According to WNT, the precision ground inserts are stable and free-cutting, and feature geometry that delivers soft cutting action to minimise strain on the machine spindles, even at high feed rates.
Examples of the performance benefits include a customer machining rough-forged slabs (material 36CrNiMo4) on a DMU 80 Monoblock 43 kW machining centre using the 4910 system for side milling and slot milling. Despite the WNT holder having one insert less than the system used to date, feed per tooth could be increased by more than 100%, and metal removal rate by 84%, to 193 cm³/min.
