Tube squaring machine having axially stationary cutting tool shaft and axially movable tube holding collet

A tool for squaring ends of tubular workpieces, said tool comprising:

• (a) a shaft member having first and second ends with said first end including a clamping member for holding a cutting tool bit therein and the second end adapted to be coupled to a shaft of a drive motor;
• (b) a tubular torque housing having a central bore therethrough, said torque housing having axially extending keyways formed in a peripheral surface thereof;
• (c) means for journaling the shaft member for rotation within the central bore of the torque housing;
• (d) a generally cylindrical axial feed housing having first and second ends and a central bore extending therethrough for receiving the torque housing therein and with axially extending keyways projecting radially outward of the central bore of the axial feed housing, the first end of the axial feed housing having external threads formed thereon, the second end including a circular flange;
• (e) a plurality of key members contained in said keyways of said torque housing and said axial feed housing in a shared relationship;
• (f) a workpiece holding collet assembly affixed to the circular flange of said axial feed housing;
• and
• (g) a feed ring having internal threads for engaging the external threads on the axial feed housing, rotation of the feed ring displacing the axial feed housing and workpiece holding collet assembly in an axial direction with respect to the second end of the shaft member.
