In one embodiment, a disposable surgical rode deburrer has a shank configured to be rotated by a drive device and a housing assembly coupled to the shank. The housing assembly includes a rod guide having an opening sized to receive and stabilize a surgical rod when inserted therethrough into an inner cavity. The housing assembly also includes a cutting bit disposed within the inner cavity that is rotated to deburr an end of the surgical rod. A membrane wiper is disposed between the rod guide and the cutting bit. The membrane wiper has a seal that opens to allow the surgical rod to be inserted therethrough, and substantially closes when the surgical rod is removed. The housing assembly also includes a drive body. The membrane wiper retains within the inner cavity chips, particles or dust created by the cutting bit.

A scraper tool for deburring an edge of an aircraft turboshaft engine casing is arranged to be mounted in a milling device. The scraper tool includes a body including, on a first end, a connection for the milling device and, on a second end, a deburring module including a turning lathe platelet including at least one cutting edge arranged so as to deburr the casing edge. The deburring module includes a guide adapted to contact the edge to be deburred so as to follow the profile of the edge to be deburred without modifying the orientation of the turning lathe platelet.

A beveling method for beveling the edge of the opening of a cross hole (2-1) formed in a workpiece (W) while rotating a conical tool (1), which has conical cutting blade sections (11-1, 11-2), wherein beveling is carried out so that a surface of the same width is formed on the edge of the opening of the cross hole (2-1) by controlling the height of the conical tool (1) and/or the position of the rotation shaft of the conical tool (1) on the basis of a conic section, which is generated when a cutting blade section (11-1, 11-2) is cut with an imaginary plane (V) that contacts the processing point (P) of the conical tool (1) on the cross hole (2-1), and the shape of the edge of the cross hole (2-1) opening.

An apparatus (100) for machining a tubular or round-bar type piece, wherein the apparatus comprises a frame element (102), a machining unit (104), as well as a threaded shaft (110), which is fitted to the frame element in a rotatable and axially immobile fashion and has a first section 110a) provided with a right-handed thread and a second section (110b) with a left-handed thread. The first section is provided with at least one first support element (106a) and the second section is provided with at least one second support element (106b), the mutual distance between the support elements being adjustable in response to rotating the threaded shaft, such that the support elements, for example wheels, are adapted to touch a workpiece and to support and guide the apparatus (100) in the process of machining the piece. At least one of the support elements, such as wheels (106a, 106b), is adapted to be capable of rotating relative to its axis in response to moving the apparatus along the surface of a workpiece.

The present invention relates to a one-touch chamfering-amount adjustment device for a chamfering machine which specifically carries out a chamfering process on the welding bead surfaces of objects to be processed (such as metal sheet materials and pipes). In the present invention, the moment after a chamfering-amount-adjustment piece has been manipulated so as to rotate, a position-setting pin is inserted into a securing recess in the chamfering-amount-adjustment piece and as this happens the chamfering amount is precisely adjusted in units and at the same time locking to the predetermined chamfering amount is automatically maintained, yet nevertheless the adjustment of the chamfering amount is achieved in a straightforward fashion with one touch, and, when the chamfering-amount-adjustment piece is manipulated, a cutter shaft moves vertically and as it does so the chamfering amount is adjusted in such a way that the chamfering amount can be immediately and rapidly adjusted even during working regardless of any cutter rotating action.

A method for removing a weld crown from a weld joint between first and second work pieces includes steps of positioning a rotary milling tool proximate to the joint and at an offset angle to set a cutting arc relative to the joint. The milling tool is positioned so the cutting arc intersects the weld crown, weld toes, and parent metal on each side of the weld joint. As the milling tool traverses the joint to cut away the weld crown, the milling tool may tilt from side to side to compensate for misalignment between the work pieces along the weld joint. An apparatus for weld crown removal holds a milling tool at an offset angle, and provides a tracking mechanism to permit the milling tool to track misalignment between the work pieces, maintaining the cutting arc in intersection with the weld toes and parent metal along the weld joint.

A sleeve cutter is provided for precision cutting of a length of metal tubing or the like. The sleeve cutter includes a mandrel or spindle for supporting a tube-shaped sleeve thereon between a pair of rotary-driven cutting wheels adapted for movement together between retracted positions spaced outwardly from the mandrel, and advanced position with cutting edges in engagement with the mandrel-supported sleeve. Each cutting wheel further includes a shaping step or land for removing any burr or flare from the cut sleeve end.

A cutting tool and mounting system includes a tool carrier arranged to be mounted onto a workpiece, a cutting tool assembly carried by the tool carrier, and a tracking assembly connected to the cutting tool assembly and positioned to follow the contour of an outer surface of the workpiece. The cutting tool assembly includes a cutting tool arranged to be rotated about a longitudinal axis and a tool driving system connected to and arranged to transmit rotary input motion to the cutting tool. The cutting tool is secured by the tool driving system to be fed along its axis of rotation and transversely of its axis of rotation for cutting a workpiece through a wall thickness of the workpiece to impart a beveled surface to a severed end portion of the workpiece.

A machine for cutting or beveling a pipe. A cutter unit rotates around the pipe while cutting any surface of the pipe after gripping and fixing the pipe. The machine includes: a main body which a pipe passes through the center portion thereof to be fixed; and a cutter unit coupled to the main body unit rotates around the fixed pipe to cut or bevel the pipe. The cutter unit may have a rotating unit on one side to pull the cutter unit aside and a locking unit on the other side to restrain or release the cutter unit. An entry control unit operating the cutter unit includes: a lever gear-engaged with an outer side surface of an entry control plate; and a clutch formed on a rotation shaft of the lever such that the restraint is released when the lever is lifted or pressed in the axial direction.
