Abstract
Forming efficiency and grinding ability of metal-bonded, resinoid-bonded and vitrified-bonded diamond wheels for V-profile groove grinding of fine ceramics are experimentally investigated, analyzing initial profile of formed wheels, wheel wear, stock removal, grinding force, number of cutting edges on working wheel surface and so on. Main results obtained are as follows : (1) Initial profile of formed metal-bonded diamond wheel dressed by rotary dresser is better than that dressed by GC stick grindstone, while grinding force in the case of rotary dresser is larger than that of GC stick grindstone. (2) Geometrical error of the V-profile formed on metal-bonded diamond wheel is large and grinding force with this wheel is large, but the rate of change in V-profile is small. (3) V-profile is easily formed on resinoid-bonded and vitrified-bonded diamond wheel and grinding forces with those wheels are small, but the rates of cange in V-profile are large.
