SUMIBORON ”BN Finish Mill” FMU Type High Speed Finishing of Grey Cast Iron Features l High speed machining vc = 1.500 m/min l Excellent surface roughness Rz=3,2 (Ra=1,0) l Safety structure for the centrifugal force under high speed cutting conditions l Run-out is less than 10µm l Easy assembling method using the setting gauge l Running cost is reduced because of economical insert Application GG25~GG30 (HB200~250) grey cast iron with pearlite matrix, and ferrite matrix (HB130~160) Application examples: engine block, cylinder block, etc Specifications FMU Type: ø80 ~ ø315 mm Insert: SNEW1203ADTR/L Low cutting force type: SNEW1203ADTR/L-S Recommended Cutting Conditions Speed: vc = 800 ~ 2000 m/min Feed: f t = 0,1 ~ 0,3 mm/tooth Depth: doc = 0,5 mm or less Dry cutting Performance l Tool Life Diagram l Estimated Tool Life Cutting speed (m/min) Work material : GG25 HB240 (Pearlite) Cutting speed : vc = 400 ~ 4000 m/min Metal removal rate (cm3) Feed rate : f t = 0,15 mm/toothDepth of cut: doc = 0,5 mm,Dry Work material : GG25 HB240 (Pearlite)Cutting speed: vc = 600 ~ 4000 m/minFeed rate:f t = 0,15 mm/toothDepth of cut: doc = 0,5 mm,Dryl Milling of ductile cast iron and alloy steel casting do not produce the bestresults.l Dry cutting is recommended. Wet cutting will result in chipping of cuttingedges in the early stages due to thermal cracking.
