Various components of an electronic device housing and methods for their assembly are disclosed. The housing can be formed by assembling and connecting two or more different sections together. The sections of the housing may be coupled together using one or more coupling members. The coupling members may be formed using a two-shot molding process in which the first shot forms a structural portion of the coupling members, and the second shot forms cosmetic portions of the coupling members.

A milling tool for producing chamfer surfaces at workpieces. It has a cylindrical shaft and a cutting part, which has at least two end cutting edges, which are each located on a cone jacket surface and which run in a spiraled convex manner in the direction of rotation, and which each extend from a radially outer cutting corner to an inner cutting corner on the end side. To broaden the area of application of the milling tool to processes, such as the “ramping” or the linear diagonal plunging, respectively, the circular milling, the spot-drilling, or the waterline milling, the end cutting edges merge at the inner cutting corner into center cutting edges, which are located on a cone jacket surface with a tip angle of above 180°, and which run with a positive chip angle into a region of the milling cutter center located in the milling cutter core.

Provided are a deburring tool and a deburring apparatus capable of, when the contact angle between the deburring tool and a workpiece changes, following the portions to be deburred, and thus always capable of performing uniform deburring against contraction, deformation, and strain of resin products.

A deburring tool includes a nav. tool 9 in which a cutting tool 7 is inserted and fitted and that has an opening 41 exposing a blade portion of the cutting tool 7, opening edge portions 42 and 43 of the opening 41 each include a profiling guide portion 45 expanding, in the circumferential direction of the profiling guide member, in a sector shape that is centered on the center axis of the nav. tool 9, and the profiling guide portion 45 is formed to have a conical shape in side view.

A deburring tool includes a shank attached at a first end to a chuck and a working portion at a second end of the shank. The working portion includes a first end portion closest to and joining the second end of the shank at a first end of the first end portion, a second end portion furthest from the shank, and an intermediate portion disposed between the first end portion and the second end portion, a first end of the intermediate portion joining a second end of the first end portion and a second end of the intermediate portion joining a first end of the second end portion. The intermediate portion tapers continuously from a largest diameter at the first end of the intermediate portion to a smallest diameter at the second end of the intermediate portion, and deburring cutter members provided on the second end portion adjacent the second end of the intermediate portion.

A cross hole deburring tool which performs rotary cutting on a cross hole burr occurring on a cross ridgeline part between a through path and an inner circumferential surface of a spherically-shaped hollow part. A tool main body includes a tip part and a shank, and the tip part has a shape obtained by setting a diameter axis of a circle, setting an eccentric axis parallel to the diameter axis and away therefrom by a predetermined eccentric distance, setting a closed region in a bow shape formed of a line segment obtained by cutting the eccentric axis by the circle and a minor arc on the circle by defining this line segment as a chord, setting an outer surface shape of a bow-shaped solid of revolution formed by rotating this bow shape about the eccentric axis, and taking this outer surface shape as the shape of the tip part.

Device for machining an end of an elementary panel for its subsequent friction stir welding, the elementary panel comprising a metal body defining two opposite faces, the machining device comprising a chassis, at least two guiding members configured to guide a first face of the elementary panel, at least one machining tool mounted on the chassis, the machining tool being positioned between the two guiding members and at least one pressure member mounted on the chassis and configured to exert a pressure on a second face of the elementary panel so as to press the elementary panel against the guiding members along the horizontal reference direction.

Methods and structures for forming anodization layers that protect and cosmetically enhance metal surfaces are described. In some embodiments, methods involve forming an anodization layer on an underlying metal that permits an underlying metal surface to be viewable. In some embodiments, methods involve forming a first anodization layer and an adjacent second anodization layer on an angled surface, the interface between the two anodization layers being regular and uniform. Described are photomasking techniques and tools for providing sharply defined corners on anodized and texturized patterns on metal surfaces. Also described are techniques and tools for providing anodizing resistant components in the manufacture of electronic devices.

A deburring method includes rotating a case, a sleeve and a drive gear together with a spindle of a machining tool; transmitting rotating torque from the drive gear to a driven gear to rotate a tip tool together with a reciprocating shaft; receiving reactive torque to the tip tool in a reverse direction of a rotational direction of the case by a workpiece contact with the tip tool so that the reciprocating shaft rotates in a reverse direction of the rotational direction with respect to the sleeve; moving the reciprocating shaft to a basal end direction against an elastic force of a second spring with the driven gear sliding with respect to the drive gear; and cutting the workpiece by the tip tool.
