ABSTRACT:
A rotary tubing cutter enables automatic tube cutting without requiring manual rotation of the cutter. The apparatus includes a motor driven gear assembly including a blade gear and a feed gear. The feed gear includes a plurality of cam slots that receive pins attached to the cutting blades of the blade gear. Rotation of the feed gear relative to the blade gear effects feeding of the cutting blades. The apparatus is particularly useful for fuel rod tubing of nuclear fuel assemblies.
