METHOD AND DEVICE FOR DEBURRING

摘要

A burr removing method comprises the steps of disposing a cutter (11) having a circular cutting edge such that the flank of the cutter (11) is substantially in parallel with the surface of a steel piece (1) on which a burr (2) exists and the following formula is satisfied with respect to the burr (2): R/2 + W/2 < DELTA < R - W/2 wherein W shows the width of the burr (2), R shows the radius of the cutter (11), and DELTA shows the shortest distance from the center of the cutter to the center line of the width of the burr; and cutting the burr (2) located at an edge of the steel piece (1) by the cutter (41) by relatively moving the cutter (41) toward the outside of the steel piece (1) along the lengthwise direction of the burr (2).
