Abstract
A turning tool adaptor includes opposite first and second side surfaces and a peripheral surface which extends therebetween. The turning tool adaptor further includes a cutting portion with an insert retaining portion and a clamping portion which extends from the cutting portion. The clamping portion includes a protrusion which extends transversely from the first side surface. The protrusion includes a main abutment surface and spaced apart first and second adaptor clamping bores which open out to the second side surface and also to the main abutment surface. The turning tool adaptor has first, second and third abutment surfaces which are located between the top and bottom surfaces in a side view perpendicular to one of the side surfaces.
Claims28
A replaceable turning tool adaptor (10) having a longitudinal axis (L) defining a forward-to-rear direction (DF, DR), and comprising:
- an adaptor forward end (15) and an adaptor rear end (17) spaced apart from one another along the longitudinal axis (L);
- opposite first and second side surfaces (12, 14) and a peripheral surface (16) extending therebetween;
- a forward cutting portion (18) comprising an insert retaining portion (20);
- and
- a clamping portion (22) located rearward of the cutting portion (18), the clamping portion (22) comprising:
- opposite top and bottom surfaces (40, 42) extending between the first side surface (12) and a main abutment surface (28) which extends parallel to the second side surface (14);
- and
- a protrusion (29) extending transversely from the first side surface (12), and comprising:
- the main abutment surface (28);
- first and second adaptor clamping bores (24, 26) opening out to the second side surface (14) and to the main abutment surface (28);
- a first abutment surface (30) facing in an upward direction (U), away from the bottom surface (40);
- a second abutment surface (32) extending parallel to, and located forward of, the first abutment surface (30);
- and
- a third abutment surface (34) located rearward of the first abutment surface (30), and forming a non-zero surfaces angle (α) therewith,
- wherein:
- the first, second and third abutment surfaces (30, 32, 34) are located between the top and bottom surfaces (40, 42) in a side view perpendicular to the main abutment surface (28).
A replaceable turning tool adaptor (10), having a longitudinal axis (L) defining a forward-to-rear direction (DF, DR), and comprising:
- an adaptor forward end (15) and an adaptor rear end (17) spaced apart from one another along the longitudinal axis (L);
- a first side surface (12), a second side surface (14), and a peripheral surface (16) extending therebetween;
- a cutting portion (18) comprising an insert retaining portion (20);
- and
- a clamping portion (22), extending from the cutting portion (18), and comprising a protrusion (29) extending transversely to the longitudinal axis (L) from the first side surface (12), the protrusion (29) comprising a first adaptor clamping bore (24) and a second adaptor clamping bore (26) spaced apart therefrom, the adaptor clamping bores (24, 26) opening out to the protrusion (29) and to the second side surface (14);
- wherein the first and second adaptor clamping bores have (24, 26) elongated, non-circular cross sections.
