A machine for cutting damaged ends off of rolls of wound sheet material includes a saw that moves in a circular motion about the circumference of one end of the roll of material. The circular motion of the saw is coupled with a movement of the saw radially inward toward the center of the axis of the circular movement. The roll is thereby cut in ever increasing depths about its circumference. The machine is mounted on a portable hydraulic lift and controlled by a remote controller positioned a safe distance away from the saw. The machine and the roll of material can be more easily aligned through the use of an alignment track.
