machining technology has become one of the key processes for manufacturing these parts. We will describe the application of CNC machining in the aerospace field and how it enables the 'engraving' process of manufacturing precision parts.
First, let's look at CNC machining. CNC is short for computer numerical control, and CNC machine tools are the main equipment for CNC processing. These machines use pre-programmed instructions to control the movement of tools and workpieces, enabling high-precision machining processes. Compared with traditional machining methods, CNC machining has a higher degree of automation and greater accuracy, and is suitable for manufacturing parts with complex shapes and high precision requirements.
In the aerospace field, the accuracy of parts is very high, because they directly affect the performance and safety of the aircraft. CNC machining technology can meet these requirements. First, the engineer converts the designed CAD file into a CNC program to define the machining path and machining parameters of the part. These programs are then loaded onto the CNC machine through a CNC control system. In the process of processing, the CNC machine tool will automatically execute the instructions to achieve the 'engraving' of the tool on the workpiece. Due to the high precision and stability of CNC machining, it is possible to ensure that the size and shape of the parts are exactly as designed.
In addition to high precision, CNC machining is also highly efficient. A CNC machine can process multiple parts at the same time, and the same machining process can be repeated at different points in time. This makes mass production of the same parts much easier and more efficient. In aerospace, this means that large numbers of precision parts can be produced more quickly, speeding up the entire manufacturing process.
CNC machining technology plays an important role in the aerospace field. Through CNC machining, it is possible to achieve efficient and high-precision 'engraving' of precision aerospace parts. This not only improves manufacturing efficiency, but also ensures the quality and accuracy of parts, which has a positive impact on the development of the aerospace industry
Why do we use CNC technology in the aerospace industry?
The aerospace industry includes all 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 increasingly suitable for this field.
What is aerospace CNC Machining?
Aerospace CNC machining is used to manufacture assembly and maintenance parts for aircraft and space shuttles. In the aerospace industry, aircraft often require CNC machining of parts, sets and assemblies. Aerospace equipment and aircraft parts require the best parts to make hinges, bushings, valves, fixtures or other custom parts in the highest quality metal. Titanium and Corvar alloys are most commonly used in aerospace components, but other components include stainless steel, inconel, aluminum, brass, bronze, ceramics, copper, and other specific types of plastics.
Aerospace CNC machining materials:
A key part of aerospace engineering is material selection. Aerospace manufacturing requires materials with superior strength, reliability and wear resistance to ensure they are ready for changing conditions and demanding structural loads. Here are some of the materials needed for aerospace processing:
Stainless steel is a viable alloying material for a variety of aerospace components and has been used in aerospace applications for decades.
Stainless steels are resistant to corrosion and high temperature oxidation because their chromium content produces a rich oxide film. Common aerospace applications of stainless steel include fuel tanks, exhaust parts, aircraft panels, high-temperature engine parts, and parts that require welding.
Aluminum has always been a staple of the aerospace industry. This metal is almost a third of the weight of stainless steel, helps improve fuel efficiency and weight margin, and is generally cheaper and easier to handle. 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. As technology evolves, other alloys (and composites) may replace aluminum as the primary aerospace material, but it still has applications in industry today.
Now the aerospace industry is leading the way in using titanium alloys because of the amazing strength-to-weight ratio of titanium. This metal is an attractive choice for aerospace engineering because it is lighter than aluminum but has impressive heat and corrosion resistance. When treated with carbon fiber reinforced polymers (CFRPS), their excellent resistance appears. From frames to engines, manufacturers see titanium as the ideal solution for complex aerospace processes.
These super alloys, metal alloys, are characterized by heat and corrosion resistance, lightweight structure, and high strength. Superalloys are often the best choice for the hottest parts of jet engines, turbine and compressor stages. Some of the superalloys we use are nickel superalloys, cobalt superalloys and iron superalloys.
Aerospace processing methods
★ 3D processing
By 3D CNC machining, almost any model or technical drawing can be formed into a strict specification. 3D machining is particularly suitable for large aerospace components. 3D technology and techniques can handle complex operations easily, accurately, and inexpensively.
★ 5-axis machining
Five-axis CNC machining uses a high-precision CNC operated machine to move a tool or part on five axes simultaneously. This extremely precise method is ideal for aerospace engineering, which involves the manufacture of particularly complex parts using special materials.
★ Coordinate detection
Capability Maturity Model (CMM) inspection services ensure that your CAD models and 2D drawings for aerospace components are fully achievable in terms of quality, reliability and safety. Coordinate inspection is an important step in all aerospace engineering projects, where safety is very important.
By converting the component geometry into CMM programmable data, each complete component is inspected with detailed reports.
★CNC Turning
CNC turning enables the manufacturing of multiple parts to interact perfectly. Computer-aided drafting (CAD) software controls CNC lathes that can cut excess and rotate materials at high speeds. The accuracy of this machine is less than 10 microns. According to the design drawings, ensure that the CNC lathe works according to the exact specifications, so that the aviation parts have the highest quality and reliability
