| 摘要 |
<p>The invention relates to a tool intended for chip removing machining and of the type that comprises a basic body (1) and an indexable cutting insert (2) that can be connected to the basic body via an interface comprising a primary connecting surface (7) in the basic body and a secondary connecting surface (11) in the cutting insert. Among two co-operating support flanks (24,25) included in the connecting surface of the basic body, one (25) is situated on a level above the other (24) in order to form a lateral support for the cutting insert. In the connecting surface (11) of the cutting insert, contact flanks (31,32) are included that, together with the clearance surface (12) of the cutting insert, form a V-shapedly converging wedge part (50) that can be applied in a seat (15) delimited by the support flanks (24,25), the contact flank being urged against the low-positioned support flank (24) of the basic body, while an upper part of the clearance surface (12) of the cutting insert is urged against the high-positioned support flank (25). By means of the high-positioned support flank (25), large cutting forces can be carried in a dominant line of action, the interface in other respects efficiently counteracting such tendencies to dislodging/turning of the cutting insert that are caused by more moderate forces in other lines of action.</p> |
