Abrasive Flow Finishing Machine (AFFM-150D)
1.Overview: AFFM-150D is a Non-traditional super finishing technology developed by CMTI, The machine is capable of finishing, deburring and polishing complex and difficult to finish precision components. The process involves extruding an Abrasive filled semisolid media through a workpiece passage. The machine is an ergonomic; user friendly, easy maintenance design with a PLC based HMI controlled system and economically viable alternate for micro and nano finishing. AFFM-150D is equipped with state of the art technologies for finishing components with complex geometry (internal & external) with surface roughness of nanometer. The Nano level surface finishes achieved on components are in the magnitude of ≤ 50 nm Ra*. The machine can be applied to a wide range of finishing operations that will provide uniform, repeatable, predictable results.
