Abrasive Flow Machining
• It is basically used as a deburring process.
• Developed in 1960 by Extrude Hone Cooperation.
• AFM can be used for;
– Polish and deburr parts internally
– Polish through holes
– Polish intersecting holes
– Calibrate fuel injection nozzles to a specific flow rates
– Difficult to accesses areas
– Remove scratching marks (feed marks) of other processes
– radius
• Uses abrasive grains mixed in a putty (a form of
cement) like matrix which abrades the
surface/burrs from the specific area of the
material.
NEED
• Smooth surfaces – Aerospace and precision
components
