Description
Self-Reversing Tapping Head
Applications:
- Depth control
After the machine spindle travel stops, the tap advances 0.140" ± 0.004". - Example: to achieve a tap depth of 1.000", stop the spindle at 0.860". The tap
will advance an additional 0.140" to 1.000" deep. - NC Machine
Set the torque as high as possible within the safe limits of the tap. The NC machine cutting feed equals (Top Pitch x Spindle RPM). Reverse feed equals 2 X (Top Pitch X Spindle RPM). - Right or left-hand tapping without modification; re-entry cushion
- Please do not use the self-reversing tapping heads as drill chucks.
Features:
- Guaranteed depth control; within ±0.004"
- Chatter-free clutch has positive engagement which allows for a smoother, more accurate operation and more rapid reversal
- Radial Float is self-centering to compensate for hole center misalignment
- The unique Double Spring mechanism produces automatic feed and cushion drive. There are 2 springs for the feed and 2 springs for the reversal
- Pre-set torque control permits easy operation of tap brake torque control
- Head comes complete with 2 collets
