ABSTRACT:
An apparatus for simultaneously milling the surfaces of two plastic pipe sections facing one another, aligned parallel to one another, and mounted on a metal pipe. The plastic pipe sections may be milled on the metal pipe since the apparatus is provided with a spur gear having a recess and connected to two circular milling disks having congruent recesses and milling cutters, and arranged on both sides of a forked housing. In a specified angular position, the recess of the spur gear and the recesses of the milling disks form a U-shaped seat which merges in a semicircular end. The rotational axes of the spur gear and the milling disks coincides with the center of the semicircular end of the seat, and the width of the seat is greater than the maximum outer diameter of the metal pipe and smaller than the minimum inner diameter of the plastic pipe sections. The spur gear engages with at least one gear on each side of the forked housing, with the angular section formed between rotational axes of the gears smaller than the angular section formed by the recess of the spur gear. The gears are rotatable in the same direction by means of a synchronous belt drive.
