2 CBN-EHB Epoch CBN High Precision Ball End Mill Features Newly designed low cutting force high-strength flute shape Helix flute design for excellent cutting performance Applications from roughing to finishing High-strength cutting edge to improve tool life New high helix flute design to reduce cutting forces High-rigidity design improves machining accuracy High-quality flute edge improves surface roughness Dedication to high accuracy and long tool life Bigger core diameter to increase rigidity and to maintain high accuracy machining Conventional CBN-EHB Cross section Cross section Bigger core diameter PAT.P New grinding method for improved surface roughness in finishing Conventional CBN-EHB New grindingg method Achieves high-quality flute edge with less grinding marks Input of diameter correction value To improve final machining accuracy, input the real tool diameter stated on the case into CAM system. Zur Verbesserung der finalen Bearbeitungsgenauigkeit, sollte der auf der Verpackung aufgedruckte, tatsächliche Werkzeugdurchmesser im CAM hinterlegt werden. Per una superiore precisione di esecuzione programmare nel vostro sistema CAM il diametro reale rilevato, che troverete. Para mejorar la precisión del mecanizado final, programar en el CAM el diámetro real de la herramienta indicado en la caja. Pour améliorer la précision de l usinage final, saisissez le diamètre réel de l outil indiqué sur le boîtier dans le système FAO. Para melhorar a precisão da maquinação final. Introduzir o diâmetro real da ferramenta no sistema de CAM conforme tabela de medição. Measured tool diameter stated on case D MMC Hitachi Tool Engineering Europe GmbH
