PCT No. PCT/DE91/00036 Sec. 371 Date Jul. 30, 1992 Sec. 102(e) Date Jul. 30, 1992 PCT Filed Jan. 18, 1991 PCT Pub. No. WO91/11280 PCT Pub. Date Aug. 8, 1991.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).
