Micro deburring for precision parts using magnetic abrasive finishing method

Using the developed electromagnetic inductor for deburring micro burr, more detail characteristics of the performance are analyzed. Experiments were carried out to verify the influence of each conditions: volume of powder, height of gap, rotational frequency of the inductor and feed velocity. Proper deburring conditions are suggested to satisfy the productivity and the accuracy. In addition to deburring efficiency, the influence to surface roughness is analyzed. To improve the surface roughness and impurity, a method of coolant supply and component of abrasive powder are investigated. It is proved that the continuous flow of coolant and the Fe powder without abrasive is effective for deburring and surface quality.
