Analysis of Radial Rigidity about the Hydraulic Expansion Toolholder

Article Preview

Abstract:

Toolholder radial rigidity plays an important role in tool vibration and the quality of machine face. Toolhoder radial rigidity is investigated by the finite element method. The factors such as the fitness between tool and toolhoder, the length of oil chamber bulge, oil pressure and rotation speeds are analyzed in the paper, the results can offer some effectively guidelines and reference for toolhoder machining and processing quality control.
