DEBURRING TOOL AND METHODS FOR DEBURRING EDGES OF HOLES

摘要

Deburring tool with deburring blade (9) for deburring bore edges with straight or unrounded shape, consisting of a base body rotatably driven about its longitudinal axis, at its lower end at least one knife holder (20) with at least one deburring blade (9) attached thereto in the vertical direction pivotally a base-body-side blade bearing (27) is mounted, and on the outer periphery of the knife holder (20) in the radial direction outwardly open control groove (31) is arranged, in which engages the free bendable end of a spiral spring (30) whose other end clamped on the base body is, during the Entgratvorganges the deburring blade (9) from the base body by an angle (51, 52, 53) is pivoted to the longitudinal axis of the body and the knife axis (55) of the deburring blade (9) with its at least one cutting edge on the deburred Bore edge spring loaded rests and upon rotation of the deburring the contour of Bohr ungsrands following spring-loaded pivoting movements performs, the deburring blade (9) in the retracted from the body rest position with its blade axis deviates from the 90 degree position, angled pivot position (52, 53) and that the deburring blade (9) is associated with a backstop, which prevents pivoting back into the pivoted by 90 degrees from the body out position.
