磨料流加工（AFM）通过在这些区域上流动磨料介质，对表面和边缘进行去毛刺、抛光和半径处理。该工艺特别适用于其他加工技术（包括小孔）难以加工的内部形状。机器控制挤出压力、流量和速度。由于研磨作用仅发生在流动最受限制的区域，因此通常使用工具将介质引导至适当区域。 使用不同的研磨剂类型、尺寸、浓度和介质粘度，可以获得各种抛光效果。AFM工艺可用于广泛的精加工操作。它可以在单个工件或多个零件上同时加工多个区域。交通不便的区域和复杂的内部通道可以经济高效地完工。自动AFM系统可以处理千个

ABRASIVE FLOW MACHINING (AFM) DEBURRS, POLISHES AND RADIUSES SURFACES AND EDGES BY FLOWING AN ABRASIVE MEDIA OVER THESE AREAS. THE PROCESS IS PARTICULARLY USED ON INTERNAL SHAPES WHICH ARE DIFFICULT TO PROCESS BY OTHER MACHINING TECHNIQUES, INCLUDING SMALL ORIFICES. THE MACHINE CONTROLS THE EXTRUSION PRESSURE AND THE FLOW VOLUME AND SPEED. SINCE ABRASIVE ACTION OCCURS ONLY IN AREAS WHERE THE FLOW IS MOST RESTRICTED, TOOLING OFTEN IS USED TO DIRECT THE MEDIA TO THE APPROPRIATE AREAS. A VARIETY OF FINISHING RESULTS CAN BE ACHIEVED WITH DIFFERENT ABRASIVE TYPES, SIZES, CONCENTRATIONS, AND MEDIA VISCOSITIES. THE AFM PROCESS CAN BE USED IN A WIDE RANGE OF FINISHING OPERATIONS. IT CAN PROCESS MANY AREAS ON A SINGLE WORKPIECE OR MULTIPLE PARTS SIMULTANEOUSLY. INACCESSIBLE AREAS AND COMPLEX INTERNAL PASSAGES CAN BE FINISHED ECONOMICALLY AND PRODUCTIVELY.
