摘要
介绍了PCBN刀具结构型式从钎焊式刀片到整体式刀片的发展过程。新牌号SECOMAX—CBN30 0刀片采用粗颗粒粉末 (2 2 μm)和新的烧结工艺 ,大大提高了刀片的抗冲击韧性 ,将PCBN刀具的应用从传统的车削硬材料 (HRC >45 )、以车代磨扩展到铣削加工领域。通过加工实例反映了PCBN铣刀在提高铣削加工效率方面的优秀品质。
The development history of PCBN cutting tools' composition, which varies from the existing tipped edge and sintered layer type to the newly exploited solid type, is introduced. By utilizing both the thick granule powder (22μm Hexagonal Boron Nitride) and twice-sinter process technology, the fracture toughness of new brand CBN300 is greatly increased, by which the application area of PCBN cutting tools is expanded from traditional turning (to hard material of HRC>45) and the grinding substituted turning to a new horizon of milling. The excellent performance of PCBN milling cutter in increasing milling efficiency is justified by the successful example.
