(Depth limit device)How to set
- 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
① Approach amount setting
Set to F1-5mm. Set slightly slower or equal to the speed of travel of the tap
② Start tapping
③ Spindle movement amount
Amount obtained by subtracting the threading feed amount (F1) by the tap depth setting amount.
④ Feed stop point
Stop the feed of the machine, and let only the spindle (Dwell) turn.
⑤ Dwell time
Dwell time = {Tapper threading feed amount (mm)/ [Tap Pitch(mm) x Rotation (R,P,S)]} x 2
⑥ Tap stop point
Stop spindle rotation, reverse spindle rotation (Dwell), and feed back (setting to the same as the rate at which the tap is fed back).
