CHIPLESS THREAD MANUFACTURING IN WROUGHT ALUMINIUM AND CAST ALUMINIUM ALLOYS
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.
REIME NORIS – PRODUCT RANGE FOR UNIVERSAL THREAD MILLING CUTTERS EXPANDED
As an innovative manufacturer of threading tools, REIME NORIS offers an extensive range of products for the economic production of threads in a wide variety of materials. The company is now expanding its successful thread mill series NORIS SF R15. In addition to the thread types M, MF and G, this tool is now offered for the production of UNC and UNF threads.
The NORIS SF R15 is a multi-row thread mill for processing a wide range of materials. It guarantees short machining times and high tool life. It should be particularly highlighted that the thread is efficiently produced over the entire depth of the core hole with only one turn, for the type SF SE even with countersinking. With a helix angle of 15° right, these thread mills can withstand high mechanical stress. Optimum results are achieved by the specially adapted interaction of the TiAlN coating with its high hardness and temperature resistance and the profile-corrected geometry.
From now on, the NORIS SF R15 is available from stock in all common standard sizes. For special applications the REIME NORIS team of experts with excellent know-how in thread machining is available.
