Abstract

Best introduced in the object of the main patent no. 409.560, requested on december 15, 1972, by: "arrangement of useful milling tool", which is equipped in particular with reversible cutting plates and equipped with a tool body that rotates circularly and having recesses for receiving the cutting plates, in the recesses of which resting on at least one support surface, optionally with intercalation of an intermediate piece, are previously clamped against two surfaces or seating positions by means of an indexing element. Releasable fastening the various shorting plates, each having a through hole, the fastening elements being introduced, which are substantially cylindrical and which enter the hole of the different cutting plates, in respective bores of the body of the tool and presenting each one of the fastening elements made in one piece, on the periphery of a clamping head attached to a delivery of v shank, a curved clamping surface that follows the curvature of the inner wall of the cutter plate hole and which is applied to the inner wall of the cutter plate hole at a limited pressure point in the peripheral direction of the hole and is made as a conical envelope surface or at least as a fragment of such a surface, characterized in that the hole (4) of each cutting plate (3) is conical at least in the area of the seat of the clamping surface (80) against the wall inside the hole and the angle (oc) between the axial direction (16) of the hole (4) of the cutting plate (3) and the shaft (15) of the bore (14) of the body (1) of the tool that receives the associated clamping element (12, 12a, 12b), in the clamping plane, is substantially equal to the difference of the half-angle (β) of the cone of the clamping surface (20) in the clamping head (19) and of the clamping head (20). Semi-angle (ϒ) of the cone of the inner wall of the hole in the area of l seat of the clamping surface (20). (Machine-translation by Google Translate, not legally binding)
