ABSTRACT:
A base for supporting a rotatable spindle shaft and chuck assembly of a motor driven threading machine for rotation about a spindle axis is comprised of axially spaced apart upright support members transverse to the spindle axis and rigidly interconnected by means of a torque tube having opposite ends welded thereto. The spindle shaft, which carries chuck units on opposite ends thereof, extends through the torque tube and is rotatably supported by bearings adjacent the upright support members. A pair of support rails extend through openings therefor in the support members and have ends extending radially outwardly from one of the support members to provide a cantilever support arrangement for the tooling carriage of the threading machine. Additionally, the support members, portions of the support rails therebetween, and the torque tube facilitate the mounting of drive motor and gear box units for the machine.
