摘要： A chip-removing tool for deburring bores, which laterally open into a cylindrical recess for example, comprising a shaft; a cutting head with at least one cutting wedge on the circumference, said cutting wedge being paired with a flute and having a cutter, which extends in an axial direction at least in some sections, carries out a cutting process on the basis of a relative movement between the tool and a workpiece, and lies on a virtual cylindrical rotational surface with a diameter that corresponds to the nominal diameter of the chip-removing tool, and at least one cutting wedge- and flute-free surface region; at least one fluid channel closed on the cutting head side and extending through the shaft and into the cutting head; and at least one puncture channel which starts from the fluid channel and comprises an opening that lies in the cutting wedge- and flute-free surface region.

摘要： A colleted bushing includes a collet and a bushing. The collet has a collet proximal end and a collet bore having collet threads. In addition, the collet has a collet bore taper located adjacent the collet proximal end, and a plurality of collet fingers located adjacent the collet proximal end and configured to be inserted into a workpiece hole of a workpiece. The bushing has a bushing proximal end, a bushing bore, a bushing outer surface, and bushing threads formed along a section of the bushing outer surface. The bushing is configured to be inserted into the collet bore and the bushing threads are configured to engage the collet threads in a manner resulting in movement of the bushing proximal end into contact with the collet bore taper causing the collet fingers to be urged radially outwardly and removably locking the collet within the workpiece hole.

摘要： Disclosed is a high-precision wheel cap section burr removing device, including a frame, jacking cylinders, guide posts, a servo motor, a lifting table, a bearing seat, a shaft, a bearing, a rotating table, adjusting guide rails, an adjusting cylinder, a left sliding table, a gear rack, a right sliding table, pre-positioning cylinders, pre-positioning guide rails, a sliding plate I, a sliding plate II, pre-positioning posts, corner cylinder pressure claws, a left burr cutter and a right burr cutter. The precision positioning system and the burr removing cutter system are integrated to reduce the combined error, and the rotating centers of the burr cutters are superposed with the central axes of the cap section burrs to realize high-precision burr removal, thereby effectively solving the problems of deviation and non-uniformity of burr removal at the cap section.

摘要： 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).

摘要： A deburring tool that includes a deburring arm which is held in a flexible relationship with respect to an arbor of the deburring tool. In some implementations, the deburring tool is capable of drilling a hole, deburring the hole with the deburring arm, and machining one or more features in the hole, such as an end chamfer. A plurality of attachment elements are located in the arbor to engage the deburring arm. The deburring tool may also include a second deburring arm that is particularly oriented with respect to one or more cutting elements used for drilling the hole.

摘要： A reverse spot-facing tool for cutting a reverse spot-face in a workpiece using a reverse spot-facing cutter configured to engage a pilot shaft having a first end and a second end is disclosed. The workpiece comprises a through hole having a central axis. The reverse spot-facing tool comprises a stop configured to be located between the first end and the second end of the pilot shaft; a biasing assembly that generates a first thrust force and an equal and opposite second thrust force when the reverse spot-facing cutter is cutting the reverse spot face; and a thrust bearing configured to be positioned between the biasing assembly and the stop. When the reverse spot-facing cutter is cutting the reverse spot-face, the thrust bearing transmits the second thrust force from the biasing assembly to the stop, and the biasing assembly transmits the first thrust force to the workpiece.
