| 摘要 |
The invention comprises a tool holder (10) for removable connection to a machine tool spindle, the holder (10) having a cylindrical bore (12) of a first diameter terminating in an outer abutment face (14)and configured to rigidly support a cutting tool (26), (e.g., a milling tool), having a substantially cylindrical shank (18) of a second diameter slightly larger than the first diameter. The tool (26) has a shoulder (20) of a third diameter substantially larger than the first diameter disposed between the shank (18) and the cutting teeth (22) of the tool (26), the tool (26) being assembled into the cylindrical bore (12) of the tool holder (10) when the tool holder (10) is at a temperature substantially higher than the cylindrical shank (12), structure (24, 32, 34, or 3S) being provided to apply an axial force on the cutting tool (26) to force the tool shoulder (20) against the outer abutment face (14) of the tool holder (10), thereby providing a rigid support of the cutting tool (26). |
