摘要： The invention relates to a method of manufacturing a cutting member (3). According to the method, a single side (9) of a carrier (1) of the cutting member is provided with an auxiliary layer (11). The carrier is provided with a cutting edge (7) by means of an electrochemical machining device (19), an electrode (21) of the electrochemical machining device being arranged on a side (15) of the carrier remote from the auxiliary layer. According to the invention, the auxiliary layer is provided as far as the cutting edge to be provided on the carrier, and, after the cutting edge has been provided on the carrier, the auxiliary layer is maintained on the carrier as a layer which is functional for the cutting member. In this manner, the auxiliary layer has a double function and is thus utilized in a better way. In a preferred embodiment, the auxiliary layer mainly comprises SiO2 and has a thickness of below 200 nm, preferably below 100 nm. In this embodiment, an edge (33) of the auxiliary layer, which is present at the location of the cutting edge of the carrier, constitutes an auxiliary cutting edge or even a main cutting edge of the cutting member, so that the cutting member has improved cutting properties and an improved service life. The cutting member is used in a shaving head (37) according to the invention and in a shaving device (35) according to the invention, which shaving device comprises a shaving head. The shaving head further comprises a manipulator (51) which is arranged near the cutting edge of the cutting member for moving hairs (75) along the cutting edge during cutting. In this manner, the auxiliary layer of the cutting member also is a protective layer protecting against wear, corrosion and providing mechanical resistance.

摘要： In a method for electrochemical machining the working distance (dw) is set by contacting the workpiece (2) with the electrode (3) (phase I), increasing the distance between the workpiece (2) and the electrode (3) by a first distance (d1) (phases II-III), detecting whether the contact between the electrode (3) and the workpiece (2) is broken (phase IV), and further increasing the distance between the workpiece (2) and the electrode (3) by a second distance (d2). Owing to this method very small working distances can be set with a limited risk of short-circuiting and flash-over.

摘要： The invention relates to a hair removing apparatus (1) comprising two co-operating hair processing members (17, 19), which are movable relatively to each other in a direction of movement (X). The hair processing members comprise, respectively, a first plate-shaped carrier (21) and a second plate-shaped carrier (27), which extend substantially parallel to the direction of movement. The two carriers are positioned with respect to each other, viewed in a Z direction substantially perpendicular to the carriers, by means of a plurality of positioning members (29), which are arranged so as to be some distance apart, viewed in a direction parallel to the direction of movement. At least one of the two carriers has a comparatively low bending stiffness. As a result, a comparatively small and uniform gap is present between the two carriers, and the friction force acting on the carriers in a direction parallel to the direction of movement is also comparatively small.

摘要： The invention relates to a method of forming one or more through-holes in a metal workpiece, such as shaving foils or shaving combs, by means of an electrochemical machining apparatus (ECM apparatus). To this end, the method is characterized in that, during machining, the workpiece is provided on a substrate of an electroconductive, electrochemically inert material, such as a noble metal (alloy), in particular a noble metal (alloy) which is predominantly composed of Pt. Preferably, the workpiece is clamped onto the substrate. By virtue of said measures, rounding of the edges between the holes formed and the surface of the workpiece, which is clamped down on the substrate during machining, is reduced substantially. This has a favourable effect on the formation of sharp cutting faces.
