在CIMT＇95上,瑞典SECO(山高)刀具公司展出了全新概念的Octomill铣刀及可转位刀片,使人耳目一新。Octomill是从传统的使用方形刀片铣刀基础上发展起来的铣刀新系列。它所配用的可转位刀片的刃口由方形刀片的四个增加到八个(见左图)。由于刃口的增加,单刃加工成本下降了25%。此外,Octomill还具有下列突出的优点更具安全性.刀垫与刀片的一体化设计,配以135°的相邻刃角,增强了刀片的强度。更大的切削余量.使用单刃的切削余量为5mm,如使用双刃(见右图),可将切削余量提高到12mm。更小的表面粗糙度.由于对刀片的断屑槽进行了特殊设计,Octomill的加工面能达到Ra<1μm的表面粗糙度。
On the CIMT’95, Sweden’s SECO (Seco) Tool Company offers a completely new look at Octomill cutters and indexable inserts. Octomill is the new family of milling cutters that have evolved from the traditional use of square-blade inserts. The edge of the indexable insert that it is equipped with is increased from four of the square blades to eight (see left). Due to the increase of the cutting edge, the single-edge processing cost has dropped by 25%. In addition, the Octomill is also more secure with the following outstanding benefits: The integrated design of the pad and blade, combined with an adjacent corner of 135 °, enhances the blade’s strength. Larger cutting allowance. The cutting allowance is 5 mm with a single edge, and the cutting allowance is increased to 12 mm with a double edge (see right). Smaller surface roughness Due to the special design of the insert chipbreaker, the machined surface of Octomill achieves a surface roughness of Ra <1μm.
