In this passivation test on 7-flute corner radius end mills, the PL-24AX machine and 15000-L abrasive were used, with a processing time of 20 seconds per tool. A total of 4 tools were passivated. Observations under a 500x microscope showed that serrations and burrs on the cutting edges were largely eliminated after passivation, which can effectively improve the surface quality of machined parts and chip evacuation performance. Measurements at 1000x magnification confirmed that the post-passivation R value stably reached 10.76μm, meeting the preset target and verifying the effectiveness and reliability of the passivation process.
