H Hardened Steel SUMIBORON One-Use Wiper Inserts - Characteristics - SUMIBORON one-use insert with wiper edge for hardened steel machining - Excellent surface finish similar to grinding - Improved efficiency with higher speeds and feeds - New lineup includes: WG type a for low-feed cutting WH type a for high-feed cutting - Purpose of Wiper Edge - Surface Roughness of Wiper Insert Feed rate ”Wiper” Insert (r =0,8) Standard Insert (r =0,8) ”Wiper” type Feed direction Insert Finishing High feed cutting Finishing High feed cutting Highest peak (f=0,10mm/rev) (f=0,30mm/rev) (f=0,10mm/rev) (f=0,30mm/rev) Work piece Wiper edge Surface Feed rate Roughness Profile Standard Insert WG Type WH Type Feed direction Insert Work piece Highest peak Surface Roughness 0,63µm 1,39µm 1,98µm 9,20µm RZ - Recommended Cutting Conditions (Surface Roughness Standard: Rz = 1,6 ~ 3,2µm) l For optimum effectiveness, use wiper inserts for continuous 220 cutting. Cutting Speed (m/min) l For copy turning, inserts with nose-radius is recommended. WG Type WH Type BNC2010 l Chattering and undulation may occur, please use work and BNC160 machine with high rigidity. 150 WG Type WH Type BNC2020 100 BNC200 Two types are available depending on the feed rate: WG Type WH Type BN2000 WG type: Recommended feed rate: less than f ≤ 0,20mm/rev 50 WH type: Recommended feed rate: more than f ≥ 0,20mm/rev Range of good surface roughness: Rz=1,6µm to 3,2µm 0,05 0,1 0,2 0,3 0,4 Available grades: BN2000, BNC2010, BNC160, BNC2020,BNC200 Feed Rate (mm/rev) - Tool-Setup WG / WH Wiper CNGA / CCGW / WNGA Type Wiper Cutting Edge Position Compensation, Outer Processing 1.
