The new NRS geometry is designed for roughing operations while the NMS geometry is targeted at medium machining and semi-finishing. Both feature a sharp cutting edge design which reduces edge build-up andminimizes cutting pressures, along with edge strength and toughness to deter notch formation and chipping. Their geometries promote good chip evacuation, avoiding the often destructive chip impact typical with high- temperature alloy machining.
This superior chip flow and the resulting low cutting pressures, are particularly important in the aerospace industry because the workpieces are often thin-walled and relatively unstable. Thus, too much pressure on the cutting edge can cause these thin walls to deform.
Other typical applications for the NRS/NMS inserts are measuring instruments in the oil and gas industry and, in secondary applications, austenitic stainless steels which are frequently found in the food industry. The roughing and medium machining inserts are available in a variety of shapes appropriate for these operations.
