四、ＰＣＢＮ切削刃的质量和稳定性所能达到的零件表面质量是硬质零件加工的一个重要指标 ,并且它主要由进给量和刀尖圆弧半径所决定 (见图 4 )。切削刃的几何精度和切削刃质量也是很重要的。因此 ,通过适宜的切削刃来保证高的切削刃质量是很必要的。采用可重复使用的切削刃也
Quality and Stability of PCBN Cutting Edge The surface quality of a part that can be achieved is an important indicator of the machining of a hard part and it is mainly determined by the feed and the radius of the tip of a tool (see Figure 4). The geometry of the cutting edge and the quality of the cutting edge are also important. Therefore, it is necessary to ensure a high cutting edge quality with a suitable cutting edge. The use of reusable cutting edge also
