1. A skiving apparatus for at least partial removal of the surface of a tubular body having a center axis, comprising:
a clamp assembly having a center axis and at least one clamp member for clamping the skiving apparatus to the tubular body wherein, in a mounted state, the center axis of the clamp assembly coincides at least approximately with the center axis of the tubular body, and
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 with a first end and a second end, which connects the clamp assembly to the skiving arm unit, wherein the skiving arm unit is connected by a second end to the skiving arm support in such a way that the skiving arm unit and the center axis of the clamp assembly are in a common plane in the mounted state,
wherein the skiving knife arrangement has a skiving knife,
wherein 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.
