The ADC tapper, in which the limit device is incorporated to
determine thread depth automatically, can decide thread depth
accurately. Variations in accuracy of depth tapping is ±0.1.
Please use TC type tap, which has no torque limiter. In addition,
traditional TCC collet having torque limiter can be used.
It automatically corrects the error in the machine and feed tap pitch
by the action of the float mechanism (tension-compression), which
can make it tapping with high accuracy
