<p>Pipe machining device in the form of a pipe cutting device, pipe gripping device, or pipe rectangular end facing device, including a non-rotating fixed or positionable gripping device (2) for gripping a pipe to be machined; a rotatable machining device (4), that is mechanically connected to the gripping device (2), but is placed so that it can be rotated at least 360° relative to the gripping device (2), around a rotation axis (10) that is aligned with a pipe center axis of the pipe to be machined, defined by the gripping device (2); a rotatable, motor-drivable tool shaft (20) for the tool (24) that machines the pipe, placed in the rotatable machining device (4); distinguished in that the rotatable machining device (4) is equipped with a cold-air blower device (60) that has a pressurized air inlet (68) and a pressurized air outlet such that the pressurized air outlet is used as a cold air outlet (62) and directed onto the part of the tool (24) that contacts the pipe during machining, blowing the tool (24) with cold pressurized air.</p> |
