In recent decades,superhard blades have been widely used in automobile manufacturing,3C electronics,and other fields that require long tool life and high production rhythm.It also puts higher requirements on the mass production of superhard blades.This paper explored the material properties,manufacturing process,and characteristics of superhard tools and introduced three processing methods for sharpening superhard blades.The paper discussed the mechanical grinding method.Based on the process of small and medium-sized batch manual sharpening,the sharpening process and algorithm required for automated unattended production were developed and integrated into automated machine tool products.
