Tapping unit
Pullmax

The Pullmatic 720/520 can be equipped with a fully automatic tapping unit to further more increase time and cost savings. Two alternatives are available, single unit with one spindle for taps M3 to M8 and a multi unit with 6 spindles, the single tapping unit demands manual tap charges. Both units are fully controlled by the machines CNC.

Both units are mounted on the sides of the upper frame, this design do not require a tool station which further more increases the flexibilty of the Pullmatic series punching machines.

Process:

Pre-punch and if required extrusion of the hole in thin material.
Material positioned automatically to the tapping unit.
The tapping unit automatically taps the hole/extrusion.

Advantages:

Weld and insert nuts used today, increases the number of operations to finish the part, thereby increasing the production cost per part.
Shorter process time with less production time per part, which improves machine time availability.
By utilizing extrusions in material thickness up to 3mm, the thread height will be equal to nut inserts.
Do not generate any chips from cutting the thread.
