Coning
• Place the appropriate size coning tool in a vise so that lubricant can flow to
cutting blades (4).
• Set feed nut (3) location as shown in dimension A.
• Slide tubing through collet (5) until end contacts cutting blades (4) and
tighten gland nut (7) just enough to firmly grip tubing.
• Turn feed nut (3) counterclockwise to back cutters away from tubing, and
tighten gland nut (7) with wrench.
• Apply cutting oil through the opening in the coning tool. A medium weight
cutting oil having high sulfur content is recommended. Use cutting oil freely
throughout the cutting operation to prevent dulling the coning blade.
• Turn the feed nut (3) clockwise until cutting blades (4) contact end of tubing.
• Rotate the cutter handle (1) in a clockwise direction while simultaneously
turning the feed nut (3) in a clockwise direction at a rate to assure that the
cutting blades (4) are taking a light cut at all times.
• Continue rotating cutter handle until feed nut bottoms on housing (6), then
rotate cutter handle several more revolutions to face-off the end of the cone.
• Unscrew the feed nut (3), and remove the blade spindle (2) from the coning
tool. Loosen the collet, slide the tubing (8) into the housing (6) until it
extends approximately 100mm (4 inches) and then retighten the collet.
Threading
Place the appropriate sized threading tool on the coned end of the tubing, large
end forward. Apply pressure to start the cutting action and rotate the die holder
counterclockwise until the threads are cut per the cone and thread dimension
table.
