WNT broaching system eliminates separate set up time
The WNT broaching system is designed for use on CNC lathes and machining centres to eliminate separate broaching operations that would normally be produced on stand-alone machine tools.
The broaching range includes solid carbide tools (type NPU), certain sizes of which are compatible with WNT's existing Mini-Cut toolholders, and a range of indexable insert type tools (type NPV); with both being available to cut class C11 (DIN138), Class JS9 (DIN 6885) and Class P9 (DIN 6885) grooves.
The tools are available in a variety of widths ranging from 4 to 10 mm, with special widths available to order.
The clamping mechanism for the indexable NPV-type inserts is designed to reduce insert breakage. As a result cutting data can be increased and, as an example, when broaching a 42CrMo4 850 N/mm² steel, the feedrate will be 7200 mm/min at a depth of cut of 0.072 mm.
