两种新型ＰＣＢＮ刀具目前，美国制造业开始使用两种新型ＰＣＢＮ刀具，扩大了ＰＣＢＮ刀具的使用范围。第一种是ＣＢＮ含量高的ＰＣＢＮ刀具（ＣＢＮ含量高达９０％）。这种刀具的抗压强度高，耐冲击韧性好，但缺点是热稳定性差和化学惰性低；第二种为复合ＰＣＢＮ刀具。...
Two new PCBN tools Currently, the U.S. manufacturing industry has started to use two new PCBN tools to expand the use of PCBN tools. The first is a PCBN cutter with high CBN content (CBN content up to 90%). The high compressive strength of this tool, impact toughness, but the disadvantage is poor thermal stability and chemical inertness is low; The second is a composite PCBN tool. ...
