1. Tapping shank telescopic mechanism
The tapping handle itself has its own telescopic mechanism. This is to prevent the pitch of the double screw and the tap from being smoothly synchronized with the mechanical feed. It must be used within the range of the scaling amount.
①.Excessive elongation
When the elongation limit is exceeded, a black mark will appear, please increase the machine feed rate

②. Excessive compression
The feed of the machine tool is faster than the feed of the tap, and the compression mechanism moves. Please reduce the feed of the machine tool to avoid sticking.

2. When the bottom hole is small (when processing difficult-to-cut materials, etc., there are many phenomena that the bottom hole is not enough), the torque protection mechanism makes the tap idling. In this case, do not adjust the torque (in the case of ZK tapping sleeve), but enlarge the bottom hole.

3. During blind hole tapping, when the Z-axis command in the program is too deep, when the spindle rotation stops, the bottom of the hole cannot be extended because it hits the bottom under the action of the rotating force. When reversing, the original length that cannot be recovered at the exit, the tap is easy to touch the blind hole mouth. In this case, deepen the bottom hole or reduce the command value.

4. In the case of Z-type tapping shank, the fixed feed of the machine, the Z point reversal starts Z rise, the tapping shank is in a shortened state, the Z-axis rises, and the hole is easy to touch the tap. In this case, The Z point comes to a standstill, and the tapping shank rises with the Z axis in the extended state.

5. The repair fee of the tapping tool handle and the tapping sleeve, artificial damage and after the warranty period, the repair and inspection will be charged (basic fee).
