Problems solved by technology

Nevertheless, the tool is particularly disadvantageous in that it is not suitable for inserting
The tool does not have a cutting edge in the central area, so that the workpiece material arranged there cannot be cut during axial plunging
The use of such milling tools is therefore limited and the user must be trained in such a way that he does not exceed the permissible limit of the penetration angle.
It should be added that the conventionally arranged, center-forward arrangement of the end cutting edges results in a marked reduction of the clearance, thereby limiting the maximum possible feed rate of the milling tool when cutting into the material to be machined.

Embodiment Construction

[0051] figure 1 A side view of a first exemplary embodiment of a milling tool 1 is shown, which is intended specifically for milling operations, in particular pocket milling. The milling tool 1 has a base body 3 and a center axis M, as well as an end side 5 which, according to regulations, faces the workpiece during milling of the workpiece. Viewed along the central axis M, the base body 3 has a shank section 7 facing away from the end side 5 , which is provided in particular for clamping the milling tool 1 in a machine tool, in particular to in the chuck.

[0052] The milling tool 1 has at least two (here exactly two) geometrically defined first end cutting edges 9 on the end side 5, wherein the figure 1 In the view of , only one first first end cutting edge 9 is shown, the second first end cutting edge 9 is covered here. from figure 1 visible from the observer's perspective and thus in figure 1 Shown in is the first second end cutting edge 11, here in the embodiment of ...

Abstract

The invention relates to a milling tool with a basic body (3), a central axis (M) and an end side (5), wherein at least two The geometrically defined first end cutting edges (9) each have a first cutting section (13) facing the central axis (M). The milling tool (1) is characterized in that the first cutting segments (13) of at least two of the end cutting edges (9) are designed to rise towards the center axis (M), so that the first cutting The section forms a centering tip (15) that is narrowed in the axial direction compared to the axially outermost points (17) of at least two of said first end cutting edges (9). back.

Description

technical field [0001] The invention relates to a milling tool. Background technique [0002] A milling tool is known from German laid-open document DE 10 2014 106 886 A1, which has a central axis and an end side, wherein a plurality of geometrically defined end cutting edges are provided on the end side. These end cutting edges are subdivided into several segments downwards in the direction of the central axis. This makes it possible to form, by means of the milling tool, beveled cuts, also referred to as “ramps”, which have a relatively steep cut-in angle, in particular a cut-in angle of greater than 10°. [0003] Usually, especially milling tools provided for producing recesses such as pockets or windows in workpieces must first cut into the material to be machined before the actual milling process takes place. Since milling tools have to absorb high radial loads during the actual milling operation, they have smaller chip flutes and preferably more than two cutting edge...
