h3. Numertap 100, 200, 300, 700 & 770 Units The NUMERTAP 100, 200, 300, 700 and 770 series tapping attachments with machine tapers, feature a length adjustment screw. This allows the compression stroke to be reduced or eliminated, if desired, to provide more accurate depth control. Adjusting the compression stroke to zero will result in a tension only set-up, the best solution for synchronous tapping. Turning the length adjustment screw counterclockwise reduces the compression stroke but does not affect the tension stroke. The projections of the unit can be adjusted by turning the screw in either direction until the desired length is reached. Changing the length in this manner does not affect the tension stroke. This is an important feature if redundant tools are being set or if reground taps are being used in existing programs. Adjust the compression stroke counterclockwise until the tapping attachment body contacts the shank. This will set for tension only. This is recommended to eliminate or avoid tap elongation in synchronous tapping cycles. h3. Tension-Only, the Best Solution for Synchronous Tapping The NUMERTAP 100, 200, 300, 700 and 770 units can be purchased as tension only units (TT) or can be adjusted to tension only units by following the instructions above. Tension only is the best solution for synchronous tapping. If the unit is purchased as a TT, the tension spring is eliminated during assembly. The unit will be the same length as a TA unit. If a TA unit is adjusted to eliminate the compression stroke, the unit will be 1/4" shorter than its original projection length. NUMERTAP 700 units can be adjusted for tension only, but cannot be used in synchronous tapping cycles. 2007-01-17T12:17:24+00:00 false false 184 true false Numertap 100, 200, 300, 700 & 770 Units The NUMERTAP 100, 200, 300, 700 and 770 series tapping attachments with machine tapers, feature a length adjustment screw.
