ABSTRACT:
A squaring machine has an elongate housing with a rotatable spindle extending from one end thereof and attached to which is a tool for squaring the end of work piece. At the opposite end of the housing are first and second feed members, the first feed member in the form of a screw which is locked against axial movement within the housing, and the second feed member in the form a nut which is locked against rotation with respect to the housing. The feed nut is rotatably connected to an end of the spindle such that rotation of the feed screw will cause axial movement of the spindle. Also, the machine includes a first and second removable retainers, each of which has a pair of opposing jaws for clamping around a cylindrical work piece, however, the jaws of the first retainer are for grasping a work piece of a different size than the jaws of the second retainer. Within each of the pairs of jaws are a pair of replaceable shoes and each of the pairs of replaceable shows is adapted to retain a work piece of a different size, such that the machine can be used to square a wide range of sizes of work pieces.
