Grooving & Parting-Off VibrationVibration Vibration Parting-Off Holders Carbide Blade Type Sumi-Grip Series Sumi-Grip- Series WCFH 32 WCFS R/L 25 WCFS R/L 20 WCFS R/L 16 WCFS R/L 12 WCFS R/L 10 WCFH 26 Features of Sumi-Grip High Rigidity Low Vibration Good Chip Removal This figure shows a computer generated The figure shows the measurement of This picture show the shape of chips comparison of the distortion of steel and cutting vibration. according to feed rate. carbide holders caused by cutting forces. At high speeds the carbide holder SUMI GRIP produces rolled chip which are experiences for less vibrations than does easily removed. The reduced distortion of the carbide holder the steel holder. Thus, the overhang length makes cutting under harsher conditions and can be extended and cutting speed can be higher feeds possible. increased with the Sumi Grip´s carbide holder. f = 0,05 mm/rev f = 0,08 mm/rev Destortion of Sumi-Grip (Carbide holder) f = 0,1 mm/rev f = 0,15 mm/rev Measurement of vibrations (Overhang of holder: 50 mm) Sumi-Grip Steel holder Destortion of steel holder f = 0,2 mm/rev f = 0,25 mm/rev Time Time Steel holder Work material: Ck 45 (ø 60mm, HB250) Insert width and type : 3 mm, Usable limit WCFN 3A (AC225)Cutting conditions:vc = 150 m/min,Wet Structure of distortions Changed sharp Unchanged sharp Sumi-Grip Beautiful surface finish Oberhang Length of Holder (mm) Work: Carbon steel (ø 60mm, HB250) Width of Insert: 3 mm Cutting Data: vc = 150 m/min, f = 0,1 mm/rev F40 l = Euro stockq = Delivery on request
