The results showed that the steel after combined treatment had higher surface hardness and wear resistance, and prolonged the service life of cutting tool.

结果表明，该钢经复合处理后，具有较好的表面硬度和良好的耐磨性，显著地增加了刀具的使用寿命。

Since only a few of the cutting edges are engaged with the workpiece at a time, heavy cuts can be taken without adversely affecting the tool life.

由于同一时间只有部分切削刃切削工件，因此可以在对刀具寿命没有不利影响的情况下承担重型切削。

youdao

In many cases of stainless steel cutting operations with carbide tools, a tool life strongly depends on flank notch wear of depth of cut rather than average flank wear of main cutting edge.

硬质合金刀具在不锈钢加工中，其刀具耐用度主要是取决于后刀面边界磨损而不是主切削刃后刀面的平均磨损量。
