Lengthened shrink-fit holder is one important part of high speeding tool system. Its gripping rigidi-ty directly affect the quality of the processed parts and machining efficiency. Building the FEA model of axi-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、gripping length and thickness on axial gripping rigidi-ty. Obtaining the reasonable magnitude of interference of shrink-fit holder by contrasting rigidity. Based on the economic machining accuracy got reasonable axial gripping rigidity. Through the comprehensive analysis of material of shrink-fit holder, obtaining the principle of the selection of material of shrink-fit holder. Re-search provides a certain of theoretical guidance on the design of the lengthened shrink-fit holder and cutting tool system and choosing the reasonable processing parameters.
