Abstract:

Vibrations from 60 to 40,000 cps were investigated for possible application to grinding. Direct vibration of the part being ground and vibration of the grinding wheel itself were used. Most successful in performance was the wheel vibrating in the 20,000 cps frequency range. Benefits to conventional grinding are lower grinding temperature, lower power to grind, greater grinding ratios, no impairment to surface finish, no impairment to mechanical properties as to cracks, fatigue or tensile strength, even though using harder wheels than those normally used. An internal, external and surface grinder was modified to an ultrasonic grinder by attaching an ultrasonic spindle which vibrated the special ultrasonic wheel and hub assembly.
