Secondly, the roughness value of the rake face shall be small when grinding. In order to avoid the phenomenon of chip sticking to the tool, the front and rear tool faces of the tool should be carefully sharpened to ensure a smaller roughness value, so as to reduce the chip outflow resistance and avoid chip sticking to the tool.
The cutting edge of stainless steel parts shall be kept sharp. The cutting edge of the tool should be kept sharp to reduce work hardening. The feed and back feed should not be too small to prevent the tool from cutting in the hardened layer and affecting the service life of the tool.
Stainless steel parts
Then pay attention to the grinding of chip breaking groove. Because the chips of stainless steel parts are strong and tough, the chip breaking groove on the tool rake face should be properly grinded to facilitate chip breaking, chip holding and chip removal during the cutting process.
Finally, it is important to select the appropriate cutting oil because stainless steel has the characteristics of easy adhesion and poor heat dissipation, so it is very important to select the cutting oil with good anti adhesion and heat dissipation in boring. The cutting oil with good performance can not only greatly improve the efficiency, but also effectively protect the tool and extend the service life of the equipment.
