摘　　要：Capto刀柄与HSK刀柄均为高速数控机床配套使用的刀柄,其动静态刚度、可靠性、安全性等直接影响到被加工零件的质量和加工效率,这两类高速刀柄和主轴接口在工况下的扭转变形是影响整个主轴-刀柄系统刚度及其性能的重要指标。文章运用有限元分析方法分析了两种刀柄在相同过盈量、扭矩等情况下和主轴接口的刚度特性及其规律,研究结果为合理选型高速刀柄提供理依据。Capto toolholder and HSK toolholder are all supporting the use of the toolholder in the high speed CNC machine, and their static accuracy, reliability and safety directly affect the quality of the part and machining efficiency. What mainly affects the integrated rigidity of toolholder and spindle and its performance is the torsional deformation, which is caused by these two kinds of high speed toolholder and spindle interfaces. This paper, using FEM method analyses the rigidity of both toolholders when at the same magnitude of interference, torque and so on. And the results provided theoretical basis for the reasonable selection of high speed toolholder.
