The new S-Cut SC-Uni solid-carbide milling cutter from Sheffield-based WNT (UK) Ltd (
www.wnt.com) has an S-curve feature on the cutting edge and an extremely irregular pitch for soft-cutting and smooth-running capabilities.
These characteristics not only have a positive impact on tool life but also improve the surface quality of the workpiece. Furthermore, WNT says the soft cutting action allows feed rates to be increased, to help reduce cycle times.
With WNT’s S-curve geometry, the helix angle becomes smaller until the inflection point is reached. From this point onwards, the helix angle increases, providing improved cutting performance along with a smoother cutting action.
In addition, S-Cut’s irregular pitch counteracts the vibrations (from cutter to workpiece to machine tool) caused by ‘entry and exit frequencies’ when making the cut.
This results in a stable machining process with hardly any visible chatter marks. Furthermore, the full capabilities of a milling spindle can be used, along with higher depths of cut at large angles of engagement.
The S-Cut SC-Uni is designed for machining steels and stainless steels.
