Peripheral longitudinal grinding (oscillation grinding) ... In internal cylindrical oscillation grinding, a radial infeed is performed first, followed by the oscillation movement, since the surface to be ground is usually narrower than the internal grinding wheel. For both oscillation grinding and plunge-grinding, care should be taken to ensure ...
