Machining ball tracks and guiding webs of an inner part for a constant velocity joint in a clamping arrangement includes mechanical machining of at least one first ball track in a first rotational position; rotating the articulated inner part into a second rotational position for machining at least one further ball track; wherein at least one guiding web is mechanically machined during the rotating of the inner joint part from the first rotational position into the second rotational position. A corresponding device is used for machining ball tracks and guiding webs of an inner joint part.

A jig and tool are provided for rotating the tool around a pipe or pipeline, for truing the pipe end. An operator can easily installation the jig into the pipe end, with or without the cutting tool installed thereto. The tool can be manually or motor driven for rotation about the jig and the pipe end. The attachment of the tool to the jig enables alignment of the tool's cutting face with the pipe end, with angular and axial adjustment available for obtaining a profile suitable for welding to like pipe ends. In an embodiment, the tool can track the pipe diameter to retain alignment despite out-of-round dimensional variation. The tool is operated and rotated about the pipe end to remove material and, as necessary, the tool is adjusted into the pipe end and the rotation about the pipe end is repeated for incremental removal of material therefrom.
