In the increasingly competitive automotive industry, the quality of every component directly affects the performance, efficiency, and reliability of the entire vehicle. Among these, the seemingly minor step of removing burrs from the internal parts is actually crucial. Abrasive flow deburring machines have shone brightly in this field, becoming a secret weapon for many automotive component manufacturers to improve quality and efficiency.
Abrasive flow technology has extremely wide applications in automotive manufacturing, with one of the most typical examples being the engine field. For example, the high-pressure common rail of the fuel injection system, the injector body, and the intricate lubrication and coolant passages on the engine block and cylinder head. These components contain numerous intersecting holes and deep bores. If the burrs generated after machining are not removed, they may break off during high-speed engine operation. With the oil circulation, these burrs can act like "metal bullets," scratching precision surfaces such as bearings and cylinder walls, leading to serious engine failure. Abrasive flow technology ensures that the abrasive medium flows through every corner, thoroughly and evenly removing these potential threats, thus guaranteeing the long-term durability of the engine.
Another key application is in the transmission system and new energy vehicle fields. The transmission valve body is a core component of hydraulic control, its interior filled with a complex labyrinth of flow channels. It demands extremely high surface finish and burr-free characteristics; even the slightest imperfection can lead to delayed shifting or malfunction. Abrasive flow deburring perfectly polishes these channels, ensuring precise hydraulic control response. Furthermore, in components such as motor housings and battery cooling plates in electric vehicles, efficient cooling channels are crucial for heat dissipation. Abrasive flow not only deburrs but also polishes the inner walls of these channels, reducing fluid resistance, improving cooling efficiency, and indirectly extending the lifespan of the battery and motor.
Introducing abrasive flow deburring machines into automotive manufacturing is not merely purchasing equipment; it represents an upgrade to the product quality system. It replaces the unstable, inefficient, and potentially damaging manual deburring process, achieving process standardization and automation. This enables automotive component suppliers to produce products that meet or even exceed the stringent standards of OEMs with greater efficiency and lower overall costs, building a solid technological barrier in the fiercely competitive market.
The dual high-pressure fluid polishing process is an advanced surface treatment technology, whose core principle is to usea fluid like high viscosity abrasive medium to achieve micro grinding and polishing through complex channels or innerholes of the workpiece under specific pressure. This process usually uses abrasive media composed of high hardness smallparticles (such as silicon carbide, cubic boron carbide, diamond, etc.) mixed with a viscous carrier, and repeatedly grindsthe surface of the workpiece through squeezing motion, thereby achieving the effect of removing burrs and improving,surface smoothness. The abrasive flow process is not only suitable for complex structures such as inner holes, cross holes,and micro holes, but also for efficient processing of irregularly shaped, curved, and spherical workpieces. It is widely usedin aerospace, automotive manufacturing, energy, medical, and other fields.The main advantages of this process lie in its efficiency and precision. Through the fluidity and adaptive characteristics offluid abrasives, this process can penetrate deep holes, narrow gaps, and complex structures inside the workpiece,achieving uniform and consistent machining effects without causing damage to other parts of the workpiece. For example,in the machining of small module gears, the abrasive flow process can remove burrs in a short period of time, improvesurface smoothness to mirror level, and ensure that the tolerance change is only about 1-2 microns, significantly improv-ing the transmission performance and service life of the parts. In addition, the abrasive flow process is applicable tovarious materials such as metals, ceramics, plastics, etc., and can adjust the abrasive type, particle size, and fluid viscosityaccording to the workpiece requirements to achieve the best processing effect.In terms of environmental protection and economy, the abrasive flow process has significant advantages. Compared withtraditional chemical deburring methods, this process does not require the use of harmful chemicals, reducing environ-mental pollution and harm to human health. At the same time, its high efficiency reduces production costs and cycles, andthe waste liquid treatment is relatively simple, which meets the environmental protection requirements of modernindustry. In addition, the abrasive flow process supports automation and mass production, further improving productionefficiency and reducing overall costs.
The abrasive flow process has a wide range of applications, especially in handling complex structured workpieces. Forexample, in the polishing of inner grooves in long molds, traditional methods are difficult to achieve uniform results, whilethe abrasive flow process can efficiently cover the entire groove surface by adjusting parameters, achieving 1-3 levels ofimprovement and achieving consistent polishing quality. In addition, this process can also be used for the machining ofhigh-precision parts such as impeller blades and turbine nozzles, ensuring the stability of shape and accuracy, andimproving product performance and lifespan.
