PURPOSE:To restrain coarse diamond abrasive grains from peeling and make service life in a wire longer as well as to improve the accuracy of finishing with no supply of slurry, by forming a second electrodeposited layer of the diamond abrasive grains on a first electrodeposited layer of the coarse diamond abrasive grains. CONSTITUTION:Coarse diamond abrasive grains 8 are electrodeposited on a wire or ribbon blank 7, setting it down to a first electrodeposited layer 9. Next, diamond abrasive grains 10 being considerably finer than the coarse diamond abrasive grains 8 are electrodeposited on this first electrodeposited layer 9, setting to down to a second electrodeposited layer 10. In consequence, these coarse diamond abrasive grains 8 conductive to actual cutting is hard to peel off, and cutting operations of a semiconductor monocrystal, a ceramic, etc., are performable in a highly accurate manner without any supply of slurry containing abrasive grains, so that service life in a sawing diamond electrodeposited wire or ribbon is prolongable. |
