NOTE
Before interrupting the cut, back the cutter blades away from the tubing. Use
compressed air or a small brush to remove the accumulation of chips from the
blades and the tubing throughout the coning operation.
8. Continue the operation until the feed nut bottoms on the housing. Turn the cutter handle
several more rotations to face-off the end of the cone.
9. Retract the cutter blades, loosen the gland nut and remove the tubing. Inspect the cone for
surface finish and completeness.
NOTE
Clean the machining chips from the blade and from the collet before coning the
next tube.
Power Coning
1. Secure the tubing in a tube vise. No more than the recommended length of tubing should
extend beyond the face of the vice. See Table 2-7, Recommended Extension Length.
2. Mount the coning tool in a 3/8-inch or 1/2-inch, variable speed power drill. Apply cutting
oil to the end of the tube and slide the coning tool on the tubing.
3. Apply steady pressure against the end of the tubing while the cone is being cut.
Apply cutting oil frequently and liberally throughout the cutting operation. A medium
weight cutting oil with high sulfur content is recommended.
4. The tool will stop cutting when the tube angle and facing is complete.
NOTE
Clean the machining chips from the blade and body of the tool before coning the
next tube.
