REIME NORIS expands its product portfolio for wrought aluminium and cast aluminium alloys with two newly developed cold forming taps.
Both tool types, like all taps of the “NEO” series, are made of HSSE-PM substrate. However, they differ in geometry and coating in order to achieve outstanding results in the respective field of application.
NORIS SPANLOS NEO AL
The NORIS SPANLOS NEO AL cold forming tap has been developed especially for the machining of wrought aluminium alloys. The geometry with an asymmetrical pressure point shape acts in the forming direction through a relatively steep stroke with very low torque. The stroke on the back is much flatter and thus has a supporting effect. This combination results in an enormous increase in tool life. A DLC (diamond like carbon) coating reliably protects against cold press welds, which are found frequently in these materials.
NORIS SPANLOS NEO GAL
The NORIS SPANLOS NEO GAL cold forming tap has been developed especially for thread forming in cast aluminium alloys. The geometry has a steeply pronounced symmetrical stroke both in the forming direction and at the back. The special feature is a sliding surface in-between, which offers targeted resistance to the particularly high abrasiveness of these cast materials. A multi-layer TICN coating, which has proven particularly effective in cases of abrasive wear, functions as a coating here.
In the standard product portfolio, the metric dimensions common for these materials, up to and including M10, are available, from M4 also with coolant hole. As in the entire range of NORIS SPANLOS tools, these two new types are also available from stock only with lubrication grooves.
