A skiving apparatus is provided for at least partial removal of the surface of an least approximately tubular body having a center axis, in particular of a plastic pipe, comprising a clamp assembly having a center axis and at least one clamp member for clamping the skiving apparatus to the tubular body, a skiving assembly comprising a skiving arm unit, a skiving knife arrangement disposed at a first end of the skiving arm unit, and a skiving arm support that connects the clamp assembly to the skiving arm unit. The skiving arm unit is connected by its first and second ends to the skiving knife arrangement and the skiving arm support and is pivotable in the common plane with the center axis of the clamp assembly in such a way that the skiving knife arrangement keeps its orientation relative to the center axis of the clamp assembly in every pivoted position of the skiving arm unit. A clamp assembly as a tool holder for a tool such as a skiving tool is also provided, for machining an approximately tubular body having a center axis, in particular a plastic pipe, having a center axis, a mandrel disposed coaxially with the center axis of the clamp assembly, and at least one clamping device disposed on the mandrel and directed substantially radially outwards.

A square-shaped bar-peeling insert and insert-holder designed with pockets to hold two such square-shaped inserts. Each insert has four peripheral sub-surfaces and corners. Between each adjacent pair of corners is a cutting edge which includes a straight wiper sub-edge and two at least partially curved peeling sub-edges respectively located on opposing sides of the wiper sub-edge. The corners of the insert are inwardly disposed relative to an imaginary square formed by the sub-edges.

A portable turning machine includes a support placed on and fixed to a floor, a ring base supported by the support, a turning ring that is turnably supported by the ring base and arranged on an outer circumference side of a collector ring, a motor for turning ring that turns the turning ring, and a tool that is attached to the turning ring and is used for performing corrective machining of the collector ring. The ring base has a structure that is dividable into a lower dividable type ring base and an upper dividable type ring base. The turning ring has a structure that is dividable into a lower dividable type turning ring and an upper dividable type turning ring.

A method for adjusting an inlet guide of a peeling machine controls a peeling material using the inlet guide in relation to a peeling head carrying peeling tools in such a way that the volume per unit length of the peeling material, which volume is to be machined by the peeling machine, is minimized while producing a bright steel having excellent surface quality. Furthermore, a peeling machine provides appropriate measuring equipment in order to be able to carry out the method described above.

A load bearing panel member having a first portion, a second portion, and an appearance surface portion is formed by injection molding such that the first portion includes a plurality of ribs forming a grid pattern on the first portion and another plurality of ribs extending toward the periphery of the first portion which may be non-orthogonal to each other and to the ribs forming the grid pattern. An appearance surface portion attached to the first portion and second portion of the panel member forms an integral hinge between the first and second portions of the panel member. The panel member may be configured as a floor panel of a vehicle.

An internal channel may be formed within each of the non-orthogonal ribs by injecting a gas into the rib during the molding process forming the panel. An appearance surface portion attached to the first portion and second portion of the panel member forms an integral hinge between the first and second portions of the panel member.

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.
