ABSTRACT:
A portable pipe cutting machine comprises a frame, an arm having opposite ends and supported on the frame for pivotal movement about a pivot axis between the opposite ends, a cutting wheel rotatably mounted on one of the ends of the arm, and a hydraulic piston and cylinder unit between the frame and the other end of the arm for pivoting the arm to displace the cutting wheel toward a pipe to be cut which is supported on rollers mounted on the frame beneath the cutting wheel. A manually operable variable displacement pump delivers fluid under pressure to the piston and cylinder unit to displace the arm toward the pipe, and an electric drive motor unit is supported on the arm for displacement therewith and includes an output end axially slidably interengaged with a drive shaft for the cutting wheel.
