METAL REMOVING TOOL, IN PARTICULAR LANCING INSERT |
摘要 |
A metal removing tool, in particular lancing insert, has a holder (10) with a slot-shaped recess (11) and a cutting insert (12) detachably held therein under a prestress by means of an elastically expandable clamping arm (101) designed as one side of the recess (11). The opposite cooperating insertion and bearing surfaces of the cutting insert (12) and slot-shaped recess (11) have a V-shaped cross-section. At its insertion and bearing surface facing the clamping arm (101), the cutting insert has a plurality of substantially flat partial surfaces (124, 125, 126) arranged behind each other in the insertion direction. Two surfaces enclose an obtuse angle alpha and form a salient point at the ridge (127), so that the clamping arm (101) engages the cutting insert (12) between the ridge (127) and the cutting edge (121) in the clamping state. In particular to prevent the cutting insert from being drawn out of its seat, the partial surface (124) engaged by the clamping arm (101) is inclined so as to form a negative angle beta with respect to the bearing surface (128) or the plane defined by the bearing lines of the cutting insert. |
