    The Features :
    1)Various directions of producing chemicals or metallurgical products. Provide with high efficiency of grinding and durable lifetime.
    2) Stable manufactures technics. Provide with fine roughness of wafer surface.
    3) Back Grinding wheel is the precision processing tool used in the process to grind unnecessary wafer back side and make the wafer back side with excellent backside roughness and uniform thickness, high technology is required to minimize wafer defect whose material is expensive and easy to be broken.
