Self - Reversing Tapping Head

Applications:

● Depth control

   Top will advance 0.140" ± 0.004" after machine

   spindle travel stops. Example: to achieve a top

   depth of 1.000", set spindle stop at 0.860" will

   advance is an additional 0.140" to 1.000" depth

● NC machine

   Set torque as high as possible within safe limits

   of the top. NC machine cutting feed equals

   (top pitch x spindle RPM). Reverse feed equals

   2 x (top pitch x spindle RPM).

Features:

● Guaranteed depth control; within ±0.004"

● Chatter-free clutch’s positive engagement

   allows for a smoother, more accurate tapping

   operation and more rapid reversal

● Radial float is self-centering to compensate for
