Embodiment Construction

[0028] refer to figure 1 , where the upwardly facing lower support surface 3 of the cutting bit 1 is shown, but the upper surface is not shown in this view. The lower bearing surface 3 is a complete hexagon with six sides 9 and in its center a fixing hole extending perpendicularly to the surface 3, which extends through the entire cutting head 1 and through Fastening screws (not shown) play a fixed role. The peripherally extending edge surfaces 4, 4' do not completely follow the hexagonal structure of the bearing surface 3. Conversely, adjoining the bearing surface 3 is a parallel lands trapezoidal relief or clearance surface 4', while the triangular clearance surface of the main cutting edge 5 is slightly inclined with respect to the parallel lands clearance surface, which belongs to the hexagonal on the same side as and only in contact with the lower bearing surface at corner 13. At the intersection with the upper surface 2, which in this illustration is facing downw...

Abstract

Cutting insert (1) used for milling has a flat upper surface partly serving as a face and a parallel lower bearing surface (3) connected to each other via a peripheral edge surface (4, 4'). The upper surface has a hexagonal shape and defines cutting edges (5) where it intersects with the edge surface. The edge surfaces define at least six partial surfaces lying at about 60 degrees to each other at least in the region adjacent to the cutting edges. The intersection of the upper surface and the edge surface next to a main cutting edge assigned to a hexagonal side defines at least partly also the bezel (7) assigned to the hexagonal sides. The cutting insert has a pair of active surfaces defined on two free surfaces between which at least one further free surface lies and enclosing an angle of about 60 degrees . An Independent claim is also included for a milling cutter having a cutting insert support having one or more holders for the cutting inserts.

Description

technical field [0001] The present invention relates to a cutting bit for milling, the bit has an upper surface and a lower support surface, the upper surface can be at least partially used as a rake surface, and the lower support surface is substantially parallel to the upper surface, wherein the upper surface and The lower surfaces are joined together by a peripherally extending edge surface, the upper surface is substantially in the shape of a hexagonal perimeter and forms cutting edges where it intersects with the edge surface, wherein at least in the area adjoining the cutting edges , the edge surface is formed with at least six clearance surfaces, and these clearance surfaces are each inclined at an angle of about 60° to each other. [0002] The invention also relates to a milling tool with a cutting bit carrier that can accommodate corresponding cutting bits. Background technique [0003] The principle of a substantially hexagonal cutting bit with a hexagonal basic s...
