Efficient Removal of Milling Burrs by Abrasive Flow ...

Feb 08, 2021· Various types of burrs are formed during machining, press forming, and laser cutting. Deburring tools with cutting edges as well as wire brushes are widely used for deburring when the burr edges are accessible. When the burr edges are difficult to reach, abrasive flow machining is a good candidate. In this work, the removal of milling burrs is attempted using several types of flow guides.
