There is disclosed a vibration device for de-burring a workpiece, such as a foundry core 13, 22. The device comprises a de-burring tool 10, 25 having an impact surface with a profile which corresponds with the profile of the region of the workpiece which requires de-burring. The impact surface is vibrated in the clearance between the tool and the profile of the workpiece, so as to de-burr the latter. The vibration device provides flaw-free de-burring of workpieces in automated manner (compared with known manual means) and in a short time period.
