Effective Deburring of Micro Burr Using Magnetic Abrasive Finishing Method

Abstract:

Micro burrs formed in micro parts are not subject to be removed by the conventional deburring method for marco parts. Magnetic abrasive deburring method which was proved to be effective for small burrs are applied for deburring the micro burr in electric gun parts used in TV monitor. A specific magnetic inductor is designed and manufactured for this part. To improve the deburring performance, vibration table is used for increasing the relative velocity. To evaluate the deburring capability and surface finishing, edge shape, surface roughness and composition of surface material are measured precisely. It is verified the chemical composition of surface is not affected by the powder composition when the proper powder are used with coolant.
