A hinge area and processes of forming the hinge area are described. The hinge area is part of cover of a laptop computer. A material used for the cover is of a certain thickness. Stamping and forming a shape that defines the hinge area is performed on the material. The top of the shape is cut to provide for sides of the hinge area. Squeeze forging operations are performed to thicken the sides, and CNC machining is further performed on the sides.

Systems and methods are disclosed for machining an eyewear frame. One method includes receiving a coupon of material for making the eyewear frame, the frame comprising a perimeter, a front portion and a rear portion; cutting the coupon along the perimeter of the eyewear frame, the cut being from the rear portion of the frame to a predetermined depth from the front portion of the frame; and creating a plastic seam around the frame by further cutting the coupon from the front portion of the eyewear frame.

A tool unit includes a tool head, a motor and a switching drive for the head. The head has a first section with first blades and a second section with second blades. The second section is movable to and fro between a passive and an active position relative to the first section, the second blades being retracted in the passive position, and the second blades projecting axially beyond the first blades in the active position. The drive includes an electromagnet and an actuating armature made from magnetically attractable material and is arranged in the region of action of the electromagnet. The electromagnet is positioned between the head and the motor and is fastened to a housing part of the motor such that it cannot be rotated. The armature is connected fixedly to the second section. A gap remains between the electromagnet and the armature in the passive and active position.

A beveling cutter (1) is provided in which a cutting blade (10) is composed of, when seen from an axial direction (X): an inner cutting blade portion (16) extending linearly toward a rear side R2 in a rotational direction R and toward the outer peripheral side; an outer cutting blade portion (17) extending linearly toward a forward side (R1) in the rotational direction (R) and toward the outer peripheral side on the radially outer side of the inner cutting blade portion (16); and a bending cutting blade portion (18) that connects the outer peripheral end of the inner cutting blade portion (16) with the inner peripheral end of the outer cutting blade portion (17). During a beveling operation, a cutting force vector (V1) applied from the inner cutting blade portion (16) to an edge portion (3) of a workpiece (2) and a cutting force vector (V2) applied from the outer cutting blade portion (17) to the edge portion (3) of the workpiece (2) are directed toward the center in the width direction of a bevel (5) formed by cutting. Formation of Poisson burr can thus be suppressed.

A method for manufacturing a metal shell for casing of electronic product comprises stamping, squeezing and milling a sheet metal at a first area and a second area to form hinge side walls. The sheet metal on the periphery is stamped, squeezed, and milled to form side walls. Insert molding is performed at inner surface of the sheet metal to form an internal molded plastic part and a fine machining of the sheet metal is carried out. The metal shell is integrally formed from a single solid sheet, the manufacturing process is simple and economical as CNC processes are reduced.
