Connection between a cutter holder and a tool carrier of an internal-turning head

摘要

For the purpose of rigid connection of the cutter holder (9) to the tool carrier (5), the tool carrier (5) has a driving key (11) on its end side, which driving key is inserted into a corresponding transverse groove (13). The driving key (11) has a specified excess size compared to the transverse groove (13), such that when a setscrew (10) is tightened the tool carrier (5) and the cutter holder (9) are elastically deformed. Laterally next to the transverse groove (13) the surface of the cutter holder (9) is supported on the tool carrier (5).
