| Zusammenfassung: | The invention relates to an abrasive flow polishing fixture for a spiral groove of a twist drill. The fixture comprises a flow channel guide part, at least one abrasive drainage opening I is formed in one end of the flow channel guiding component, an abrasive drainage opening II symmetrical to the abrasive drainage opening I is formed in the other end of the flow channel guiding component, and a twist drill spiral groove mounting hole is formed between the abrasive drainage opening I and the abrasive drainage opening II symmetrical to the abrasive drainage opening I. The clamp further comprises twist drill bit clamping components and twist drill rod clamping components, wherein the number of the twist drill bit clamping components is equal to that of the twist drill spiral groove mounting holes. The twist drill bit clamping part is provided with a twist drill bit protection groove; during polishing, one twist drill corresponds to one twist drill spiral groove mounting hole, one twist drill bit clamping compon |
