Traditional tapping holder allows a tap to move through the z axis in order to cover a machine’s feed discrepancy but this floating possibility can lead to an intensive shook on cutting wedge becuse of inapropreat chip formation in beginning of threading operation (no cutting action, becuse, the work piece material push the tap back), so, we will have a bad wear or low tool life.
For solving the problem, Synchro Tapping holder with small movement allowance around 0.1 mm and rigid system not only help us to address this issue and have a better life but also it can help us to improve torqu’s diagram instability or tab breaking issue
