Description

Schwingungsdämpfer für rotierende Werkzeuge bzw. Werkzeug-Spindeln. Vibration damper for rotating tools or tool spindles.

Die Erfindung betrifft eine auf der Werkzeugspindel, dem Werkzeughalter oder dem Werkzeug selbst drehbar gelagerte Masse, die bei der Bearbeitung auftretende: Schwingungen dämpft. The invention relates to one on the tool spindle, the tool holder or the mass rotatably mounted on the tool itself, the occurring during machining: Dampens vibrations.

Es ist bekannt, daß durch stabile Lagerung, Vergrößerung der Massen an Maschinen und neuerdings durch gefederte Massen an Werkzeugspin deln Schwingungsdämpfung erreicht wird (siehe Werkstattstechnik, 58.Jahrgang 1968, Heft 9,5.452.) Der Erfindung liegt die Aufgabe zugrunde, bei (vorwiegend spanabhebender) Bearbeitung mit rotierenden Werkzeugen an der 'i;erkzeugschneide auftretende Schwingungen zu rediizieren bzw. zu vernichten. It is known that through stable storage, the masses increase on machines and, more recently, by means of spring-loaded masses on tool spindles, vibration damping is achieved (see workshop technology, 58th year 1968, issue 9,5.452.) The invention is based on the task of (mainly cutting) machining with rotating Tools at the 'i; tool cutting edge to reduce or reduce vibrations occurring to destroy.

Die Aufgabe wird erfindungsgemäß dadurch gelöst, daß eine Masse von geeigneter Größe frei drehbar gelagert auf der Werkzeugachse (z.B, Werkzeugspindel, Werkzeughaiter oder direkt auf dem Werkzeug) sitzt. Durch die in der Lagerung vorhandenen Reibung rotiert sie nach Einleitung der Drehbewegung des Werkzeuges frei mit. Eine Bremswirkung , wie z.B. durch axial wirkende Federkräfte ist nicht vorhanden. The object is achieved according to the invention in that a mass of suitable size freely rotatable mounted on the tool axis (e.g. tool spindle, Tool holder or directly on the tool). By the ones in the storage Friction it rotates freely after the start of the rotary movement of the tool. One There is no braking effect, e.g. through axially acting spring forces.

Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, daß größere Standzeiten der Werkzeuge, bzw. größere Schnittgeschwindigkei ten vnd Vorschub, sowie bessere Oberflä.chenqualitäten erreicht weruen. The advantages achieved with the invention are in particular: that longer tool life, or greater cutting speeds vnd Feed and better surface quality are achieved.

Ein AusfUhrungsbeispiel ist in der Zeichnung dargestellt. An exemplary embodiment is shown in the drawing.
