The success or failure of aerospace operations depends on the accuracy, precision and quality of the components used. For this reason, aerospace companies utilize advanced manufacturing techniques and processes to ensure that their components fully meet their needs. While new manufacturing methods such as 3D printing are rapidly gaining popularity in the industry, traditional manufacturing methods such as machining continue to play a key role in the production of parts and products for aerospace applications. Such as better CAM programs, application-specific machine tools, enhanced materials and coatings, and improved chip control and vibration damping - have significantly changed the way aerospace companies manufacture critical aerospace components. However, sophisticated equipment alone is not enough. Manufacturers must have the expertise to overcome the material processing challenges of the aerospace industry.
Material requirements
The manufacture of aerospace parts first requires specific material requirements. These parts typically require high strength, low density, high thermal stability and corrosion resistance to handle extreme operating conditions.
Common aerospace materials include:
1. High strength aluminum alloy
High-strength aluminum alloys are ideal for aircraft structural parts because of their light weight, corrosion resistance and ease of processing. For example, 7075 aluminum alloy is widely used in the manufacture of aerospace parts.
2. titanium alloy
Titanium alloys have excellent strength to weight ratio and are widely used in aircraft engine parts, fuselage components and screws.
3. Superalloy
Superalloys maintain strength and stability at high temperatures and are suitable for engine nozzles, turbine blades and other high-temperature parts.
4. Composite material
Carbon fiber composites perform well in reducing structural weight, increasing strength and reducing corrosion, and are commonly used in the manufacture of casings for aerospace parts and spacecraft components.
What are the process characteristics of aerospace parts processing?
Process planning and design
Process planning and design are required before processing. At this stage, it is necessary to determine the overall processing scheme according to the design requirements of the parts and material characteristics. This includes determining the process of processing, the choice of machine tool equipment, the selection of tools, etc. At the same time, it is necessary to carry out detailed process design, including the determination of cutting profile, cutting depth, cutting speed and other parameters.
Material preparation and cutting process
In the process of aerospace parts processing, the first need to prepare working materials. Usually, the materials used in aviation parts include high-strength alloy steel, stainless steel, aluminum alloy and so on. After the material preparation is completed, the cutting process is entered.
This step involves the selection of machine tools, such as CNC machine tools, lathes, milling machines, etc., as well as the selection of cutting tools. The cutting process needs to strictly control the feed speed, cutting speed, cutting depth and other parameters of the tool to ensure the dimensional accuracy and surface quality of the parts.
Precision machining process
Aerospace components are usually very demanding in terms of size and surface quality, so precision machining is an indispensable step. At this stage, it may be necessary to use high-precision processes such as grinding and EDM. The goal of the precision machining process is to further improve the dimensional accuracy and surface finish of the parts, ensuring their reliability and stability in the aviation field.
Heat treatment
Some aerospace parts may require heat treatment after precision machining. The heat treatment process can improve the hardness, strength and corrosion resistance of the parts. This includes heat treatment methods such as quenching and tempering, which are selected according to the specific requirements of the parts.
Surface coating
In order to improve the wear resistance and corrosion resistance of aviation parts, surface coating is usually required. Coating materials can include cemented carbide, ceramic coating, etc. Surface coatings can not only improve the performance of parts, but also extend their service life.
Assembly and testing
Do parts assembly and inspection. At this stage, the parts need to be assembled in accordance with the design requirements to ensure the accuracy of the match between the various parts. At the same time, rigorous testing is required, including dimensional testing, surface quality testing, material composition testing, etc., to ensure that parts meet aviation industry standards.
Process characteristics
Strict quality control: The quality control requirements of aviation parts are very strict, and strict testing and control are required at each processing stage of aviation parts to ensure that the quality of parts meets the standards.
High precision requirements: Aerospace components typically require very high accuracy, including dimensional accuracy, shape accuracy and surface quality. Therefore, high-precision machine tools and tools need to be used in the processing process to ensure that the parts meet the design requirements.
Complex structure design: Aviation parts often have complex structures, and it is necessary to use multi-axis CNC machine tools and other equipment to meet the processing needs of complex structures.
High temperature resistance and high strength: aviation parts usually work in harsh environments such as high temperature and high pressure, so it is necessary to choose high temperature resistance and high strength materials, and carry out the corresponding heat treatment process.
Overall, aerospace parts processing is a highly technology-intensive, precision demanding process that requires strict operating processes and advanced processing equipment to ensure that the quality and performance of the final parts can meet the stringent requirements of the aviation sector.
Processing difficulties

Super alloy processing
The processing of superalloys is difficult and requires special tools and processes to handle these hard materials.
Large parts
The parts of the spacecraft are usually very large, requiring large CNC machine tools and special processing equipment.
Quality control
The aerospace industry is extremely demanding on part quality and requires rigorous quality control and inspection to ensure that every part meets the standards.
In aerospace parts processing, precision and reliability are key. A deep understanding and fine control of materials, processes, precision and machining difficulties is the key to manufacturing high-quality aerospace parts.
Brand of moisture meter: Boshi Model: bos-180a series Test item: automotive plastic sheet
The water content of plastics is a key reason affecting the production process, commodity appearance and commodity characteristics of resin materials such as polyethylene (PE) and polypropylene (PP). In the injection molding process, if the plastic raw materials with excessive water content are used for production and manufacturing, it will cause some production and processing problems and affect the product quality, such as cracking of the surface layer, reflection, wear resistance, reduction of material mechanical properties such as service performance and tensile strength, etc. Therefore, the control of water content is particularly important for the production of high-quality plastic products.
Testing water content is a necessary step in the production of plastic materials. Testing moisture content is basically divided into national standard method and rapid moisture tester method. Boshi plastic rapid moisture tester is a widely used instrument and equipment at present.(auto plastic parts)Test steps:
1. First, take out the moisture meter, place it and power it on, then break the test material into small pieces, pour out about 6 grams of plastic pieces and pour them into the stainless steel tray. In order to dry and dry the plastic thoroughly during the test, we spread the fine pieces of plastic parts into a scattered form so that the temperature can penetrate into the plastic parts. Use tweezers to lay small pieces of plastic parts evenly. In order to avoid the zoom and blackening of small pieces of plastic parts after baking, we set the temperature at 105 , press the "start" key to start the test for 1 minute and 49 seconds, and then the test ends, and the test data displays 0.3%;
2. In order to obtain more stable data results, wait for the moisture meter of plastic parts to cool down before the second test. When the temperature of the instrument itself drops below 40 , also take about 6 grams of small pieces of plastic parts into the stainless steel tray, and lay the small pieces of plastic parts evenly. This time, we set the temperature at 105 , press the "start" key to start the test, and the test ends after 1 minute and 38 seconds, The test data showed 0.29%;Test data:From the above tests, we found that the moisture of these plastic sheets was well controlled and the moisture distribution was relatively uniform, which promoted the plastic parts to be completely dry after the test, and the moisture data results were also very good.
matters needing attention:1. Small pieces of plastic sheets shall be small enough to ensure the complete drying of water in plastic parts, and shall be evenly spread on the tray as far as possible, rather than simply stacked together.2. Do not set the temperature too high to prevent the plastic parts from melting in case of high temperature. The moisture meter of plastic parts has its use environmental restrictions. Please use it under the environmental conditions specified in the product operation manual. Do not operate in harsh environments.
3. As the instrument is a precision instrument, do not knock the workbench or vibrate the instrument during heating, otherwise the measurement will be inaccurate.4. After the test, do not touch the tray for the Yi first time to avoid scalding.Editing: JQ
The requirements of lightweight, safety and decoration in modern automobile manufacturing industry drive the development of traditional welding technology in the field of automobile plastics. In recent years, with the application of a variety of high-end technologies such as ultrasonic, vibration friction and laser technology in the field of automobile plastic parts manufacturing, the technical level and supporting capacity of domestic automobile parts manufacturing industry have been greatly improved.As for the welding and welding process of automotive interior parts, hot plate welding, laser welding, ultrasonic welding, non-standard ultrasonic welding machine, vibration friction machine, etc. have been developed. In the process, one-time overall or complex structure welding can be realized, and the optimal design requirements can be achieved on the basis of simplifying mold design and reducing molding cost.For typical interior and exterior trim parts, large components with high surface quality and complex structure, such as instrument panel, door panel, column, glove box, engine intake manifold, front and rear bumper, must select corresponding welding technology, and adopt appropriate welding process according to the requirements of interior structure, performance, materials and production cost. All these applications can not only complete the corresponding manufacturing process, but also ensure the excellent quality and perfect shape of products.
Hot plate welding machine: the hot plate welding machine equipment can control the horizontal or vertical movement of the hot plate welding die, and the transmission system is driven by pneumatic, hydraulic drive or servo motor. The advantages of hot plate welding technology are that it can be applied to workpieces of different sizes without area limitation, applicable to any welding surface, allowing plastic allowance compensation, ensuring welding strength, and adjusting welding procedures according to the needs of various materials (such as adjusting welding temperature, welding time, cooling time, input air pressure, welding temperature and switching time, etc.), In the welding process, the equipment can maintain good stability, ensure consistent welding effect and accuracy of workpiece height after machining.
Another feature of the horizontal hot plate welding machine is that it can rotate at 90 for cleaning. The processing period of hot plate welding machine can generally be divided into: original position (the hot plate does not move with the upper and lower molds), heating period (the hot plate moves between the upper and lower molds, and the heat of the hot plate moves down the upper and lower molds to dissolve the welding surfaces of the upper and lower workpieces), transfer period (the upper and lower molds return to the original position, and the hot plate exits), welding and cooling period (the upper and lower dies are joined to make the workpiece welded at the same time and cooled for forming), and return to the original position (the upper and lower dies are separated, and the welded workpiece can be taken out).
In the early automobile industry, these welding equipment were relatively common, but with the continuous improvement of the requirements for the structure, shape and service life of the parts themselves, the requirements for their processing equipment are higher and higher. Moreover, because the size of the equipment is limited to the size of the welded parts, the equipment and equipment driving mode should be selected according to the size of the parts in the design. The most important thing is the parts The heating area is large and there is large deformation. In addition, the welding process distinguishes the polarity and non polarity of welding plastics, resulting in the gradual replacement of hot plate welding by ultrasonic welding and laser welding. The main parts used for welding in China include automotive plastic fuel tank, battery, tail lamp, glove box, etc.
Laser welding: laser welding technology is widely used in today's medical device manufacturing industry. Only a few manufacturers in the automotive industry use laser welding air inlet pipe, etc. because it is a new welding technology, it is not very mature to a certain extent, but it is believed that it will be widely used in the near future because of its remarkable welding characteristics. Its advantage is that it can weld TPE / TP Or TPE products; under the condition of no vibration, nylon, workpiece with sensitive electronic parts and three-dimensional welding surface can be welded, which can save cost and reduce waste products.
In the welding process, the resin melts less, the surface can be welded tightly, and there is no flash or glue overflow. It is allowed that rigid plastic parts can be welded without glue overflow and vibration. Generally, workpieces with soft or irregular welding surfaces can be welded evenly regardless of the size of workpieces, especially for large-scale production of high-tech micro parts. However, laser conduction is limited. "Quasi synchronous" laser welding technology uses a scanning mirror to transmit the laser beam to the welding surface at the speed of 10m / s according to the welding shape. It can walk on the welding surface as many as 40 times in 1s. The plastic around the welding surface melts and the two workpieces are welded after pressurization.
Laser welding can be roughly divided into: solid Nd-YAG system (laser beam is generated by crystal) and diodesystem (high power diode laser) , CAD data programming. All materials can be laser welded with body materials, among which acrylonitrile butadiene styrene is most suitable for laser welding with other materials, nylon, polypropylene and polyethylene can only be welded with their own body materials, and other materials have general applicability for laser welding.fqj
