Interchangeable tool assembly

摘要

The assembly (1) has a tool holder (2) with a cavity (2') retaining processing tools and/or tool adapters. An interface (10) changes the assembly to an interface of a spindle unit, and an adjustably supported retaining element holds the processing tools and/or tool adapters in the tool holder. A pressure fluid channel (20) stays in connection with the cavity of the tool holder and flows into the cavity in a contact surface in which one processing tool and/or tool adapter lies in a tightened condition.
