Micro-Deburring of Electro-Parts by Powder Blasting

Several types of burrs form on the edges of all machined and stamped parts. These burrs must be removed to prevent interference fits or short circuits, to improve fatigue life or to prevent injury. Despite the full or partial automation of FMC or FMS, deburring operations to obtain workpiece with fine surface quality are difficult to be automated since the occurrence and condition of burr are not constant. This study focused on developing micro-deburring technique for small electro- parts produced by press process. The successful performance was demonstrated by deburring experiment using the powder blasting.
