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 Metal removal rate (cm3) Flank wear VB (µm) Sumiboron / SumiDia Tools Cutting speed (m/min) Work material : GG25 HB240 (Pearlite) Cutting speed : vc = 400 ~ 4000 m/min Feed rate : f t = 0,15 mm/tooth Metal removal rate (cm3) Depth of cut : doc = 0,5 mm, Dry Work material : GG25 HB240 (Pearlite) l Milling of ductile cast iron and alloy steel casting do not produce the best Cutting speed : vc = 600 ~ 4000 m/min results. Feed rate : f t = 0,15 mm/tooth l Dry cutting is recommended. Wet cutting will result in chipping of cutting Depth of cut : doc = 0,5 mm, Dry edges in the early stages due to thermal cracking.
