Abstract

The invention relates to a disc milling tool for milling or sawing metal blanks, with a disc-shaped base body (2) at or on its edge region with a plurality of movable Replacement cutting elements (3), such as in particular cemented carbide milling cutters, wherein a seat ( 10), and the design of the cutting element (3) is stress-fitted or form-fitted in abutment contact with the base (10) or against the base (10), or is loaded on it, so that at least this is perpendicular to the plane of the disc The cutting forces acting on the cutting elements (3) are respectively absorbed by the respective bases (10), wherein the bases (10) have a base bearing surface (11) which is defined by a raised edge (9), whereby the raised edge ( 9) and the base (10) form a loading recess open on one side for positively fitting loading of the cutting element (3).

Description

technical field [0001] The invention relates to a disc milling tool for milling or sawing metal blanks, in particular such as metal tubes or bars, with a disc-shaped base and a plurality of blades arranged on the disc-shaped base. Replaceable cutting element in the edge region with fastening means for detachably fixing the cutting element in the edge region of a disc-shaped base body, the invention also relates to a cutting element for use in a disc milling tool element. Background technique [0002] DE 34 25 699 PS discloses such a knife of the same applicant. The cutting tool is used for machining, especially for high-feed milling process, which has a disc-shaped base and a plurality of replaceable cutting elements arranged in the edge region of the disc-shaped base, which is just like hard Alloy milling cutters or indexable inserts with fastening means for detachably fastening the cutting element to the edge region of the disc-shaped base body. In order not to reduce t...
