Abstract

An apparatus for deburring foundry cores (3) and similar workpieces, comprising a vibration device, a stationary base (10) which carries the vibration device, and a deburring template (4), is designed and constructed for an effective deburring with a reduced risk of damage to the workpiece, and with less wear on tools such that the vibrating movement of the vibration device occurs exclusively in vertical direction, and that a clearance is absent between the contours of the cores (3) to be deburred and the contours of the deburring template (4), so that the burr is cut off as the core (3) passes through the deburring template (4).
