A precision case holder engages the extraction groove of the rim of a straight wall case and established a fixed distance between a base of the case and a precision forward surface of the holder. The case may then be inserted into a case trimmer and the holder establishes a repeatable distance between the base of the case and a cutting tool in the case trimmer. The holder includes a tapered slot with edges which engage the extraction groove and a threaded piston which is tightened against the base of the case. The case slides into the tapered slot until the taper resists further sliding, and the piston is tightened to retain the case.

A case mouth trimmer and chamferer includes a clear sliding sleeve covering windows in a barrel portion to capture trimmings. The case mouth chamfer tool may be fixed to a micrometer dial threadedly engaging the barrel. A case adapter bearing is fixed to the barrel to position cases. An end m ill is used trim the case length or a case mouth chamfer tool is adjusted to cut an inside chamfer and the micrometer dial is rotated to adjust the position of the end mill or the case mouth chamfer tool with respect to the case adapter bearing to precisely adjust the amount of material cut from the case. An adjustable cutter holder member slides in a dovetail, is adjusted by advancing and retreating a screw, and is held in place by a set screw. The case adapter bearing is easily changed to chamfer different cases.

A device for preparing the end of a pipe includes a non-rotatable mandrel one end of which is attachable to the pipe. A motor rotates a sleeve around the mandrel and the sleeve retains an arm perpendicular to the mandrel for cutting the pipe. A cam surface on the rotating sleeve moves a cam follower. Movement of the cam follower is converted to rotational movement for turning a feed nut threaded on the mandrel. The rate at which the sleeve is advanced by the feed nut is controlled by limiting the movement of the cam follower.

An automatic movable machine includes a vertical plate and a support plate are fixed, in a perpendicular direction to each other, to a semicircular chamfering angle adjusting plate fixed to a head of the movable chamfering machined, a moving body is provided at the vertical plate on the inside of the pipe or the lower side of the metal sheet, and equipped with an internal roller regulated by a spring contact with the inside of the pipe or the lower side of the metal sheet, the support plate has a fixing bolt, a fixing plate is provided to the support plate, and provided at the front of a gear box, and external rollers are provided at the front of the gear box, and allow the speed of the rotational force of a motor, to be reduced in the gear box and transmit the speed-reduced rotational force.

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 jig and tool are provided for rotating the tool around a pipe or pipeline, for truing the pipe end. An operator can easily installation the jig into the pipe end, with or without the cutting tool installed thereto. The tool can be manually or motor driven for rotation about the jig and the pipe end. The attachment of the tool to the jig enables alignment of the tool's cutting face with the pipe end, with angular and axial adjustment available for obtaining a profile suitable for welding to like pipe ends. In an embodiment, the tool can track the pipe diameter to retain alignment despite out-of-round dimensional variation. The tool is operated and rotated about the pipe end to remove material and, as necessary, the tool is adjusted into the pipe end and the rotation about the pipe end is repeated for incremental removal of material therefrom.

The invention relates to a cutting machine with a receiving area for a tube section and with a tool head (1) which can be rotated relative to the receiving area about a longitudinal axis (L), has at least one cutting tool (6) for machining a tube section end (40) of the tube section located in the receiving area, and has a support component (2), wherein the support component faces the receiving area and has an annular component (3) which rotates relative to the support component (2) about the longitudinal axis (L) and is designed to be randomly supported on a tube wall (42, 42) of the tube section end (40). The invention further relates to a corresponding method for reducing vibrations.

A tube deburring apparatus is disclosed and configured for deburring and beveling a terminal end of a tube. In at least one embodiment, the apparatus provides a deburring mechanism configured for use with a torque mechanism. The deburring mechanism provides a plurality of spaced apart bearings radially arranged about a center axis of rotation of a deburring body of the deburring mechanism and defining an imaginary receiving boundary sized for coaxially receiving the terminal end of the tube therewithin. The deburring body further provides a deburring bit positioned radially inwardly from the bearings, a deburring end of the deburring bit providing a cutting edge configured for selectively contacting the terminal end of the tube when the terminal end of the tube is coaxially positioned within the receiving boundary between the bearings.

An automatic movable machine configured such that: a vertical plate and a support plate are fixed, in a perpendicular direction to each other, to a semicircular chamfering angle adjusting plate fixed to a head of the movable chamfering machine; a moving body is provided at the vertical plate on the inside of the pipe or the lower side of the metal sheet, and equipped with an internal roller regulated by a spring contact with the inside of the pipe or the lower side of the metal sheet; the support plate has a fixing bolt; a fixing plate is provided to the support plate, and provided at the front of a gear box; and external rollers are provided at the front of the gear box, and allow the speed of the rotational force of a motor, to be reduced in the gear box and transmit the speed-reduced rotational force.
