Patent ID: 6940621

Claim:
An engraving element of an electronic engraving machine for engraving printing forms, comprising: a shaft oscillating around a longitudinal axis with small rotational angles; a drive system for the shaft; a lever attached to an end of the shaft with an engraving stylus for engraving the printing form; a restoring element for the shaft; a damping mechanism for the shaft having a damping element secured to the shaft as well as a stationary damping chamber filled with a damping medium connected to the shaft via a flexible bearing; the damping element being formed of at least one damping disk that is circular at least in regions and extending perpendicular to the shaft; the damping chamber being designed at least as a hollow-cylindrical segment around the shaft into which the damping disk projects; the damping chamber extending at least over the circular regions of the damping disk; the damping medium being a ferro-fluidic fluid; and the flexible bearing comprising a plurality of flexible elements connecting the damping disk to the stationary damping chamber so that as the shaft oscillates the flexible elements bend, the flexible elements together with the ferro-fluidic fluid damping the oscillating shaft.
