High-precision ultra-thin superhard material cutting wheels are primarily used for cutting and slotting various electronic components in the information electronics field, as well as precision parts in the machinery industry. They offer a series of advantages, including high precision, narrow kerf, and excellent machined surface quality. High-precision combined cutting wheels refer to multi-blade cutting tools formed by precisely assembling multiple pieces (typically 2 to 41 pieces) of high-precision superhard material cutting wheels with metal or resin bonds, spacers, flanges, and the wheel shaft into an integrated unit.
