Abstract

Eine Handwerkzeugmaschine hat einen Linearantrieb zum Bewegen eines Werkzeugs längs einer Arbeitsachse, z. B. ein motorisch betriebenes, pneumatisches Schlagwerk. Wenigstens zwei Tilger sind in der Handwerkzeugmaschine zum Dämpfen von Schwingungen längs der Arbeitsachse vorgesehen. Eine resonante Anregung einer Schwingung des ersten Tilgers längs der Arbeitsachse erfolgt bei einer ersten Resonanzfrequenz, welche sich von einer zweiten Resonanzfrequenz des zweiten Tilgers für die Schwingung längs der Arbeitsachse unterscheidet.
