The provided method and material-removing tool serve for producing an exact-fit cylindrical bore with a high degree of surface quality and a length that may be a multiple of the diameter from an existing bore with a finishing allowance. In order to reduce the time taken for the finishing by means of a reamer to be performed, it is proposed to use a tool in the form of an impact die, which is formed at the front end with a circular or substantially circular cutting edge, the diameter of which corresponds to the nominal diameter of the bore to be produced, and which tapers from directly behind the cutting edge or behind a front region of a certain length.

The present invention provides an online aluminum wheel burr removing machine which includes a roller bed device (1), a positioning and rotating device (2) and a knife box device (3). A wheel (4) is conveyed to a specified position by the roller bed device (1), the positioning and rotating mechanism (2) clamps and rotates the wheel (4), the knife box device (3) horizontally feeds to cut burrs of the wheel (4), the roller bed device (1) conveys the wheel to next station, meanwhile, next wheel enters the roller bed device (1), and next cutting cycle is carried out. The machining time of the present invention is 25-30 seconds, so that the manpower cost is reduced, the machining efficiency is improved, and positive effects are achieved in hub burr removal.

The invention relates to a deburring tool for deburring edges (1, 1a, 1b), of any desired shape, of recesses in workpieces (19) using at least one cutting blade (2, 2a, 2b, 2), wherein the deburring tool is in the form of a slotting and/or drawings tool which is rotated incrementally about its longitudinal axis and is driven displaceably in an oscillating manner in the direction of its longitudinal axis.

An object is to prolong the life of a ring tool, and improve the productivity of a welded pipe. A ring tool unit is held in a downstream-side end portion of a mandrel to be inserted into a welded pipe currently being manufactured from the upstream side of a welding position, and is used as a cutting tool for continuously cutting a bead produced on the inner surface of the welded pipe, wherein the ring tool unit is formed by fitting a ring tool having a ring-like blade in a sleeve having a circular hole for holding the outer circumference of the ring tool.

A weld cutting machine having a first cutting jaw part (4) and a second cutting jaw part (5), a base frame (500) having fixedly attached thereto the second cutting jaw part (5), a power unit and a transmission mechanism (3). The power unit is connected to the transmission mechanism (3) to arrange for movement of at least one of the first cutting jaw part or the second cutting jaw part (4, 5).

An external weld bead removal system for removing and chopping an external weld bead from a tube includes a weld bead cutting apparatus and a weld bead chopper apparatus for chopping the removed external weld bead. The weld bead cutting apparatus includes a cutting tool operative to cut and remove an external weld bead from a tube. The weld bead chopper apparatus, the weld bead chopper apparatus includes a first blade member, a second blade member mounted adjacent the first blade member, and a chopper actuator operable to forcibly rotate the first blade member about a rotation axis relative to the second blade member such that the first and second blade members cooperatively cut the removed external weld bead into smaller weld bead segments as the removed external weld bead is advanced through the chopper apparatus.

A method of removing flash from a gauge portion of a monolithic precursor test coupon using a flash-removal tool is provided. The flash-removal tool comprises a tool body, extending along a longitudinal tool axis, a tooth, and an engagement surface, spaced apart from the tooth along the longitudinal tool axis. The tooth projects from the tool body in a first direction and comprises a shearing surface, facing in the first direction and located an offset distance away from the longitudinal tool axis in a second direction. The method comprises steps of coupling the engagement surface of the flash-removal tool against a first precursor-coupon end of the monolithic precursor test coupon, orienting the longitudinal tool axis parallel to a longitudinal symmetry axis of the monolithic precursor test coupon, wherein the shearing surface registers longitudinally with the flash, and shearing, using the shearing surface, the flash from the gauge portion.

A welding unit for welding rails of a track includes a shearing device for removing a weld bead. The shearing device includes a head part having a shearing edge and two side parts which are pivotable towards one another and have a shearing edge. A rail base section to be applied to a rail base is associated with each side part. The rail base sections each include an end region facing towards each another having a tooth system for a form-locking connection which is effective in a longitudinal direction of the rail after the two side parts have been applied to the rail.

An apparatus for removing burrs on billets has a supporting element and at least two arms extending from the supporting element. Deburring devices are driven in rotation by burrs of billets. The deburring devices are supported by the arms. The apparatus is driven rotatably and reversibly by a drive between a stand-by position wherein the apparatus is spaced apart from the billet to be deburred and a working position wherein the deburring devices are close to the billet to be deburred and are able to contact a burr.
