Grooving & Parting-Off Parting-Off Holders Carbide Blade Type Sumi-Grip Series Sumi-Grip- Series Features of Sumi-Grip High Rigidity This figure shows a computer generated comparison of the distortion of steel and carbide holders caused by cutting forces. The reduced distortion of the carbide holder makes cutting under harsher conditions and higher feeds possible. Destortion of Sumi-Grip (Carbide holder) Destortion of steel holder Structure of distortions Changed sharp Unchanged sharp Low Vibration The figure shows the measurement of cutting vibration. At high speeds the carbide holder experiences for less vibrations than does the steel holder. Thus, the overhang length can be extended and cutting speed can be increased with the Sumi Grip's carbide holder.
