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 4 WBMR (D=25mm)Competitor’s Insert seat 0,3 Competitor’s ChippingCircumferential0,25WBMR (D=25mm) 3 B movement of theAinsert caused by2cutting forces isCcontrolled by1guide facesA,Insert settingBack componentFeed component Vertical componentB&C,so as to allowstable cutting.0,20,150,10,05Withoutchipping05101520Cutting Length (m) Cutting Conditions (Shoulder milling, downcut) Cutting Conditions (Shoulder milling, downcut) vc =200m/min, f t =0.15mm/tooth vc =100m/min, f t =0.15mm/tooth Axial doc : 5mm, Radial woc : 5mm Axial doc : 5mm, Radial woc : 5mm Work Material : C50 Work Material : X 40 CrMoV 5-1(HRC45) Application l Cold Molding Die l Injection Molded Part Example Work Material :X 155 CrVMo 12 1 Flank wear aftercontinuouscutting for sevenhours was lessthan othermanufacturer‘sproduct.Stable cuttingwas observed.(Cr-Mo steel + Stellite-overlay)Wave ball(ø30mm)could cut withoutchattering whileother manufacturer‘sproducts couldnot cut at all dueto chattering.
