According to the present invention, a low surface-roughness part (114a) is formed at a first tapered part (114), and, as a result, the roughness of an opening-edge of a groove part (113a) of an internal spline part (113) that opens at the first tapered part (114) is reduced, and surface pressure applied by the opening edge to a tooth (123b) of an external spline part (123) can be reduced. As a result, the opening edge of the groove part (113a) of the internal spline part (113) can be kept from digging into the tooth (123b), and variation, between products, in the insertion load of a second shaft part (12) can be suppressed.

Disclosed herein is a composite sandwich panel that includes a first face portion with fully consolidated comingled first fibers and a first thermoplastic matrix. The composite sandwich panel also includes a second face portion with fully consolidated comingled second fibers and a second thermoplastic matrix. Additionally, the composite sandwich panel includes at least one core portion with partially consolidated comingled third fibers and a third thermoplastic matrix. The at least one core portion is interposed between the first and second face portions. The first thermoplastic matrix is melded with the third thermoplastic matrix and the second thermoplastic matrix is melded with the third thermoplastic. A density of the fibers across a thickness of the composite panel is non-uniform.

A peeling apparatus for at least partially removing an external circumferential surface of an approximately cylindrical body is provided. The peeling apparatus includes: a C-shaped or C-like shaped base body, which has two free ends to form a peripheral opening, the cylindrical body being insertable between the two free ends and positionable concentrically in relation to a center of an incircle defined by the internal face of the base body; at least one external bearing mounted on an external axis positioned at each of the free ends, the external bearing abutting the cylindrical body when the body is positioned concentrically in relation to the center of the incircle; at least one central bearing attached to or positioned on the base body, spaced apart from the free ends and on a central axis; and a blade holder into which a blade is insertable so that the blade extends beyond the incircle.

A peeling machine includes a rotating head installed rotating around an axis of rotation and provided with a central cavity. During use, an oblong product to be worked is disposed and a plurality of support sliders are installed thereon to support respective tools and a plurality of adjustment units configured to move the support sliders in a radial direction with respect to the axis of rotation. The peeling machine also includes a transmission unit configured to transmit motion from a first motor to the rotating head and to make the latter rotate, and also to transmit motion from a second motor to the adjustment units to simultaneously adjust the radial position of the tools.

A peeling plate has upper and lower sides, lateral faces extending between the upper and lower sides, and primary and secondary cutting edges at the transition from the lateral faces to the upper side. The peeling plate in a plan view of the upper side has the shape of a substantially regular n-gon, n being five or six, and n lateral edges lying between the n lateral faces. A primary cutting edge and a secondary cutting edge are formed at the transition from at least one lateral face to the upper surface, wherein active primary cutting edges and active secondary cutting edges are spaced apart from a lateral edge. The lateral edge at the transition to the upper side forming an active cutting corner to the respective active primary cutting edge and active secondary cutting edge.

A tool for machining an outer circumferential surface of a workpiece, with an interface adapted for fastening the tool to a counter interface, and a base body which is cylindrical at least in sections. The base body has a circumferential wall encompassing a mounting space and is configured to be open at the frontal side in such a way that the workpiece can be at least partially accommodated in the mounting space. At least one cutting edge engaging in the mounting space is arranged on the base body for the machining of the outer circumferential surface of the workpiece. The circumferential wall has at least one chip passing recess which is arranged relative to the at least one cutting edge in such a way that chips removed by the at least one cutting edge during the machining of the workpiece can exit through the at least one chip passing recess from the mounting space into an outer surrounding area of the base body.
