    “VEGA” Porous Vitrified Bond Wheel for Wafers Finishing Grinding 画像

    Higher surface roughness realized by intermediate processing and final processing of SiC and GaN wafers
    ■Higher surface roughness is realized by the combination of ultra-fine diamond abrasive grains and vitrified bonds of large and fine porous combination structure.
    ■Spontaneous blade generation is realized and cutting quality is maintained by bonds that can make ultrafine shredding.
    ■Stable high-quality surface and low processing cost can be realized.

    The "ME" and "MC4" metal bonds have higher cutting performance and durability than conventional bonds. By using a forming technology, they reduce the amount of polishing required after beveling work. Since this reduces the processing time and saves consumable supplies, the total processing cost is reduced. Wheels of desired groove shapes can be made owing to our advanced groove forming technology.Electroplated wheels using ultrafine abrasive grain are also available.

  • Diamond multi-layer wheels

    A single wheel of this type can perform multiple grinding processes such as rough grinding, pre-finishing, and finishing. This allows multiple processes to be performed with a single machine without replacing tools, which reduces processing time. Multi-layer wheels with a combination of metal bonds for rough grinding, resin bonds for pre-finishing, and resin bonds for finishing are available.

  • Diamond notch wheel for semiconductor wafers
