ABSTRACT:
The portable lathe 10 for turning a shaft at a job site in the field includes a pair of clamping rings 12 and 14 that are adapted to be centered at spaced-apart locations along a length of a shaft to be refurbished. Extending between the clamping rings are a plurality of glide shafts 40, 42, 56, 58 which slidingly support a split-ring clamshell assembly 68. A cutting tool carrier 100 is affixed to the rotatable ring portion 74 of the clamshell assembly so that when the movable ring is driven, the tool carrier orbits the shaft being refurbished. A feed screw 98 driven by a servo motor 92 translates the clamshell assembly along the glide shafts.
