Wave Ball Mill” for Roughing WBMR Type Features Particularly suitable for die mold machining the WBMR replaceable insert ball nose endmill efficiently roughs complex profiles. Its high feed rate capability is a direct result of a sharp cutting edge which is maintained during the cutting cycle by the special cemented carbide substrate working in parallel with the ultra hard ZX coating. Advantages l Wave shaped cutting edge l Economical M class insert l Precise clamping l High feed rate capability Chipbreaker (Nick type) for r= 25 radial insert ZNMT 4310250-N Performance l Cutting Resistance l Anti-Rotational Mechanism l Insert Life 0,3 Largest Flank Wear (mm) 4 WBMR (D=25mm) Competitor’s Chipping Cutting Resistance (kN) Competitor’s Insert seat Circumferential 0,25 WBMR (D=25mm) B movement of the 0,2 3 A insert caused by cutting forces is 0,15 2 C controlled by 0,1 Without Indexable guide faces A, Endmills 1 0,05 B & C, chipping Insert setting 0 5 10 15 20 Back component Feed component Vertical component so as to allow Cutting Length (m) stable cutting.
