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.

A knuckle deburring cutter and a method of knuckle for removal of burrs at a lower ball head hole of a knuckle and burrs in the locations where the lower ball head hole, a pinch bolt hole and a pinch bolt slot intersect one another. The knuckle deburring cutter includes a cutter shank in a circular bar shape having a diameter less than that of the lower ball head hole. A deburring cutter head is positioned at an end of the cutter shank with the shape of the deburring cutter head matching that of the pinch bolt hole. A sharp-angle part of lettering is positioned at an end of the deburring cutter head with a width of the sharp-angle of lettering being less than that of the pinch bolt slot. The knuckle deburring cutter and associated method provides benefits, such as low rejection rate, ease of machining, short production rhythm and the like.

The present disclosure provides a deburring apparatus and a deburring method that does not require a positioning engagement part that is engaged with a fixed part of a machine tool. The deburring apparatus (10) includes a housing (1) with a shank (11), a transmission rod (3), a recovery rod (5), a tilting shaft (4), a spring (6), a holder (7), and a rotary-to-rectilinear motion conversion mechanism (9) with a plunger (8). The spring forces the recovery rod toward the tilting shaft. The holder for fixing the cutter (101) is arranged on the tilting shaft in a manner rotatable through a predetermined rotation angle. The rotary-to-rectilinear motion conversion mechanism separates the first flange portion from the second flange portion and brings the plunger into contact with the recovery rod on the tilting axis (43) when the holder rotates in a direction opposite to the rotation direction of the shank (11).

The invention relates to a deburring blade for deburring the edges of holes on workpieces, containing at least one cutting blade, which comprises at least one cutting portion having at least one cutting edge with an associated free surface which is designed as a cutting part, an associated control surface adjoining the cutting edge and being designed as a non-cutting part, the cutting blade being held in a tool holder which is rotatable about an axis of rotation in at least one direction of rotation, and the cutting edge transitioning into a helically twisted surface which forms a continuous transition from the cutting part to the non-cutting part.

A cutting tool for metal is described that comprises a main body produced from metal, wherein the main body is reinforced with a reinforcing material. The cutting tool can be a milling tool, a turning tool, a drilling tool, a thread cutting tool, a broaching tool, a turn broaching tool, a reaming tool, a deburring tool, a combination tool and/or a multifunctional tool.

The invention relates to a deburring tool for deburring edges (1, 1a, 1b), of any desired shape, of recesses in workpieces (19) using at least one cutting blade (2, 2a, 2b, 2), wherein the deburring tool is in the form of a slotting and/or drawings tool which is rotated incrementally about its longitudinal axis and is driven displaceably in an oscillating manner in the direction of its longitudinal axis.

The disclosure provides a deburring apparatus comprising a housing which includes a shank and a mechanism chamber arranged along a shank-axis; a plurality of transmission rods which are arranged around the shank-axis in parallel with the shank-axis and fixed to the mechanism chamber; a tilting shaft which is arranged along a tilting axis passing through a tilting center on the shank-axis and is tiltable around the tilting center. The tilting shaft includes a flange portion, a receiving portion which includes an abutting surface, is arranged in the flange portion, and is penetrated by the transmission rods respectively; and a rod portion which is arranged on a distal end side of the flange portion and holds a cutter. Each of the transmission rods includes a bulge portion which is arranged on a plane perpendicular to the shank-axis and passing through the tilting center and is in contact with the abutting surface.

Provided is a tool bracket in which a spindle body is inserted and the spindle body can be smoothly tilted. The tool bracket includes a housing including a cylinder chamber extending along a cylinder axis; a tilting body having a tilt axis configured to tilt about a tilt center, the tilting body to which a spindle body is attachable, the tilting body tiltable with respect to the cylinder axis; a rotation stopper member extending in a radial direction from the tilt axis, the rotation stopper member disposed in the tilting body; and a receiving groove extending along the cylinder axis, the receiving groove arranged in the housing.

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 deburred, and executes spring-loaded swiveling movements that follow the contour of the borehole edge (3, 6) as the deburring tool is rotated, wherein the blade axis (55) of the deburring blade (9), in the home position in which it is swiveled away from the base body, forms an angled swivel position (52, 53) that deviates from the 90-degree position, and in that a backstop is assigned to the deburring blade (9), which prevents it from swiveling back into the position in which it is swiveled at a 90-degree angle from the base body (12).
