What is a Floating tapping tool holder?


The floating tapping tool holder is a device with a spring inside, which is used for flexible tapping, also called floating tapping.

It can be used on automatic working machine tools, multi-axis tapping machines, and CNC machining centers without synchronous tapping.

When tapping with a lathe or a tapping machine, whenever the depth has reached the set value, the tap is broken due to inertia or due to machine control tolerances.

This phenomenon is particularly prominent when tapping the blind hole thread. With the telescopic compensation tapping tool holder, the flexibility of the tool holder can be used to protect the tap and prevent the tap from breaking when the thread is tapped to the end of the length of the main shaft drop is too large.

When the thread is reversed after tapping, in order to prevent the thread from being damaged when the spindle is reversed, the retractable tapping tool holder also provides compensation in the stretching direction and also relieves the force on the tap when the spindle is first reversed, reducing the tap. Damage to extend the life of the tap.Straight Shank 3/4 ER16 Floating Tap Tool Holder Tapping Chuck
