Abrasive Flow Machining
Definition of AFM
Abrasive Flow Machining (AFM) uses abrasive-filled polymer media to remove material from workpieces.
It effectively finishes complex geometries and hard-to-reach areas where traditional methods may struggle.
Materials Commonly Flowed
AFM is suitable for a variety of materials, including metals and plastics, making it a versatile choice in the manufacturing sector. It is particularly beneficial for components with intricate designs or tight tolerances, ensuring that every detail is refined to meet exact specifications.
New 3D printed metal technology often faces surface roughness problems, making AFM an excellent option for manufacturers seeking a smoother finish.
How and for whom?
AFM extrudes media through the workpiece under controlled pressure, allowing precise material removal and surface enhancement, which leads to improved finishes, accuracy, and burr elimination.
It is commonly used in aerospace, automotive, and medical device manufacturing for high-quality finishes on different materials. This process is becoming more and more important for Additive Manufacturing (AM). Parts that utilize AM are unattractive and rough, and this is where AFM can help with additive finishing.
