Non-cutting thread former for cast aluminum alloys

With two newly developed tapping-Tools expanded Rhymes Noris his product portfolio for Aluminum wrought alloys and Cast aluminum alloys, Both tool types, like all thread formers of the "NEO" series, are made from HSSE-PM substrate. However, they differ in properties such as geometry and coating in order to achieve outstanding results in the respective area of application.

The "Spanlos NEO GAL" thread former was specially developed for thread forming in relatively difficult to form aluminum cast alloys. The geometry has a steep stroke. It is symmetrical in the forming direction and on the back. The specialty of the tap for the cast alloys is the sliding surface in between. It offers targeted resistance to the particularly high abrasiveness of the cast alloys. A multi-layer TICN coating works as a coating, which has proven particularly useful in the case of abrasive wear.

The "Spanlos NEO AL" thread former was specially developed for the machining of wrought aluminum alloys. The geometry with the asymmetrical shape of the press studs works in the forming direction due to a relatively steep stroke with very little torque. The stroke on the back is much flatter and therefore has a supportive effect. This combination brings an enormous increase in tool life. A DLC (diamond like carbon) coating reliably protects against cold press welds, which often occur in these materials.
