A tool holder (20) which is a component of a machine tool (10) has a base part (22) fixed to a spindle (16), a tool attachment part (26) for attaching a tool, e.g., a boring bar (24), an elastically deformable portion (28) which connects the base part (22) and the tool attachment part (26), a working axle member (30) which is radially movable across the direction of rotation of the spindle (16) relative to the tool holder (20), a translation mechanism (32) capable of translating the motion of the working axle member (30) into a tilting motion of the tool attachment part (26) with respect to the direction of axle, and an actuator (34) which drives the working axle member (30) in the radial direction. |
