Abstract: An apparatus for radially cutting cylindrical material including three rollers mounted with a first frame which is pivotable about an axis of one of the rollers with respect to a second frame which carries a saw arbor. One of the rollers is driven in rotation by a motor, and is geared to the saw arbor to drive the saw blades in rotation. A second roller is movable with respect to the first frame and the first roller, and a third roller is mounted on a hydraulic cylinder to clamp the three rollers against the exterior surface of a cylindrical material. Axial grooves are located on the drive roller to facilitate driving of the material, and circumferential grooves are provided on one of the other rollers to prevent axial displacement of the material subsequent to clamping. A ball screw unit pivots the first frame with respect to the second frame to cause the saw blades to engage the material and make radial cuts into the material. A process for radially cutting cylindrical material is also disclosed herein.
