不锈钢零件刀具刃口应保持锋利。刀具刃口应保持锋利，以减少加工硬化，进给量和背吃刀量不宜过小，以防止刀具在硬化层中切削，影响刀具使用寿命。
The cutting edge of stainless steel parts should be kept sharp. The cutting edge of the tool should be kept sharp to reduce work hardening. The feed and back cut should not be too small to prevent the tool from cutting in the hardened layer and affecting the service life of the tool.

然后注意断屑槽的磨削。由于不锈钢零件的切屑具有强韧的特点，刀具前刀面上断屑槽修磨应合适，从而使切削过程中断屑、容屑、排屑方便。
Then pay attention to the grinding of the chip breaking groove. Due to the strong and tough nature of the chips in stainless steel parts, the grinding of the chip groove on the front face of the cutting tool should be appropriate, so as to facilitate the interruption, holding, and removal of chips during the cutting process.
最后选用合适的切削油由于不锈钢具有极易产生粘结和散热性差的特点，因此在镗削中选用抗粘结和散热性好的切削油相当重要，性能良好的切削油不仅可以大幅度的提高效率，而且可以有效的保护刀具，延长设备的使用寿命。
Finally, select the appropriate cutting fluid. Because stainless steel is prone to bond and has poor heat dissipation, it is very important to select cutting fluid with good anti bonding and heat dissipation in boring. cutting fluid with good performance can not only greatly improve efficiency, but also effectively protect tools and extend the service life of equipment.
