Extrusive Abrasive Polishing

‌Principle‌: EAP uses abrasive media (e.g., diamond or silicon carbide microparticles mixed with a polymer-based elastic medium). The media is extruded through internal holes or surfaces via reciprocating motion, polishing complex geometries like molds and micro-cavities. Grinding marks align with the flow direction, achieving optimal surface finish.
‌Features‌: Recyclable abrasives, no dust or harmful byproducts.
‌Applications‌: Precision parts (e.g., automotive/aerospace components) with internal holes, cross-holes, or curved surface polishing.
