Abstract
An insert adaptor is configured for providing secure clamping of an insert in an insert pocket. The insert adaptor is configured to be located between an insert and an insert pocket and includes at least one magnetic surface configured for applying a magnetic attraction force to the insert pocket or a shim.
Claims24
An insert adaptor configured to be magnetically retained in an insert pocket of a metal cutting tool, the insert adaptor comprising:
- opposite adaptor top and bottom surfaces;
- an adaptor peripheral surface in turn comprising opposing insert abutment and pocket abutment surfaces, the adaptor peripheral surface connecting the top and bottom surfaces;
- and
- an imaginary median plane bisecting the top and bottom surfaces;
- wherein:
- the insert adaptor is devoid of through holes configured to receive clamping screws, for securing the insert adaptor to the insert pocket;
- one of the insert abutment surface, pocket abutment surface and adaptor bottom surface, comprises a first magnetic surface configured to apply a magnetic attraction force sufficient to ensure that the insert adaptor remains in said insert pocket even when a cutting insert is not secured therein;
- and
- said first magnetic surface is configured to provide said magnetic attraction force by being formed with a first magnet recess, the insert adaptor further comprising a first magnet occupying the first magnet recess.

An insert adaptor configured to be magnetically retained in an insert pocket of a cutting tool, the insert adaptor comprising:
- an adaptor body comprising:
- first and second legs connected to one another and forming an adaptor angle (α1) in a top view of the insert adaptor;
- an inner insert abutment surface formed on a first side of the first and second legs;
- and
- an outer pocket abutment surface formed on a second side of the first and second legs, opposite to the first side of the first and second legs;
- wherein:
- on the first side of each of the first and second legs, the inner insert abutment surface comprises at least two abutment sub-surface projections which are spaced-apart by an abutment-relief recess;
- on the second side of each of the first and second legs, the outer pocket abutment surface comprises at least one magnet recess formed therein;
- a first magnet occupying the at least one magnet recess formed on the second side of the first leg;
- and
- a second magnet occupying the at least one magnet recess formed on the second side of the second leg;
- wherein:
- the first and second magnets apply a magnetic attraction force sufficient to ensure that the insert adaptor is magnetically retained in said insert pocket even when a cutting insert is not secured in said insert pocket.
