The outline of the effects in ultrasonic grinding by using the longitudinally ultrasonically vibrated grinding wheel was investigated (frequency : 20kc amplitude : max. 22μ, work peice : aluminum, copper, brass, high speed steel). The results are as follows : 1) It is found that the grinding wheel can be vibrated and revolved without any trouble by this described method. 2) This longitudinal ultrasonic grinding is more effective machining at lower speed. 3) The grinding resistance is decreased by increasing of amplitude or decreasing of grinding speed. 4) Owing to this ultrasonically vibrated wheel, powdery chips are scattered and residual chips are not observed on the surface of grinding wheel in spite of this low grinding speed. 5) The bur is not occurred at the machined surface edge for any soft materials.
