ROTARY TAPERED TOOL HOLDER WITH ADAPTER SLEEVE

摘要

A rotary tapered tool holder (10) includes a body (12) and an adapter sleeve (14) disposed about a portion of the body. The body (12) and the adapter sleeve (14) have front and rear contact surfaces (12c, 12e) with different taper angles. The front contact surfaces (12c) are optimized for an interference fit and the rear contact surfaces (12e) provide an axial stop and support band when the tool holder (10) is assembled into a clamping receptacle (28). Face contact is achieved between a flange contact surface (12k) of the body (12) and a face contact surface (28a) of the clamping receptacle (28).
