Endforming at its best
Increasing quality and production demands of precision tubes require a more precise tube end preparation upstream of drawing processes. Therefore the leading tube ends need to be properly prepared.
This work step is perfectly covered by the state-of-the-art BÜLTMANN tube pointing machines.
This well established technology based
on combined BÜLTMANN tube pointing machine, type HAM/PH, has been specif- ically developed to handle the increased requirements associated with the pointing of tubes. Due to the combination of both proven pointing methods - folding tag forming and push-pointing - integrated in one machine it is possible to point tubes with small wall thickness as well as tubes with a larger one (ratio > 1:10) in one working station.
As this machine type requires very little space it is perfectly suited to retrofitting into an existing line. Furthermore the simple technical concept offers consid- erable cost benefits as only one machine for this application has to be purchased instead of two.
Lowest noise emissions as well as optimal ergonomics due to the use of tool chang- ing devices are further advantages of the system.
Moreover, the ingenious design of the push-pointer modules makes it possible to retrofit on site already existing folding tag machines with this add-on, so that a “state- of-the-art” pointing system can be used with a low investment.
