摘要： 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).

摘要： A refacing tool includes a feed assembly that holds a first set of cutters positioned for refacing the inner shoulder of a pin or box end of a tubular and a second set of cutters positioned for refacing the outer shoulder of the pin or box end. The axial spacing between the first set of cutters and the second set of cutters is fixed and determined by the geometry of the feed assembly. The refacing tool can simultaneously reface the inner shoulder and the outer shoulder, as well as chamfers.

摘要： A deburring tool includes: a body having a cylinder bore; an anti-rotation body protruding toward inside of the cylinder bore; a cylindrical slide shaft reciprocable inside the cylinder bore, and an elastic body urges the slide shaft toward a cutting depth direction. The slide shaft includes a guide groove having a displacement width for the slide shaft to axially displaceable with respect to the anti-rotation body, and the guide groove moves the slide shaft with respect to the body in an opposite direction to the cutting depth direction as the guide groove receives cutting resistance.

摘要： The invention relates to a cutting tool (10), in particular a chamfering tool. Said tool comprises a tool body (14) which is rotatable about a tool axis (12) and a chamfer cutting element (24) which is mounted on the tool body (14) such that it is radially displaceable by means of a guide (32). The chamfer cutting element (24) is held in radial direction on the tool body (14) by means of a holding arm (42). The holding arm (42) is elastically flexible in radial direction and is disposed at least partly inside a substantially axially extending groove (56) provided on an outer periphery of the tool body (14). Also presented is an indexable insert (30) for such a cutting tool (10).

摘要： A lower drill tool that is structurally configured to receive a bracket, and, to cooperate with an upper drill tool having a pair of spaced apart drill bits. The lower drill tool has part receiving surface, a pair of spaced apart drill bores, a central bore, a centering nub and a biasing member. The drill bores extend downwardly away from the part receiving surface. The central bore is between the drill bores and extends downwardly away from the part receiving surface. The centering nub is slidable within the central bore, and has an upper tip extendable beyond the part receiving surface, positionable between an extended position and a partially retracted position. The upper tip has a conical configuration. The biasing member is positioned within the central bore and biases the centering nub toward the extended position. A drill system and a method are also disclosed.

摘要： The present disclosure belongs to the technical field of hole machining equipment, and provides a hole chamfering device including blades in bilateral symmetry and a blade posture adjusting assembly. The hole chamfering device not only can be fed from the front face of a hole to complete chamfering work on the front face of the hole, but also can solve the problem of chamfering the back face of the hole under the condition that a chamfering tool cannot be directly fed from the back face of the hole. The hole chamfering device can be fed from the front face of the hole to complete chamfering work on the front face and the back face of the hole, and meanwhile, can remove burrs in the hole, thereby meeting the machining requirement of conventional chamfering of the hole.

摘要： A lateral disc cutter for morcellating and decorticating tissue of an intervertebral disc from between adjacent vertebrae. The device can be arranged in a retracted configuration for insertion via an access tube, and in an extended configuration for cutting of tissue in the target region. The blades may be extended to contact the concave endplate in an orientation that is substantially parallel to a mid-plane of the intervertebral disc. Blades of the device may be configured with a convex profile that substantially conforms to the concave shape of the endplate for enhanced contact length between the blade and the endplate. In some embodiments, the blades are configured for removal and replacement without need for tools, with the blades selectively determining a maximum displacement width of the morecellator assembly.

摘要： A deburring mechanism with a rotatable countersink, a cylindrical shaft, a conical cutting contour and a cylindrical cutting edge configured to mount to a driven workstation shaft so that when a workpiece comes in contact with the cutting edge, burrs are removed from the workpiece. The deburring mechanism has a safety device attached to the shaft and adjacent the countersink. The safety device has a rotationally symmetric body with openings through which removed burrs move, a circular outer guard, a mounting portion with legs and a hexagonal mounting contour corresponding with an interior bore of the driven shaft and configured such that a driving connection of the countersink only occurs when the safety device is assembled and overlaps the transition area with a protective contour.
