The Connecting Performance Analysis for a New High Speed and Precision Double-Contact Toolholder

Abstract:

The connecting performance of a new high speed and precision double-contact toolholder (BTF toolholder) is studied in this paper. The mechanics of elasticity and Finite Element Method (FEM) are used to analyze the effect law between the clamping force and the connecting performance, respectively. The contact stress and deformation are obtained for the tapper and surface of flange interface. The optimal clamping force is derived for the BTF toolholder under the limited rotational speed. By comparing with those of the conventional BT toolholder, the BTF toolholder has higher stiffness and outstanding connecting properties. The research results will provide the basic theory and data support for the optimization and application of toolholder.
