<p>A device (30) for treating, and especially deburring and chamfering, the ends of pipes comprises an outer hollow cylindrical member (32) and an inner conical member (34) rotatably mounted inside the outer conical member. A guide slot (46) is formed in the wall of the outer conical member (32) and a spiral groove (48) is formed in the outer surface of the inner conical member. A tool (50) has a body (52) and a blade (54). The body (52) is received in groove (48) and the blade (54) projects through the slot (46). An end of a pipe to be treated is placed over the end of the outer conical member (32) and the inner conical member is rotated so as to bring the blade (54) into engagement with the pipe. The tool (30) is rotated to deburr and chamfer the end of the pipe. Pipes of varying diameters may be treated. Three alternative embodiments are described.</p> |
