Cutting insert for a tool in particular a milling tool

Abstract

The cutting insert (2) is provided for the high-speed milling of light metals in particular aluminium. According to the invention, a reliable and defined cutting removal and a defined cutting forming may be guaranteed, whereby the cutting insert comprises a cutting guide surface (26) which runs into a machining surface(36), arranged at an acute angle (a) to a cutting edge (8).

Description

technical field [0001] The invention relates to a cutting insert for a tool, in particular a milling cutter, comprising a cutting body comprising a workpiece side face and a front end face, which form a corner region in which Set a cutting edge for cutting the workpiece. In addition, the cutting body has a chip guide surface. Background technique [0002] Such cutting inserts are described, for example, in DE 197 16 818 C2 or DE 20 2004 007 811 U1. The known cutting inserts are used accordingly in face milling. In this face milling cutter a plurality of inserts are fastened distributed around the circumference on a cylindrical tool base body. The tool base body consists of a light metal, in particular aluminum or an aluminum alloy. Due to the relatively soft material, in the prior art a chip guide element or a chip deflector is provided which, when cutting the workpiece, keeps the cut chips away from the basic tool body so that it cannot be damaged. In DE 197 16 818 C2 ...

AI Technical Summary

Problems solved by technology

[0003] But the two chip guide elements only serve to protect the tool base

Especially when machining soft materials such as light metal workpieces made of aluminum, the problem arises that the cut light metal chips are difficult to remove and exhibit a relatively high adhesion capacity

There is thus the risk that these chips cause damage to the workpiece surface
