Abstract

Die Erfindung betrifft einen Fräszahn zum Einbau in eine Fräszahnhalterung eines Erdbearbeitungsgerätes mit mindestens einer in Fräsrichtung, einem Schneidenstützbereich vorgelagerten Schneide (2) mit mindestens einer Schneidkante (3), welcher dadurch gekennzeichnet ist, daß die Größe der senkrecht zur Fräsvorschubrichtung liegenden und die mindestens eine Schneidkante (3) schneidenen Querschnittsflächen des Schneidenstützbereiches in wenigstens einem, von jeweils zwei solcher Querschnittsflächen begrenzten, Bereich etwa gleichbleibt.
Hiermit wird, bei einfachem Aufbau, auch bei Verschleiß der in Fräsvorschubrichtung weisenden Vorschubseite (9) ein effektiver Fräsvorschub ermöglicht.

Figure 00000001
The invention relates to a milling tooth for installation in a milling tooth holder of an earth-working machine with at least one cutting edge (2) upstream in the milling direction, a cutting support area and having at least one cutting edge (3), which is characterized in that the size of the cutting perpendicular to the milling feed direction and the at least one Cutting edge (3) intersecting cross-sectional areas of the cutting support area remains at least approximately the same in at least one area delimited by two such cross-sectional areas.
With a simple construction, this also enables effective milling feed when the feed side (9) pointing in the milling feed direction is worn.
