Pipe Facing Machine System

A pipe facing machine system comprising:

• a pipe facing machine including:
• a body defining an axis;
• a mandrel assembly mounted to the body and arranged to clamp the pipe facing machine on a workpiece;
• a cutting head mounted on the body and arranged to rotate and translate relative to the axis;
• a plurality of drive systems comprising a clamping drive system arranged to drive clamping of the mandrel assembly on the workpiece, a rotary drive system arranged to drive rotation of the cutting head about the axis, and a linear drive system arranged to drive translation of the cutting head along the axis;
• a hydraulic controller connected to the body, the hydraulic controller including a plurality of control elements and hydraulically connecting the drive systems;
• and
• a computer control system operably coupled to the hydraulic controller, wherein the hydraulic controller is arranged to direct and regulate hydraulic oil flow between the drive systems and the hydraulic controller based on signals from the control elements and the computer control system;
• and
• a hydraulic power unit having a single hydraulic pump arranged to supply a hydraulic oil flow to the hydraulic controller via a single hydraulic circuit extending between the hydraulic controller and the hydraulic power unit.
