  • Publication number: 20240058876
    Abstract: Deburring tool for deburring bores with a paired arrangement of cutting blades and a rotationally driven tool holder, wherein in a blade recess of a blade housing, the cutting blades are driven opposite one another with radially outwardly pointing conical cutting edges, so as to be radially displaceable relative to one another by means of a rotatable rocker arranged in a base body of the tool holder, and the rocker is mounted rotatably about an axial longitudinal axis in the tool holder and is resiliently biased in the axial direction, wherein in order to change the cutting blades, the blade housing is mounted axially displaceable and fixable on the rocker and the base body.

  • Patent number: 10183345
    Abstract: A deburring tool with a deburring blade (9) for deburring borehole edges (3, 6) that have a straight or un-round shape, consisting of a base body (12) which is rotatably driven about its longitudinal axis (50), and at the lower end of which at least one blade holder (20) with at least one deburring blade (9) secured therein is mounted on a blade bearing (27) on the side of the base body so as to swivel vertically, and on the outer periphery of the blade holder (20) a control groove (31) which is open radially outward is arranged, into which the freely flexible end (30a) of a flexible spring (30) engages, the other end of said spring being clamped to the base body (12), wherein during the deburring process, the deburring blade (9) is swiveled away from the base body (12) at an angle (51, 52, 53) in relation to the longitudinal axis of the base body (12), and the blade axis (55) of the deburring blade (9) rests, spring-loaded, with its at least one cutting edge (39) against the borehole edge (3, 6) to be deburr

  • Patent number: 10137508
    Abstract: Miniaturized deburring and/or chamfering tool with a cylindrical guide sleeve (2) in which a blade holder base body (5) is arranged in an exchangeable manner, which has at least one receiving slot (20) for receiving and guiding a blade (6) arranged there, which is leaf-shaped and designed so that it can bend along its longitudinal axis, and which, at its free front end, has a cutting head (7) with a deburring or chamfering blade arranged there, wherein an internal cooling of the blade (6) and removal of shavings from the blade (6) are achieved by the fact that the coolant flows around the blade (6) in the receiving slot (20) on at least two facing sides.

  • Publication number: 20140234042
    Abstract: Method for operating a driving device for exerting a translatory and rotatory motion on a drive shaft (1) for driving a deburring tool (29), wherein the at least one deburring blade (32) of the deburring tool (29) performs a continual indexing (=stepwise advancing) rotatory motion along the bore margin (45) and at the same time a lifting motion along the bore margin (45), lifting motion which is oriented in the direction of the bore longitudinal axis.
