Performance evaluation of diamond cutting tools when ultra precision grinding spherical part

Bondless diamond wheel is fabricated in UTM by depositing diamond on carbide substrate. The deposited diamond layer is only on the top of the substrate surface and having grain size up to 10 µm depending the parameters used during diamond coating process. In general, Grain size of abrasive wheel see...
