Embodiment Construction

[0022] The holder, generally designated 1 , consists essentially of sintered tool steel, is square in plan view and has a substantially planar outer surface formed by four parts 2 , 3 , 4 and 5 lying in one plane. 10( Figure 8 ) permanently fixes a workpiece or a tool to be machined, such as an electrode for electroerosion machining. Sections 2, 3, 4 and 5 are separated from each other by grooves 12, 13, 14 and 15 made therefrom in the jig. Each groove has a right-angled cross-section with substantially planar groove sides and is arranged crosswise so that two opposing grooves 12 and 14 or 13 and 15 are respectively aligned. The groove width of all the grooves is the same, so that the parallel edges 16, 18 of the opposite groove 12, the parallel edges 11, 17 of the opposite groove 13, the The parallel edges 6, 7 and the parallel edges 8, 9 of the opposite groove 15 have a predetermined distance from one another.

Abstract

A holder for a workpiece or tool, in the surface (2, 3, 4, 5; 39; 53; 44; 62) of which a plurality of grooves (12, 13, 14, 15; 26; 42; 55; 65) with substantially planar flanks are made, the opposing edges (16, 18, 11, 17, 8, 9; 41, 43; 54, 56) of which, formed on the surface, have a predetermined spacing, wherein the holder consists of a sintered material, at least in the region of the elastically deformable edges. The holder is fit for the machine clamp device and reduces the manufacture cost.

Description

technical field [0001] The present invention relates to a holder for a workpiece or tool, having formed in its outer surface a plurality of substantially planar sided grooves which form a predetermined distance between opposed edges formed on the outer surface. Such clamps are used to clamp, for example, a workpiece to be machined on the chuck of a machining machine, such as an electric discharge machining machine. Background technique [0002] A clamping device for a tool on a machine tool is known from European patent document 255 042, which essentially consists of a chuck fastened on the machine tool and a clamp for the tool. With the aid of a clamping device, the clamping device can be detached from the chuck and re-clamped on the chuck at will. As a result, the clamp is always clamped to the chuck at exactly the same position in a plane perpendicular to the clamping direction, wherein said plane generally represents the x-y plane. The reference element is an axially p...
