Claim:
1. For preparing opposed ends of polyolefin pipes for fusion into a pipeline, a facer comprising: a frame; a sled reciprocative on said frame along an X-axis; a first servo motor driving said sled; a boom reciprocative on said sled along a Y-axis; a second servo motor driving said boom; a pair of spaced-apart parallel vertically oriented cutting wheels rotatable in unison on opposite sides of said boom about a common Z-axis; a spindle motor driving said pair of cutting wheels; and a controller coordinating operation of said first and second servo motors to cause said cutting wheel common Z-axis to trace a center of a thickness of the opposed pipe ends in a closed loop path and of said spindle motor to simultaneously cause said cutting wheels to face the opposed ends of the pipes as said closed-loop path is traced.
