This passivation test was conducted on 4 pieces of 7-flute corner radius end mills.
The passivation process was carried out on the PL-24AX machine using 15000-L abrasive, with a treatment time of 20 seconds per tool.
Observation under a 500× microscope showed that serrations and burrs on the cutting edges were basically eliminated after passivation, which can effectively improve the machined surface quality and chip evacuation performance.Measurement at 1000× magnification indicated that the edge radius (R-value) stably reached 10.76 μm after passivation, meeting the target specified by the customer.
