A method measures an edge of a workpiece by scanning. The scanning is performed by a scanning tool mounted on a moving head of an edge-facing machine while that moving head is moved along the edge to be measured before, during or after an edge facing tool of the edge-facing machine that faces the edge. The method can be performed by an edge-facing machine that includes at least one edge facing tool and that further includes a scanning tool mounted on a movable head of the machine, which head is movable along an edge of a workpiece.

A device for holding a milling and/or grinding machine, particularly hand-held milling and/or grinding machine, in a position for machining an edge at one end of a pipe. The holder device includes at least one rotatable roller which can be laid against the pipe inner side or the pipe outer side and by which a connecting part of the holder device, on which the milling and/or grinding machine can be arranged, may be moved along the edge.

A method for manufacturing a metal shell of an electrical connector, includes: S1: providing a tube, where a mating opening is formed at an opening of the tube, for a tongue of a mating connector to be inserted therein; S2: rolling a perimeter of the mating opening inward to form a flanging, where the flanging is configured to guide the mating connecter to enter the tube; and S3: cutting the flanging using laser, so that an aperture of the mating opening is enlarged to a predetermined size. A metal shell manufactured by the above method, and an electrical connector having the metal shell.

An attachment for a drill comprises a shank with a chuck configured to mount the attachment to the drill. A housing on the shank comprises a threaded end and a hollow chamber. A compression bladder having a tubular opening through it is configured to be inserted into the hollow chamber. A tube comprising a sanding or cleaning surface located on the inner surface of the tube is configured to be insertable into the tubular opening of the compression bladder. A threaded lid having a circular opening that is at least the same diameter as the inner diameter of the tube is configured to mount onto the housing at the threaded end and compress the compression bladder thereby reducing the diameter of the tubular opening and compressing the compression bladder against the tube to secure the tube within the housing.

An apparatus for burnishing a tube includes a housing having an inner surface defining a passage. A shaft provided in the passage is rotatable therein. An eccentric cam extends from the shaft and is rotatable therewith. The tube is configured for positioning within the passage and around the cam such that rotation of the cam simultaneously removes burrs from inner and outer surfaces of the tube.

A pipe de-burring assembly for de-burring a pipe and a pipe fitting includes a cylinder that has a pair of wells each extending therein to insertably receive a respective one of a pipe and a pipe fitting. A shaft extends lengthwise through the cylinder and the shaft is rotatably coupled to a power tool to rotate the cylinder. A plurality of first bristles is each of the first bristles is coupled to the shaft and each of the first bristles frictionally engages an inside surface of the pipe fitting for de-burring the inside surface of the pipe fitting. A plurality of second bristles is each coupled to the cylinder and each of the second bristles frictionally engages an outside surface of the pipe to de-burr the outside surface of the pipe.

A rotary bit configured to deburr and swage an end of a tube, comprising a first end configured to deburr and swage the end of the tube, and a second end configured to be secured to a rotary device, wherein the first end includes a plurality of blades that extend axially along the first end and radially outward from the rotary bit, the plurality of blades including a plurality of leading blades and a plurality of finishing blades, the leading blades configured to initially deburr and swage the end of the tube upon insertion of the rotary bit into the end of the tube, and the finishing blades configured to complete deburring and swaging of the end of the tube, the finishing blades extending radially outward from the rotary bit to a greater extent than the leading blades.

A deburring device includes a cylindrical body with a receptacle for receiving a pipe. The cylindrical body includes an abrasive surface provided in the receptacle, which is configured to simultaneously deburr at least two surfaces of a pipe inserted into the receptacle.
