  • Abstract The Composite electro-plating in-process sharpening (CEPIS) method
    is employed to sharpen the grinder during the grinding process. However,
    the coating thickness using CEPIS method is always increasing. To
    overcome this disadvantage, the pluse reverse current with off time is
    applied to this method to grind the SiC and the diamond film, and it is
    called the Composite electro-plating and electrolyzing in-process
    sharpening (CEPELIS) method.
    Experiment results show that, when the reverse-pluse time increases,
    the growth rate of the coating film in the grinder becomes slower and
    looser and the roughness of the diamond fi lm is decreased slowly at the
    current density of 4.5 ASD. A two-stage CEPELIS method at reverse-pluse
    time of 1500 μs is used to grind the CVD diamond film. In this first stage, a
    grit size of 10 μm is used to conduct CEPELIS grinding for 120 min, and
    then the grit size of 3 μm for 120 min. Finally, a mirror-like surface on the
    diamond film with an surface roughness of 0.05 μm is obtained, and the
    growth rate of the coating film is slightly increased. On the other hand, the
    coating thickness can be maintained constant in grinding SiC process at
    highter operating range. In addition, a mirror-like surface of SiC with an
    average surface roughness of 0.06 μm can be obtained.
