A rotating machining device for machining a work piece includes a support housing adapted for mounting on the work piece and a headstock rotatably mounted on the support housing about an axis. The headstock including an internal gear. A drive module is arranged to drive rotation of the headstock about the axis and at least one gear connection is formed between the internal gear and the drive module. The at least one gear connection is positioned radially inside of an outer diameter of the support housing to protect an operator from a pinch point associated with the at least one gear connection.

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.

A tool for machining an outer circumferential surface of a workpiece, with an interface adapted for fastening the tool to a counter interface, and a base body which is cylindrical at least in sections. The base body has a circumferential wall encompassing a mounting space and is configured to be open at the frontal side in such a way that the workpiece can be at least partially accommodated in the mounting space. At least one cutting edge engaging in the mounting space is arranged on the base body for the machining of the outer circumferential surface of the workpiece. The circumferential wall has at least one chip passing recess which is arranged relative to the at least one cutting edge in such a way that chips removed by the at least one cutting edge during the machining of the workpiece can exit through the at least one chip passing recess from the mounting space into an outer surrounding area of the base body.

The present invention relates to a device for deburring tubes, in particular tube ends. Said device comprises a proximal and a distal end and has a substantially basic body (1) with a plurality of contact surfaces (20, 20, 20). It further includes a shaft (2) and a guide chamber (4) in which a guide bushing (6) is displaceably mounted. A spring (5) is arranged in such a manner in the guide chamber (4) that a restoring force is exerted onto the guide bushing (6). A blade (11) is releasably fastenable on the guide bushing (6). A guide groove (19), by means of which the blade (11) is guided, extends along an outside surface of the conical basic body (1). The present invention further relates to the use of the device according to the invention for deburring tubes (17), in particular tube ends.

A cutting tool includes a tool body having a peripherally disposed outer insert receiving pocket and an interiorly disposed inner insert receiving pocket with a cutting insert resiliently clamped therein. The tool body includes a through recess at least partially circumferentially bounded by a recess circumferential surface. A resilient clamping member extends into the through recess. The inner insert receiving pocket is formed by the resilient clamping member and a recess pocket portion of the recess circumferential surface. A chamfering cutting insert may be retained by the resilient clamping member, without the use of an additional, separate clamping device.

An apparatus for cutting a pipe has a base comprising a pipe support having at least one set of lower rollers and an upper frame supporting a cutting apparatus and at least one upper roller. The upper frame is moveable relative to the base between an open position in which the pipe may be inserted between the at least one set of lower rollers and the at least one upper roller, and a clamping position in which the pipe is in contact with the at least one set of lower rollers and the at least one upper roller. The cutting apparatus comprises a grooving member configured to provide an annular groove on an outer surface of the pipe, a cutting member configured to cut the pipe, and a chamfering member configured to provide a chamfer on the outer surface of the pipe between a location of the annular groove and a location of the cut in the pipe.

A deburring tool includes a deburring head and a shaft portion connected to the deburring head. The deburring head includes a conical hollow body, a primary cutting edge and a secondary cutting edge both formed on the conical hollow body. The conical hollow body has at least one flute extending between interior and exterior conical surfaces of the conical hollow body, and at least one recessed cutout defined in the interior conical surface. The primary cutting edge is formed at a junction of a wall surface of the flute and a bottom surface of the recessed cutout. The secondary cutting edge is formed at a junction of a wall surface of the recessed cutout and the interior conical surface.

A pipe cutting tool having: a plurality of rollers; a clamping member moveable between an open position in which a pipe is insertable between the plurality of rollers and a clamping position in which the pipe is secured between the rollers; a cutting apparatus having first, second, and third cutting members configured to optionally sequentially engage the pipe when positioned between the plurality of rollers; a drive motor drivingly connected to at least one of the rollers; and an actuator operatively connected to the drive motor.
