BuildingtheFEAmodelofaxi- al gripping rigidity about Lengthened shrink-fit holder and Cutting tool system with UG NX to analysis the influence of different magnitude of interference、speed、grippinglength andthicknesson axial grippingrigidi- ty. Obtaining the reasonable magnitude of interference of shrink-fit holder by contrastingrigidity. Based on the economic machining accuracy got reasonable axial grippingrigidity.Through the comprehensive analysis of material of shrink-fit holder,obtaining the principle of the selection of material of shrink-fit holder.Re- search providesa certain oftheoretical guidance onthe design ofthe lengthened shrink-fitholder andcutting tool system and choosing the reasonable processing
