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 of PCBN tool structure type from brazed blade to monolithic blade is introduced. The new grade SECOMAX-CBN30 0 blade uses coarse-grained powder (2 μm) and a new sintering process to greatly improve the impact toughness of the blade. The application of PCBN tools from traditional turning hard materials (HRC> 45) Generation grinding extended to the field of milling. Through processing examples reflect the PCBN milling cutter in improving the efficiency of milling excellent quality.
