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 device for electromechanically assisted roller burnishing (EMRB) may comprise: a roller burnishing tool with exactly one current-leading roller burnishing element for burnishing a workpiece, wherein the roller burnishing element represents a first electrical contact element for electrically contacting first location of the workpiece, and a second electrical contact element for electrically contacting second location of the workpiece; wherein the first and the second electrical contact elements can be positioned at a settable spatial distance to one another, so that on moving the roller burnishing element on the workpiece, a current path in the workpiece between the first and the second contact elements is always a constant length.

Disclosed is a rolling tool which serves for workingin particular rolling smoothan inner lateral surface of a cylindrical clearance. For this purpose, the rolling tool has at least one rolling body, which is held in the rotatably drivable rolling tool, and can be taken along by said tool on a peripheral path along the inner lateral surface. The at least one rolling body is inserted into a radial clearance in the rolling tool and can be subjected to a pressurized fluid from the inside to the outside along the radial clearance. The fluid is an aerosol. The aerosol is a fluid mixed with gas and serves for hydrostatic bearing and lubrication.

A device (20) for root-rolling a thread (T) on an object (O) includes: a body (21), an accumulator piston (24) mounted for sealed sliding movement within a body passageway (22), a coarse adjustment screw (25) threaded onto the body, a Belleville spring stack (26) compressed between the coarse adjustment screw and the accumulator piston, an actuator piston (28A or 28B) mounted for sealed sliding movement within a cylindrical opening (23) in the body, and a thread roll (32) rotatably mounted on the actuator piston. A fine adjustment screw is threaded (33) into a first opening (34) on the body, and communicates with a fluid chamber between the accumulator and actuator pistons. The positions of the coarse and fine adjustment screws may be selectively adjusted to controllably vary the fluid pressure within the chamber. The device may be mounted on a machine tool (35) and selectively moved toward the object to root-roll a thread on the object when the object and device are rotated relative to one another.

The embodiments described herein relate to methods, systems, and structures for cutting a part to form a highly reflective and smooth surface thereon. In some embodiments, the part includes substantially horizontal and vertical surfaces with edges and corners. In described embodiments, a diamond cutter is used to cut a surface of the part during a milling operation where the diamond cutter contacts the part a number of times with each rotation of the spindle of a milling machine. The diamond cutter has a cutting edge and a land. The cutting edge cuts the surface of the part and the land burnishes the surface of the part to form a highly reflective and smooth surface. Thus, the diamond cutter cuts and burnishes portions of the part, thereby eliminating a subsequent polishing step.
